title: Endoscopic management of biliary strictures after duct-to-duct biliary reconstruction in right-lobe living-donor liver transplantation.
abstract: 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.
  
  
  CONCLUSIONS
  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.
