Key Points

This research examines how hospital volume influences the outcomes of esophagectomy and gastrectomy procedures.
Conducted a systematic review of existing studies on hospital volume and postoperative outcomes.
Performed a meta-analysis to quantitatively assess the relationship between hospital volume and surgical outcomes.
Analyzed mortality rates, complication rates, length of stay (LOS), and survival rates.
Higher hospital volume is linked to lower postoperative mortality rates.
Patients experience fewer complications in hospitals with greater surgical volume.
Average length of stay is shorter in high-volume hospitals.
Survival rates improve significantly at hospitals with higher volumes of esophagectomy and gastrectomy.

Abstract

Higher hospital volume is associated with lower mortality, reduced complications, shorter LOS, and improved survival. Identified thresholds exceed existing policy benchmarks, supporting further centralization of esophagogastric cancer surgery.
