|Fecal Incontinence Anal Incontinence||Device: magnetic anal sphincter Device: sacral nerve stimulation||Not Applicable|
Severe anal incontinence, defined as the uncontrolled passing of stool at least once a week, is a problem that has a serious impact on the quality of life. In the event of failure of conservative treatments, surgery can help improve continence problems in a significant number of cases.
Sacral nerve stimulation is currently the standard surgical treatment for severe anal incontinence when sphincter repair (sphincteroplasty) is not recommended.
A new method of treatment based on sphincter reinforcement through the implanting of a band of magnetic beads*, has proved to be reliable and efficient on a small series of cases, particularly after the failure of sacral nerve stimulation.
The aim of our trial, which compares the "magnetic anal sphincter* and sacral nerve stimulation" in a homogeneous population of patients affected by severe anal incontinence is to define the position of this new approach in the treatment algorithm of this functional disorder, determining its clinical and medical/economic advantages compared to those of the current standard treatment.
