Abstract：
Percutaneous endoscopic gastrostomy / jejunostomy (PEG/J) is a relatively safe and effective minimally invasive surgical approach to establish long-term enteral nutrition (EN) channels. Due to the good compliance and the reduced incidence of reflux and aspiration pneumonia, PEG/J is the preferred way for long-term EN and has been widely used in clinical applications. However, few technical guidelines or expert consensus guiding the clinical practice of PEG/J have been published. The formation of \"Chinese expert consensus on clinical application of percutaneous endoscopic gastrostomy / jejunostomy (2024 edition)\" is led by the Committee of Parenteral and Enteral Nutrition, Chinese Research Hospital Association. This consensus is based on the latest clinical evidence as well as the clinical experience of Chinese experts. This consensus is divided into PEG/J indications and contraindication, perioperative management, operational techniques, prevention, and treatment of related complications and other issues. All recommendations and their strengths were carried out by expert-voting method and presented as the basic framework of \"Recommended Opinions (level of evidence and strength of recommendation) and Summary of Evidence\". This consensus is registered on the International Practice Guide Registration Platform (IPGRP-2022CN329).
为建立长期的肠内营养支持治疗（EN）通道，经皮内镜下胃（空肠）造口术（PEG/J）提供了一种较为安全、有效的微创手术途径。PEG/J依从性好，且可降低反流和吸入性肺炎的发生率，是长期EN的首选方式，目前已得到了广泛的临床应用。但至今尚无相关的操作技术指南或专家共识，来指导临床规范开展这项技术。由中国研究型医院学会肠外肠内营养学专业委员会牵头，组织我国相关领域的专家学者，在国内外相关文献基础上，总结最新临床证据，结合中国专家临床经验，围绕PEG/J的适应证和禁忌证、围手术期管理、操作技术以及相关并发症防治等问题，按照“推荐意见（证据级别和推荐强度）和证据简述”的基本框架分别进行阐述，所有推荐意见及其推荐强度采用国际通用的专家投票方式进行，形成《中国经皮内镜下胃（空肠）造口术临床应用专家共识（2024版）》。本共识在国际实践指南注册平台完成注册申请（IPGRP-2022CN329）。.
