A rectal prolapse occurs when walls of the rectum have prolapsed to such a degree that they protrude out of the anus and are visible outside the body.

Cul-de-sac hernias may be classified as rectal, septal, or vaginal depending on the structure they herniate into. Rectal cul-de-sac hernias herniate into an internal or external rectal prolapse.

External rectal prolapse may give symptoms of obstructed defecation syndrome, fecal incontinence, or both, [16] [6] Other symptoms are bloody or mucous rectal discharge. [6] Relative indications are: Internal rectal prolapse (rectal intussusception), if it causes symptoms. [19] Anterior rectocele, if large and causing symptoms. [5]
The procedure reduces constipation and fecal incontinence in patients with rectal prolapse or rectal intussusception, and has a low rate of complications and recurrence. [64] The procedure is able to correct multiple anatomical defects associated with vaginal and rectal prolapse, as well as improving function in terms of continence and defecation.
"The patient has had rectal prolapse since he was four years old, but the bulge was able to retract in the past," she said. "But he did not have the condition treated, so the situation got worse ...
Sigmoidocele may be internal if it is only detectable on defecography, or external if it detectable without imaging and associated with a rectocele or rectal prolapse. [2] It is a type of posterior compartment prolapse. [4] Sigmoidocele may be classified according to size relative to the pubococcygeal line. [2] [note 1]
