[Direct and reservoir colonic-anal anastomoses. Short and long term results].
OBJECTIVE
This retrospective study was designed to assess the operative, oncologic and functional results of total proctectomy with coloanal anastomosis (CAA).


METHODS
Between 1990 and 1994, 81 patients (44 males/37 females: mean age: 59 years) were operated for a cancer (n = 67) or a benign lesion (n = 14) of the rectum. Sixty-four patients had a straight CAA and 17 patients had a colonic J-pouch.


RESULTS
There was no operative mortality. Two patients were reoperated for colonic necrosis and underwent abdominoperineal resection. An anastomotic leak was observed in 11 patients and its severity was decreased by a diverting stoma. An anastomotic stricture was observed in 10 patients. Of the 67 patients with cancer, 19 (28%) developed metastases and 11 (16%) developed local recurrence. The 5-year survival rate was 69%. Twelve months after the operation, continence was similar with the two types of CAA, but the mean daily stool frequency was lower in patients with a reservoir. With a long follow-up (mean = 9 years), functional results were good with regard to continence and stool frequency, almost similar with the two types of CAA; functional disorders (noctumal stools, fragmentation, urgency) were reported by 25 to 40% of patients.


CONCLUSIONS
Total proctectomy with coloanal anastomosis yields good oncologic results. With regard to functional results, the superiority of the colonic J-pouch, which is observed in the first postoperative year, was lost beyond this period; long-term results are good for continence and stool frequency, but some disorders persist in a significant proportion of patients.
