Artificial Anal Sphincter

The artificial anal sphincter represents, together with the dynamic graciloplasty, the surgical options for end-stage fecal incontinence when other procedures, including gracial nerve stimulation, have failed or are inapplicable. The indications for implantation of an artificial anal sphincter correspond to those for dynamic graciloplasty with the exception of the requirement of a reasonably good perineal status. In published series the overall explantation rate is about 25%. Infection and erosion to the anal canal or perineal skin are the most serious complications.
