BACKGROUND: The aims of this study were to characterize the features of the biliary strictures that occur after duct-to-duct biliary reconstruction during right-lobe living-donor liver transplantation (LDLT) and to evaluate the feasibility of correcting such stricture endoscopically by inserting an "inside stent," that is, a short internal stent, above the sphincter of Oddi. METHODS: Biliary stricture occurred in 26 (35.6%) of 73 consecutive patients who underwent right-lobe LDLT with duct-to-duct biliary reconstruction from July 1999 through October 2001 and survived for more than 3 months. Of the 26 patients who had biliary stricture, 22 were referred for endoscopic retrograde cholangiography (ERC) and 4 for percutaneous cholangiography. RESULTS: ERC disclosed biliary stricture in 19 (86.4%) of the 22 patients who underwent the procedure. One patient had an unbranched stricture, 16 had a fork-shaped stricture, 1 had a trident-shaped stricture, and 1 had a stricture with more than three branches. Fourteen (73.7%) of the patients with strictures were treated endoscopically by inserting inside stents ranging from 7 F to 12 F in size, three underwent a Roux-en-Y hepaticojejunostomy to repair their stricture, and two were closely observed as outpatients. Of the 14 patients who were treated with the inside-stent, only 1 had acute cholangitis immediately after the procedure and underwent a Roux-en-Y hepaticojejunostomy. The other 13 patients who were treated with the inside stent have not required surgical repair for as long as an average of 586 days. CONCLUSION: Endoscopic placement of an inside stent is useful for treating biliary strictures in patients who have undergone right-lobe LDLT with duct-to-duct reconstruction.
