Bile Duct Injury During Laparoscopic Cholecystectomy: Has Anything Changed in 32 Years of Queensland Experience?

Background Bile duct injury (BDI) is a serious complication of laparoscopic cholecystectomy (LC). Large studies report an incidence of 0.08%-0.3%, but they also suggest that BDI in the LC era is more severe than in the era of open cholecystectomy. In light of our reported experience of managing BDI in 2002, this study aims to evaluate changes over the past two decades. Methods A single-center retrospective review for all patients referred to the hepatobiliary surgeons at the Princess Alexandra Hospital in Queensland, Australia for the management of BDI that occurred during LC from January 2001 to May 2022. This was compared to our historical data from 1990 to 2000 and statistically analyzed. Demographic characteristics, type of injury, intra-operative cholangiogram completion, attempted repair, the timing of referral to the tertiary center, and definite repair of BDI were analyzed. Results Sixty-five patients were referred to us with a similar severity of BDI to our previous study, but analysis showed an increase in intraoperative recognition of the injury to 74.4% (32 out of 43 patients). Additionally, the number of intra-operative cholangiograms performed increased dramatically to 66.2% (43 patients) which resulted in an increase in recognition of BDI. Conversion rate to open technique and attempted primary repair by operating surgeon decreased to 63% (27 patients) and 16% (11 patients), respectively, with referral time significantly shortened (P-value < 0.001). Conclusion The past two decades show an increased recognition of BDI, use of intra-operative cholangiogram, and decreased attempts to repair by the operating surgeon which can result in significant long-term complications. Instead, early recognition of BDI is critical for improved patient outcomes alongside expedited referral and appropriate surgical management by a hepatobiliary surgeon at a tertiary center.
