上消化道内镜诊疗黏膜准备的现状及争议问题

我国是食管癌和胃癌的高发国家，但上消化道早期肿瘤的检出率较低。实现上消化道肿瘤早诊早治的关键，是高质量的上消化道内镜诊疗。但在内镜诊疗过程中，常因黏膜准备不充分导致疾病漏诊和误诊。目前，关于肠道准备方法，国内外已有多项指南进行规范，但上消化道黏膜准备方法尚无权威性指南规范。临床实践中，不同医疗机构采用的准备方法差别较大，黏膜准备效果有一定差异，在某些方面还存在较多争议。该文对国内外上消化道黏膜准备的现况和争议问题进行归纳总结，期望为临床规范的制订提供参考，同时，也有助于为后续相关课题研究提供思路。

Current situation and controversial issues of mucosal preparation for endoscopic diagnosis and treatment of upper gastrointestinal tract

China is a high incidence country of esophageal cancer and gastric cancer, but the detection rate of early upper gastrointestinal tumors is low. The key to early diagnosis and treatment of upper gastrointestinal tumors is high-quality endoscopic diagnosis and treatment of upper gastrointestinal tract. In the process of endoscopic diagnosis and treatment, inadequate mucosal preparation often leads to missed diagnosis and misdiagnosis. At present, there are many guidelines for intestinal preparation methods at home and abroad, but there is no authoritative guideline for upper gastrointestinal mucosal preparation methods. In clinical practice, the preparation methods adopted by different medical institutions are quite different, the mucosal preparation effect is different, and there are still many disputes in some aspects. This paper summarizes the current situation and controversial issues of upper gastrointestinal mucosal preparation at home and abroad, hopes to provide reference for the formulation of clinical norms, and also help to provide ideas for subsequent related research.
