What is Chronic Intestinal Pseudo-Obstruction

Chronic Intestinal Pseudo-Obstruction (CIPO) is a rare, severe motility disorder where the digestive tract fails to move food, gas, and liquid through the intestines despite the absence of a physical blockage. It is characterized by recurring symptoms of bowel obstruction, such as severe abdominal pain, bloating, and vomiting, which significantly impact a patient’s ability to maintain nutrition.

What causes Chronic Intestinal Pseudo-Obstruction?

The underlying mechanism of Chronic Intestinal Pseudo-Obstruction involves a failure in the coordinated contractions (peristalsis) of the smooth muscles of the gastrointestinal tract. This can be caused by damage to the nerves that control these muscles (neuropathic) or a primary defect in the muscle cells themselves (myopathic). In some cases, Chronic Intestinal Pseudo-Obstruction is a secondary result of other systemic diseases, such as scleroderma or amyloidosis, while in others, it remains idiopathic (unknown cause).

How is this condition classified?

Clinicians typically categorize Chronic Intestinal Pseudo-Obstruction based on the origin of the dysfunction and whether it is a lifelong condition or an acquired one:

• Primary CIPO: Often genetic or developmental, involving abnormalities in the enteric nervous system or intestinal smooth muscle.


• Secondary CIPO: Occurs due to external factors like connective tissue disorders, endocrine conditions, or paraneoplastic syndromes.

Who is affected by Chronic Intestinal Pseudo-Obstruction?

Chronic Intestinal Pseudo-Obstruction is exceptionally rare, with an estimated prevalence between 1 and 10 per 100,000 individuals, though exact figures are difficult to confirm due to underdiagnosis. It can affect individuals of any age, from infants to the elderly. While the 9 members of the DiseaseMaps.org community represent a small sample, their experiences highlight the diagnostic journey often required to identify this condition. Unlike mechanical obstructions, Chronic Intestinal Pseudo-Obstruction does not show a physical "kink" or mass on standard imaging, which is a key clinical differentiator.
