早期胃癌(early gastric carcinoma,ECG)是指无论有无淋巴结转移,癌组织局限于黏膜或黏膜下层者。治疗早期胃癌传统的方法是外科根治切除术,手术切除病变以后5年存活率可达90%以上。但外科手术由于破坏了胃的正常解剖结构,其生理功能受到很大影响,且创伤大,并发症多,恢复慢,费用高。近年,由于内镜治疗技术的进步和治疗器械的不断开发和应用,EGC的内镜下治疗成为可能。EGC内镜下治疗主要有两种方法:内镜黏膜
Early gastric cancer (early gastric carcinoma, ECG) is with or without lymph node metastasis, cancer confined to the mucosa or submucosa. The traditional treatment of early gastric cancer is a radical surgical resection, surgical excision of the 5-year survival rate of up to 90%. However, due to the destruction of the normal anatomy of the stomach surgery, its physiological function has been greatly affected, and trauma, complications, slow recovery, high cost. In recent years, due to the progress of endoscopic treatment technology and the continuous development and application of therapeutic devices, endoscopic treatment of EGC is possible. EGC endoscopic treatment there are two main ways: endoscopic mucosa
