Long-Term Results of Artificial Anal Sphincter Implantation for Severe Anal Incontinence

Abstract

An AAS based on the same principles as the artificial urinary sphincter seems to be a valid alternative in selected patients when standard surgical procedures have failed or are unsuitable. Approximately half of the patients have an adequate long-term result. Infectious complications still present a problem, whereas mechanical problems are less frequent with the modification of the device now available.
