内镜下黏膜切除术(EMR)是将病灶完整的切除,其切除标本可以进行完整组织学检查。胃壁主要由黏膜层和固有肌层两个主要部分构成,两者之间由黏膜下层的疏松结缔组织连接,并可以在外力作用下轻易分离。这是仅切除黏膜层,而肌层不受损伤的组织解剖学基础。1历史背景早期胃癌的概念
Endoscopic mucosal resection (EMR) is the complete removal of the lesion, the resection of the specimen for complete histological examination. The stomach wall consists mainly of the mucosal and muscularis propria, which are connected by the loose connective tissue of the submucosa and easily detached by external forces. This is the anatomy of the tissue where only the mucosa is excised and the muscularis is intact. 1 History Background Concept of early gastric cancer
