In the present review, we describe the current status of biliary stenting in patients with unresectable malignant biliary strictures. Self-expandable metallic stents (SEMS) are the ideal biliary stent for both distal and hilar biliary strictures, although in terms of distal biliary strictures, there is still some debate as to the selection of covered or uncovered SEMS, suprapapillary or transpapillary stent placement, side-by-side or stent-in-stent placement, unilateral or bilateral stent placement and the necessity for sphincterotomy. Further high-quality randomized controlled trials for these procedures are warranted.
在本综述中，我们描述了不可切除的恶性胆道狭窄患者胆道支架的现状。自膨式金属支架（SEMS）是远端和肝门部胆道狭窄的理想胆道支架，尽管在远端胆道狭窄方面，对于选择覆盖或不覆盖的 SEMS、胰管上或经胰管支架放置、并排或支架内支架放置、单侧或双侧支架放置以及是否需要括约肌切开术仍存在一些争议。需要进一步开展这些操作的高质量随机对照试验。
