Long-term functional results of colonic J pouch versus straight coloanal anastomosis

Background: There are very few studies evaluating the long-term functional outcome of coloanal anastomoses. This retrospective study aimed to compare long-term functional results of straight and colonic J pouch anastomoses. Methods: Thirty-seven patients, 25 with a straight anastomosis and 12 with a J pouch anastomosis, responded to a standardized telephone questionnaire. The mean time since surgery was 10 (range 4-18) years. Results: The mean daily stool frequency was similar in both groups of patie nts (1.1 in patients with a reservoir, 1.5 in patients with a straight anas tomosis). In both groups, two-thirds of patients had perfect continence or limited gas incontinence. Faecal incontinence was reported by two patients with a straight anastomosis and one patient with a pouch. Nocturnal stools and fragmentation were slightly more frequent in patients with a straight a nastomosis. Half of the patients regularly used medication. Thirty-five of the 37 patients reported satisfaction with functional results. Conclusion: Long-term functional results of coloanal anastomoses are satisf actory and, unlike early results, similar for both types of anastomosis. Th e functional benefit of a reservoir, seen in the first year after operation , is less evident with increasing time.
