Pelvic Exenteration
What is Pelvic Exenteration?
Pelvic exenteration is a major surgical procedure used to treat advanced or recurrent cancers located within the pelvis when other treatment options are unlikely to be effective. It involves removing one or more organs from the pelvic cavity, depending on the location and extent of the cancer.
The procedure may include removal of the bladder, prostate, rectum, portions of the bowel, and surrounding tissues. In some cases, nearby lymph nodes and reproductive organs may also be removed. Pelvic exenteration is most commonly performed for locally advanced or recurrent bladder, prostate, rectal, gynaecological, or other pelvic cancers, with the goal of achieving complete removal of the disease.
What are the Benefits of Pelvic Exenteration?
Although it is an extensive operation, pelvic exenteration can offer significant benefits for carefully selected patients.
Benefits include:
- Potentially curative treatment for selected locally advanced or recurrent pelvic cancers
- Complete removal of cancer confined to the pelvis
- Relief of symptoms such as pain, bleeding, urinary obstruction, or bowel obstruction
- Improved quality of life when cancer-related symptoms are severe
- May provide long-term cancer control in appropriate patients
- Individualised reconstructive techniques to restore urinary and bowel function where possible
When is Pelvic Exenteration Recommended?
Pelvic exenteration is considered only after careful assessment by a specialist multidisciplinary cancer team.
It may be recommended for:
- Locally advanced bladder cancer involving surrounding pelvic organs
- Recurrent pelvic cancer following previous surgery or radiotherapy
- Selected cases of advanced prostate cancer
- Certain colorectal cancers confined to the pelvis
- Advanced gynaecological cancers
- Pelvic cancers causing severe pain, bleeding, fistulas, or obstruction
- Patients who are medically fit for major surgery and have no evidence of widespread metastatic disease
Extensive imaging and investigations are required to determine whether complete removal of the cancer is achievable.
What does Preparation for Pelvic Exenteration Involve?
Preparation begins several weeks before surgery and involves detailed planning by multiple specialists.
Preparation may include:
- CT, MRI, and PET scans to assess the extent of the cancer
- Blood tests and cardiac assessment
- Nutritional evaluation and optimisation
- Review of medications, including blood-thinning medicines
- Bowel preparation if intestinal surgery is planned
- Consultation with stoma care specialists if urinary or bowel diversion will be required
- Discussion with anaesthetists, specialist nurses, and rehabilitation teams
Patients receive detailed counselling regarding the procedure, expected recovery, and long-term lifestyle changes before giving informed consent.
How is Pelvic Exenteration Performed?
Pelvic exenteration is performed under general anaesthetic and typically takes several hours to complete. The exact operation depends on the organs affected by the cancer.
The surgeon carefully removes all cancerous tissue, which may include the bladder, prostate, rectum, portions of the bowel, lymph nodes, and other surrounding structures. The primary objective is to achieve complete removal of the tumour with clear surgical margins while preserving as much healthy tissue as possible.
If the bladder is removed, urinary diversion is created, often using a section of bowel to form an ileal conduit or, in selected patients, a continent urinary reservoir. If the rectum is removed, a permanent colostomy may be necessary. Reconstructive surgery may also be performed to restore pelvic support and improve function where appropriate.
Throughout the procedure, meticulous surgical technique is used to minimise blood loss and protect surrounding nerves and blood vessels whenever possible.
What to Expect during Recovery after Pelvic Exenteration?
Recovery following pelvic exenteration is longer than for most urological procedures.
Patients typically remain in hospital for one to three weeks, depending on the complexity of the surgery and their overall recovery. During this time, the healthcare team closely monitors wound healing, bowel function, urinary diversion, nutrition, and pain control.
During recovery, patients can expect:
- Gradual return to eating and drinking
- Early mobilisation with physiotherapy support
- Education on caring for a stoma or urinary diversion if required
- Regular follow-up appointments and imaging
- A gradual return to daily activities over several months
Ongoing support from specialist nurses, physiotherapists, dietitians, and cancer care teams plays an important role in recovery.
What are the Risks and Complications of Pelvic Exenteration?
As one of the most complex operations in pelvic cancer surgery, pelvic exenteration carries significant risks that should be carefully considered.
Possible complications include:
- Bleeding requiring blood transfusion
- Infection
- Blood clots in the legs or lungs
- Wound healing problems
- Urinary or bowel leakage
- Injury to surrounding organs or blood vessels
- Stoma-related complications
- Changes in urinary, bowel, and sexual function
- Need for additional procedures if complications occur
Your specialist urological cancer team will carefully assess whether pelvic exenteration is appropriate for your individual circumstances and discuss the expected benefits, potential risks, and available alternatives before treatment proceeds.
