Postoperative surgical complications are a major risk factor for changes in body weight and body composition after gastrectomy. However, the influence of postoperative surgical complications after gastrectomy on body weight and body composition changes remains unclear. Patients and Methods: This retrospective study examined patients who underwent curative surgery for gastric cancer between May 2010 and February 2017. Their body weight and composition were evaluated by a bioelectrical impedance analyzer within 1 week before surgery, and at 1 week, 1 month and 3 months after surgery. Patients were classified as those with surgical complications and those without. Results: Eight hundred and eighty-eight patients (156 in the group with complications and 732 in the group without) were entered in the present study. When comparing the two groups, the patients' background and surgical factors significantly differed, while the pathological findings were similar. The body weight losses at 1 week, 1 month, and 3 months after surgery were 3.8%, 7.0%, and 10.4%, respectively, in those with complications, and 3.3%, 5.6%, and 6.8%, respectively, in the group without, with p-values of 0.001, 0.002, and 0.001, respectively. The corresponding lean body mass losses were 3.7%, 6.5%, and 6.8%, and 3.2%, 4.2%, and 3.5%, respectively, with p-values of 0.001, 0.001, and 0.001, respectively. Conclusion: Decreases in body weight and lean body mass after gastrectomy were more serious in the patients with surgical complications than in those without. To maintain body weight and lean body mass in patients with surgical complications, additional care or treatments are needed. ER -
