Prolapse

Prolapse literally means "to fall out of place", from the Latin prolabi meaning "to fall out". In medicine, prolapse is a condition where organs, such as the uterus, fall down or slip out of place. It is used for organs protruding through the vagina or the rectum or for the misalignment of the valves of the heart. A spinal disc herniation is also sometimes called "disc prolapse".

Relating to the uterus, prolapse condition results in an inferior extension of the organ into the vagina, caused by weakened pelvic muscles.

The main type of prolapse of heart valves in humans is mitral valve prolapse (MVP), which is a valvular heart disease characterized by the displacement of an abnormally thickened mitral valve leaflet into the left atrium during systole.

Tricuspid valve prolapse can cause tricuspid regurgitation.

Rectal prolapse is a condition in which part of the wall or the entire wall of the rectum falls out of place. Rectal prolapse can be a medical emergency. In some cases, the rectum may protrude.

Symptoms of a rectal prolapse may be:

A surgeon may operate through the abdomen to secure part of the large intestine or rectum to the inside the abdominal cavity (rectopexy). Sometimes the surgeon removes the affected part of the intestine.

Surgery also can be done through the perineum (the area between the genitals and the anus) to remove the prolapsing tissue.

Surgery is most often successful for people who still have some control over their bowel movements. If the anal sphincter is damaged, surgery may correct the prolapse but not be able to completely correct fecal incontinence (lack of control of bowel movements). Fecal incontinence can both potentially improve or worsen after prolapse surgery.
