Published 2014 · Medicine
Abstract Aim To evaluate the long-term outcomes of a percutaneous transhepatic cholangioplasty in benign biliary stricture. Materials and methods Between May 2008 and May 2010, the efficacy of this percutaneous transhepatic cholangioplasty was studied in 14 patients with benign biliary strictures. The main purpose of the study was to dilate the stricture by balloon and perform internal/external drainage for 6–9 months. The follow-up period ranged from 3 to 61 months (mean, 34.4 months), and outcomes were classified according to the patient's clinical symptoms, laboratory parameters and the need for further interventions. Results The long-term success was achieved in 13 patients. Four patients showed signs of restenosis on follow-up. Primary success rate was 62.4% and secondary success rate was 92.8%. Conclusions Percutaneous transhepatic cholangioplasty of benign biliary strictures with extended internal–external drainage has good long-term results. Advantages over surgery are its minimal invasiveness and reduced risk of complications.
