Endoscopic submucosal dissection of gastric adenomas using the clutch cutter

Aim To evaluate the efficacy and safety of endoscopic submucosal dissection (ESD) using the clutch cutter (CC) (ESD-CC) for gastric adenoma (GA). Methods From June 2007 to August 2015, 122 consecutive patients with histological diagnoses of GA from specimens resected by ESD-CC were enrolled in this prospective study. The CC was used for all ESD steps (marking, mucosal incision, submucosal dissection, and hemostatic treatment), and its therapeutic efficacy and safety were assessed. Results Both the en-bloc resection rate and the R0 resection rate were 100% (122/122). The mean surgical time was 77.4 min, but the time varied significantly according to tumor size and location. No patients suffered perforation. Post-ESD-CC bleeding occurred in six cases (4.9%) that were successfully resolved by endoscopic hemostatic treatment. Conclusion ESD-CC is a technically efficient, safe, and easy method for resecting GA.
