CE was normal in 23.2 percent and was able to find lesions in 76.8 percent of the studies. Gastrointestinal bleeding, followed by iron deficiency anemia were the indications associated with the higher rates of positive findings during CE. Conclusions: Gastrointestinal bleeding and iron deficiency anemia were the indications that obtained the best diagnostic y ield for CE.
