💬In plain words
What the trial is, and whether it could suit you
This prospective, single-center, randomized, controlled, non-inferiority clinical trial aims to compare the safety and postoperative quality of life of early upper gastric cancer patients undergoing total laparoscopic proximal gastrectomy (TLPG) with preservation of both the hepatic and celiac branches of the vagus nerve versus preservation of the hepatic branch only. The primary endpoint is gastric emptying half-time of solid food at 6 months after surgery. Secondary outcomes include incidence of reflux esophagitis, quality of life scores (EORTC QLQ-C30/STO22), number and positivity rate of lymph nodes retrieved, and 3-year disease-free survival. The study will provide evidence for optimizing minimally invasive surgical strategies for early upper gastric cancer.
