An anal incontinence treatment apparatus comprises an adjustable restriction device implanted in a patient, who suffers from anal incontinence. The device engages a portion of the colon or rectum of the patient to restrict the fecal passageway. An adjustment device mechanically adjusts the restriction on device to restrict or release the fecal passageway, i.e. to normally close the fecal passageway and open the fecal passageway when the patient wants to relieve himself or herself.
