Duodenectomy: when only the duodenum is removed | CION Cancer Clinics
A duodenectomy is an operation to remove all or part of the duodenum, the first stretch of small bowel just beyond the stomach, while the pancreas stays in place. It is used for a small group of growths, often precancerous polyps or tumours lower in the duodenum. This page explains the different versions, what happens around the operation, and what it cannot decide for you. CION Cancer Clinics’ surgical oncologists in Hyderabad can talk this through with you.

The short answer
What is a duodenectomy?
A duodenectomy removes all or part of the duodenum, the C-shaped tube that carries food out of the stomach. The pancreas, the bile duct and the stomach are left in place, which is what makes it different from a Whipple operation.
Why the duodenum is a delicate place to operate
The duodenum is short, but a lot meets there. The bile duct from the liver and the main duct from the pancreas both empty into it through a small opening called the ampulla. The pancreas wraps tightly around its curve. Any operation here has to protect those connections, or rebuild them, so digestive juices still reach your food.
When a surgeon considers it
It is usually considered when a growth is confined to the duodenum and does not need the head of the pancreas removed with it. That often means a large polyp that cannot be removed safely through an endoscope, many polyps in someone with an inherited polyp condition, or a tumour in the lower duodenum, well away from the ampulla.
Different versions
What kinds of duodenectomy are there?
The name covers a few different operations. Which one your team discusses depends on where the growth sits and what it is.
Segmental duodenectomy
Only the affected section is removed, most often the third or fourth part of the duodenum, which lies below the ampulla. The cut ends are then joined back to the small bowel.
Often discussed for
- Tumours in the lower duodenum
- Some gastrointestinal stromal tumours (GIST)
- Some neuroendocrine tumours
Pancreas-sparing total duodenectomy
The whole duodenum is removed. The bile and pancreatic openings are stitched into a loop of small bowel, and the stomach is joined to that same loop so food can pass on.
Often discussed for
- Many polyps from an inherited condition
- Large polyps covering much of the lining
Local excision
The duodenum is opened and a small growth, sometimes at the ampulla itself, is cut out with a rim of normal tissue. The wall is then closed. It removes the least, and suits the fewest growths.
Usually kept for growths that are not invasive cancer.Not sure whether this applies to you?
Ask an oncologistThe pathway
What happens, from the first scan to going home?
-
Tests to map the growth
An endoscopy with a biopsy, a small tissue sample, tells the team what the growth is. A CT scan, and often an endoscopic ultrasound, show how deep it goes and how close it sits to the ampulla and pancreas.
-
Tumour board
Surgeons, gastroenterologists, radiologists and oncologists look at the results together. They agree whether the growth can come out through the scope, needs a duodenectomy, or needs a larger operation.
-
The operation
It is done under general anaesthesia, through a cut in the upper tummy or by keyhole in selected cases. Ask your centre which approach they plan and how often they perform this operation.
-
The first days
You will have a drain near the joins, a drip, and often a tube to drain the stomach or to feed you. The team checks the drain fluid for signs of a leak before you start eating.
-
Going home
You go home once you are eating, walking and the drains are out or planned for removal. Recovery at home usually takes several weeks.
On your report
Which words will you see on the reports?
- Duodenum
- The first part of the small bowel, just after the stomach. Reports divide it into four parts, counted from the stomach downwards.
- Ampulla (ampulla of Vater)
- The small opening where bile and pancreatic juice enter the duodenum. How close a growth sits to it shapes the choice of operation.
- Adenoma
- A polyp that is not cancer, but can turn into cancer over time if it is left.
- High-grade dysplasia
- Cells in a polyp that look very abnormal under the microscope. It is a warning stage before invasive cancer.
- Margin
- The rim of normal tissue around what was removed. A clear margin means no abnormal cells were found at the edge.
- Anastomosis
- A join the surgeon makes between bowel and bowel, or a duct and the bowel.

After you go home: what cannot wait
Go to the nearest emergency department the same day if you have a fever with shivering, tummy pain that is getting worse, vomiting that will not stop, yellowing of the eyes or skin, black or bloody stools, or fluid from the wound or drain site that changes colour or smells. Take your discharge summary and say you have had an operation on the duodenum. Do not wait for your follow-up date.
Commonly believed
What do families often believe about this operation?
"Removing less always means less risk."
Keeping the pancreas avoids some problems, but the joins to the bile and pancreatic openings are delicate, and leaks can still happen. A smaller operation is not automatically a safer one. Ask your surgeon to explain the risks of the version planned for you.
"If the polyp is not cancer, surgery can wait for years."
Some polyps stay the same for a long time and can be watched with regular endoscopy. Others are large or show high-grade dysplasia, which means the chance of cancer is building. The timing is a decision for your team, based on the biopsy and how the polyp has changed.
"Without a duodenum you cannot digest food."
Digestion begins in the duodenum, but the rest of the small bowel does most of the work. Bile and pancreatic juice are redirected so they still meet your food. Many people change how they eat for a while, and some need enzyme capsules with meals.
"An endoscope can remove anything, so surgery is outdated."
Endoscopic removal is used whenever it is safe, and it is often tried first. It has limits. Very large, flat or deep growths, or growths that keep coming back, may not come out safely through a scope.
Being straight with you
Who is it not for, and what can this page not tell you?
A duodenectomy does not suit everyone with a growth in the duodenum. It is usually not the operation when an invasive cancer sits at or near the ampulla, or when lymph nodes around the pancreas need to come out. In those cases a Whipple is often discussed instead, because it removes the surrounding nodes as well.
When the body may not cope with a major operation
Serious heart or lung disease, severe frailty or a large recent weight loss can make any major abdominal operation harder to recover from. Sometimes the team suggests building up strength first. Sometimes endoscopic treatment or careful follow-up is the safer path. That judgement belongs to your treating team, who know your full history.
What this page cannot tell you
It cannot tell you whether this operation is right for you, how long your stay will be, or what the pathology report will show afterwards. Those depend on your scans, your biopsy and your general health. Take three questions to your surgeon: which version is planned, why, and what happens if the growth turns out larger than expected.
Questions we are asked
Common questions about duodenectomy
Is a duodenectomy a major operation?
Yes. Even though the pancreas is kept, it is major surgery on the upper tummy, done under general anaesthesia, with a hospital stay and several weeks of recovery at home. The joins made to the bile and pancreatic openings need close watching in the first days. Your surgeon will explain which risks apply to your version.
How is it different from a Whipple operation?
A Whipple removes the duodenum together with the head of the pancreas, the lower bile duct and the gallbladder, and sometimes part of the stomach. A duodenectomy removes the duodenum, or part of it, and keeps the pancreas. It is smaller, but it cannot remove the lymph nodes that a cancer near the pancreas may have reached.
Will I get diabetes afterwards?
It is less likely than after operations that remove part of the pancreas, because the pancreas stays in place. Blood sugar can still rise for a while after any major operation. If you already have diabetes, your doctors may adjust your medicines in hospital. Do not stop or change them on your own.
Can it be done by keyhole or robotic surgery?
Some centres use keyhole or robotic methods for selected patients, particularly for segmental operations. It depends on the growth, your build, earlier operations and the surgeon's experience. Ask your centre which approach they plan for you, how often they use it for this operation, and when they would switch to open surgery.
How long will I be in hospital?
It varies more than most families expect. You stay until you are eating, walking, passing wind or stools, and any drain has been checked. A leak or a stomach that is slow to empty can add days. Ask your team what a usual stay looks like at their centre and what would make yours longer.
What will I be able to eat afterwards?
You start with sips and move to soft food as your stomach wakes up. Many people feel full quickly and do better with small, frequent meals. Some need pancreatic enzyme capsules with food. A dietitian should see you before you go home. Report any ongoing weight loss rather than putting up with it.
Will I need chemotherapy after surgery?
It depends on the pathology report. If the growth was a polyp without invasive cancer, further treatment is usually not needed, though regular endoscopy often continues. If invasive cancer is found, the tumour board discusses whether treatment after surgery, called adjuvant treatment, would help in your case.
Is it covered by Aarogyasri or my insurance?
Cover depends on the diagnosis, the scheme and the hospital. Aarogyasri, CGHS, ECHS and EHS can cover cancer surgery when the paperwork is in order, and many cashless insurers do too. What you pay yourself is often very different from the listed price. Call the helpline with your card details to check your own cover.
