For one-piece resection the conventional technique of endoscopic mucosal (EMR) is limited to gastric tumors 10 mm or less in size. In this retrospective study, we investigated efficacy and complications associated with a new EMR method, using an insulated-tip diathermic knife (IT-EMR).In total 41 patients were resected IT-EMR.One-piece rates 82% (14/17) for lesions less, 75% (12/16) those between 11 20 mm, 14% (1/7) over mm. Complication severe bleeding perforation 22% 5%, respectively. With median follow-up period 32 months, no recurrence was observed after these procedures.Compared EMR, method may have significant benefits, particularly regarding size, also lower rate.
