    Abstract:
    OBJECTIVE: To analyze and determine the clinical characteristics and diagnostic methods of chronic intestinal pseudo-obstruction(CIP). METHODS: We reviewed the medical records of all 23 patients who diagnosed with CIP in Peking Union Medical College Hospital from 1978 to 2000. RESULTS: Twenty three patients fulfilled the diagnostic criteria (9 male, 14 female, median age 50 years, range 4-75 years). The main symptoms at the presentation were abdominal distension(87%), pain(57%), diarrhea(65%), constipation(48%), vomiting(39%) and weight loss(83%). In this group of CIP patients, the abdominal distension was more common and serious than pain, presenting with diarrhea, weight loss and dismotility in esophagus and stomach. Bowel loops and visible peristaltic waves were seldom observed in the CIP patients. The plain film showed the multiple air-fluid levels (17/20, 85%) and generalized intestinal distention and air in colon. The abnormal findings on the barium contrast examination included intestinal dilation (19/23, 83%), weaken peristalses or/and prolongation of transit time (74%) without mechanical lesions. The pseudo-obstruction involved the small intestine (83%) and colon (39%) that determined according to the radiographic features, abnormal gastrointestinal motor functions, findings of endoscopic examination and laparotomy. Eighteen cases were chronic idiopathic intestinal pseudo-obstruction (1 familial myopathy), 5 were secondary to CTD. CONCLUSIONS: Comparison with the typical mechanical obstruction, the presentations of CIP have some relatively characteristics. The clinical diagnosis of CIP can be confirmed on the basis of typical clinical symptoms and radiographic features, abnormal gastrointestinal motility.
