Outcomes of management for biliary stricture after living donor liver transplantation with hepaticojejunostomy using short-type double-balloon enteroscopy.

ABSTRACT

BACKGROUND AND AIMS: To evaluate the outcomes of management for biliary stricture (BS) after living donor liver transplantation (LDLT) using short-type double-balloon enteroscopy. METHODS: This study retrospectively evaluated 20 patients who underwent endoscopic retrograde cholangiography using short-type double-balloon enteroscopy (sDB-ERC) upon suspicion of BS after LDLT with hepaticojejunal (HJ) reconstruction at Okayama University Hospital. RESULTS: Scope insertion to the HJ site and sDB-ERC succeeded in 85 % (17/20) and 82.4 % (14/17) of patients, respectively. Of 14 patients who required treatment for BS, 11 were successfully treated using sDB-ERC, and 3 were successfully treated using sDB-ERC and rendezvous procedures. Adverse events occurred in 2.9 % of all sessions (2/68). After resolution of BS, 7 patients (50 %) experienced a recurrence. Of these, 6 (85.7 %) were treated with only balloon dilation, and 1 (14.3 %) was treated with both balloon dilation and stent deployment (P = 0.029). CONCLUSIONS: sDB-ERC is a useful procedure for diagnosis and treatment for BS after LDLT with HJ reconstruction. Balloon dilation combined with stent deployment might be recommended for definite resolution of BS.
