title: [Clinical application of MSCT in diagnosis of intestinal obstruction].
abstract: OBJECTIVE
  To investigate the role of various multiple slice computed tomography (MSCT) and its reconstruction techniques in diagnosing intestinal obstruction (IO).
  
  
  METHODS
  419 cases diagnosed as IO by MSCT and proved by operations or follow up were analysed, retrospectively.
  
  
  RESULTS
  As to the presence diagnosis of IO, in all the patients, CT diagnosis was consistent with the final results, while X-ray plain film had an accuracy of only 60.5% (237/392). The causes of IO included adhesion 88.6% (117/132), neoplasm 98.2% (112/114), external or internal hernia 93.5% (43/46), intussusception 97.4% (37/38), inflammatory disease (including 7 cases paralytic ileus, 83.3%, 30/36), enterolith 88.5% (23/26), bowel torsion 90.9% (10/11), trauma 62.5% (5/8), ischemia 100% (6/6), congenital lesion (100%, 2/2). Total sensitivity of etiology diagnosis with CT was 92.8% (384/419), with accuracy, false positive and false negative to be 91.9% (385/419), 1.0% (4/419) and 7.2% (31/419), respectively.
  
  
  CONCLUSIONS
  MSCT can correctly diagnose the presence of the ileus, as well as can obviously enhance the accurate rate of diagnosis of its causes and characteristics, position, existence of close-loop and strangulation.
