Comparison of Gastroesophageal Reflux and Quality of Life Between Double-tract and Tubular Gastric Anastomosis in Proximal Gastric Cancer Patients
This study includes patients diagnosed with proximal gastric cancer (Siewert type II/III, cT1-3N0-1M0) across six tertiary hospitals, who underwent either double-tract reconstruction (DTR) or tubular gastric anastomosis (TGA). Participants were divided into two groups based on the surgical procedure. We conducted a comparative analysis of postoperative outcomes by evaluating electronic medical records, postoperative gastroscopy, 24-hour esophageal pH monitoring, and relevant rating scales.
• Pathologically confirmed gastric adenocarcinoma by biopsy
• Carcinoma of the upper gastric body or Siewert type II/III adenocarcinoma of the esophagogastric junction (AEG), with a clinical stage of cT1-3N0-1M0
• Age 18-75 years, with a performance status (PS) score of 0-2
• Candidates for planned surgical resection, eligible for either double-tract reconstruction or tubular gastric anastomosis based on preoperative assessment
• No severe dysfunction of vital organs (liver, kidney, heart, lung, or brain), and no severe infection or uncontrolled chronic diseases
