[Use of vascular endostapler in surgery of the lower rectum].

A practical and effective method for rapid and bloodless preparation of the rectum using endovascular stapler devices during low anterior resection, or abdominal-perineal excision, is described. This method is presented as an effective means for easily dividing the anterior and lateral attachment of the rectum. The application of this technique is the absence of intraoperative bleeding related to injury of middle hemorrhoidal vessels, with minimal risk of autonomic pelvic nerve damage. An additional factor relevant in the choice of this technique, is the easier possibility to perform rectal dissection of an oncologically adequate tumor clearance from the margin of rectal tumor and with complete radical transection of the lateral ligaments fastly proceeding with the downward mobilization of the rectum close to the pelvic side walls, between the parietal and visceral layer of the pelvic fascia
