Abstract

The water-jet hydro dissection technique has been shown to be effective for colorectal tumors. This case report illustrates type T hybrid knife for the elevation of the submucosal layer, cutting the mucosa and dissecting submucosal fibers. ESD was performed using ERBEJET 2 hydrodissection system and hybrid Knife. The resection was completed en bloc within 135 minutes without adverse events. Pathology examination revealed a well-differentiated adenocarcinoma confined to the shallow submucosal layer with free resection margins.
