Prospective evaluation of the long-term outcomes after deep small-bowel spiral enteroscopy in patients with obscure GI bleeding

In patients with obscure GI bleeding, deep small-bowel spiral enteroscopy is safe and effective in reducing the incidence of overt bleeding. An increase in hemoglobin values along with a decrease in blood transfusion requirement, need for iron supplementation, and need for additional therapeutic procedures were found over long-term follow-up.
