Abstract: Background/aim: To evaluate the safety and outcomes of percutaneous transhepatic management of dysfunctioning plastic biliary endoprostheses (PBE) in patients with benign/malign biliary strictures. Materials and methods: Twenty-nine patients (22 men, 7 women; mean age of 60.7 (range 33-88) years) diagnosed with dysfunctioning PBE were included. Percutaneous transhepatic biliary drainage and subsequent PBE dislodgment into the bowel were performed in all cases. Patient demographics, etiology of the biliary stricture, indication, technical success, complications, and clinical outcomes were gleaned from medical records. Results: Seventeen patients had malignant strictures, while 12 patients had benign conditions. A total of 36 PBE (33 straight, 3 double-J) were treated. Six patients had more than one PBE. Successful dislodgement of the PBE was achieved in 28 (96.6%) of the cases. Monorail threading was performed in 8 cases while dislodgement by balloon friction was utilized in 21 patients. There was no statistical significance between benign and malignant biliary strictures regarding dislodgement duration (p = 0.080). No major complication was encountered. Thirteen minor complications in 10 patients including abdominal pain (n = 8) and mild hemobilia (n = 5) were observed and treated conservatively. Uneventful passage of the PBE was reported by all patients with technical success. Conclusion: Percutaneous transhepatic methods aid as a reasonable alternative in the treatment of benign and malignant biliary strictures in patients with dysfunctioning PBE when endoscopic approaches fail or are not eligible.
