Adult malrotation treatment in Ahmedabad · Dr. Jivraj Mehta Hospital, Vasna, Ahmedabad

Malrotation means the intestine did not turn and settle in its usual place before birth. Many adults live with it for years without knowing.

The danger is a twist of the whole small bowel on its narrow stalk, called midgut volvulus. That twist is an emergency, and the operation should not wait.

Ongoing pain from malrotation is treated with an operation called Ladd’s procedure. Malrotation found by chance on a scan is a careful choice between operating and watching.

What malrotation is, and why it can stay hidden

Before birth the gut makes a slow turn and then fixes in place. In malrotation that turn is missed or left half done, and the bowel hangs from a narrow stalk.

The stalk that holds the small bowel is called the mesentery. It carries the main blood vessels to the gut. In a normal belly its base is broad. In malrotation the base can be very narrow, and a narrow base lets the whole small bowel spin on it. That is the one thing that makes this condition dangerous.

Malrotation is not a cancer. It is a difference in how the bowel was laid out before birth. Most children with it are found early. The adults we see are the ones it missed. Some have had vague pain and vomiting for years. Some learn of it only when a CT is done for another reason.

There is no formal international guideline for malrotation in adults. What we advise comes from published case series, reviews of those series and expert opinion. We tell patients this openly, because some decisions below are judgements, not rules.

How malrotation shows up in adults

Adults come in four ways. One is an emergency. One blocks the first part of the bowel. One is years of pain and vomiting. One is a chance finding on a scan.

The four ways adult malrotation presents
PatternWhat the patient notices
Twist of the whole small bowel (midgut volvulus)Sudden, severe belly pain that seems far worse than the belly feels to the doctor. Green or yellow vomit. The patient gets worse fast and may collapse. This is an emergency.
Blockage from Ladd’s bandsBands of tissue cross the first part of the small bowel. Green vomiting and a swollen upper belly.
On and off symptoms for yearsCramping pain that comes and goes, vomiting, bloating, feeling full quickly, weight loss and poor absorption of food. Often labelled irritable bowel or “acidity” for years.
Found by chanceNo symptoms at all. The CT was done for something else.

The emergency: a twisted small bowel

Severe belly pain that is out of proportion to what the doctor feels, with a “whirlpool” twist on CT, means the operating theatre now.

  1. Do not wait for a second scan or a contrast study.
  2. Do not wait for a lactate result. A normal lactate does not rule out a dying bowel.
  3. Do not watch overnight in the ward.
  4. Drip, antibiotics, a stomach tube and blood cross-match are started on the way to theatre, not instead of it.

The blood supply of almost the entire small bowel runs through the twisted stalk. Once it twists, the bowel can die within hours.

That is why we treat the time from suspicion to untwisting as the most important number in this disease. Untwisted in time, the bowel usually recovers. Left too long, long lengths of bowel may need removal. That can leave a person with short bowel syndrome, who may then need feeding through a vein for a long time. If you have been told you have malrotation, say so at once in any emergency department. That one sentence can save hours.

Which test, in what order

A CT scan with contrast through a vein is the key test. Its signs are subtle, so the radiologist is asked to look for them on purpose.

Suspected malrotation: the tests and what each one decides
TestWhat it shows or decides
CT with contrast through a veinThe “whirlpool sign”, where the vein and stalk spiral round the main artery. This is a twist until proved otherwise.
Same CT: the main artery and veinWhether the main gut vein (SMV) lies to the left of the main gut artery (SMA). Normally it lies to the right.
Same CT: the bowel layoutWhether the first part of the small bowel crosses the middle, and where the start of the large bowel (caecum) sits.
Same CT: the bowel wallSigns that the bowel is short of blood: a wall that is too thin or too thick, poor contrast uptake, or gas in the wall or liver veins.
Upper GI contrast study (barium or dye swallow)The reference test for the bowel layout, used only when the patient is stable. It shows where the bowel turns and a corkscrew shape in a twist.
Contrast enemaFinds the caecum when the layout is still unclear.
Blood tests: lactate, blood gas, blood count, kidney testsHow unwell the patient is. They never delay theatre in a suspected twist.

When the history fits, we ask the radiologist about the artery and vein directly. The CT findings are easy to miss if no one is looking for them. That is a common reason the diagnosis is made late.

Malrotation, or something else?

Malrotation is a benign condition present from birth. Before an operation for long-standing pain, other causes are ruled out, because surgery on the wrong cause will not help.

Other causes we check before blaming malrotation for chronic symptoms
ConditionHow it is checked or told apart
Irritable bowel or functional dyspepsiaGut specialist review. If the pain is functional, an operation will not relieve it.
Coeliac diseaseBlood tests and a small bowel biopsy at endoscopy.
Bacterial overgrowth in the small bowelA breath test and the response to treatment.
SMA syndromeA different cause of blocked first bowel, seen on CT. It has its own plan.
Stomach ulcer with a blocked outletEndoscopy. It has its own plan.

Types of malrotation, and what sets the risk

The width of the stalk’s base sets the risk of a twist. A narrow base lets the whole midgut spin. A broad base is more stable.

The anatomy, from highest to lowest twist risk
TypeWhat it means
Non-rotationSmall bowel on the right, large bowel on the left. The stalk base is narrow. This layout carries the highest risk of a twist.
Incomplete rotationThe turn stopped part way. Ladd’s bands often cross the first part of the small bowel.
Reverse rotationRare. The main gut artery lies in front of the large bowel.
Other layoutsSeen with heterotaxy, where organs are on unusual sides, and other birth differences. The heart and spleen are checked too.

Heterotaxy matters before any operation. Some of these patients have no spleen or several small ones, which raises the risk of serious infection. Vaccines and the plan around surgery change because of it.

The treatment ladder for adult malrotation

Treatment depends on how the patient presents. A twist goes to theatre now. Symptoms that are clearly due to malrotation are treated by Ladd’s procedure. A chance finding is a shared decision.

From watching to an emergency operation: who is treated how
SituationUsual plan
Found by chance, no symptomsDiscussed at the team meeting. Either watching with written warning signs, or a planned Ladd’s procedure.
Years of pain and vomitingOther causes ruled out first. If the symptoms are due to malrotation, a planned Ladd’s procedure.
Blockage from Ladd’s bandsLadd’s procedure.
Twist of the small bowelEmergency operation: untwist, assess the bowel, Ladd’s procedure.
Twist with dead bowelEmergency operation, removal of only clearly dead bowel, and a planned second look.

When surgery is not needed

Not every adult with malrotation needs an operation. An older person with no symptoms and a broad stalk base can reasonably be watched.

No guideline settles this, and good surgeons disagree. The case for operating is that a twist is sudden and serious. The case against is that an adult who has reached middle age without a twist has shown some stability. The operation also has its own problems, and later bowel blockage from scar tissue (adhesions) is common after it. These points lean toward watching:

  • An older patient with no symptoms and decades without an episode.
  • A broad stalk base on the CT.
  • Other illnesses that make an operation riskier.
  • A patient who, after a full discussion, prefers to watch.

Watching is not doing nothing. The anatomy and the reasons for the decision are written in the notes. You get written information on the warning signs of a twist and are told to come in at once with severe pain and vomiting. A patient who can say “I have malrotation” in an emergency department has a real safeguard.

When an operation is advised

Ongoing symptoms due to malrotation, a blockage, or a twist all need Ladd’s procedure. For a chance finding, some features tilt the decision toward operating.

  1. Younger age. More years ahead means more years of exposure to a twist.
  2. Non-rotation with a clearly narrow stalk base on the CT.
  3. Past episodes of severe pain with vomiting that settled on their own. These may have been small twists.
  4. Living or travelling far from emergency surgery. A twist is treated in hours, not days.
  5. Your own wish, once fully informed, for a definite treatment.

★★★★★

“I done my stoma closer operation with harsh sir such a nice and kind person never doing miss guide always give right advice polite nature. — Jigar Jadav, Google review”

The reviews below are from Dr Harsh Shah’s two Google listings, quoted exactly as written. None names malrotation. They describe his care of bowel conditions.

Ladd's procedure: what is done, in order

Ladd’s procedure does not put the bowel back in the normal place. It sets the bowel in a safe position and widens the stalk so it cannot twist.

  1. Untwist any twist first. This is usually anticlockwise and often more than one full turn.
  2. Give the bowel time. Bowel that looks dusky just after untwisting often pinks up again after a while.
  3. Divide Ladd’s bands. These are the bands that run from the caecum across the first part of the small bowel.
  4. Widen the base of the stalk. This is the step that stops the twist coming back. It is also the step most often done too little, so it gets full care.
  5. Straighten the first part of the small bowel down the right side of the belly.
  6. Remove the appendix. The caecum ends up on the left, where appendicitis later would be hard to spot.
  7. Settle the bowel: small bowel to the right, large bowel to the left.

A planned Ladd’s procedure for long-standing symptoms can often be done by keyhole surgery in experienced hands. In an emergency with a bowel that is short of blood, open surgery is usually safer, because the whole small bowel needs to be handled, checked and sometimes removed. Our separate page on appendicitis treatment explains why the appendix matters in the belly.

The emergency operation and the second look

In a twist, we remove only bowel that is clearly dead. Doubtful bowel is left and checked again at a second operation one to two days later.

Removing bowel that might have recovered is how a young person ends up with too little bowel for life. So doubtful bowel is given the chance to recover. If the patient is in shock, the bowel ends are not joined in the same sitting. A stoma (a bowel opening on the belly) or a delayed join at the second look is safer. The length of bowel removed, and the length left, are measured and written in the notes, because they decide feeding and follow-up for years.

The two operations are explained to the family before the first one starts. A planned second look is part of the treatment. It is not a sign that something went wrong.

A patient’s own account after release of a blocked small bowel

This patient had an operation to free small bowel blocked by scar tissue (adhesiolysis). Adhesions are also the most common long-term problem after Ladd’s procedure, which is why we talk about them before it.

Preparing for a planned operation

Before a planned Ladd’s procedure, weight loss and nutrition are corrected and the operation is explained with written and visual material.

  1. Nutrition checked and built up where years of symptoms have caused weight loss.
  2. A carbohydrate drink before surgery, as part of an enhanced recovery plan.
  3. Clot-prevention measures and an antibiotic at the start of the operation.
  4. For heterotaxy, a heart and spleen check, and vaccines where the spleen is absent or weak.

In an emergency none of this delays theatre. Resuscitation happens on the way.

Recovery after Ladd's procedure

After a planned operation, most patients eat on day one, walk the same day, and go home in three to five days.

After a planned Ladd’s procedure: the usual day-by-day path
DayWhat happens
Day of surgerySitting out of bed, clear fluids, pain relief with few opioids.
Next dayDiet as tolerated, walking four times, urine catheter and drip removed.
Days 2 to 3Full diet, walking freely, pain tablets by mouth, wind passing.
Days 3 to 5Home, once eating, walking and comfortable on tablets.

After an emergency with damaged bowel the path is different. Care starts in intensive care, the second look comes in one to two days, and nutrition is planned early. If a long length of bowel was removed, feeding through a vein starts early. Recovery is counted in weeks, not days.

Before discharge you receive written notes on the diagnosis, the operation, whether the appendix was removed, and, if bowel was removed, how much remains. Keep these safe. Any future doctor will need all four.

The risks, named in words

The main long-term risk of Ladd’s procedure is later bowel blockage from adhesions. Other risks are named before consent, with the figures that apply to you.

Planned operation: bleeding, wound or port-site infection, clots in the legs or lungs, an anaesthetic problem, a change from keyhole to open surgery, injury to the bowel or its blood vessels, the twist coming back (uncommon), and adhesive blockage in later years. The appendix is removed as part of the operation. For long-standing symptoms, most patients improve, but some go on having pain. That is more likely when symptoms have lasted many years or have another cause as well. The risk to life of a planned operation is small.

Emergency operation for a twist: this is a life-threatening emergency. A second operation is often planned from the start. If a large length of bowel has already died, it must be removed, and short bowel syndrome may follow, with long-term feeding through a vein or a tube. A stoma may be needed. The risk to life depends on how much bowel can be saved: low when it is saved, high when much of it has died. Dr Harsh Shah goes through each of these in person before consent.

Follow-up, and what to keep on record

Follow-up checks the wound, symptoms and weight. After a large bowel removal, care for nutrition continues for life.

Follow-up after malrotation treatment, or a decision to watch
WhenWhat is checked
2 to 6 weeksWound, symptoms, diet and weight.
3 to 6 monthsWhether long-standing symptoms have settled, and nutrition.
After a large bowel removalLifelong review with the intestinal failure team: vitamin B12, fat-soluble vitamins, trace elements, the liver and any feeding line.
Your recordsThe diagnosis, the operation, whether the appendix was removed, and the bowel length left.
Malrotation being watchedWritten warning signs of a twist, a clear instruction to come in at once, and the decision recorded.

One point surprises people. After Ladd’s procedure, new pain on the right side is not appendicitis if the appendix was removed. Doctors need to know this, so show them your operation note. Colicky pain with vomiting months or years later may be adhesive blockage. It needs a scan, and often settles with a drip and rest of the bowel. An operation is needed only if the blood supply is at risk.

Your treatment, from first visit to follow-up

  1. Book your consultation. Bring every CT on a disc, contrast study reports, earlier discharge papers and a list of medicines. Sudden severe pain with vomiting goes straight to the emergency department at Dr. Jivraj Mehta Hospital, Vasna, Ahmedabad.
  2. Read the scans together. The anatomy is confirmed, and the stalk base, the type of rotation and any sign of a twist are noted.
  3. Rule out other causes. For long-standing symptoms, a gut specialist review and tests for other causes come first.
  4. Decide together. Operate, or watch with written warning signs. Either way, the reasons are recorded.
  5. Treatment. A planned keyhole or open Ladd’s procedure, or emergency surgery when a twist is suspected.
  6. Follow-up. Review at 2 to 6 weeks and 3 to 6 months, with your records in hand.

Cost, insurance and admission

A planned Ladd’s procedure and an emergency operation differ widely in cost. An emergency may need intensive care, a second look and longer nutrition support.

The estimate depends on keyhole or open surgery, the hospital stay, and whether intensive care or feeding through a vein is needed. Dr. Jivraj Mehta Hospital, Vasna, Ahmedabad, works with the major insurers and cashless schemes. The office handles pre-authorisation, including for emergency admissions. Bring: CT reports and discs, any contrast study, discharge papers, a list of medicines, the insurance card and identification.

Frequently asked questions

My CT says malrotation, but I have no symptoms. Do I need an operation?

Not always. No guideline settles this. Younger age, a narrow stalk base on CT, past episodes of severe pain with vomiting, or living far from emergency surgery lean toward Ladd's procedure. An older person with no symptoms and a broad base can reasonably be watched, with written warning signs.

What are the warning signs of a twist?

Sudden, severe belly pain that feels out of proportion, with green or yellow vomiting, a swelling belly or feeling faint. Go to the nearest emergency department at once and tell them you have malrotation.

Will Ladd's procedure put my bowel back in the normal place?

No. It sets the bowel in a safe position, widens the base of its stalk so it cannot twist, and removes the appendix. The bowel is left in a non-rotated but safe layout on purpose.

Why is my appendix removed during the operation?

After Ladd's procedure the start of the large bowel sits on the left side. Appendicitis there would be hard to recognise later, so the appendix is removed at the same operation.

Can Ladd's procedure be done by keyhole surgery?

A planned operation for long-standing symptoms can often be done by keyhole surgery in experienced hands. In an emergency twist with bowel short of blood, open surgery is usually safer.

Will my pain go away after the operation?

Most patients with long-standing symptoms improve. Some continue to have pain, more often when symptoms have lasted many years or another cause is also present. That is why other causes are checked first.
