[ Summary ] |
Delayed complications such as bleeding and perforations can occur at the site of mucosal defects after endoscopic resection of colorectal tumors. To overcome these potential complications, a technique for complete closure of large mucosal defects is described. An endoloop/metallic clip method, which mimics surgical sutures, was developed for approximation of the borders and closure of large defects after endoscopic resection of colorectal tumors. The method can be performed with a single two-channel colonoscope by a single operator and can be used to close large defects immediately after endoscopic resection of colorectal tumors. We believe that closure of large mucosal defects by approximation of the mucosa promotes rapid wound healing and shields the submucosal vessels from mechanical trauma, thereby reducing the potential for delayed bleeding. |
