近年来,随着消化内镜诊断技术的发展,以及患者对恶性肿瘤“早查早治”意识的提高,越来越多的胃癌在无任何症状或仅有轻微症状的早期阶段即被发现。据报道,日本的早期胃癌发现率已达40%～50%。在日本.对于早期胃癌的治疗前几年普遍采用的方法是施行内镜下黏膜切除术(endoscopic mucosal resection,EMR)。EMR 有多种手术方式,如双腔内镜圈套法、透明帽吸引法等。近年来,随着新型内镜治疗用具的开发和治疗技术的进步,又出现了内镜粘膜下剥离术(endoscopic submucosal dissection,ESD),使得更多的早期胃癌病灶能够一次性地在内镜下切除。目前在
In recent years, with the development of digestive endoscopy diagnostic techniques and patients’ awareness of early detection and early diagnosis of malignant tumors, more and more gastric cancers have been found in the early stage without any symptoms or with mild symptoms. It is reported that Japan’s early detection rate of gastric cancer has reached 40% to 50%. In Japan, a common method used in the treatment of early gastric cancer a few years ago was endoscopic mucosal resection (EMR). EMR has a variety of surgical methods, such as double endoscopic traps, transparent cap to attract law. In recent years, with the development of new endoscopic treatment appliances and advances in therapeutic techniques, endoscopic submucosal dissection (ESD) has emerged that allows more early gastric lesions to be endoscopically resection. Now I am at
