Importance of second look endoscopy in patients of potential small bowel bleed : A prospective observational study

Previous prospective and retropesctive studies have revealed that, during evaluation for small bowel bleeding, 3.5 to ~20% have an attributable lesion within the reach of the upper and lower gastro-intestinal endoscope. We wanted to assess the prevalence of lesions causing GI bleeding, at second-look upper gastrointestinal endoscopy (UGIE) and/or Colonoscopy, that can avoid the necessity of performing small bowel evaluation (in form of enteroscopy and/or capsule endoscopy and/or CT-enterography) in patients presenting with Probable small bowel bleeding, either overt or occult.
