Antireflux Covered Metal Stent for Nonresectable Distal Malignant Biliary Obstruction: Multicenter Randomized Controlled Trial
Digestive endoscopy(2019)
摘要
An antireflux metal stent (ARMS) for nonresectable distal malignant biliary obstruction (MBO) may prevent recurrent biliary obstruction (RBO) as a result of duodenobiliary reflux and prolong time to RBO (TRBO). Superiority of ARMS over conventional covered self‐expandable metal stents (SEMS) has not been fully examined.
