Abstract

Background: Endoscopic treatment of anastomotic biliary stricture (ABS) after liver transplantation (LT) has been proven to be effective and safe, but long-term outcomes of early compared to late onset ABS have not been studied. The aim of this study is to compare the long-term outcome of early ABS to late ABS.

Methods: Of the 806 adult LT recipients (04/2006-12/2012), 93 patients met the criteria for inclusion, and were grouped into non-ABS (no stenosis on ERCP, n=41), early ABS (stenosis <90 days after LT, 18 [19.3%]), and late ABS (stenosis ≥90 days after LT, 34 [36.5%]). A propensity matched control group for the ABS group (n=42) was obtained matched for outcome variables for age, gender, and calculated MELD score at listing.

Results: Mean number of ERCPs (2.33±1.3 vs 2.56±1.5, P=.69) were comparable between the groups; however, significantly better long-term resolution of the stricture was noted in the early ABS group (94.44% vs 67.65%, P=.04). Kaplan-Meier analysis revealed worst survival in the early ABS group compared to the non-ABS, late ABS, and control groups (P=.0001).

Conclusion: LT recipients with early ABS have inferior graft survival despite better response to endoscopic intervention.
