Proximal Gastrectomy Anterior Anastomosis With Pyloroplasty Versus Esophagogastric Anastomosis for Gastric Cancer

March 29, 2026 updated by: Yunhong Tian, Nanchong Central Hospital
This research is designed to compare proximal gastrectomy anterior anastomosis with pyloroplasty with esophagogastric anastomosis for gastric cancer. Gastroesophageal reflux disease, postoperative quality of life, short term outcomes, and long term outcomes will be compared.
