摘要
Endoscopic mucosal resection is indicated in limited esophageal carcinomas with in?ltration of the mucosa. As submucosal cancer is combined with a rate of lymph node metastasis in up to 30% mucosectomy is not the procedure of choice. The main techniques of endoscopic mucosal resection are the “suck and cut” technique using a cap on the endoscope or a ligation device to create a pseudocroup of the carcinoma. Submucosal injection of saline or other solutions is recommended prior to diathermic mucosectomy in order to reduce the risk of perforation or haemorrhage. The long term results of endoscopic mucosal resection show tumor speci?c 5 year survival rates of about 97% especially if the indication is restricted to m1 and m2 mucosal carcinomas.
