Materials and Methods: In this retrospective, single-center study, clinical and procedural data of 36 patients who underwent percutaneous transhepatic retrieval of dysfunctional PBS between January 2015 and April 2021 were analyzed. Te primary outcomes were technical success, clinical success, complications, procedure time, and radiation exposure. Te secondary outcomes were biochemical indicators (total bilirubin [TB], direct bilirubin [DB], glutamic transaminase [ALT], and CA-19-9) measured before treatment and two weeks posttreatment.  \nResults: Technical and clinical success were both 100% . Minor complications occurred in 4 cases (11.2%), including 3 hemobilia (Grade 1) and 1 mild cholangitis (Grade 2) . Te mean procedure time was 39.22 ± 9.34 minutes, with no statistical signifcance between benign and malignant disease groups ([40.52 ± 9.0] min vs. [38.91 ± 9.5], p 􀂈 0.68) . Te mean radiation exposure was  \n326.13 ± 206.06 mGy, with no statistical signifcance between benign and malignant groups ([353.64 ± 258.93] mGy vs.[319.49 ± 196.15] mGy, p > 0.75) . Liver functions parameter improved signifcantly after 2 weeks (TB: [168.31 ± 53.07] vs.[41.70 ± 7.29] μmol/L, DB: [133.51 ± 46.42] vs. [25.39 ± 7.26] μmol/L, ALT: [94.67 ± 38.06] vs. [47.41 ± 13.69] U/L, and CA-19-9:[479 .11 ± 160. 14] vs. [150 .72 ± 105.72] U/mL) (all p 􀂈 0.01) .  \nConclusion: Tis study suggests that percutaneous transhepatic retrieval of dysfunctional PBS appears to be a safe and efective alternative when ERCP is not feasible. However, given the retrospective single-center design, limited sample size, and short followup, larger multicenter studies with longer observation are needed to validate these fndings.  \nKeywords: bile duct obstruction; cholangiography; cholangiopancreatography; endoscopic retrograde; stents  \n1. Introduction  \nBiliary stents are commonly used to facilitate bile drainage into the digestive tract. Tey are frequently employed for the palliation of malignant biliary obstruction and in the management of benign conditions, including biliary fstulas, benign biliary strictures, and iatrogenic bile duct lesions resulting from laparoscopic cholecystectomy [1, 2]. In these patients,  \ninterventional radiologists often weigh the decision between placing either a plastic biliary stent (PBS) or a self-expandable metallic stent (SEMS) [3]. Te decision generally depends on expertise, resources, the cost of the stent, the type of disease, and the patient’s life expectancy [4]. Te patency of PBS is limited, with a median of 35–165 days, and stent dysfunction can occur, leading to complications such as cholangitis or infection [4, 5].
