Nutritional status including changes of body composition is one of the most important clinical determinants of outcome after gastrectomy for gastric cancer. Various type of gastric operations are widely used with favorable outcome in South Korea. It was reported that several advantages of laparoscopic gastrectomy are the prevention of overt weight loss and enhanced recovery of muscle mass at 6 months after surgery. But there have been no longitudinal studies evaluating changes in the body composition according to the different type of anastomosis of laparoscopic gastrectomy. The purpose of this prospective study was to investigate changes in lipid indices associated with whole body composition during 1 year of follow-up after laparoscopic gastrectomy. Gastrectomy resulted in improved lipid indices and a reduction in body weight, fat and LBM. The HDL-Csignificantly increased in the non-obese group for 1 year after gastrectomy and the reduction of TG level was positively correlated with fat, especially with trunk fat.
