A new endoscopic submucosal resection -ligation technique for gastric tumors.

Although most subepithelial lesions are benign, the malignant forms could present as serious life-threating cancers. Their accurate diagnosis depends on complete surgical resection. Different endoscopic methods have been recommended for the resection. Recently, the EMR has been considered as a safe and effective technique, while various revised EMR techniques have been introduced. In this study, a new version of EMR has been evaluated in two patients. Two middle-aged cases with gastric subepithelial tumors were admitted to Taleghani gastrointestinal department. The polyps were resected via our new Endoscopic Mucosal Resection (EMR) technique. In this technique, the needle knife was used for un-roofing the mucosal surface. Then, the polyps were resected with hot snares. The hemoclips were applied for ligation too. We found no early or delayed complications. Furthermore, the microscopic margins of the lesions were free. Our study represented a safe and cost-beneficial technique for subepithelial lesions and no complications was found and the margins were free. However, further investigations are required for confirming the validity of this new EMR technique. ©2020 RIGLD, Research Institute for Gastroenterology and Liver Diseases.
