Comparison of Double-tract and Tubular Gastric Anastomosis in Proximal Gastric Cancer

June 3, 2026 updated by: 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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Incidence of postoperative reflux esophagitis
Time Frame: 6 month after surgery
The diagnosis of reflux esophagitis was based on symptoms, endoscopic findings, and 24-hour esophageal pH monitoring.
6 month after surgery
Severity of reflux esophagitis
Time Frame: 6 month after surgery
According to the diagnostic and grading criteria for reflux esophagitis, patients were classified into four categories: no reflux esophagitis, mild (LA-A/B), moderate (LA-C), and severe (LA-D).
6 month after surgery

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Postoperative nutritional recovery
Time Frame: 1 year after surgery
The body weight change rate at different postoperative time points compared with preoperative levels, along with albumin, prealbumin, and hemoglobin levels, were comprehensively considered in the assessment of postoperative nutritional status.
1 year after surgery
