Body composition changes after gastrectomy for gastric cancer

Abstract

Rationale: Body weight loss is a common problem after gastrectomy, and body composition changes are substantially affected by gastrectomy. The purpose of this study was to evaluate body composition changes of patients who underwent gastrectomy for gastric cancer

Methods: We retrospectively collected and reviewed patients’ data who underwent radical gastrectomy for gastric cancer between December 2015 and December 2016. Body composition was examined by segmental multifrequency bioelectrical impedance analysis. All measurements were obtained preoperatively and 1, 3, 6, 9, and 12 months after surgery

Results: A total of 91 patients were included for analysis. Distal gastrectomy and total gastrectomy were performed 68 and 23 patients, respectively. Body weight loss at 1, 3, 6, 9, and 12 months was 3.2kg (4.9%), 5.0kg (7.6%), 5.5kg (8.3%), 5.6kg (8.3%), and 5.6kg (8.3%), respectively. Loss of fat mass was greater than loss of lean body mass (4.2kg vs. 0.8kg). Loss of lean body mass was There were no significant differences between distal gastrectomy and total gastrectomy, but loss of lean body mass at 3 months after surgery was significantly greater in total gastrectomy than distal gastrectomy (p=0.005). There were no significant differences between partial omentectomy and total omentectomy.

Conclusions: Body weight loss occurred during the first 6 months after surgery. Especially, loss of fat mass accounted for a significant part of body weight loss after gastrectomy. Loss of lean body mass was significantly greater in total gastrectomy than distal gastrectomy
