Summary Biliary strictures after living donor liver transplantation (LDLT) with duct‐to‐duct (D‐D) reconstruction are associated with postoperative morbidity and mortality. The aims of this study were to evaluate the long‐term outcomes of endoscopic deployment of plastic stents, and to investigate factors associated with the stent deployment failure. Between April 2001 and May 2007, 96 patients received LDLT with D‐D reconstruction at Okayama University Hospital. Among them, 41 patients (43%) had anastomotic biliary strictures, and all were referred first for endoscopic retrograde cholangiography (ERC). When deployment was unsuccessful, a percutaneous transhepatic procedure was employed. Successful stent deployment was achieved in 35 out of total 41 patients (85%) by both procedures. Among the 35 patients, 28 had their stents removed as a result of strictures resolution. Eight patients underwent ERC and repeated stent deployment as a result of recurrence of the strictures. Finally, 21 out of 41 (51%) patients with biliary stricture were completely treated by endoscopic therapy during the observation period (median 873 days: range 77–2060). By multivariate analysis, biliary leakage was associated with stent deployment failure. Endoscopic deployment of plastic stents is a first‐line therapy for patients with biliary stricture after LDLT.

Difficult biliary cannulation was strongly associated with postoperative anatomic factors. In these situations, early introduction of NKPP should be recommended if the conventional biliary cannulation promises to be difficult.
