Coloanal anastomosis after resection of low rectal cancer in the elderly.
Twenty-two patients had coloanal anastomoses performed after resection of low rectal tumors (16 adenocarcinomas and 6 large degenerated villous adenomas). The patients had an average age of 72 years (range: 62-85). A hand-sewn anastomosis was performed between a "J"-shaped colonic reservoir and the anal sphincter, except in 3 patients who underwent a straight end-to-end coloanal suture without pouch. A defunctionalized stoma was made in 18 cases. Mortality within 30 days of operation was 9%. Specific complications occurred in 2 patients (9%). Mean follow-up in this series was 20.2 +/- 11.7 months (+/- standard deviation). Fifteen patients were alive and free of disease up to 54 months after surgery. One patient was found to have local recurrence at 19 months. The actuarial 3-year survival rate was 73% in the whole group (operative mortality included). Functional results were good in 16 of 19 patients, with an average 1.8-2.9 stools/24 hours and the continence rate was good. Three patients had complications requiring a permanent colostomy. From these preliminary results, coloanal anastomosis appears to be satisfying in regard to oncologic results and affords good anal function, even in the elderly patient (over 62 years of age).
