Comparison between laparoscopic pylorus-preserving gastrectomy and laparoscopic distal gastrectomy for overweight patients with early gastric cancer.

LPPG and LDG groups showed similar weight loss. However, the LPPG group had higher albumin and protein levels than the LDG group of overweight patients. Thus, it is not necessary to select LDG only for weight loss. LPPG may be selected as one option due to its potential nutritional benefit when pyloric stenosis is properly managed.
