Stent migration and sludge clogging are characteristic problems in biliary covered self‐expandable metal stent (SEMS) placement. Intraductal placement without endoscopic sphincterotomy (ES) may help reduce their occurrence. We examined the feasibility of intraductal placement of a covered SEMS with a long string without ES in patients with unresectable distal malignant biliary obstruction (MBO).

导管内置入长绳全覆盖金属支架治疗远端恶性胆道梗阻无需内镜括约肌切开术：一项前瞻性多中心可行性研究

支架迁移和淤泥堵塞是胆道覆盖的自膨胀金属支架 (SEMS) 放置的特征性问题。没有内窥镜括约肌切开术 (ES) 的导管内放置可能有助于减少它们的发生。我们研究了在不可切除的远端恶性胆道梗阻 (MBO) 患者中导管内放置带长绳的无 ES 覆盖的 SEMS 的可行性。
