A group of chronic disorders that impair gastrointestinal motility, despite the absence of an actual obstruction. Symptoms include cramping and abdominal pain, malnutrition, nausea, and vomiting. Some forms of pseudoobstruction appear to be genetically inherited. Diagnosis is by observation of symptoms, measuring pressure in the GI tract, and microscopic examination of the bowels. There is no specific treatment for this disorder, although medications can be used to relieve specific symptoms. Special diets, and sometimes tube-feeding, are sometimes necessary. Surgery is rarely effective.
