Predictors of Failed Transcystic Laparoscopic Common Bile Duct Exploration: Analysis of Multicenter Integrated Health System Database.

Background: The aim of this study is to report our experience with laparoscopic common bile duct exploration (LCBDE) and validate the experts' opinion about anatomical predictors of failed transcystic LCBDE (TLCBDE) approach.

Methods: Patients undergoing LCBDE at Kaiser Permanente Southern California hospitals (2005-2015) were included. Predictors of failed TLCBDE were identified using bivariate analysis.

Results: Of 115 LCBDE, 89.6% were TLCBDE and 10.4% through choledochotomy. Success rate, morbidity, and length of hospital stay were 83.5%, 6.1%, and 3.8 days respectively. Only stone size:cystic duct ratio >1 (35% versus 63%, P = .044) was associated with failure of TLCBDE. In accordance with experts' opinion, there was a suggestive association of stone size ≥6 mm, cystic duct ≤4 mm, multiple stones, and proximal stone location with failure; however, these did not reach statistical significance.

Conclusion: LCBDE is an effective and safe mean of clearing common bile duct stones at community hospitals of an integrated health system. Previously cited contraindications for TLCBDE are not absolute, but rather predictors of failure.
