Role of nutrition in wound healing and nutritional recommendations for promotion of wound healing: a narrative review: Myoungjean Ju, Yoonhong Kim, Kyung Won Seo; Ann Clin Nutr Metab 2023;15(3):67-71. Published online December 1, 2023; DOI: https://doi.org/10.15747/ACNM.2023.15.3.67

Purpose: Addressing both malnutrition and wound healing requires strategic intervention. However, guidelines for adequate nutrition for a variety of wounds are lacking. Based on the latest literature review, we summarize the role of nutrition in each stage of wound healing and nutritional recommendations for wound healing.
Current concept: Wounds undergo three healing phases: inflammatory, proliferative, and remodeling. The inflammatory phase involves clotting and cleaning the wound. The proliferative phase builds the wound bed through tissue growth. In the remodeling phase, collagen strength increases. Proper nutrition is crucial throughout. During inflammation, calcium, vitamin K, A, and E, zinc, and proteins are essential. In proliferation, amino acids, B vitamins, lipids, zinc, and iron play key roles. During remodeling, vitamins C and E, zinc, and water are critical for collagen synthesis and skin cell maturation. Vulnerable groups like the elderly, newborns, and obese patients need proper nutrition for skin maintenance. For pressure ulcers with malnutrition risk, recommendations are 30–35 kcal/kg/day energy, 1.25–1.5 g/kg/day protein, and 30 mL/kg water. Supplements might be added if regular meals don’t meet needs. For diabetic foot ulcers, despite common deficiencies, the 2019 International Working Group on the Diabetic Foot advises against prioritizing nutritional interventions over standard care due to limited high-quality evidence.
Conclusion: Despite limited guidelines, nutrition assessment is vital for wound evaluation. A multidisciplinary approach is key, emphasizing nutrition’s role in wound healing. Implementing nutritional interventions tailored to the wound and the individual’s nutritional status is essential. This comprehensive strategy ensures the best wound care outcomes.

Recent advances in refeeding syndrome in critically ill patients: a narrative review: Sang Woo Ha, Suk-Kyung Hong; Ann Clin Nutr Metab 2024;16(1):3-9. Published online April 1, 2024; DOI: https://doi.org/10.15747/ACNM.2024.16.1.3

Abstract PDF ePub

Purpose: The aim of this article is to provide a narrative review of the most recent studies on refeeding syndrome (RS) in critically ill patients and to summarize recent advancements that can be referenced in the treatment of these patients.
Current concept: RS in critically ill patients is a potentially lethal nutrition-related condition leading to sudden death. Initiation of food intake after a period of fasting can trigger rapid electrolyte uptake due to increased insulin release, leading to a decline in serum electrolytes with thiamine. This depletion may cause severe complications, such as cardiac arrhythmias, respiratory failure, seizures, and even death. The incidence of RS varies significantly, ranging from 7.4%–89%. Despite updates in diagnostic criteria over time, there remains a crucial need for criteria applicable to critically ill patients with underlying disorders such as metabolic derangement and organ dysfunction. To prevent RS, it is strongly recommended to start food intake after a fast at 20%–25% of estimated goals, gradually increasing the intake over several days. Close monitoring and electrolyte supplementation—especially of phosphorus, potassium, magnesium, and thiamine—are crucial, especially in critically ill patients. If electrolyte imbalances persist, slowing down or halting the progression of nutrition should be considered.
Conclusion: Clinicians should continue their efforts to promptly identify high-risk patients and to provide prevention and treatment for RS, particularly during the initiation of nutritional therapy in critically ill patients. Developing evidence-based protocols through further well-designed research is essential for effectively managing critically ill patients at risk of RS.

Mental health and micronutrients: a narrative review: Hyun Wook Baik; Ann Clin Nutr Metab 2024;16(3):112-119. Published online December 1, 2024; DOI: https://doi.org/10.15747/ACNM.2024.16.3.112

Abstract PDF ePub

Purpose: It aims to summarizes the evidence for the association between specific individual nutrients and mental disorders, focusing on vitamin B12 and related B vitamins, vitamin D, probiotics, and zinc.
Current concept: Vitamin D deficiency is linked to depression, anxiety, and cognitive decline. Vitamin D enhances serotonin synthesis, has anti-inflammatory and neuroprotective effects, and regulates the hypothalamic-pituitary-adrenal axis and circadian rhythms. Vitamin B12 deficiency causes neurological dysfunction, mood disorders, cognitive decline, and psychotic symptoms, especially in the elderly. Vitamin B12 is involved in myelin formation, neurotransmitter synthesis, and preventing homocysteine-related neurodegeneration. Zinc deficiency affects neurotransmitters, neurogenesis, and antioxidant function, contributing to depression, anxiety, and cognitive impairment. Zinc supplementation improves symptoms and increases brain-derived neurotrophic factor levels. The gut-brain axis involves bidirectional communication between the gut microbiome and the central nervous system via the vagus nerve, enteric nervous system, immune system, and neuroendocrine pathways. Probiotics can modulate the gut microbiome to improve depression, anxiety, stress response, and cognitive function by influencing neurotransmitter production, reducing inflammation, and supporting the gut-brain connection.
Conclusion: Nutritional interventions, including vitamin D, B12, zinc, and probiotics, show promise as adjunctive therapies or preventive strategies for mental disorders. These nutrients have specific mechanisms of action on brain function and the gut-brain axis. Further research is needed to establish optimal dosage, timing, and administration methods for these nutritional approaches in supporting mental health.

A practical guide for enteral nutrition from the Korean Society for Parenteral and Enteral Nutrition: Part I. prescribing enteral nutrition orders: Ye Rim Chang, Bo-Eun Kim, In Seok Lee, Youn Soo Cho, Sung-Sik Han, Eunjung Kim, Hyunjung Kim, Jae Hak Kim, Jeong Wook Kim, Sung Shin Kim, Eunhee Kong, Ja Kyung Min, Chi-Min Park, Jeongyun Park, Seungwan Ryu, Kyung Won Seo, Jung Mi Song, Minji Seok, Eun-Mi Seol, Jinhee Yoon, Jeong Meen Seo, for KSPEN Enteral Nutrition Committee; Ann Clin Nutr Metab 2025;17(1):3-8. Published online April 1, 2025; DOI: https://doi.org/10.15747/ACNM.25.0002

Abstract PDF ePub

Purpose
This study aimed to develop a comprehensive practical guide for enteral nutrition (EN) designed to enhance patient safety and reduce complications in Korea. Under the leadership of the Korean Society for Parenteral and Enteral Nutrition (KSPEN), the initiative sought to standardize EN procedures, improve decision-making, and promote effective multidisciplinary communication.
Methods
The KSPEN EN committee identified key questions related to EN practices and organized them into seven sections such as prescribing, delivery route selection, formula preparation, administration, and quality management. Twenty-one experts, selected based on their expertise, conducted a thorough literature review to formulate evidence-based recommendations. Drafts underwent peer review both within and across disciplines, with final revisions completed by the KSPEN Guideline Committee. The guide, which will be published in three installments, addresses critical elements of EN therapy and safety protocols.
Results
The practical guide recommends that EN orders include detailed elements and advocates the use of electronic medical records for communication. Standardized prescription forms and supplementary safety measures are outlined. Review frequency is adjusted according to patient condition—daily for critically ill or unstable patients and as dictated by institutional protocols for stable patients. Evidence indicates that adherence to these protocols reduces mortality, complications, and prescription errors.
Conclusion
The KSPEN practical guide offers a robust framework for the safe delivery of EN tailored to Korea’s healthcare context. It emphasizes standardized protocols and interdisciplinary collaboration to improve nutritional outcomes, patient safety, and operational efficiency. Rigorous implementation and monitoring of adherence are critical for its success.

Abstract PDF Supplementary Material ePub

Purpose: Nutritional support for adult critically ill patients is essential due to the high risk of malnutrition, which can lead to severe complications. This paper aims to develop evidence-based guidelines to optimize nutritional support in intensive care units (ICUs).
Methods: The Grading Recommendations, Assessment, Development and Evaluation process was used to develop and summarize the evidence on which the recommendations were based. Clinical outcomes were assessed for seven key questions.
Results: We recommend the following: (1) initiate enteral nutrition (EN) within 48 hours after treatment as it is associated with improved outcomes, including reduced infection rates and shorter ICU stays; (2) early EN is preferred over early parenteral nutrition due to better clinical outcomes; (3) the use of supplementary parenteral nutrition to meet energy targets during the first week of ICU admission in patients receiving early EN is conditionally recommended based on patient-specific needs; (4) limited caloric support should be supplied to prevent overfeeding and related complications, particularly in the early phase of critical illness; (5) higher protein intake is suggested to improve clinical outcomes, such as muscle preservation and overall recovery; (6) additional enteral or parenteral glutamine is conditionally recommended against due to the lack of significant benefit and potential harm; and (7) fish oil-containing lipid emulsions is conditionally recommended due to their potential to enhance clinical outcomes, including reduced infection rates and shorter ICU stays.
Conclusion: These evidence-based recommendations can improve clinical outcomes and support healthcare providers in making informed decisions about nutritional interventions in the ICU.

Dysphagia and quality of life: a narrative review: Jung Mi Song; Ann Clin Nutr Metab 2024;16(2):43-48. Published online August 1, 2024; DOI: https://doi.org/10.15747/ACNM.2024.16.2.43

Abstract PDF ePub: Purpose: Dysphagia is a chronic health condition that causes impairment of eating and drinking functions. It occurs in various diseases such as stroke, neurodegenerative disease, brain tumor, and head and neck cancer, and can also occur during the normal aging process.
Current concept: As patients experience symptoms of dysphagia, they no longer feel the pleasure of eating, depression and anxiety increase, and self-esteem decreases. Prolonged loss of appetite can lead to malnutrition, which can lead to death due to serious complications such as aspiration pneumonia and airway obstruction. Dysphagia reduces quality of life by affecting basic activities of daily living, limitations in social life, nutritional deficiencies, and mood disorders.
Conclusion: Accordingly, I plan to conduct a literature review on the quality of life of patients with dysphagia. First, to determine the relationship between quality of life and sociodemographic, physical health, and mental health characteristics of patients with dysphagia. I also aim to review quality of life measurement tools and intervention programs for patients with dysphagia.

Development of a pre- and re-habilitation protocol for gastrointestinal cancer surgery: Eun Young Kim, Jung Hoon Bae, Jiseon Kim, Eun Joo Yang, Sang-Jae Park, In Kyu Lee, on behalf of the Task Force Team for Development and Trial Application of Pre/Rehabilitation Protocol in GI Cancer Surgery; Ann Clin Nutr Metab 2025;17(1):25-40. Published online April 1, 2025; DOI: https://doi.org/10.15747/ACNM.25.0001

Abstract PDF Supplementary Material ePub: Purpose
Surgical resection is the primary curative treatment for gastrointestinal (GI) cancer; however, it is associated with high postoperative complication rates and impaired recovery. Frailty, malnutrition, and sarcopenia increase morbidity and mortality, underscoring the need for perioperative rehabilitation programs. Standardized rehabilitation protocols during the perioperative period are currently lacking in Korea. We aimed to develop an evidence-based rehabilitation protocol for GI cancer patients to enhance postoperative outcomes and facilitate clinical implementation.
Methods
A multidisciplinary task force team comprising experts in surgery, clinical nutrition, and rehabilitation medicine conducted a systematic literature search and comprehensive review from 2012 to 2022 to develop a standardized pre- and re-habilitation protocol for GI cancer surgery. The protocol underwent external validation and subsequent refinements before being finalized through expert consensus.
Results
The protocol development process was organized into four consecutive phases: keyword selection, literature review and case report form development, initial protocol drafting, and external validation leading to the final version of the protocol. The final version of the rehabilitation protocol is presented in the main text and included as Supplements.
Conclusion
This protocol provides a standardized clinical guideline based on the latest evidence-based pre- and re-habilitation strategies and is designed for seamless integration into routine clinical practice. By facilitating proactive rehabilitation interventions, it aims to improve outcomes in GI cancer patients who are at high risk of postoperative complications, functional decline, and malnutrition.

Perioperative nutrition support: a narrative review: Rajeev Joshi, Asma Khalife; Ann Clin Nutr Metab 2023;15(2):40-45. Published online August 1, 2023; DOI: https://doi.org/10.15747/ACNM.2023.15.2.40

Abstract PDF ePub

Purpose: Proper nutrition and supplementation are paramount in surgical patients. Suboptimal nutrition status is increasingly recognized as an independent predictor of poor surgical outcomes. The purpose of this review is to highlight the need for nutritional protocols, with an emphasis on perioperative nutrition.
Current concept: Perioperative nutrition support is considered an adjunctive strategy in most centers, although it is proven to be the key in improving surgical outcomes. There is a need to increase the standards and formulate policies and protocols to optimize perioperative nutrition support. Components of perioperative nutrition include nutritional screening and assessment, prehabilitation, preoperative metabolic optimization and carbohydrate loading, postoperative early enteral feeding and perioperative parenteral nutrition, immunonutrition and micronutrients, and oral nutritional supplementation vs. hospital-based kitchen feeds. Supplemental parenteral nutrition becomes valuable when enteral nutrition alone cannot fulfil energy needs. In patients in the surgical intensive care unit who are dealing with hemodynamic instability, high levels of serum lactate unrelated to thiamine deficiency, acidosis, significant liver dysfunction, high blood sugar, and high blood lipid levels, parenteral nutrition must be started with caution. In the post-surgery care ward, it is advisable to administer up to 30 kcal/kg/day and 1.2–2 g/kg/day of protein.
Conclusion: The positive impact of comprehensive nutritional support and the importance of setting and executing standards must be highlighted. Emphasis should be placed on overcoming existing challenges in implementing nutrition therapy in current surgical practice, as better perioperative nutrition supports better surgical outcomes.

Pathogenesis, risk factors, and management of postoperative delayed gastric emptying after distal gastrectomy: a narrative review: Cheong Ah Oh; Ann Clin Nutr Metab 2025;17(1):9-17. Published online April 1, 2025; DOI: https://doi.org/10.15747/ACNM.25.0007

Abstract PDF ePub: Purpose
This narrative review elucidates the complex pathogenesis, key risk factors, and effective management strategies for postoperative delayed gastric emptying (DGE) following distal gastrectomy with D2 lymphadenectomy, a definitive procedure for middle and lower gastric cancer. It also explores opportunities for improved prevention and innovative treatment options. Current concept: DGE significantly disrupts gastric motility and presents with symptoms such as early satiety, postprandial fullness, nausea, vomiting, and gastric atony. Although rarely fatal, DGE hampers oral intake, prolongs hospital stays, and diminishes quality of life. Current evidence indicates that DGE is a multifactorial disorder resulting from an interplay of vagal nerve disruption, damage to smooth muscle and interstitial cells of Cajal, imbalances in gastrointestinal hormones, and postoperative gut microbiome dysbiosis. Patient-specific factors, including advanced age, poor nutritional status, diabetes, and preoperative pyloric obstruction, along with surgical factors (most notably Billroth II reconstruction), further increase the risk of DGE. Management involves dietary modifications, prokinetic agents (such as metoclopramide and selective 5-HT4 agonists like prucalopride), and gastric decompression.
Conclusion
DGE is a challenging complication following gastrectomy that demands a deeper understanding of its underlying mechanisms to improve patient outcomes. Emerging therapies, including microbiota modulation and advanced pharmacological agents, offer promising new treatment avenues.

Perioperative nutritional management to improve long-term outcomes in critically ill perioperative organ transplant patients: a narrative review: Toshimi Kaido; Ann Clin Nutr Metab 2025;17(1):18-24. Published online April 1, 2025; DOI: https://doi.org/10.15747/ACNM.25.0005

Abstract PDF ePub: Purpose
This review examines the significance of perioperative nutritional management in organ transplantation, with a particular focus on liver transplantation. Organ transplant recipients often experience malnutrition and sarcopenia due to nutritional and metabolic abnormalities associated with organ dysfunction. Because transplantation is a highly invasive procedure, optimizing perioperative nutritional care is critical for improving short-term outcomes and reducing postoperative infection-related mortality. Current concept: Recent clinical investigations have shown that liver transplant recipients, who are frequently afflicted with end-stage liver disease and uncompensated cirrhosis, are particularly vulnerable to protein-energy malnutrition and secondary sarcopenia. Our analysis identified low pre-transplant nutritional status and the absence of preoperative branched-chain amino acid supplementation as independent risk factors for post-transplant sepsis. In response, we developed a customized nutritional therapy protocol that incorporates precise body composition analysis, serial measurements of biochemical markers (including prealbumin, zinc, and the branched-chain amino acid/tyrosine ratio), and targeted supplementation with branched-chain amino acids, zinc acetate, and synbiotics. Early initiation of enteral nutrition coupled with postoperative rehabilitative interventions resulted in improved outcomes. In addition, stratified body composition parameters correlated with survival differences and informed revised transplantation criteria.
Conclusion
Tailored perioperative nutritional management and rehabilitative strategies are essential for improving early postoperative outcomes in liver transplantation. These findings underscore the need for proactive nutritional assessment and intervention, which may represent a breakthrough in transplant prognosis. Future research should refine nutritional protocols and integrate novel biomarkers, while education and interdisciplinary collaboration remain crucial for enhancing transplant outcomes and reducing complications.

Preoperative consumption of a carbohydrate drink before laparoscopic cholecystectomy is safe and beneficial in Korea: a non-randomized controlled study: Yoo Jin Choi, Yoonhyeong Byun, Seong Mi Yang, Ho-Jin Lee, Hongbeom Kim; Ann Clin Nutr Metab 2023;15(1):15-21. Published online April 1, 2023; DOI: https://doi.org/10.15747/ACNM.2023.15.1.15

Abstract PDF Supplementary Material ePub

Purpose: Overnight fasting prior to elective surgery is the traditional way of avoiding the risk of aspiration during anesthesia induction. However, it causes mental and metabolic stress to patients. Therefore, we investigated the safety and potential benefits of the preoperative consumption of a carbohydrate drink.
Methods: This was a single-center prospective, nonrandomized study with questionnaire. Patients scheduled for elective laparoscopic cholecystectomy were included. There was no restriction on age, underlying diseases, and biliary drainage prior to surgery. They were preoperatively given either a carbohydrate drink or were instructed to fast from midnight before surgery. Perioperative emotional status was measured using the visual analog scale.
Results: The 132 patients completed the questionnaire, with 68 receiving the carbohydrate drink and 64 following nil per oral after-midnight instruction. There were no postoperative complications related to preoperative drink consumption or the cholecystectomy procedure itself in both groups. There were no significant differences in all the assessed feelings postoperatively except that preoperative discomforts, such as hunger and thirst, were significantly more alleviated in the group of preoperative consumption of a carbohydrate drink.
Conclusion: Preoperative consumption of a carbohydrate drink was found to be safe and effective in alleviating preoperative discomfort in elective surgery patients, including older patients and those with underlying comorbidities, who were at greater risk for aspiration. Therefore, we recommend considering preoperative drink consumption as an alternative to traditional overnight fasting in elective surgery patients.

Comparison of efficacy of enteral versus parenteral nutrition in patients after esophagectomy in Malaysia: a prospective cohort study: Ramizah Mohd Shariff, Sze Chee Tee, Shukri Jahit Mohammad, Khei Choong Khong; Ann Clin Nutr Metab 2025;17(1):41-49. Published online April 1, 2025; DOI: https://doi.org/10.15747/ACNM.24.016

Graphical Abstract Abstract PDF: Purpose
This study aims to assess the effectiveness of enteral versus parenteral feeding in patients after esophagectomy.
Methods
This a prospective cohort study of post-esophagectomy intensive care unit (ICU) patients over 12 months in the National Cancer Institute, Malaysia. Early enteral feeding followed the Enhanced Recovery After Surgery protocol, and parenteral nutrition (PN) was considered if there was a risk for conduit ischemia. It compared the effectiveness of enteral versus PN following esophagectomy, and assessed the correlations between biochemical nutritional markers and hospital lengths of stay or ventilation days.
Results
It included two cohorts receiving PN (n=11) or enteral nutrition (EN) (n=11) following elective esophagectomy. Preoperative weight, body mass index, and Subjective Global Assessment were higher in the EN group (P=0.033, P=0.021, P=0.031, respectively). Nutritional interruption occurred more frequently in the EN group (63.7%) compared to the PN group (P=0.001). Mean levels of energy and protein received were 93.1 kcal/kg and 1.4 g/kg for PN versus 92.4 kcal/kg and 1.2 g/kg for EN (P=0.893, P=0.036). The median lengths of ICU stay (P=0.688) and postoperative stay (P=0.947) between groups showed no significant difference. In addition, 30-day mortality (P=0.214) and other postoperative complications (P>0.05) were comparable in the two groups.
Conclusion
Early initiation of supplementary PN due to significant interruption in EN led to higher protein intake compared to the EN group. However, there were no significant differences in postoperative outcomes, including 30-day mortality, ICU length of stay, and ventilation days. PN ensures adequate nutritional intake, especially in terms of protein delivery, without adversely affecting postoperative recovery and clinical outcomes.

Effects of enteral nutrition formulas with varying carbohydrate amounts on glycemic control in diabetic mice: Yukari Miki, Kazuo Hino; Ann Clin Nutr Metab 2025;17(1):85-93. Published online April 1, 2025; DOI: https://doi.org/10.15747/ACNM.25.0006

Abstract PDF ePub: Purpose
This study evaluated the effects of an 8‑week liquid diets with different carbohydrate contents–64% energy in HINE E‑Gel (ST) and 50% energy in HINE E‑Gel LC (LC)–on glycemic control and nutritional status in a mouse model of type 2 diabetes mellitus (db/db mice). The objective was to determine whether reducing carbohydrate intake within the Dietary Reference Intakes for Japanese people improves glycemic control indices, addressing the evidence gap in regarding the long‑term safety and efficacy of low‑carbohydrate enteral nutrition in patients with diabetes.
Methods
db/db mice (n=10 per group) and non‑diabetic db/m mice (n=4) as controls were fed ST, LC, or AIN‑93G diets ad libitum for 8 weeks. The diets primarily differed in carbohydrate content (64% in ST vs. 50% in LC). Blood glucose and glycated hemoglobin (HbA1c), plasma glucose and glycoalbumin, organ weights, and renal function markers were measured weekly or at 4 and 8 weeks. Histopathological examinations of the liver and kidneys were performed at 8 weeks.
Results
At 8 weeks, the LC group showed significantly lower plasma glucose (P=0.0051) and glycoalbumin (P=0.0013) levels compared to the ST group, with a trend toward lower HbA1c (P=0.0514). Although body weight was significantly higher in the LC group (P=0.0038), there were no significant differences between the ST and LC groups in caloric intake, renal function, or histopathological findings.
Conclusion
Reducing carbohydrate intake to 50% of total energy within dietary guidelines may improve glycemic control in diabetic mice, suggesting the need for further long‑term evaluation for clinical applications.

Association between decreased dietary intake during hospitalization and long-term weight loss in postoperative gastric cancer patients over 75 years of age: a retrospective cohort study: Daiki Tabe, Isao Miyajima, Akira Tsukada; Ann Clin Nutr Metab 2025;17(1):75-84. Published online April 1, 2025; DOI: https://doi.org/10.15747/ACNM.25.0004

Abstract PDF ePub: Purpose
Weight loss following gastrectomy is a significant concern, and maintaining adequate nutrition is necessary, especially given the growing number of older adult patients. This study examined the relationship between postoperative food intake and long-term weight loss in postgastrectomy patients aged ≥75 years.
Methods
Out of 88 patients who underwent gastrectomy for gastric cancer at our institute, 46 were aged ≥75 years. These patients were divided into two groups: one with an average energy intake exceeding 50% of the basal metabolic rate and one with an intake below 50% of the basal metabolic rate. The percentage change in body weight up to 6 months post-surgery was compared between the groups.
Results
In the group with higher dietary intake, the rate of weight change at 3 and 6 months postoperatively was lower, and fewer patients received postoperative adjuvant chemotherapy.
Conclusion
Poor postoperative food intake may serve as a predictor of weight loss up to 3 months following surgery in postgastrectomy patients aged ≥75 years.

Perioperative nutritional practice of surgeons in Korea: a survey study: Ji-Hyeon Park, Mi Ran Jung, Sang Hyun Kim, Hongbeom Kim, Gyeongsil Lee, Jae-Seok Min, Heung-Kwon Oh, Jung Hoon Bae, Yoona Chung, Dong-Seok Han, Seung Wan Ryu, The External Relation Committee of the Korean Society of Surgical Metabolism and Nutrition; Ann Clin Nutr Metab 2024;16(3):134-148. Published online December 1, 2024; DOI: https://doi.org/10.15747/ACNM.2024.16.3.134

Abstract PDF Supplementary Material ePub: Purpose: Enhanced recovery after surgery (ERAS) protocols advocate reduced fasting and early nutrition to improve recovery in surgical patients. However, data on ERAS implementation among Korean surgeons performing major abdominal surgeries remain sparse.
Methods: A survey conducted by the External Relation Committee of the Korean Society of Surgical Metabolism and Nutrition assessed perioperative nutritional practices among 389 Korean general surgeons from February to September 2023. The survey covered preoperative fasting, carbohydrate drinks, nasogastric tube use, postoperative dietary progression, parenteral nutrition (PN), and oral supplements, yielding 551 responses stratified by specialty.
Results: More than 80% of respondents practiced “midnight NPO (Nil Per Os)” fasting, often at the anesthesiology department’s request, while 70%–80% reported no use of preoperative carbohydrate drinks. Most surgeons began dietary progression with water on postoperative day one, advancing to a liquid or soft diet by day two. PN was routinely prescribed by 49% of respondents, with a common dosage of 1,000–1,500 kcal/d. Oral supplements were selectively provided, with 21% of surgeons prescribing them universally.
Conclusion: The results reveal significant variability in perioperative nutrition practices across Korean surgical specialties, with many adhering to traditional practices despite ERAS guidelines. These findings highlight a need for standardized guidelines in Korea to optimize perioperative nutritional support and improve patient recovery outcomes following major abdominal surgeries.

The enteral feeding tube access route in esophageal cancer surgery in Japan: a retrospective cohort study: Hiroyuki Kitagawa, Keiichiro Yokota, Tsutomu Namikawa, Kazuhiro Hanazaki; Ann Clin Nutr Metab 2025;17(1):58-65. Published online April 1, 2025; DOI: https://doi.org/10.15747/ACNM.25.0003

Graphical Abstract Abstract PDF ePub: Purpose
Feeding catheter jejunostomy is a useful access route for early enteral nutrition during esophageal cancer surgery. However, it may lead to postoperative bowel obstruction associated with feeding jejunostomy (BOFJ). To prevent BOFJ, we introduced feeding catheter duodenostomy via the round ligament in 2018. This study aimed to compare the incidence of BOFJ and postoperative body weight changes between feeding catheter jejunostomy and duodenostomy.
Methods
A total of 109 patients who underwent thoracoscopic esophagectomy and gastric tube reconstruction for esophageal cancer at Kochi Medical School Hospital between March 2013 and November 2020 were included. Preoperative patient characteristics (age, sex, preoperative weight, body mass index, cancer stage, and preoperative treatment), surgical outcomes (operative time, blood loss, and postoperative complications [wound infection, pneumonia, anastomotic leakage, BOFJ]), and body weight changes at 1, 3, 6, and 12 months post-surgery were compared between the jejunostomy (J) and duodenostomy (D) groups.
Results
The D group consisted of 35 patients. No significant differences were observed between the groups regarding age, sex, weight, body mass index, cancer stage, operative time, postoperative complications, or duration of tube placement. However, the D group had a significantly lower rate of preoperative chemotherapy (45.7% vs. 78.4%, P=0.001) and lower operative blood loss (120 mL vs. 150 mL, P=0.046) than the J group. All 12 cases of BOFJ occurred in the J group. Furthermore, the D group experienced a significantly lower weight loss ratio at 1 month postoperatively (93.9% vs. 91.8%, P=0.039).
Conclusion
In thoracoscopic esophagectomy, feeding duodenostomy may prevent bowel obstruction and reduce early postoperative weight loss without increasing operative time compared with feeding catheter jejunostomy.

Impact of postoperative nutritional status on the patients’ clinical outcomes and knee biomechanics following total knee arthroplasty in Japan: a prospective cohort study: Kenichi Kono, Tetsuya Tomita, Takaharu Yamazaki, Masashi Tamaki, Shuji Taketomi, Ryota Yamagami, Reo Inoue, Yuki Taniguchi, Sakae Tanaka, Kazuhiko Fukatsu; Ann Clin Nutr Metab 2025;17(1):50-57. Published online April 1, 2025; DOI: https://doi.org/10.15747/ACNM.24.019

Graphical Abstract Abstract PDF Supplementary Material: Purpose
The impact of postoperative nutritional status on clinical outcomes and biomechanics following total knee arthroplasty remains largely unknown. This study aimed to assess this question using the prognostic nutritional index to evaluate the nutritional status of orthopedic participants.
Methods
Patients with knee osteoarthritis who underwent total knee arthroplasty (n=49) in Japan were divided into two groups based on their 1-week postoperative prognostic nutritional index. Group L patients had a prognostic nutritional index <40, whereas Group H comprised patients with a prognostic nutritional index ≥40. Postoperative improvements in Knee Injury and Osteoarthritis Outcome Score were evaluated. The patients performed squats under single-fluoroscopic surveillance in the sagittal plane for biomechanical evaluation. A two-dimensional/three-dimensional registration technique was employed to measure the tibiofemoral kinematics. The axial rotation of the femoral component relative to the tibial component and the anteroposterior translation of the medial and lateral femorotibial contact points were measured.
Results
Group H showed significantly higher pain scores than Group L at 12 and 36 months postoperatively and a significantly higher symptom score at 36 months postoperatively. The kinematic comparison revealed that the axial external rotation in Group L was larger than that in Group H from 70° to 80° with flexion. Moreover, in the medial anteroposterior translation, Group L was more anteriorly located than Group H, with flexion beyond 30°.
Conclusion
The results suggest that a high postoperative nutritional status significantly improved pain and other symptoms and was associated with better knee biomechanics following total knee arthroplasty.

Role of preoperative immunonutrition in patients with colorectal cancer: a narrative review: Soo Young Lee, Hyeung-min Park, Chang Hyun Kim, Hyeong Rok Kim; Ann Clin Nutr Metab 2023;15(2):46-50. Published online August 1, 2023; DOI: https://doi.org/10.15747/ACNM.2023.15.2.46

Abstract PDF ePub

Purpose: Colorectal cancer surgery presents challenges due to surgical stress and immunosuppression, leading to postoperative complications. Nutrition is crucial for colorectal cancer patients who are prone to malnutrition. This study aims to provide a comprehensive review of the role of preoperative immunonutrition in colorectal cancer surgery.
Current concept: Preoperative immunonutrition, consisting of immunonutrients such as arginine, ω-3 fatty acids, and nucleotides, has emerged as a potential strategy to enhance surgical outcomes by modulating immune responses and reducing complications. Current guidelines recommend preoperative oral nutritional supplements for major abdominal surgery and immunonutrition for nutritionally high-risk patients. Meta-analysis have demonstrated significant decreases in infectious complications and hospital stay durations with preoperative immunonutrition. However, limitations such as publication bias and heterogeneity in the previous studies should be considered. Further research should focus on the optimal timing, duration, and amount of immunonutrition; the patient populations that would benefit most; and the integration of immunonutrition into enhanced recovery after surgery protocols.
Conclusion: While preoperative immunonutrition shows promise, additional research is crucial to refine protocols and establish optimal clinical practice utilization.

Micronutrient deficiencies in copper, zinc, and vitamin D as predictors of clinical outcomes in critically ill surgical patients in Korea: a retrospective cohort study: Jiae Kim, Yanghee Jun, Ye Rim Chang, Jong-Kwan Baek, Hak-Jae Lee, Hyewon Han, Suk-Kyung Hong; Ann Clin Nutr Metab 2024;16(3):158-167. Published online December 1, 2024; DOI: https://doi.org/10.15747/ACNM.2024.16.3.158

Abstract PDF ePub: Purpose: To investigate the prevalence of copper, zinc, and vitamin D deficiencies in surgical intensive care unit (SICU) patients and the associations between those deficiencies and clinical outcomes.
Methods: We conducted a retrospective study of 210 patients admitted to the SICU of Asan Medical Center between June 2020 and June 2022. Micronutrient levels were measured within 7 days of SICU admission. Primary outcomes were the mortality rate, length of SICU stay, hospital stay duration, and mechanical ventilation duration.
Results: Copper deficiency was found in 35% (68/193), zinc deficiency in 52% (100/193), and severe vitamin D deficiency in 46% (82/179) of patients. Copper-deficient patients showed a significantly higher mortality rate (25.0% vs. 12.8%, P=0.044), longer hospital stays (57.8±47.0 vs. 45.2±36.6 days, P=0.041), and extended mechanical ventilation duration (26.9±23.3 vs. 18.8±15.7 days, P=0.012). Zinc deficiency was associated with higher C-reactive protein levels (16.2±9.5 vs. 11.5±8.8 mg/dL, P=0.001) and lower prealbumin levels (6.5±2.8 vs. 9.9±5.6 mg/dL, P<0.001). Severe vitamin D deficiency (<10 ng/mL) was not significantly associated with mortality or other clinical outcomes (mortality: <10 ng/mL vs. ≥10 ng/mL, 13% vs. 18%, P=0.583).
Conclusion: Micronutrient deficiencies are prevalent in SICU patients. Copper deficiency significantly correlated with poor clinical outcomes, and zinc deficiency showed a strong association with inflammatory markers. Early assessment and supplementation of micronutrients could be beneficial for critically ill surgical patients.

Definition, assessments, and current research on sarcopenia in children: a narrative review: Min-Jung Bang; Ann Clin Nutr Metab 2024;16(2):49-56. Published online August 1, 2024; DOI: https://doi.org/10.15747/ACNM.2024.16.2.49

Abstract PDF ePub: Purpose: Sarcopenia is a well-established prognostic factor for the clinical outcomes of adult patients with cancer and chronic diseases and correlates with increased intensive care unit admissions and prolonged hospital stays. However, research on sarcopenia in children is limited due to its undefined criteria and a lack of studies exploring its impact on clinical outcomes.
Current concept: The challenges in pediatric sarcopenia research include the absence of standardized body composition methods to quantify muscle mass and muscular function, as well as inconsistencies in definitions. Additionally, there is a lack of age- and gender-specific normative data, particularly for young children and infants. Most studies also lack assessments of muscle function, which can lead to bias and misclassification of sarcopenia. The field is further hindered by poor study quality, limited outcome-focused research, and a dearth of longitudinal data. While some studies suggest that various diseases can affect children’s lean muscle mass, few have linked changes in muscle mass to clinical outcomes.
Conclusion: The existing literature on pediatric sarcopenia and its relationship with medical and surgical outcomes is sparse and indicates poorer outcomes associated with sarcopenia. Although extensive research has established a link between sarcopenia and adverse outcomes in adults, information on its impact in pediatric populations remains scarce. Further studies are needed to elucidate the association between muscle mass and outcomes in pediatric surgical patients.

Triglyceride-glucose index predicts future metabolic syndrome in an adult population, Korea: a prospective cohort study: Min-Su Park; Ann Clin Nutr Metab 2024;16(3):168-172. Published online December 1, 2024; DOI: https://doi.org/10.15747/ACNM.2024.16.3.168

Abstract PDF ePub: Purpose: The triglyceride-glucose (TyG) index has been proposed as a reliable surrogate marker for insulin resistance. This study aimed to assess the utility of the TyG index in predicting the future presence of metabolic syndrome (MetS) in an adult population.
Methods: A total of 3,241 adults aged 40–70 years were included in this cross-sectional study. MetS was diagnosed based on the modified National Cholesterol Education Program Adult Treatment Panel III criteria, which requires the presence of at least three of the following components: abdominal obesity, elevated blood pressure, dysglycemia, hypertriglyceridemia, and low high-density lipoprotein cholesterol.
Results: In comparison to the homeostasis model assessment of insulin resistance (HOMA-IR), the TyG index exhibited superior diagnostic performance, with a higher area under the receiver operating characteristic curve of 0.854 vs. 0.702 for HOMA-IR. The 95% confidence interval for the TyG index was narrower, reflecting a more consistent predictive ability. Sensitivity for the TyG index was 79.7%, while specificity was 79.3%, compared to HOMA-IR, which showed a sensitivity of 52.7% and specificity of 78.3%.
Conclusion: The TyG index is a highly effective and robust tool for identifying individuals at risk for MetS, demonstrating superior sensitivity and predictive accuracy over HOMA-IR. This index could be a valuable clinical marker for early detection of MetS, aiding in the prevention and management of associated metabolic disorders.

Changes in perceptions of taste after bariatric surgery: a narrative review: Young Suk Park; Ann Clin Nutr Metab 2024;16(3):120-124. Published online December 1, 2024; DOI: https://doi.org/10.15747/ACNM.2024.16.3.120

Abstract PDF ePub: Purpose: Bariatric surgery effectively treats severe obesity, leading to significant weight loss and improved comorbidities. However, many patients experience postoperative alterations in taste perception, affecting food selection and eating behavior. This narrative review examines the current understanding of taste perception changes following bariatric surgery, including patterns, potential mechanisms, impact on weight loss outcomes, and implications for patient care.
Current concept: Changes in taste perception are frequently reported after bariatric procedures, with prevalence rates from 36% to 72%. Common alterations involve decreased preference and increased sensitivity to sweet and fatty tastes, potentially leading to reduced calorie intake and healthier food choices. Persistence of these changes varies and may depend on surgery type, with Roux-en-Y gastric bypass patients often experiencing more substantial effects than sleeve gastrectomy patients. Potential mechanisms include alterations in gut hormone secretion (e.g., GLP-1, peptide YY, ghrelin), modifications in neural pathways (e.g., vagus nerve), and shifts in the gut microbiome. These factors may collectively influence taste sensitivity and preferences, contributing to weight loss outcomes. Altered reward processing may reduce the appeal of high-calorie foods.
Conclusion: Alterations in taste perception are common after bariatric surgery and may significantly impact dietary behaviors, weight loss, and quality of life. While exact mechanisms are not fully understood, changes in gut hormones, neural pathways, and microbiota are likely involved. Patient counseling and postoperative management of bariatric surgery patients should address potential changes in taste. Further research is needed to elucidate the long-term impacts of taste alterations on weight-loss maintenance and nutritional status.

Changes in mineral and vitamin profiles after bariatric surgery in Korea: a before and after study: Jong Seob Park, Sang-Moon Han; Ann Clin Nutr Metab 2023;15(2):51-56. Published online August 1, 2023; DOI: https://doi.org/10.15747/ACNM.2023.15.2.51

Abstract PDF ePub: Purpose: Bariatric surgery induces nutritional deficiencies that require long-term monitoring and supplementation. This study aimed to evaluate the status of vitamins and minerals pre-operation and 2 years post-operation and to compare the findings according to type of bariatric surgery.
Methods: The study enrolled 302 patients who underwent bariatric surgery, adjustable gastric band (AGB), sleeve gastrectomy (SG), or Roux-en-Y gastric bypass (RYGB) between 2013 and 2017 in the CHA Gangnam Medical Center and the Seoul Medical Center, Korea. Minerals and vitamin status was assessed at baseline (pre-operatively) until 2 years after bariatric surgery.
Results: Mean age was 34.1±8.3 years, 256 patients (84.8%) were female, and mean body mass index was 35.3±5.7 kg/m². Vitamin B1, vitamin B12, and folic acid levels were significantly different at 1 and 2 years after surgery compared to baseline. Hemoglobin, hematocrit, high-density lipoprotein, iron, calcium, and magnesium levels did not differ significantly during the study period.
Conclusion: Although enrolled patients had no clinical symptoms of nutritional deficiences, several indicators related to nutrition decreased at 2 years after bariatric surgery. Despite variations in the alteration of laboratory results across three surgical interventions, namely SG, AGB, and RYGB, a consistent reduction in fasting blood sugar was observed subsequent to the surgical procedures.

The impact of nutritional intervention by a nutrition support team on extrauterine growth restriction in very low birth weight infants in Korea: a retrospective cohort study: Seung Yun Lee, Hye Su Hwang, Waonsun Im, Hyojoung Kim, Mi Lim Chung; Ann Clin Nutr Metab 2024;16(3):149-157. Published online December 1, 2024; DOI: https://doi.org/10.15747/ACNM.2024.16.3.149

Abstract PDF ePub: Purpose: Achieving proper weight gain through adequate nutrition is critically important in very low birth weight (VLBW) infants. Despite recent active nutritional interventions, growth restriction is still common in VLBW infants. We aimed to determine whether nutritional intervention by a nutrition support team (NST) mitigated extrauterine growth restriction (EUGR) in VLBW infants.
Methods: We retrospectively reviewed the medical records of VLBW infants admitted to Haeundae Paik Hospital between March 2010 and February 2024. EUGR was defined as a decrease in the weight-for-age-z-score>1.2 from birth to the postconceptional age of 36 weeks, using Fenton growth charts.
Results: Among the 603 enrolled VLBW infants, 434 (72.0%) were diagnosed with EUGR. When comparing the control and nutritional intervention groups, the incidence of EUGR was significantly lower in infants in the intervention group (80.6% vs. 62.8%, P<0.00). Intervention group infants started enteral feeding earlier and reached half and full enteral feeding earlier (P<0.05). In addition, intravenous protein and lipid supply started sooner, increased at a faster rate, and reached peak concentrations sooner in the intervention group (P<0.05).
Conclusion: Nutritional intervention by an NST resulted in a significant decrease in the development of EUGR in VLBW infants.

Incidence and risk factors of nonalcoholic fatty liver disease after pancreaticoduodenectomy in Korea: a multicenter retrospective cohort study: Chang-Sup Lim, Hongbeom Kim, In Woong Han, Won-Gun Yun, Eunchae Go, Jaewon Lee, Kyung Chul Yoon, So Jeong Yoon, Sang Hyun Shin, Jin Seok Heo, Yong Chan Shin, Woohyun Jung; Ann Clin Nutr Metab 2024;16(3):125-133. Published online December 1, 2024; DOI: https://doi.org/10.15747/ACNM.2024.16.3.125

Abstract PDF ePub: Purpose: This study aimed to investigate the incidence, risk factors, and clinical course of nonalcoholic fatty liver disease (NAFLD) following pancreaticoduodenectomy, focusing on the role of adjuvant chemotherapy and other metabolic changes.
Methods: A retrospective analysis was conducted on 189 patients who underwent pancreaticoduodenectomy between 2013 and 2016. NAFLD was diagnosed using computed tomography (CT) imaging, defined as a liver-to-spleen attenuation ratio <0.9. Sarcopenia and sarcopenic obesity were assessed using preoperative CT scans. Logistic regression analysis was performed to identify risk factors for NAFLD development.
Results: The cumulative incidence of NAFLD increased over time, with rates of 15.9% at one year, 20.4% at three years, and 35.2% at five years post-pancreaticoduodenectomy. Adjuvant chemotherapy was identified as the only significant independent predictor of NAFLD development (odds ratio, 2.74; 95% confidence interval, 1.16-6.70; P=0.023). No significant associations were found between NAFLD and pancreatic enzyme replacement therapy (PERT), sarcopenia, or sarcopenic obesity. Serial analysis of NAFLD status in long-term survivors revealed dynamic changes, with some patients experiencing spontaneous remission or recurrence.
Conclusion: NAFLD is a common, progressive complication following pancreaticoduodenectomy, particularly in patients receiving adjuvant chemotherapy. Although no significant associations with PERT or sarcopenia were observed, these areas warrant further investigation. Long-term monitoring and targeted management strategies are recommended to address NAFLD in this population. Future prospective studies are needed to elucidate the natural history and contributing factors of NAFLD after pancreaticoduodenectomy.

Comparative assessment of nutritional characteristics of critically ill patients at admission and discharge from the neurosurgical intensive care unit in Korea: a comparison study: Eunjoo Bae, Jinyoung Jang, Miyeon Kim, Seongsuk Kang, Kumhee Son, Taegon Kim, Hyunjung Lim; Ann Clin Nutr Metab 2023;15(3):97-108. Published online December 1, 2023; DOI: https://doi.org/10.15747/ACNM.2023.15.3.97

Abstract PDF ePub

Purpose: Patients in neurosurgical (NS) intensive care units (ICUs) experience considerable energy and protein deficits associated with adverse outcomes. This study aimed to compare the nutritional status of patients at admission to (baseline) and discharge from the NS ICU.
Methods: This was a single-center, retrospective, before and after study of patients admitted in the NS ICU of the CHA Bundang Medical Center, from January 31, 2019, to February 28, 2020. All anthropometric data, biochemical data, clinical data, and dietary data were collected during the NS ICU stay. Specifically, we investigated the cumulative caloric deficit rate, phase angle and skeletal muscle index as indicators of lean muscle mass, and nitrogen balance according to demographic and clinical characteristics.
Results: A total of 140 NS patients were studied. Calf circumference decreased from 31.4±4.2 cm at baseline to 30.2±4.0 cm at discharge (P<0.001). Energy supply rate increased from 44.4% at baseline to 89.2% at discharge. Phase angle (PhA) patients with an modified Nutrition Risk in the Critically ill (mNUTRIC) score≤5 group had significantly lower PhA values than those with an mNUTRIC score>5 (P=0.005).
Conclusion: Although clinical and dietary parameters of patients in the NS ICU improved from baseline to discharge, anthropometric and biochemical markers of lean muscle mass and nutritional status decreased. PhA and nitrogen balance difference values were significantly different between those with an mNUTRIC score≤5 and those with an mNUTRIC score>5. These data indicate that the nutritional risk of critically ill patients increases during hospitalization in the NS ICU.
