General Discussion

Intestinal pseudoobstruction is a digestive disorder that may be present at birth. The intestinal walls are unable to contract normally (hypomotility) to generate wave-like (peristaltic) motion. This condition resembles a true obstruction, but no such blockage exists. Abdominal pain, vomiting, diarrhea, constipation, malabsorption of nutrients leading to weight loss and/or failure to thrive, are signal signs. Enlargement of various parts of the small intestine or bowel also occur.

There are two kinds of Intestinal pseudoobstruction, depending on the source of the failure of the gastrointestinal tract. If the problem is abnormal functioning of the nerves of the abdominal wall leading to non-synchronized contractions, then the episode is classified as neurogenic and the disorder is known as neuropathic pseudoobstruction. If the functional failure can be traced to weak or absent contractions of the muscle itself, then it is classified as myogenic and the disorder is known as myopathic pseudoobstruction.
