Overview

Angiodysplasia must be differentiated from other diseases that cause hematochezia, melena, and iron deficiency anemia , such as hemorrhoids, diverticular disease and colon cancer.

Differentiating Angiodysplasia from other Diseases

Angiodysplasia must be differentiated from diverticulitis, hemorrhoids, colon cancer, massive upper GI bleed and inflammatory bowel disease.
