Electronic anal sphincter stimulation in barium enema examination. A preliminary communication.
Electronic stimulation of the external and sphincter muscle was successful in preventing premature evacuation of barium in 28 of 30 patients. All of them were unable on 1 or more occasions to retain the barium during previously attempted studies by conventional methods. None of the patients had an underlying neurologic problem affecting the anal sphincter. No adverse reactions were noted.
