[Passive electrostimulation therapy of the anal sphincter is inferior to active biofeedback training]

Anal incontinence can be treated by conservative therapy if a significant anatomical sphincter defect has been excluded. We compared electrostimulation therapy with biofeedback training in a prospective study. Results showed that up to two thirds of all patients can be treated successfully, whereby the results of biofeedback were better than those of electrostimulation.
