Intestinal pseudo-obstruction is a condition in which there are symptoms of intestinal blockage without any physical signs of a blockage.
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
Irritable bowel syndrome (IBS) is the most commonly diagnosed disorder of the gastrointestinal tract in the United States. It accounts for about 30 percent of all referrals to gastroenterologists, and this condition contributes significantly to health care costs. It used to be a diagnosis of exclusion where numerous medical tests needed to be completed with negative results in order to finally make the diagnosis. Over the years, it has been determined that patients with IBS tend to experience specific symptoms, which have been summed up in diagnostic criteria by the gastroenterology community.
As a result of these Rome criteria, it is recommended that IBS be diagnosed according to these symptom-based criteria. Using these criteria along with outlined “alarm symptoms” has helped minimize the use of diagnostic testing that could have potential to unnecessarily place someone at risk for adverse risks or complications. The cause of IBS remains incompletely understood an...
