Primary intestinal pseudo-obstruction; Acute colonic ileus; Colonic pseudo-obstruction; Idiopathic intestinal pseudo-obstruction; Ogilvie's syndrome; Chronic intestinal pseudo-obstruction
Causes, incidence, and risk factors
In primary intestinal pseudo-obstruction, the small or large intestines lose their ability to contract and push food, stool, and air through the gastrointestinal tract.
The condition can occur suddenly (acute) or over time (chronic). It may occur at any age, but is most common in children and the elderly. Because the cause is unknown, it is also called idiopathic intestinal pseudo-obstruction (idiopathic means occurring without reason).
Risk factors include:
Having cerebral palsy or other nervous system (neurologic) disorders
Staying in bed for long p...
Paralytic ileus; Intestinal volvulus; Bowel obstruction; Ileus; Pseudo-obstruction - intestinal; Colonic ileus
Abdominal fullness, gas
Signs and tests
While listening to the abdomen with a stethoscope, your health care provider may hear high-pitched bowel sounds at the onset of mechanical obstruction. If the obstruction has persisted for too long or the bowel has been significantly damaged, bowel sounds decrease, eventually becoming silent.
Early paralytic ileus is marked by decreased or absent bowel sounds.
Tests that show obstruction include:
Abdominal CT scan
Upper GI and small bowel series
Alternative Names Intestinal necrosis; Ischemic bowel; Dead bowel; Dead gut Treatment Treatment usually requires surgery. The section of intestine that has died is removed, and the healthy remaining ends of bowel reconnected. In some cases, a colostomy or ileostomy is necessary. A blockage of arteries supplying the intestine is corrected if possible. Support Groups Expectations (prognosis) Intestinal ischemia is a serious condition that can result in death if not treated promptly. The outlook depends on the cause. A good outcome may be achieved with prompt treatment. Complications Intestinal infarction may require a colostomy or ileostomy, either temporary or permanent. Peritonitis is common in such cases. Severe illness with fever and bloodstream infection ( sepsis ) can result. Calling your health care provider Call your health care provider if you have any severe abdominal pain.
