Complications after pelvic exenteration: the honest picture | CION Cancer Clinics
Complications after pelvic exenteration are common, because it is one of the largest operations in cancer surgery. Many people have at least one problem, most often with the wound, an infection or a leak, and most are treated. Some are serious, and there is a real risk of dying. This page explains the common problems, when they appear, why published rates vary so much, and what to ask your own centre. CION Cancer Clinics’ surgical oncologists in Hyderabad can talk this through with you.

The short answer
How often do complications happen after pelvic exenteration?
Complications after pelvic exenteration are common. It is one of the largest operations in cancer surgery, and many people have at least one problem during recovery, most often with a wound, an infection or a leak. Most are treated and settle, but some are serious, and there is a real risk of dying from the operation or its complications.
Why this page gives no single figure
Published rates for this operation vary widely from one report to another. They depend on which complications were counted, for how long people were followed, which cancers were included and how much earlier treatment they had. A number lifted from one study and applied to you could mislead in either direction, so we have chosen not to print one. What the reports do agree on is the shape of it: problems are frequent, most are manageable, and a smaller number are serious.
The figure that matters is your centre's
Ask the team that will operate what their own complication and readmission rates are for this operation, how many they do, and how they count problems. A centre that does these operations regularly should be able to answer plainly.
This page explains what complications are and how they are handled. It cannot tell you your own risk.The pattern
When do complications tend to show up?
-
During the operation
Bleeding is the main concern, because the pelvis is packed with large blood vessels. A blood transfusion is often needed, and the family may be asked to arrange donors beforehand.
-
The first days, often in intensive care
The team watches breathing, blood pressure, kidney function and urine output closely. The bowel is often slow to start working again, so eating is built up gradually.
-
Later in the hospital stay
This is when infections, collections of fluid in the pelvis and leaks from a bowel join or the new urine pathway usually appear. Some need a drain placed under scan guidance; a few need another operation.
-
After going home
Wound breakdown, clots in the legs or lungs, and urine infections can appear after discharge. Coming back into hospital for a spell is common after this operation.
-
Months later
Hernias near a stoma or scar, narrowing of the urine pathway, and bowel blockage from scar tissue can develop well after recovery.
Not sure whether this applies to you?
Ask an oncologistWhat goes wrong
Which complications are most common?
These are the problems surgeons discuss most often before this operation. Not everyone gets any of them.
Wound problems
The wound between the legs is slow to heal and often opens or leaks, especially after earlier radiotherapy. Most are managed with dressings.
Infection and pelvic collections
Fluid can gather in the empty pelvis and become infected. Signs are fever, pain and feeling unwell. Antibiotics and a drain usually treat it.
Leaks
A join in the bowel, or where the ureters meet the new urine pathway, can leak. This is one of the more serious problems.
May need
- A drain or a small tube placed under scan guidance
- Occasionally a return to theatre
A slow bowel
After long pelvic surgery the bowel often stops moving for a while. You may feel bloated and sick, and need a tube through the nose until it recovers.
Clots, chest and heart problems
Long operations and time in bed raise the risk of clots and chest infections. Early walking, breathing exercises and blood thinning injections are used to lower it.

After going home: signs that cannot wait
Go back to the surgical team or the nearest emergency department the same day for fever or shivering, a swollen hard tummy with vomiting, no urine coming into the bag, pain or swelling in one leg, sudden breathlessness or chest pain, heavy bleeding, or feeling confused or very drowsy. Take your discharge summary with you. Do not wait to see if it settles overnight.

Reading the numbers
Why do complication rates look so different in different places?
If you search online, you will find very different figures for the same operation. That does not always mean one centre is safer than another. It usually means they are measuring different things.
What gets counted
Some reports count every problem, including a urine infection treated with tablets. Others count only serious ones that needed another procedure or intensive care. The first kind of report will always show a higher rate.
Who was operated on
A centre treating mainly cancers that have come back after radiotherapy will see more wound problems than one treating first-time cancers. Total exenteration carries more risk than a partial one.
What the numbers do not tell you
A rate describes a group, not a person. Your own risk depends on your fitness, earlier treatment, the extent of the operation and the team. Nobody can promise you will be in the group without problems, and it is fair to be wary of anyone who does.
Ask your surgeon which complications they are most watchful for in your case, and why.Commonly believed
What do families often believe about complications?
"A complication means the surgeon made a mistake."
Complications happen after this operation even in very experienced hands, because of its size and the tissue involved. What matters most is how quickly they are spotted and treated.
"If he has a complication, the cancer operation has failed."
Whether the cancer was fully removed is a separate question, answered by the pathology report. A wound problem or a leak does not change that result.
"We should not ask about rates. It will offend the doctor."
A good team expects this question and should welcome it. Asking how often problems occur, and how they are handled, is part of making an informed decision.
"Once we are home, the risky part is over."
Several complications first appear after discharge. Keep the team's number handy, and know the warning signs before you leave hospital.
On your discharge summary
What do the complication words on the papers mean?
- Anastomotic leak
- A leak from a place where two tubes, such as bowel or ureter, were joined during the operation.
- Pelvic collection or abscess
- A pocket of fluid or pus in the empty pelvis.
- Ileus
- The bowel has temporarily stopped moving food along.
- Clavien-Dindo grade
- A scale surgeons use to grade how serious a complication was, from minor to life-threatening.
- Readmission
- Coming back into hospital after being discharged.
- Return to theatre
- A further operation needed to treat a complication.
Questions we are asked
Common questions about complications after exenteration
What is the most common complication?
Problems with the wound between the legs are among the most common, especially after earlier pelvic radiotherapy. Infections and fluid collections in the pelvis are also frequent. Most are treated with dressings, antibiotics or a drain rather than another big operation, though some do need a return to theatre.
Can someone die from this operation?
Yes, there is a real risk of dying during or after the operation, usually from a serious complication. The size of that risk depends on your fitness, the extent of surgery and the centre. Ask your surgeon directly what it is for you, and what they do to lower it.
Does earlier radiotherapy make complications more likely?
Generally, yes. Tissue treated with radiation heals more slowly and less reliably, so wound problems and leaks are more common. Surgeons often use a flap of healthy tissue to help. Your team will factor earlier treatment into how they plan the operation.
How long could a complication keep us in hospital?
It varies. A minor infection may add a few days, while a leak or a return to theatre can add weeks. Ask the team for a realistic range, so the family can plan work, travel from the district and money without assuming the shortest stay.
Does a complication mean the cancer will come back?
Not in itself. Whether the cancer was fully removed depends on the pathology report on the tissue taken out. A complication can sometimes delay further treatment, such as chemotherapy, and your team will explain whether that applies to you.
What can we do to lower the risk?
Before surgery, stopping all tobacco, controlling blood sugar, eating well and staying as active as you can all help. After surgery, walking early, doing breathing exercises and reporting warning signs quickly make a difference. Follow the team's advice on medicines rather than changing them yourself.
Will complications cost more?
They can, because of extra days, scans, procedures or intensive care. Aarogyasri, CGHS, ECHS, EHS and cashless insurance each handle this differently. Call the helpline with your card details and we will help you understand what your cover includes before the operation.
What should we ask the surgeon about complications?
Ask which complications they are most watchful for in your case, how often their own patients have them, how they are usually treated, and who to call at night after discharge. Write the answers down, or ask a family member to take notes during the appointment.
