Gastrointestinal bleeding is a common problem and represents a major cause of morbidity and mortality. Annual rates of approximately 125 episodes per 100,000 inhabitants are suggested by population-based studies from the 1960s and 1970s. In about 5% of patients with digestive blood loss, no bleeding site is identified after routine upper and lower endoscopy and small bowel X-ray series. In these cases, a small bowel origin of the bleeding has to be suspected. Many causes of intestinal bleeding have to be considered. However, before considering a small bowel origin, upper or lower gastrointestinal bleeding has to be excluded with certainty.
