[Rectal prolapse]. / Le prolapsus du rectum.

Rectal prolapse and rectal intussuception correspond to two stages of the same disease. Rectal prolapse is unusual but requires surgical treatment. Abdominal rectopexy is the most effective procedure but increases the risk of postoperative constipation. This risk decreases when the lateral sides are not touched during rectal dissection. The Delorme procedure is associated with a higher rate of recurrence and must be reserved for patients presenting a high risk of postoperative complications. Rectal intussuception is more frequent and is pathological only when arising in the anal sphincter. Rectal intussuception may lead to solitary rectal ulcer and has in this case to be treated by rectopexy. Rectal intussuception involvement in terminal constipation is not yet proved. Internal mucosectomy seems to be the best treatment for terminal constipation.
