New surgical treatment modalities have been developed for patients wit
h anal incontinence resulting from extensive sphincter destruction and
in whom standard sphincter repair has failed. These new modalities in
clude the transposition of striated skeletal muscles combined with imp
lantation of neurostimulators, artificial sphincters based on the same
principle as artificial urinary sphincters, and direct sacral nerve s
timulation. In a few reported series muscle transposition in combinati
on with neurostimulation has given a satisfactory continence in 50-70%
of the patients. The same is true for the smaller series published on
artificial anal sphincters, whereas the results of sacral nerve stimu
lation have thus far been reported in only a few patients. The selecti
on of patients and the performance of these procedures should be limit
ed to few specialist centres.
