About this trial
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.

Trial outcomes
Primary outcomes
Incidence of postoperative reflux esophagitis
The diagnosis of reflux esophagitis was based on symptoms, endoscopic findings, and 24-hour esophageal pH monitoring.
Severity of reflux esophagitis
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).
Secondary outcomes
Postoperative nutritional recovery
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.
