Constipation in 44 patients implanted with an artificial bowel sphincter.
OBJECTIVE
Constipation with or without obstructed defecation (OD) is frequent in patients with artificial bowel sphincter (ABS). The aims of this study were (1) to evaluate the functional outcome of ABS based on postoperative constipation and (2) to assess pre-implantation data to predict post-implantation constipation.


METHODS
Thirteen men and 31 women were followed up. Both fecal incontinence and constipation with and without OD were assessed after implantation. Pre-implantation characteristics were compared in patients with and without postoperative constipation.


RESULTS
After implantation, nine patients (20.4%) had constipation without OD, 16 patients (36.4%) had OD, and 19 patients (43.2%) had neither of these. Incontinence was significantly more frequent in patients with postoperative constipation with or without OD. In these patients, an increase in preoperative constipation, anismus, and ultraslow waves was noted.


CONCLUSIONS
Constipation with and without OD is frequent after implantation and interfere with the functional outcome of ABS.
