Artificial anal sphincter for faecal incontinence

Bisset A F
Record ID 32004000179
Authors' objectives:

This study aims to assess the effectiveness of artificial anal sphincter (AAS) implantation in people with faecal incontinence.

Authors' recommendations: We found no randomised controlled trials, one non-randomised controlled trial, and 7 case series with more than 20 participants. The studies identified were small and had important methodological weaknesses that substantially reduce their reliability. All the studies identified were in people with severe faecal incontinence of varying aetiology, and complex previous histories. Therefore it would be inappropriate to draw conclusions from these studies regarding the use of AAS in people with less severe faecal incontinence, or with faecal incontinence of a particular aetiology. The only conclusion that can be made from these studies is that AAS implantation is feasible in people with severe faecal incontinence and complex treatment history, and may result in some improvement in continence and quality of life in people in whom the operation is successful. However, early post-operative complication rates were high in all the studies, often requiring removal of the device or further surgery. Later complications also occurred, especially infection and emptying difficulties. The lack of high quality controlled studies mean that it is not possible to determine the relative efficacy and safety of AAS implantation compared to other methods of treating faecal incontinence.
