Ogilvie Syndrome: Causes, Symptoms, and Treatment

What kind of doctor treats Ogilvie Syndrome?
A gastroenterologist, a doctor who treats the digestive system, usually leads care for Ogilvie syndrome. A general surgeon, a doctor who operates on the belly, may help if surgery is needed. Most cases start in the hospital. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is Ogilvie syndrome?
Ogilvie syndrome is a rare condition of the colon, also called the large bowel. Another name is acute colonic pseudo-obstruction, or ACPO. The colon is often very wide, or dilated. Its muscles do not move waste along well. The symptoms look like a blockage, but nothing is physically blocking the colon.
It is not the same as chronic intestinal pseudo-obstruction, a similar but different disorder. Ogilvie syndrome is usually linked to another illness, an injury, or surgery. It most often happens in people who are in the hospital or a care facility.
Symptoms
Common symptoms include:
- Swelling of the belly, called distention, and bloating.
- Belly pain.
- Nausea and vomiting.
- A long history of constipation in some people.
Belly swelling usually builds over several days. It can also build within 24 hours. Fever, a very tender belly, and a high white blood cell count can occur. They are more common when the colon has a hole or loses blood flow.
A hole in the colon wall is called a perforation. Lost blood flow is called ischemia. Both are serious. A perforation is rare, found in only 1 to 3 percent of people with Ogilvie syndrome.
Causes and who gets it
Doctors do not fully understand the exact cause. It most often follows a serious illness or an operation.
The three most common linked problems are an injury without surgery, an infection, and heart disease. Pneumonia and sepsis, a severe blood infection, are the most common infections. Surgery on the belly, bones, nerves, urinary system, or heart has been linked to it.
Some medicines have been linked to it too. They include anticholinergics, amphetamines, steroids, and narcotics, which are strong pain medicines.
How doctors diagnose it
Doctors use your symptoms, your history, an exam, and tests. Symptoms alone cannot tell Ogilvie syndrome from a true blockage. So an x-ray of the belly is done to look for a blockage. It can show a colon that is wider than normal.
If gas and swelling are not in the whole colon, doctors may do a water-soluble enema or a CT scan. It matters to tell the two problems apart, because the treatments are different.
Treatment
Most people respond to conservative management, which means careful care without surgery. Doctors first check for signs of a perforation or ischemia. These signs need immediate medical care.
Conservative care can include:
- Treating the illness that set it off.
- No food or drink by mouth.
- Fluids through a vein to fix fluid and salt imbalances.
- A tube through the nose into the stomach to pull out swallowed air.
- A thin tube in the rectum to let gas and stool out.
- Stopping medicines that slow the bowel, such as opiates and anticholinergics. Follow your doctor's instructions and never stop a medicine on your own.
A medicine given through a vein has quickly lowered pressure in the colon in some people with Ogilvie syndrome who did not respond to conservative care. Some people need colonic decompression, which lowers pressure inside the colon. Decompression methods carry risks, including a perforation, and the problem can come back.
Surgery is rare. It is used when there are signs of a perforation or ischemia, or when other care has not worked. Surgery can carry serious risks, partly because of the illness behind it. Options include making an opening in the colon to let gas out, or removing part of it.
When to see a doctor
Call 911 or go to the emergency room if you have intense belly pain, especially with fever. A hole in the bowel can cause intense belly pain, fever, and sepsis.
If your belly swells, or you have bloating, nausea, or vomiting after an illness or surgery, tell your care team. If you are home, get medical care.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Most cases begin in the hospital. After you go home, this kind of doctor can help with follow-up and review your medicines. They can also coordinate care with specialists.
Common questions
Is Ogilvie syndrome dangerous?
Yes, it can be. The widened colon can lead to serious, life-threatening problems, such as a hole in the colon wall or lost blood flow. A hole in the colon wall is rare. Most people respond to conservative management.
Is Ogilvie syndrome the same as a bowel blockage?
No. The symptoms are almost the same, but nothing physically blocks the colon in Ogilvie syndrome. Doctors must tell the two apart, because the underlying problem and the treatments are different.
Can Ogilvie syndrome go away on its own?
Sometimes it can. Some cases go unrecognized and clear up without treatment. Still, it can cause serious problems if it is not found and treated, so do not wait it out.
Does Ogilvie syndrome need surgery?
Usually not. Most people respond to conservative management. Surgery is rare and is used when there are signs of a perforation or ischemia, or when other care has not worked.
