Free jejunal flap: rebuilding the throat with small bowel | CION Cancer Clinics
A free jejunal flap rebuilds the throat using a short piece of your own small bowel, after the throat has been removed for cancer. The bowel is moved to the neck, its tiny blood vessels are joined to vessels there under a microscope, and it is stitched between the back of the mouth and the food pipe. The food pipe and stomach stay in place. This page explains the trade-offs and recovery. CION Cancer Clinics’ surgical oncologists in Hyderabad can talk this through with you.

The short answer
What is a free jejunal flap reconstruction?
A free jejunal flap uses a short piece of your own small bowel to rebuild the throat after it has been removed for cancer. The piece is taken from the upper part of the small bowel, called the jejunum, moved to the neck, and joined to the back of the mouth above and the food pipe below.
What "free" means
The piece of bowel is fully cut away from its blood supply in the abdomen. In the neck, the surgeon then joins its tiny artery and vein to blood vessels there, using a microscope. If those small joins stay open, the bowel lives and heals in its new place.
Why bowel is a good match for the throat
The small bowel is already a soft, moist tube about the right width. Its lining makes mucus, which helps food slide down. Because it replaces only the throat, the food pipe and stomach stay where they are and the chest is not operated on.
When it is used
It suits a throat cancer that has been removed as a full ring, when the lower edge of the cancer stops high enough in the neck to leave healthy food pipe to join to.
Weighing it up
What are the advantages and the drawbacks?
Every reconstruction is a trade. These are the points surgeons weigh when choosing this one.
What it offers
- A natural, moist tube for swallowing
- No surgery inside the chest
- The stomach keeps working as before
- Well suited to a full ring of throat removed
What it asks of you
- A second operation site in the abdomen
- Two joins in the neck instead of one
- Close checks on the flap's blood supply in the first days
The biggest early risk
A clot can block the tiny joined blood vessels. If that happens, the flap loses its blood supply and usually needs an urgent return to theatre. This is why nurses check the flap so often at first.
The effect on voice
The bowel keeps making mucus and moving on its own. People who speak with a voice valve sometimes find their new voice sounds wetter or more bubbly than with other repairs.
The effect on swallowing
Because the bowel lining stays moist, many people find food slides down comfortably. The bowel can squeeze out of step with swallowing, though, so some foods may pause on the way down at first. This often settles with practice.
Not sure whether this applies to you?
Ask an oncologistAfter the operation
What happens in the days after a jejunal flap?
-
Waking in intensive care
You breathe through the stoma in your neck, with drains in the neck and a dressing on the abdomen. You are fed through a tube.
-
Frequent flap checks
Nurses check the flap's colour and blood flow many times a day. Sometimes a small window of bowel is left visible on the neck skin to make this easier. It is removed later, usually at the bedside.
-
The abdomen recovers
The bowel that was left behind is rejoined during the operation. It takes a little while to start working again, and you may feel bloated before it settles.
-
Testing the new throat
Once the team is happy the joins have healed, sometimes after a swallow X-ray, you start with sips of water and move on slowly.
-
Swallowing and voice therapy
A speech and swallowing therapist works with you before and after you go home, on eating safely and on your new voice.
On your report
What do the words on the surgical notes mean?
- Jejunum
- The first long stretch of the small bowel, after the stomach. Only a short piece is taken, and digestion carries on normally.
- Free flap
- Tissue moved with its own artery and vein, which are joined to new vessels at its new site.
- Anastomosis
- A join. Notes may mention joins of the bowel to the throat and food pipe, and joins of the blood vessels.
- Monitor segment
- A small piece of the flap left visible on the skin so its blood flow can be seen. It is removed once the flap is safe.
- Flap failure
- The flap has lost its blood supply and cannot survive. It is removed and another repair is used.

After going home: what cannot wait
If saliva, milk or food starts leaking through the neck wound, or the neck becomes red, hot and swollen, or you develop a fever with these, contact your surgical team or go to the emergency department the same day. These can be signs of a leak at the join. Do not keep eating by mouth while you wait to be seen.
Commonly believed
What do families worry about that is not true?
"Taking out part of the bowel will ruin digestion."
Only a short piece of a very long bowel is used. The two ends are rejoined, and most people digest food normally once the abdomen has healed.
"Food will taste of the bowel."
Taste comes from the tongue, which is not changed. The flap only carries food down. Some people notice more mucus in the throat, which is different from a change in taste.
"If the flap fails, nothing else can be done."
Flap failure is serious, but there are other options. A different flap, such as a rolled skin flap from the thigh or forearm, can usually be used to rebuild the throat.
"A microscope operation must be experimental."
Joining small blood vessels under a microscope is a long-established part of head and neck reconstruction. What matters is that the team does it regularly. Ask how often your centre does.
Being straight with you
Who is a jejunal flap not the right choice for?
A jejunal flap needs healthy food pipe in the neck to join to. If the cancer reaches down into the chest, there is nothing safe to join the lower end to, and a gastric pull-up is usually used instead.
When the abdomen or neck vessels are a problem
Previous major abdominal surgery can leave scarring that makes taking bowel difficult. Heavy radiotherapy or earlier neck surgery can leave too few healthy blood vessels in the neck to join to. In these situations a skin flap from the thigh or forearm may be preferred.
When fitness is the concern
Adding an abdominal operation lengthens the anaesthetic. For some people, a repair that avoids the abdomen is gentler.
What this page cannot tell you
It cannot tell you which reconstruction your surgeon will choose, or how your swallowing and voice will turn out. Ask why this repair was chosen over the others, and what the plan is if it does not take.
Questions we are asked
Common questions about jejunal flaps
Is the flap taken in the same operation?
Yes. Usually one team removes the cancer from the neck while another opens the abdomen and prepares the piece of bowel. The flap is then moved to the neck and joined in place, all under the same anaesthetic.
Will I have a scar on my tummy?
Yes. The bowel is taken through a cut in the abdomen, usually down the middle, or sometimes through smaller keyhole cuts. It heals like other abdominal scars. You will be asked not to lift heavy things for a while as it heals.
Why is a small piece of bowel showing on my neck?
That is a monitor segment. It lets nurses see at a glance whether the flap has a good blood supply. It looks unusual but is expected. Once the flap is safe, it is tied off and removed, usually at the bedside, and the skin heals over.
Will the bowel in my throat make noises or move?
The bowel can keep squeezing on its own for a while, and some people notice gurgling or a feeling of movement. It can also make extra mucus. Both tend to ease over the months. Tell the swallowing therapist if either troubles you.
Can I speak with a voice valve after a jejunal flap?
Many people can. A valve placed between the windpipe and the new throat lets air vibrate the tissue to make sound. The voice can sound wetter than with other repairs, because of the mucus. A speech therapist helps you get the most from it.
What if food starts sticking months later?
The lower join sometimes narrows as it heals. Food sticking, or needing to drink to wash food down, is a sign. It is usually treated by gently stretching the join with a scope. It can also be a sign of the cancer returning, so tell your team rather than waiting.
How is the flap checked if it is inside my neck?
Apart from a monitor segment, nurses may use a small handheld device that listens for blood flow in the flap. They also watch the neck for swelling and the drains for changes. Any worry is reported to the surgeon at once.
Is a jejunal flap covered by Aarogyasri or insurance?
Major head and neck cancer surgery with reconstruction is usually covered under Aarogyasri, CGHS, ECHS, EHS and most cashless insurance policies, subject to approval and cover limits. Call the helpline with your card or policy details and we will check before admission.
