Abstract
We have previously reported on the usefulness of the endoscopic rnucosal resection in the stomach using a ligating device. Based on this experience, we tried to establish the safe and reliable technique of the mucosal resection, endoscopic mucosal Iigation (EML). We confirmed the usefulness of this technique and applied it clinically. 1 week after EML with submucosal injectian of physiological saline solusion, about 13mm in diameter of the mucosa fell out safely and correctly, while the surface of the proper muscular layer wask eptintact. 1 week after EML without submucosal injection, this procedure induced the dissection of submucasa and a part of proper muscular layer about 20mm in diameter. We performed this EML procedure in four patients. Follow-up endoscopic examination confirmed that gastric lesions were completely resected and not recured. It is concluded that EML procedure is easy and valuable treatment modality.
