SUCCESSFUL RADIAL INCISION AND CUTTING FOR DISTAL STENOSIS DURING ESD OF THE ESOPHAGUS

Abstract

A 34-year-old woman underwent esophagogastroscopy to evaluate postoperative dysphagia. EGD revealed that the postoperative anastomotic site was stenotic, and a 15-mm flat lesion extending proximally just above the stenosis. ESD was performed; however, due to an anastomotic stenosis, the therapeutic scope could not be met. An incision on the anorectal side of the lesion was not possible. The radial incision and cutting technique selectively removes the scar tissue outside the lesion, thereby releasing the stenosis. The endoscope was passable, and allowed “en bloc” resection of the lesion.
