Oncometabolic Surgery

Recently, the concept of "Onco-metabolic surgery" has emerged, and it is a theory that if anastomosis bypassing the duodenum and upper jejunum is performed after gastrectomy in gastric cancer patients with type 2 diabetes, diabetes can be expected to improve. The authors would like to compare and analyze the effect of long bowel Luwai gastrointestinal anastomosis in gastric cancer patients with type 2 diabetes in a multicenter prospective manner with that of type 2 diabetes gastric cancer patients who underwent a conventional Luwai gastrointestinal anastomosis.
