A perforation is a hole in the wall of the stomach or intestine. Once it opens, the contents leak into the abdominal cavity, and infection spreads across the whole abdomen within hours.
This is one of the true surgical emergencies. It does not settle with medicines, it does not improve with waiting, and the delay between the perforation happening and the operation is the single factor most closely linked to how a patient does.
Recognising it
The pain is sudden. Most patients can name the moment it started, often to within a few minutes. It is severe from the outset rather than building gradually.
It usually begins in the upper abdomen and spreads to involve the whole abdomen. Movement makes it worse, so people lie very still, often with their knees drawn up. Coughing or the drive over a speed bump is agonising.
The abdomen becomes hard and rigid to touch, described as board-like. Vomiting, fever and a fast pulse follow. Some people feel pain at the tip of the shoulder, caused by gas escaping and irritating the diaphragm.
Sudden, severe abdominal pain with a hard, rigid abdomen is a surgical emergency. Go to a hospital emergency department immediately. Do not take painkillers and wait, do not wait for morning, and do not wait for an outpatient appointment. Hours matter here.
What causes it
Peptic ulcer is the most common cause. An ulcer in the stomach or the duodenum erodes deeper until it goes all the way through.
The main contributors are H. pylori infection, regular painkillers of the anti-inflammatory type, smoking, alcohol and steroid use. Many patients have had indigestion or burning pain for weeks or months beforehand. Some have had no warning at all.
Typhoid can perforate the small intestine, typically in the second or third week of the illness. This remains an important cause in India and should be considered in anyone with a recent fever illness.
Intestinal tuberculosis can also perforate the small bowel, and is another cause that is relatively common here and easily missed elsewhere.
Other causes include bowel obstruction, a tumour, previous surgery, and injury to the abdomen.
How it is confirmed
An erect chest X-ray is quick and often enough. Free gas escaping from the gut collects under the diaphragm and is visible as a dark crescent.
A CT scan is more sensitive and is used where the X-ray is normal but the suspicion remains, or where the cause and the site of the perforation need identifying before surgery. It should not delay treatment in a patient who is clearly very unwell.
Blood tests show the degree of infection and how the kidneys and other organs are coping.
Before the operation
Surgery is not the first thing that happens, and this is deliberate.
Patients arrive dehydrated and often in the early stages of sepsis. Intravenous fluids, antibiotics, a tube passed into the stomach to empty it, a urinary catheter and pain relief all begin immediately. Taking a patient to theatre without this resuscitation is more dangerous than the short delay it costs.
Once the patient is stabilised, surgery follows promptly.
The operation
Two things have to happen. The hole is closed, and the contamination is cleared.
For a perforated duodenal ulcer, the standard repair closes the hole and reinforces it with a patch of omentum, the fatty tissue that lies over the intestines, stitched over the top.
For a perforated gastric ulcer, the edge of the ulcer is usually sampled and sent for testing at the same time as the repair. This matters, and the reason is explained below.
For small bowel perforation, the hole may be closed directly, or the affected segment removed and the two ends rejoined. Where the contamination is severe or the patient is very unwell, the bowel may be brought out temporarily as a stoma instead of rejoining it immediately, because a join made in an infected abdomen has a high chance of leaking. A stoma in this situation is a safety measure and is often reversed later.
The abdomen is then washed out thoroughly, and drains are usually left in place.
Some perforations can be repaired laparoscopically in patients who are stable and present early. Open surgery is used where the patient is unstable, where the presentation has been delayed, and where contamination is widespread.
Why a perforated stomach ulcer needs follow-up
A gastric ulcer that has perforated can, in a proportion of cases, turn out to be a cancer rather than a simple ulcer. This is why the edge is biopsied during surgery and why an endoscopy is needed weeks later to confirm the ulcer has fully healed. Do not skip this appointment because you feel better.
Duodenal ulcers do not carry this risk in the same way, but they still need the underlying cause treated.
After the operation
The hospital stay is typically five to ten days, and longer if the presentation was late or complications develop. Some patients spend the first days in intensive care.
The stomach tube stays until the gut starts working again. Antibiotics continue for several days. Drains come out once the fluid draining reduces and looks normal.
Eating restarts gradually, liquids first.
Treating the cause, so it does not happen again
Repairing the hole does not treat the ulcer that made it.
You should be tested for H. pylori and treated if positive. Anti-inflammatory painkillers must stop, and if you need painkillers for another condition, alternatives should be arranged rather than resumed quietly. Acid-suppressing medication is prescribed for a defined period. Smoking and alcohol both need addressing.
For a gastric ulcer, a repeat endoscopy is arranged some weeks later to confirm healing.
Risks worth knowing
This is emergency surgery on an unwell patient, and the risks are higher than for planned operations.
Sepsis and organ dysfunction, particularly where the presentation was delayed.
Leak from the repair, which may require a further operation.
Collection of infected fluid inside the abdomen, sometimes needing drainage.
Wound infection, common after contaminated surgery.
Adhesions forming inside the abdomen, which can rarely cause obstruction years later.
Age, delay before treatment and other existing medical conditions all affect the outcome. Early presentation improves it more than anything else.
Recovery at home
Expect to feel tired for several weeks. This was a serious illness, not only an operation.
Eat small, frequent meals initially and build up. Avoid heavy lifting for around six weeks. Take the acid-suppressing medication for the full course rather than stopping when the symptoms go.
Return to hospital if you develop fever, worsening abdominal pain, vomiting, or discharge from the wound.
Frequently asked questions
Can a perforation heal without surgery?
In rare, carefully selected cases where the leak has sealed itself and the patient is stable, non-operative treatment with antibiotics and close monitoring is used. This is the exception. For almost all patients, surgery is required.
How urgent is it really?
Extremely. Outcomes are closely tied to how quickly treatment starts. This is a same-hour condition, not a same-day one.
I had ulcer symptoms for months. Could this have been prevented?
Often, yes. Persistent burning upper abdominal pain, particularly with regular painkiller use, should be investigated and treated. Testing for H. pylori and stopping the causative medication prevents a proportion of perforations.
Will I need a stoma?
Usually not for a perforated ulcer. It is considered in small bowel perforation where contamination is heavy or the patient is very unwell, and it is often temporary.
Can the repair be done by key-hole?
In selected stable patients who present early, yes. Late presentation, instability and heavy contamination usually require open surgery.
Do I need to stay on medication afterwards?
You will be given acid-suppressing treatment for a defined course, and H. pylori treatment if you test positive. Anti-inflammatory painkillers should be avoided unless a doctor specifically clears them.
