Percutaneous biliary interventions are often performed for biliary obstruction when endoscopic stent placement is not feasible or has failed to provide relief. These secondary percutaneous interventions may be complicated by the presence of a previously placed occluded biliary stent requiring displacement and removal. The authors report a case of colonic perforation by a plastic biliary stent that was purposely displaced into the small bowel for passage at the time of percutaneous intervention and review the current practices concerning biliary stent removal in interventional radiology and gastrointestinal endoscopy.
当内镜下支架置入不可行或未能缓解症状时，常进行经皮胆道介入治疗以解除胆道梗阻。这些二次经皮介入治疗可能会因先前放置的闭塞性胆道支架需要移位和移除而变得复杂。作者报告了一例塑料胆道支架导致结肠穿孔的病例，该支架在经皮介入治疗时被有意移位至小肠以便通过，并回顾了介入放射学和胃肠内镜检查中有关胆道支架移除的当前做法。
