Abstract:
ObjectiveTo evaluate a new coloanal anastomosis preserving dentate line and anal sphincter. Methods After total mesorectal excision in 87 patients with low rectal carcinoma, the rectum no more than 1cm above the dentate line was preserved. The rectal mucosa was stripped and the dentate line was saved, then a sustaining anastomotic tube was fixed into the proximal colon, and the colon was pulled down and anastomosed with the remnant rectum 0.5cm above the dentate line. Results The ultralow coloanal anastomosis with anal sphincter preservation was accomplished. No perioperative death and anastomotic leakage occurred. The patients were followed up for 2 to 6 months and the follow-up rate was 89%. There was no anastomotic recurrence. Soft tissue recurrence in pelvic cavity was found in 3 cases, lymph node recurrence in obturator space recurrence in 2 cases and liver metastasis in 6 cases. Anastomotic stenosis was found in 6 cases 12 months later. The defecation function returned to normal six months after operation. Conclusions The sustaining banding method in the ultralow coloanal anastomosis with anal sphincter preservation is a safe and reliable surgical procedure.
