Figure 2 Diagram of the main diagnoses acquired during IOE. Angiodysplasia was the most frequent finding. Other findings were one Dieulafoy ulcer in the cecum (not-diagnosed during a previous colonoscopy). Three patients had a Meckel’s diverticulum and 3 patients had a large diverticulum in the ileum (n = 1) or jejunum (n = 2).
