Introduction: Iatrogenic bile duct injury is a serious complication of cholecystectomy. The aim of this study was to assess predictors of bile duct injury using a national database. Methods: The Nationwide Inpatient Sample (2010-2012) was queried for laparoscopic cholecystectomy. We used a) diagnoses for bile duct injury and b) bile duct injury repair procedure codes as a surrogate marker for bile duct injuries. Results: A total of 1,015 patients had bile duct injury. The mean age was 58.2 ± 19.7 years, 53.5 % were males, and median Charlson co-morbidity score was 2 [2, 3]. Multivariate analysis revealed morbid obesity [2.8 (2.1-4.3); p = 0.03] and age >65 [1.5 (1.05-2.1); p = 0.01] as the independent predictors for bile duct injury in patients undergoing cholecystectomy. Conclusion: Our study finds a new association between obesity, aging, and bile duct injuries which has never been reported in literature before.
