The diagnosis of Meckel's diverticulum by small bowel enema in the investigation of obscure intestinal bleeding.

A diagnosis of Meckel's diverticulum was made by small bowel enema in a patient suffering from occult bleeding. Meckel's diverticulum is rarely seen on the standard small bowel follow-through and is unreliably detected by isotope studies in the adult. In the investigation of intestinal bleeding the diagnosis may be overlooked unless a small bowel enema is performed. It is recommended that it be performed before arteriography if colonoscopy is normal.
