The chronic intestinal pseudo - obstruction clinical features and diagnosis

Chronic intestinal pseudo - obstruction (CIP) is a gut muscle neuropathy caused by intestinal motility disorders, Performance for recurrent or persistent intestinal obstruction and no evidence of mechanical obstruction is a rare disease. In order to analyze the performance of the CIP characteristic clinical and diagnostic methods. We Beijing Union Medical College Hospital from November 1978 to December 2000 diagnosis of 23 cases of CIP patient's clinical data are summarized and analyzed.
The CIP diagnostic criteria are: (1) obstruction on the clinical signs and symptoms (2) abdominal plain film obstruction confirmed the existence (3) the inspection clearly ruled out mechanical ileus (4) gastrointestinal imaging examination revealed dilated intestine, or bowel movements slowed, disappeared or (5) Determination of pressure digestive tract abnormalities, gastrointestinal transit time was significantly longer.
Results showed that 23 cases of CIP patients men nine cases, female 14 cases, aged 4 to 75 years (median age 50 years). Course 1 month to 20 years (median 3). Seven cases of intestinal obstruction for intermittent seizures. CIP main symptoms are abdominal distension in patients with: (87%), abdominal pain (56.52%), diarrhea (65.22%), constipation (47.83%), vomiting (39.13%) and weight loss (82.61 percent). Prominent in this group patients with abdominal distention and abdominal pain were relatively light, with diarrhea, weight decreased significantly and the other parts of digestive tract abnormalities dynamic performance. CIP abdominal is most common in patients with abdominal signs (65.22%), seven cases there intestinal type (30.43%), 3 cases have peristalsis wave (13.04%); obstruction in the presence of sound normal (30.43%) or weakened (47.83%), the rare signs of mechanical intestinal obstruction. 85% of patients with intestinal obstruction attack in the abdominal plain film of gas on the existence of a number of plane, we can see that universal expansion intestine, colon plot gas (65%). Upper gastrointestinal barium angiography showed marked expansion intestine (82.61%), peristalsis slow down and disappear (73.91%), all patients found no evidence of mechanical obstruction. Some patients with lower gastrointestinal dynamic, anorectal dysfunction, gastrointestinal through prolonged. Major intestinal lesions involved (82.61%), colon (39.13%). Four cases accepted laparotomy and surgery. 18 cases of chronic idiopathic intestinal pseudo - obstruction, including one case of the familial visceral myopathy; five cases secondary to connective tissue disease.
