Pelvic exenteration

Pelvic exenteration (or pelvic evisceration) 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 urinary diversion. In women, the vagina, cervix, uterus, fallopian tubes, ovaries and, in some cases, the vulva are removed. In men, the prostate is removed.

Indications

Pelvic exenteration is an option in cases of very advanced or recurrent cancer, for which less radical surgical options are not technically possible or would not be sufficient to remove all the tumor. This procedure is performed for several types of cancer including genitourinary and colorectal cancers.

A 2015 article reports that pelvic exenteration can provide long-term survival for patients with locally advanced primary rectal carcinoma. The 5-year survival rate of patients undergoing pelvic exenteration following complete resection of disease was 59.3%. Factors shown to influence the survival rate following a pelvic exenteration procedure include age, the presence of metastatic disease, lymph node status, circumferential resection margin, local recurrence of disease, and the need for neoadjuvant therapy.[1]

Complications

After pelvic exenteration, many patients will have perineal hernia, often without symptoms, but only 3–10% will have perineal hernia requiring surgical repair.[2]

History

The procedure was first described by Alexander Brunschwig in 1948.[3][4]
