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 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 316 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]. Univariate analysis revealed age (p- < 0.001), male gender (p- 0.004), morbid obesity (p- 0.001), and teaching hospital status (p-0.021) to be associated with CBD injury. Multivariate analysis revealed morbid obesity (2.8[2.1-4.3]; p-0.03) as the independent predictors for bile duct injury in patients undergoing cholecystectomy.
CONCLUSION
Our study finds a new association between obesity and bile duct injuries which has never been reported in literature before. The effect of obesity on outcomes in biliary surgery needs prospective evaluation.
