title: [The contribution of capsule endoscopy to the diagnosis of small-bowel tumors in cases of obscure overt gastrointestinal bleeding].
abstract: BACKGROUND
  The source of obscure bleeding is usually located in the small bowel. The use of capsule endoscopy (CE) has changed the management of these patients.
  
  
  OBJECTIVE
  To review our experience with the diagnosis of small bowel tumors by CE in patients with obscure overt gastrointestinal bleeding.
  
  
  METHODS
  Retrospective analysis of CE examinations performed consecutively in two university-affiliated hospitals.
  
  
  RESULTS
  Among 156 patients who underwent CE examination (including 58 patients with obscure overt bleeding), five patients, all of whom presented with melena, were diagnosed as having a small bowel tumor. Three tumors were found in one patient (two ileal carcinoids and one ileal benign stromal tumor). A jejunal benign stromal tumor was diagnosed in two other patients by push enteroscopy. One of these was missed by a subsequent capsule endoscopy examination, and in the other, only active bleeding was detected by prior capsule endoscopy. In two patients, three small tumors were detected, beyond the reach of push enteroscopy, but surgical confirmation was not available. No tumors were found among patients in whom the indication for CE examination was not obscure overt bleeding.
  
  
  CONCLUSIONS
  The possibility of finding a small bowel tumor emphasizes the role of capsule endoscopy in patients with obscure overt gastrointestinal bleeding. Push enteroscopy should be performed when capsule endoscopy yields negative or only suspicious findings.
