title: Accuracy of community based video capsule endoscopy in patients undergoing follow up double balloon enteroscopy.
abstract: OBJECTIVE
  To determine the test characteristics of community based video capsule endoscopy (VCE) in patients undergoing sequential VCE and double balloon enteroscopy (DBE).
  
  
  METHODS
  Eighty-nine patients (34 females, 55 males, mean age 66) who underwent both VCE and DBE from 2008-2010 were retrospectively reviewed. Lesions detected at VCE were categorized. Capsule directed DBE followed and included 44 antegrade, 11 retrograde and 34 combined antegrade and retrograde procedures. Lesions detected were compared utilizing the McNemar's test.
  
  
  RESULTS
  Angioectasia detection with VCE was 25% and with DBE 35% (P < 0.03) with a calculated sensitivity and specificity of 58% and 93% respectively. Polyps were detected by VCE in 22% and in DBE 20%, (P = 0.6), with a sensitivity and specificity for VCE of 61% and 87%. Small bowel diverticula were only seen in 1% of VCE but in 12% of DBE patients (P < 0.002) with a calculated sensitivity and specificity of VCE of 9% and 100%.
  
  
  CONCLUSIONS
  VCE would be moderately sensitive and specific overall with considerable variation by lesion. Furthermore, VCE cannot be relied upon to diagnose small bowel diverticula.
