Bowel Perforation
A hole in the intestinal wall that requires emergency surgery
Quick Facts
- Type: Gastrointestinal emergency
- Common causes: Ulcers, diverticulitis, trauma, blockage
- Main danger: Peritonitis and sepsis
- Seek urgent care: Sudden severe abdominal pain, rigid belly, fever
Overview
Bowel perforation is a hole that develops through the full thickness of the stomach or intestinal wall. When this happens, digestive juices, food, and bacteria spill into the abdominal cavity, where they cause inflammation and infection of the lining of the abdomen (peritonitis). Without prompt treatment this can rapidly progress to a body-wide infection called sepsis.
A perforated bowel is a surgical emergency. The longer treatment is delayed, the more serious the infection becomes. Quick recognition, antibiotics, and surgery to close the hole and clean the abdomen are usually needed to save the person's life. The seriousness depends partly on where the hole is and what leaks out: contents from the lower bowel carry large numbers of bacteria and tend to cause more severe infection, while a small, contained leak higher in the digestive tract may be slightly less explosive. In every case, however, prompt medical care is essential.
Symptoms
Symptoms usually come on quickly and are severe. Classic signs include:
- Sudden, severe abdominal pain that may start in one area and spread
- A hard, rigid, or board-like belly that is very tender to touch
- Pain that worsens with movement, coughing, or pressing on the abdomen
- Nausea and vomiting
- Fever and chills
- A rapid heartbeat and rapid breathing
- Bloating and inability to pass gas or stool
As infection sets in, a person may become confused, very weak, or develop dangerously low blood pressure. These are signs of a life-threatening emergency.
Causes
A perforation can occur anywhere along the digestive tract. Common causes include:
- Peptic ulcers: A deep stomach or duodenal ulcer can erode all the way through the wall.
- Diverticulitis: Inflamed pouches in the colon can burst.
- Bowel obstruction: A severe blockage can raise pressure until the wall tears.
- Appendicitis: A burst appendix.
- Trauma: A blunt blow or penetrating wound to the abdomen.
- Inflammatory bowel disease, infection, or cancer that weakens the wall.
- Medical procedures: Rarely, an endoscopy or surgery.
Risk Factors
- History of peptic ulcers, especially with NSAID painkiller use
- Diverticular disease of the colon
- Inflammatory bowel disease such as Crohn's disease
- A bowel blockage or appendicitis
- Abdominal trauma
- Recent abdominal surgery or endoscopy
- Older age and weakened immune system
Diagnosis
Doctors work quickly to confirm a perforation and find its source:
- Physical examination: A rigid, very tender abdomen strongly suggests perforation.
- Imaging: An upright X-ray or, more often, a CT scan can show free air that has leaked outside the bowel into the abdomen, the key sign of perforation. A CT scan can also help locate the hole and reveal its likely cause.
- Blood tests: To check for infection, organ function, and signs of sepsis.
Because the condition can worsen quickly, doctors often act on a strong clinical suspicion rather than waiting for every test result, especially when the abdomen is rigid and the person is unwell.
Treatment
Treatment almost always requires urgent surgery along with supportive care.
- Stabilization: Intravenous fluids, broad-spectrum antibiotics, and pain control are started immediately.
- Surgery: The surgeon closes or removes the damaged section of bowel, repairs the hole, and washes out the contaminated abdomen. In some cases a temporary colostomy is created to divert stool while the bowel heals.
- Intensive care: Severe cases with sepsis may need monitoring in an intensive care unit.
A small, contained perforation may occasionally be treated with antibiotics and close observation, but most cases need an operation.
Prevention
- Treat peptic ulcers promptly and use NSAID painkillers cautiously
- Manage diverticular and inflammatory bowel disease with your doctor
- Do not ignore worsening abdominal pain or signs of a bowel blockage
- Seek care early for severe abdominal pain or possible appendicitis
- Wear a seatbelt to reduce abdominal trauma in collisions
When to See a Doctor
Bowel perforation is a medical emergency. Call emergency services or go to the nearest emergency department immediately if you have:
- Sudden, severe, or rapidly worsening abdominal pain
- A hard, rigid abdomen that is extremely tender to touch
- Fever with abdominal pain and vomiting
- Inability to pass gas or stool with a swollen belly
- Confusion, fainting, or a racing heartbeat
Do not wait or take painkillers and hope the pain passes; early treatment greatly improves the outcome.
Frequently Asked Questions
Is bowel perforation an emergency?
Yes. A perforated bowel lets digestive contents and bacteria leak into the abdomen, causing peritonitis and, if untreated, life-threatening sepsis. It needs immediate emergency care and almost always urgent surgery.
What does the pain of a bowel perforation feel like?
It usually causes sudden, severe abdominal pain along with a hard, rigid belly that is very tender to touch. The pain often worsens with movement or coughing and is frequently accompanied by fever, nausea, and a racing heartbeat.
How is a bowel perforation diagnosed?
Doctors examine the abdomen and order imaging, usually a CT scan or upright X-ray, which can show free air that has leaked outside the bowel. Blood tests help assess infection and organ function.
Can a bowel perforation heal without surgery?
Most perforations require surgery to close the hole and clean the abdomen. Occasionally a small, contained perforation is treated with antibiotics and close monitoring, but this decision is made by a surgical team based on imaging and the patient's condition.
