Modified endoscopic submucosal dissection with ligation for small tumors originated from gastric muscularis propria / 中华消化内镜杂志

ABSTRACT

Objective To explore the therapeutic value of modified endoscopic submucosal dissection with ligation (ESD-L) for small tumors originated from gastric muscularis propria.Methods Total of 60 patients with tumors originated from gastric muscularis propria,which was confirmed by endoscopic ultrasonography and smaller than 12 mm and were recruited to the present study.The conventional ESD technique was used to dissect the tumor to the depth of muscularis propria.Then the bottom of the tumor and the beneath muscularis propria were ligated fully with a nylon loop.Further dissection was applied till the whole tumor was isolated.Results All 60 lesions were dissected completely with perforation occurred in 10 cases,which were managed successfully with metal hemoclip.Pathologic diagnosis was obtained in all lesions,and no recurrence was found during the follow-up.Conclusion Modified technique of ESD-L is effective for complete resection of small tumors originated from gastric muscularis propria,which can also decrease the risk of stomach perforation.
