title: [Diagnostic value of high resolution sonography in Crohn's disease and ulcerative colitis].
abstract: OBJECTIVE
  To evaluate the diagnostic accuracy of high resolution sonography in patients with inflammatory bowel disease (MICI).
  
  
  METHODS
  In patients with Crohn's disease (n = 48), ulcerative colitis (n = 23), indeterminate colitis (n = 3), inflammatory (n = 21) and non-inflammatory (n = 23) controls, high resolution sonography was performed and compared to colonoscopy (+/- retrograde ileoscopy) and/or baryum studies of the small bowel and the colon.
  
  
  RESULTS
  Diagnosis of intestinal inflammation or not was correct in 69/74 MICI patients (sensitivity: 94.4%, specificity: 66.7%, global accuracy: 93.2%). Segment location was accurate in 58/74 (sensitivity: 80.3%, specificity: 66.7%, global accuracy: 79.7), more frequently in Crohn's disease, than in ulcerative colitis. Five out of six complications of Crohn's disease were diagnosed. In Crohn's disease, the method was more accurate in case of colonic or ileocolonic involvement.
  
  
  CONCLUSIONS
  High resolution sonography is a reliable diagnostic tool for the detection of intestinal inflammation and related complications in MICI. In can be of value in the follow-up and seems particularly interesting in the case of temporary contraindication of invasive methods.
