Through the tunnel, endoscopic diagnosis or treatment is performed for lesions in the mucosa, in the MP, and even outside the gastrointestinal(GI) tract.At present, the tunnel technique application range covers the following:(1)Treatment of lesions originating from the mucosal layer, e.g., endoscopic submucosal tunnel dissection for oesophageal large or circular early-stage cancer or precancerosis;(2) treatment of lesions from the MP layer, per-oral endoscopic myotomy, submucosal tunnelling endoscopic resection, etc.; and(3) diagnosis and treatment of lesions outside the GI tract, such as resection of lymph nodes and benign tumour excision in the mediastinum or abdominal cavity. With the increasing number of DETTs performed worldwide, endoscopic tunnel therapeutics, which is based on DETT, has been gradually developed and optimized. However, there is not yet an expert consensus on DETT to regulate its indications, contraindications, surgical procedure, and postoperative treatment.The International DETT Alliance signed up this consensus to standardize the procedures of DETT. In this consensus, we describe the definition, mechanism,and significance of DETT, prevention of infection and concepts of DETTassociated complications, methods to establish a submucosal tunnel, and application of DETT for lesions in the mucosa, in the MP and outside the GI tract(indications and contraindications, procedures, pre-and postoperative treatments, effectiveness, complications and treatments, and a comparison between DETT and other operations).展开更多

文摘背景近年来随着人们生活及饮食习惯的改变,反流性食管炎(reflux esophagitis,RE)的发病率逐年上升,影响了人们的生活质量.同时RE发病的相关危险因素及幽门螺杆菌(Helicobacter pylori,H.pylori)的感染与根除同RE的关系是当下的热点问题.目的通过临床大数据分析探究RE发病的相关危险因素及与H.pylori感染的关系.方法采用回顾性分析,对2010-03/2018-12在朝阳医院行消化内镜检查的住院患者进行筛选及分组研究.病例组为消化内镜确诊为RE,并且有明确洛杉矶(LosAngeles,LA)分级结果及H.pylori检查结果的住院患者,并进一步将病例组分为轻度RE组(LA-A)和重度RE组(LA-B、LA-C和LA-D);对照组是通过消化内镜检查确认为非RE、有H.pylori检查结果,并且排除了胃食管反流症状的患者.通过大数据平台,分析性别、年龄、体质指数(body mass index,BMI)、血脂、血糖、吸烟饮酒史、基础病、食管裂孔疝和H.pylori感染等多种因素同RE的关系.结果单因素Logistic回归分析发现对于RE,男性、BMI、吸烟史、食管裂孔疝是其危险因素,高密度脂蛋白胆固醇为其保护因素,而高血压和高脂血症病史是重度RE的危险因素,甘油三脂升高是轻度RE的危险因素.多因素Logistic回归校正后显示,无论病情程度如何,男性、BMI和食管裂孔疝均是RE的独立危险因素,H.pylori感染是RE的保护因素.结论RE的发病和发展与生活习惯、基础疾病和H.pylori感染等密切相关.
