Pelvic exenteration
Encyclopedia
Pelvic exenteration is a radical surgical
treatment that removes all organs from a person's pelvic cavity
. The urinary bladder
, urethra
, rectum
, and anus
are removed.
The procedure leaves the person with a permanent colostomy
and vesicostomy. In women, the vagina
, cervix
, uterus
, fallopian tube
s, ovaries
, and in some cases the vulva
are removed. In men, the prostate
is removed.
The operation is controversial, because it has not been subject to controlled clinical trials. Barron H. Lerner said that was the extreme case of procedures that provided "little or no benefit, while causing dying cancer patients disfigurement and suffering."
, often without symptoms, but only 3–10% will have perineal hernia requiring surgical repair.

Indications
Pelvic exenteration is most commonly used in cases of very advanced or recurrent cancer, in which less radical surgical options are not technically possible or would not be sufficient to remove all the tumor. This procedure is performed for many types of cancer including genitourinary and colorectal cancers.Complications
After pelvic exenteration, many patients will have perineal herniaPerineal hernia
Perineal hernia is a hernia involving the perineum . The hernia may contain fluid, fat, any part of the intestine, the rectum, or the bladder. It is known to occur in humans, dogs, and other mammals, and often appears as a sudden swelling to one side of the anus.A common cause of perineal hernia...
