Successful endoscopic submucosal dissection for a tumor located completely within a colonic diverticulum after inversion of the diverticulum using a traction device
A 59-year-old man was diagnosed as having a flat-elevated tumor measuring 10 mm in diameter in the colon; the tumor was completely located within a colonic diverticulum in the hepatic flexure (Fig. 1A to C). Based on endoscopic evaluation, we determined there was a good chance of obtaining curative resection by endoscopic means. In addition, because we made it possible to invert the diverticulum into the colonic lumen by traction with forceps, we scheduled endoscopic submucosal dissection (ESD) using a traction device with the patient under general anesthesia (Fig. 1D).
