title: Capsule endoscopy in obscure gastrointestinal bleeding--an Indian experience.
abstract: BACKGROUND
  Obscure gastrointestinal bleeding (OGIB) is a common indication for capsule endoscopy (CE). Reports on diagnostic yield of CE in this situation show a wide variation. We evaluated the diagnostic yield and clinical impact of CE in patients with OGIB.
  
  
  METHODS
  We reviewed the medical records of patients with OGIB who underwent CE at our institution between June 2002 and October 2005.
  
  
  RESULTS
  154 patients (mean age 47 [SD 17] years; 117 men), including 74 with overt OGIB and 80 with occult OGIB, underwent CE. CE yielded positive findings in 57 of 74 patients (77%) with overt OGIB and 22 of 80 (27%) of those with occult OGIB (p < 0.0001); the overall positive diagnostic yield was 52%. NSAID-induced lesions (15%), angiodysplasias (14%) and aphthous ulcers (12%) were the most frequent findings. CE helped in planning further management in 79% of patients with overt OGIB and 26% of those with occult OGIB.
  
  
  CONCLUSIONS
  CE is a useful diagnostic technique in patients with OGIB, especially those with overt OGIB.
