Sino-Russian Comparison of Outcomes After Proximal Gastrectomy With Double-Tract Reconstruction
Sponsor: The First Affiliated Hospital with Nanjing Medical University
Summary
This two-center retrospective observational cohort study compares Chinese and Russian patients who underwent curative proximal gastrectomy with double-tract reconstruction for proximal gastric adenocarcinoma or Siewert type II/III adenocarcinoma of the esophagogastric junction. The study evaluates postoperative reflux, nutritional status, perioperative outcomes, complications, and long-term survival. Propensity score matching will be used to improve comparability between the two cohorts.
