(Colonic Ileus; Ogilvie’s Syndrome; Acute Colonic Pseudo-obstruction; Acute Nontoxic Megacolon)
DefinitionIn intestinal pseudo-obstruction, foods and liquids are unable to pass through the intestine, causing a build-up of food, fluid, and gas in all or part of the colon. The symptoms of this condition act like a mechanical bowel obstruction , but no blockage is found when doctors examine the intestine.

CausesIntestinal pseudo-obstruction is caused by problems with the muscles and nerves of the intestine.
Risk FactorsThe following factors are thought to increase the risk of developing intestinal pseudo-obstruction:
- Abdominal hemorrhage
- Intestinal ischemia (insufficient blood supply to the digestive system)
- Inflammation (eg, infection)
- Metabolic problems
- Fluid overload (eg, congestive heart failure )
- Other medical illnesses associated with pain
- Certain medications
SymptomsSymptoms of intestinal pseudo-obstruction may include:
- Stomach pain
- Reduction in bowel movements
- Loose stools
- Bladder problems
DiagnosisYou will be asked about your symptoms and medical history. A physical exam will be done.Your body fluids may be tested. This can be done with:
- Blood tests
- Urine tests
TreatmentTalk with your doctor about the best treatment plan for you. Treatment options include:
Nutritional SupportIV feeding may be necessary to help prevent malnutrition.
MedicationsYour doctor may prescribe antibiotics to help prevent bacterial infections due to your condition. In addition, medications can be used to treat muscle problems in the intestines. Changes in your medications may be made to eliminate some medications that can slow recovery from, or worsen, this condition.
SurgeryIn severe cases of intestinal pseudo-obstruction, surgery to remove part or your entire intestine may be necessary.
EndoscopyIf the colon does not resume normal function after conservative management, the pressure build-up in the colon can be relieved by removing the trapped air with a colonoscope .
PreventionMany cases of intestinal pseudo-obstruction cannot be prevented. But certain measures can be taken after surgery to help avoid the complication of intestinal pseudo-obstruction. These measures include:
- Early oral feeding
- Gum chewing
- Fluid restriction
- Medications that inhibit opioid receptors

Many medical groups felt that early exposure to certain foods like peanuts increased a child's risk of developing food allergies. However, newer research including this trial suggest that early exposure may actually decrease the risk of developing food allergies.
