Chronic intestinal pseudo-obstruction is the term applied to a heterogeneous group of functional motility disorders sharing a common clinical expression: signs and symptoms of bowel obstruction in absence of mechanical occlusion. It is caused by ineffective intestinal propulsion. The chronic form of intestinal pseudo-obstruction may be primary or secondary. Primary pseudo-obstruction or chronic idiopathic pseudo-obstruction (CIIP) defines a group of propulsive disorders having no recognized underlying diseases. This study presents four female patients, aged between 4 months to 7 years, and makes a review of the literature. The symptoms, very similar in three of them, were bilious vomiting, abdominal distention and constipation, alternating with diarrhea and malnutrition. The fourth patient, different from the others in the age of onset and evolution, only had severe constipation and abdominal bloating. The diagnostic was made by full thickness biopsies during laparotomy, getting specimens by mapping, at different heights of intestine and stomach. Samples were studied by optic and electronic microscopy and visceral myopathies were found. None of them had urinary disorders. Medical treatment consisted of total parental nutrition and/or enteral nutrition. Cisapride was not effective in the two patients who received it.
