ObjectiveThe centralization of complex surgical procedures is associated with better postoperative outcomes. However, little is known about the impact of hospital volume on the outcome after distal pancreatectomy.MethodsUsing the French national hospital discharge database, we identified all patients having undergone distal pancreatectomy in France between 2012 and 2015. A spline model was applied to determine the caseload cut-off in annual distal pancreatectomy that influenced 90-day postoperative mortality.ResultsA total of 3314 patients were identified. Use of a spline model did not reveal a cut-off in the annual distal pancreatectomy caseload. By taking the median number of distal pancreatectomy (n = 5) and the third quartile (n = 15), we stratified centers into low, intermediate, and high hospital volume groups. The overall postoperative mortality rate was 3.0% and did not differ significantly between these groups. In a multivariable analysis, age, Charlson comorbidity score, septic complications, hemorrhage, shock, and reoperation were independently associated with a greater overall risk of death. However, hospital volume had no impact on mortality after distal pancreatectomy (odds ratio, 0.954; 95% confidence interval, 0.552-1.651, P = 0.867).ConclusionsHospital volume does not seem to influence mortality after distal pancreatectomy in France, and centralization may not necessarily improve outcomes.
