Abstract

Purpose: Laparoscopic sleeve gastrectomy (LSG) drastically affects body composition. However, studies focusing on the association between the changes in the pre-and postoperative muscle mass and postoperative results are limited. We evaluated the association between changes in the muscle mass and weight loss and fat reduction.

Methods: This retrospective study included 29 consecutive patients who underwent both LSG and a bioelectrical impedance analysis (BIA) consecutively. We investigated changes in the body composition on the BIA and visceral fat area (VFA) on computed tomography and correlational changes in muscle mass with weight loss and fat reduction.

Results: The total weight loss (%TWL) 12 months after surgery was 30.9%. The VFAs pre- and postoperatively were 224 and 71.0 cm², respectively. The fat mass (FM), percentage of FM, appendicular skeletal muscle mass (ASM), and skeletal muscle mass index (SMI) decreased from pre- to postoperatively (54.8 vs. 32.2 kg; 49.0 vs. 41.2%, 26.7 vs. 23.9 kg, 9.24 vs. 8.27, respectively), whereas the percentage of ASM (%ASM) increased (22.1 vs. 28.0%). The rate of change in %ASM positively correlated with weight loss and fat reduction (%TWL, rs = 0.65; %VFA loss, rs = 0.62).

Conclusion: The rate of change in %ASM was positively correlated with weight loss and fat reduction.

腹腔镜袖带胃切除术后阑尾骨骼肌质量变化与体重减轻和内脏脂肪减少的关系。

目的：腹腔镜袖带胃切除术（LSG）会严重影响身体成分。然而，针对术前和术后肌肉质量变化与术后效果之间关系的研究却很有限。我们评估了肌肉质量变化与体重减轻和脂肪减少之间的关系：这项回顾性研究包括 29 名连续接受 LSG 和生物电阻抗分析 (BIA) 的患者。我们调查了生物电阻抗分析和计算机断层扫描内脏脂肪面积（VFA）的身体成分变化，以及肌肉质量变化与体重减轻和脂肪减少的相关性：结果：术后12个月的总减重率（%TWL）为30.9%。术前和术后的 VFA 分别为 224 平方厘米和 71.0 平方厘米。术前和术后的脂肪量（FM）、脂肪量百分比、附着骨骼肌质量（ASM）和骨骼肌质量指数（SMI）分别为 54.8 对 32.2 千克、49.0 对 41.2%、26.7 对 23.9 千克、9.24 对 8.27），而附着骨骼肌百分比（%ASM）则有所增加（22.1 对 28.0%）。ASM%的变化率与体重减轻和脂肪减少呈正相关（%TWL，rs = 0.65；%VFA损失，rs = 0.62）：结论：ASM%的变化率与体重减轻和脂肪减少呈正相关。

期刊介绍： Surgery Today is the official journal of the Japan Surgical Society. The main purpose of the journal is to provide a place for the publication of high-quality papers documenting recent advances and new developments in all fields of surgery, both clinical and experimental. The journal welcomes original papers, review articles, and short communications, as well as short technical reports("How to do it"). The "How to do it" section will includes short articles on methods or techniques recommended for practical surgery. Papers submitted to the journal are reviewed by an international editorial board. Field of interest: All fields of surgery.
