Comparison of Double-tract and Tubular Gastric Anastomosis in Proximal Gastric Cancer
3. juni 2026 opdateret af: Qilu Hospital of Shandong University
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.
