The artificial bowel sphincter for faecal incontinence: a single centre study.

BACKGROUND AND AIMS: Faecal incontinence (FI) is a socially devastating problem. The treatment algorithm depends on the aetiology of the problem. Large anal sphincter defects can be treated by sphincter replacement procedures: the dynamic graciloplasty and the artificial bowel sphincter (ABS). MATERIALS AND METHODS: Patients were included between 1997 and 2006. A full preoperative workup was mandatory for all patients. During the follow-up, the Williams incontinence score was used to classify the symptoms, and anal manometry was performed. RESULTS: Thirty-four patients (25 women) were included, of which, 33 patients received an ABS. The mean follow-up was 17.4 (0.8-106.3) months. The Williams score improved significantly after placement of the ABS (p < 0.0001). The postoperative anal resting pressure with an empty cuff was not altered (p = 0.89). The postoperative ABS pressure was significantly higher then the baseline squeeze pressure (p = 0.003). Seven patients had an infection necessitating explantation. One patient was successfully reimplanted. CONCLUSION: The artificial bowel sphincter is an effective treatment for FI in patients with a large anal sphincter defect. Infectious complications are the largest threat necessitating explantation of the device.
