Popis: Abstract Background Recent advances in esophageal cancer treatment require a reevaluation of the relationship between institutional case‐volume and patient outcome. The aim of this study was to analyze and update the association between surgical case‐volume and both in‐hospital and long‐term mortality after esophagectomy for esophageal cancer. Methods Data of all adult patients who received esophageal cancer surgery in Korea between 2004 and 2017 were extracted from the database of the National Health Insurance Service. Hospitals were categorized into three groups according to the average annual number of esophageal cancer surgery: low‐volume (48 cases/year). Postoperative in‐hospital and 1‐, 3‐, and 5‐year mortality were analyzed according to the categorized groups using logistic regression. Results In total, 11, 346 esophageal cancer surgeries in 122 hospitals were analyzed. In‐hospital mortality in the high‐, medium‐, and low‐volume centers were 3.4%, 6.4%, and 11.1%, respectively. In‐hospital mortality was significantly higher in low‐ volume (adjusted odds ratio, 3.91; confidence interval, 3.18–4.80; p
