Objectives Interventional endoscopic ultrasonography (EUS) procedures are gaining popularity and the most commonly performed procedures include EUS-guided drainage of pancreatic pseudocyst, EUS-guided biliary drainage, EUS-guided pancreatic duct drainage and EUS-guided celiac plexus ablation. The aim of this paper is to formulate a set of practice guidelines addressing various aspects of the above procedures. Methods Formulation of the guidelines was based on the best scientific evidence available. The RAND/UCLA appropriateness methodology (RAM) was used. Panellists recruited comprised experts in surgery, interventional EUS, interventional radiology and oncology from 11 countries. Between June 2014 and October 2016, the panellists met in meetings to discuss and vote on the clinical scenarios for each of the interventional EUS procedures in question. Results A total of 15 statements on EUS-guided drainage of pancreatic pseudocyst, 15 statements on EUS-guided biliary drainage, 12 statements on EUS-guided pancreatic duct drainage and 14 statements on EUS-guided celiac plexus ablation were formulated. The statements addressed the indications for the procedures, technical aspects, pre- and post-procedural management, management of complications, and competency and training in the procedures. All statements except one were found to be appropriate. Randomised studies to address clinical questions in a number of aspects of the procedures are urgently required. Conclusions The current guidelines on interventional EUS procedures are the first published by an endoscopic society. These guidelines provide an in-depth review of the current evidence and standardise the management of the procedures.

关于介入性 EUS 程序最佳管理的共识指南：来自亚洲 EUS 小组 RAND/UCLA 专家小组的结果

目的 介入性内镜超声 (EUS) 手术越来越受欢迎，最常用的手术包括 EUS 引导的胰腺假性囊肿引流、EUS 引导的胆道引流、EUS 引导的胰管引流和 EUS 引导的腹腔神经丛消融术。本文的目的是制定一套实践指南，解决上述程序的各个方面。方法 指南的制定基于现有的最佳科学证据。使用了 RAND/UCLA 适当性方法 (RAM)。招募的小组成员包括来自 11 个国家的外科、介入性 EUS、介入放射学和肿瘤学专家。2014 年 6 月至 2016 年 10 月期间，小组成员在会议上开会讨论和投票表决每个介入性 EUS 程序的临床情况。结果共制定EUS引导下胰腺假性囊肿引流15篇、EUS引导胆道引流15篇、EUS引导胰管引流12篇、EUS引导腹腔神经丛消融14篇。这些声明涉及程序的适应症、技术方面、程序前后管理、并发症管理以及程序中的能力和培训。除一项外，所有陈述都被认为是合适的。迫切需要随机研究来解决程序的许多方面的临床问题。结论 目前关于介入性 EUS 程序的指南是内窥镜协会首次发布的。这些指南对当前证据进行了深入审查，并规范了程序的管理。
