Abstract

Background: The optimal endoscopic protocol for treating postorthotopic liver transplantation (OLT) anastomotic biliary strictures (ABSs) has not been established. Objective: To review the technique and outcomes of endoscopic retrograde cholangiopancreatography (ERCP) with maximal stenting for post-OLT ABSs at our institution. Design: Retrospective study. Setting: Tertiary-care center. Patients: Eighty-three patients with a diagnosis of ABS. Interventions: ERCP with balloon dilation and maximal stenting. Main Outcome Measurements: Stricture resolution, stricture recurrence, and complication rates. Results: Of 83 patients, 69 completed treatment, of whom 65 (94%) achieved resolution and 4 (6%) required hepaticojejunostomy (HJ). The remaining 14 patients who did not achieve a study endpoint were excluded (9 deaths or redo OLT unrelated to biliary disease, and 5 without follow-up). Comparing the resolution group and the HJ group, there were, respectively, 8.0 and 3.5 total stents (P = .021), 2.5 and 1.3 stents per ERCP (P = .018) (maximum = 9), 4.2 and 2.8 ERCPs (P = .15), and 20 and 22 months from OLT to ABS diagnosis (P = .19). There were 2 cases of ERCP pancreatitis (0.7%) and 2 cases of periprocedural bacteremia of 286 total ERCPs and no episodes of cholangitis caused by stent occlusion. In a median follow-up of 11 months (range 0-39), 2 (3%) patients had ABS recurrence that was successfully re-treated with ERCP. A multivariate Cox model demonstrated that treatment success was directly related to the number of stents used in total and per ERCP. Limitations: Retrospective study, single endoscopist. Conclusions: Our maximal stenting protocol for ABSs is effective, safe, rarely associated with ABS recurrence, and conducive to less frequent stent exchange and therefore fewer ERCPs compared with conventional treatment.
