Overview
Rectal prolapse normally describes a medical condition wherein the walls of the rectum protrude through the anus and hence become visible outside the body.
Classification
There are three chief conditions which come under the title rectal prolapse:
- Full-thickness rectal prolapse describes the entire rectum protruding through the anus
- Mucosal prolapse describes only the rectal mucosa (not the entire wall) prolapsing
- Internal intussusception wherein the rectum collapses but does not exit the rectum
Causes
Progression
The condition of Rectal prolapse, a type of rectal rupture, undergoes progression: beginning with prolapsation during bowel movements, through Valsalva movements (sneezing and so forth), then through daily activities such as walking until finally it may become chronic and ceases to retract.
Treatment
Pharmaceutically, the condition may only be treated secondarily (by treating deficate) so as to avoid further straining.
The alternative is surgery, it may be divided into two forms of procedure: abdominal surgery and perineal surgery.
- Abdominal surgery - for younger patients, but is more dangerous
- Anterior resection
- Marlex rectopexy
- Suture rectopexy
- Resection rectopexy
- Perineal surgery - often performed on older patients and is less dangerous
- Anal encirclement
- Delorme mucosal sleeve resection
- Altemeier perineal rectosigmoidectomy
- Hemorrhoidectomy
- Children are treated with linear cauterization
Notes
Because most sufferers are elderly, the condition is generally under-reported.
