Risk Factors and Prognostic Significance of Severe Postoperative Complications After Curative Resection for Remnant Gastric Cancer: A Multicenter Retrospective Study.

ABSTRACT:

Background

Remnant gastric cancer (RGC) is associated with higher surgical difficulty and poorer long-term outcomes than primary gastric cancer. However, the impact of postoperative complications on prognosis in RGC remains unclear.

Methods

This retrospective, multicenter cohort study included 126 patients who underwent curative surgery for RGC across five institutions between 2007 and 2024. Postoperative complications were evaluated using the Clavien-Dindo (CD) classification. Patients were stratified into two groups based on the presence of severe complications (CD grade ≥ 3a). Logistic regression analysis was used to identify risk factors for complications, and Cox proportional hazards models were applied to determine prognostic factors for overall survival (OS) and recur
