Predictors of technical success of percutaneous transhepatic common bile duct stone removal: is it only a matter of stone size?

ConclusionsPTSR is effective for CBD stone removal in older adults and individuals with altered gastrointestinal tract anatomy. The aforementioned risk factors for technical failure should be considered in preoperative evaluation before PTSR to improve the success rate.Key Points•PTSR is effective in symptomatic CBD stone management among older adults and individuals with altered anatomy. Investigating clinical /anatomic factors can guide radiologists toward a more comprehensive preoperative evaluation to maximize the success rate.•Our data indicate that dilated CBD (diameter  ≥ 15.5 mm) and left-sided PTBDs reduce the technical success rate by 506-fold and 22-fold, respectively.•Clinical factors such as previous failed ERCP for stone removal and higher severity of acute cholangitis lessen the technical success rate.
