Body composition assessment using bioelectrical impedance analysis and computed tomography in patients who underwent pancreatoduodenectomy in Korea: a before and after study: Juwan Kim, Seung-seob Kim, Ho Kyoung Hwang, Chang Moo Kang, Kyung Sik Kim, Sung Hyun Kim; Ann Clin Nutr Metab 2023;15(3):72-80. Published online December 1, 2023; DOI: https://doi.org/10.15747/ACNM.2023.15.3.72

Abstract PDF Supplementary Material: Purpose: This study focuses on the need for standardized body composition measurements in the hepatobiliary-pancreatic field. It evaluates and compares the effectiveness of bioelectrical impedance analysis (BIA) and computed tomography (CT) scans in assessing body composition of patients undergoing pancreatoduodenectomy (PD), aiming to establish correlations among different body composition indexes.
Methods: Ninety-seven patients who underwent PD between August 2022 and March 2023, were enrolled in this study. Muscular and fatty parameters related to BIA and CT were assessed both preoperatively and on postoperative day 6. The correlation between each parameter related to muscle fat was analyzed according to the measurement modalities.
Results: There was an increase of skeletal muscle area (SMA), total muscle area, and low attenuated muscle area after surgery. Skeletal muscle mass (SMM) measured using BIA exhibited a strong correlation with the SMA and normal attenuated muscle area (NAMA) measured using CT (r=0.86, P<0.001; r=0.76, P<0.001). The trunk muscle measured using BIA demonstrated moderate to strong correlations with SMA and NAMA measured using CT (r=0.84 P<0.001; r=0.73, P<0.001). Body fat measured using BIA and total fat area (TFA) measured using CT showed strong correlations (r=0.74, P<0.001). In the postoperative analysis, a similar trend was observed (SMM vs. SMA: r=0.80, P<0.001; SMM vs. NAMA: r=0.70, P<0.001), (trunk muscle vs. SMA: r=0.79, P<0.001; trunk muscle vs. NAMA: r=0.69, P<0.001), and (body fat vs. TFA: r=0.83, P<0.001).
Conclusion: BIA, akin to CT, serves as a valuable tool for assessing body composition ratios in patients undergoing PD.

Impact of Visceral Fat Area Measured by Bioelectrical Impedance Analysis on Clinico-Pathologic Outcomes of Colorectal Surgery: Kyeong Eui Kim, Woo Jin Song, Minji Seok, Sung Uk Bae, Woon Kyung Jeong, Seong Kyu Baek; J Clin Nutr 2021;13(1):17-23. Published online June 30, 2021; DOI: https://doi.org/10.15747/jcn.2021.13.1.17

Abstract PDF: Purpose: This study investigated the relationship between the visceral fat area (VFA) and clinico-pathological outcomes in patients with colorectal cancer (CRC).
Methods: This retrospective study included 204 patients who underwent anthropometric measurement by bioelectrical impedance analysis (BIA) before surgical treatment for CRC between January 2016 and June 2020.
Results: According to the average value of the visceral fat area, 119 (58.3%) patients had a low visceral fat area, and 85 (59.1%) patients had a high visceral fat area. Patients with visceral obesity showed a higher BMI compared to patients without visceral obesity, (21.8±1.9 vs. 25.7±2.5, P<0.001). There was no significant difference in the overall perioperative outcomes including total operation time, time to gas out, sips of water, soft diet, hospital stay, and morbidity between patients in the low and high VFA groups. We divided patients into two subgroups according to the degree of cancer progression and more advanced cases with low VFA showed significantly more total and positive retrieved lymph nodes (LNs) (20.9±10.3 vs. 16.1±7.1, P=0.021 and 3.3±2.9 vs. 2.2±2.3, P=0.019, respectively) and a higher proportion of more than 12 retrieved LNs compared to patients with a high VFA (95.1% vs. 90.0%, P=0.047). Body composition analysis showed that phase angle, muscle composition, and body fluid composition were not statistically different between the two groups. However, body fat mass was statistically higher in the high VFA group (22.0±4.6 vs. 12.8±3.1, P<0.001).
Conclusion: Visceral obesity measured by BIA showed lower total and positive retrieved LNs and was not associated with adverse peri-operative outcomes, inflammatory and nutritional, and pathologic outcomes for CRC.

Clinical Application of Bioelectrical Impedance Analysis and its Phase Angle for Nutritional Assessment of Critically III Patients: Hyung-Sook Kim, Eun Sook Lee, Yeon Joo Lee, Jae Ho Lee, Choon-Taek Lee, Young-Jae Cho; J Clin Nutr 2015;7(2):54-61. Published online August 31, 2015; DOI: https://doi.org/10.15747/jcn.2015.7.2.54

Abstract PDF: Purpose:
Phase angle (PA) is objectively determined from resistance and reactance measured by bioelectrical impedance analysis (BIA)−a quick, noninvasive method. The aim of this study was to evaluate the clinical application of PA by BIA for nutritional assessment of critically ill patients.
Methods:
Eighty nine adult patients admitted to a medical intensive care unit (ICU) of a tertiary academic hospital from August 2012 to September 2013 were analyzed. PA values were measured by direct segmental multi-frequency BIA. As traditional nutrition assessment tools, body mass index (BMI), serum albumin levels, total lymphocyte counts, and our hospital’s nutrition screening index (NSI) were also recorded. Correlations between the results of BIA and other traditional parameters were analyzed.
Results:
PA showed correlation with traditional nutritional parameters, including BMI (r=0.479), serum albumin (r=0.347), and NSI score (r=0.483). Patients with PA lower than the median value (3.5°) had significantly lower nutritional status, increased duration of mechanical ventilation (P=0.039), and increased length of ICU stay (P=0.041).
Conclusion:
PA, as a reflection of body cell mass, measured by BIA could be a potentially useful parameter for nutritional assessment in critically ill patients.
