Treatment of rectal prolapse by sphincteric support using silastic rods.

The use of silastic perianal rings to control rectal prolapse in the elderly has been reviewed. Forty-one patients were treated over a 6 year period by a total of 52 operations. Their mean age was 80 years and there was no operative mortality. Prolapse was adequately controlled in 71 per cent of patients, and a further three patients had no recurrence despite failure and removal of the ring. The results of this procedure are inferior to those obtained by abdominal operations for rectal prolapse, but deserve serious consideration in those elderly patients who may be unfit for laparotomy.
