We read with great interest the recent endoscopy news reported by Bang et al ,1 discussing the lumen-apposing metal stents (LAMS) for pancreatic fluid collection (PFC) drainage. Patients with walled-off necrosis (WON) treated by using LAMS in their centre occurred a 50% (6/12) rate of adverse events including delayed bleeding (3/12), buried stent syndrome (2/12) and biliary stricture (1/12), which is higher than we expected on our experiences. As the authors reported all three patients presented with severe bleeding were confirmed with pseudoaneurysms. But another data from Sharaiha et al 2 showed that LAMS method was safe for PFC. In 124 patients with WON underwent endoscopic …

重新评估管腔对置金属支架（LAMS）在胰液收集引流中的作用

我们非常感兴趣地阅读了 Bang 等人最近报道的内窥镜新闻，1 讨论了用于胰液收集 (PFC) 引流的腔对置金属支架 (LAMS)。在其中心使用 LAMS 治疗的壁坏死 (WON) 患者发生 50% (6/12) 的不良事件，包括延迟出血 (3/12)、埋置支架综合征 (2/12) 和胆道狭窄。 1/12），高于我们的经验预期。正如作者报告的那样，所有三名出现严重出血的患者都被证实患有假性动脉瘤。但来自 Sharaiha 等人 2 的另一项数据表明，LAMS 方法对 PFC 是安全的。在 124 名 WON 患者中，接受了内镜检查……
