Liver transplantation for iatrogenic bile duct injury: a systematic review.

ABSTRACT

BACKGROUND: Bile duct injury (BDI) is an infrequent but serious complication of cholecystectomy, often with life-changing consequences. Liver transplantation (LT) may be required following severe BDI, however given the rarity, few large studies exist to guide management for complex BDI. METHODS: A systematic review was performed to assess post-operative complications, 30-day mortality, retransplant rate and 1-year and 5-year survival following LT for BDI in Medline, EMBASE, Web of Science or Cochrane Clinical Trials Database. RESULTS: Seven articles met inclusion criteria, describing 179 patients that underwent LT for BDI. Secondary biliary cirrhosis (SBC) was the main indication for LT (82.2% of patients). Median model for end-stage liver disease (MELD) scores at time of LT ranged from 16 to 20.5. Median 30-day mortality was 20.0%. The 1-year and 5-year survival ranges were 55.0-84.3% and 30.0-83.3% respectively, and the overall retransplant rate was 11.5%. CONCLUSION: BDI is rarely indicated for LT, predominantly for SBC following multiple prior interventions. MELD scores poorly reflect underlying morbidity, and exception criteria for waitlisting may avoid prolonged LT waiting times. 30-day mortality was higher than for non-BDI indications, with comparable long term survival, suggesting that LT remains a viable but high risk salvage option for severe BDI.
