Total rectal resection, colo-endoanal anastomosis and colic reservoir for cancer of the lower third of the rectum.
The treatment of low rectal cancer is still a widely debated topic in surgical oncology. From March 1990 to August 1991, 18 patients with tumors sited in the lower third of the rectum underwent a total rectal resection extended to the ano-rectal junction. As restorative procedure, a colic J-shaped pouch and a handsewn pouch-endoanal anastomosis was adopted. All the lesions were less than 8 cm from the anal verge; in 94.5% the distal tumor margin was located within 6.5 cm of the cutaneous edge. Histological clearance of the rectum cut edge was documented in all cases. Only one patient (Dukes C) relapsed four months later at the para-anastomotic level. No mortality or major complications related to surgical procedure were found. In 13 patients perfect continence was achieved and in 12 cases less than two bowel movements a day were recorded. No one complained of severe sexual dysfunction. All patients are still alive. The follow up ranged from 6 to 22 months (median: 12). This experience together with data obtained from last years' literature indicate that a conservative surgical procedure, as total rectal resection and colo-anal anastomosis, can be considered a feasible and radical option for treatment of low rectal cancer.
