Abstract
Background:
In cases of endoscopic intervention treatment for biliary stricture which fail, a percutaneous approach can be subsequently attempted. However, the quality of life is lower for those patients with percutaneous transhepatic biliary drainage (PTBD) tubes than those with endoscopic retrograde biliary drainage tubes. In this study, we report the outcome of the application of percutaneous transhepatic biliary stenting (PTBS) for use in subsequent endoscopic treatment of biliary stricture after living donor liver transplantation (LDLT).
Methods:
Of 165 patients who underwent LDLT, 40 (24.2%) were diagnosed with anastomotic biliary strictures. Of these patients, seven agreed to treatment using PTBS using a plastic stent with endoscopic follow-up instead of treatment by insertion of a PTBD tube, and were enrolled in this study.
Results:
In all seven patients, the use of this technique enabled effective advancement of a guide wire and successful placement of one or two plastic stents (7 or 10 Fr) into the PTBD tract. There were no PTBS-related complications associated with the procedure. The median duration for stent use was 40.3 weeks (range; 27.6~65.0). Upon final removal of all stents, the stricture had been resolved in four (57%) of the seven patients.
