Preliminary results of peripheral transcutaneous neuromodulation in the treatment of idiopathic fecal incontinence.
OBJECTIVE
Few therapeutic tools are available for treating idiopathic anal incontinence. Sacral neuromodulation appears to be effective in selected patients but requires surgical implantation of a permanent electrical stimulator. The aim of this work was to assess the efficiency of posterior tibial nerve (PTN) transcutaneous electrical nerve stimulation (TENS) in the treatment of anal idiopathic incontinence.


METHODS
Ten women were treated by PTN TENS, 20 min a day for 4 weeks. Functional results were evaluated by Wexner's incontinence score and anorectal manometry.


RESULTS
Eight of the ten patients showed a 60% mean improvement of their incontinence score after 4 weeks. This improvement remained stable over the 12-week follow-up period. Manometric parameters did not differ before and after stimulation.


CONCLUSIONS
PTN neuromodulation without surgically implanted electrode could represent a safe and low-cost alternative to permanent sacral neuromodulation for idiopathic anal incontinence.
