Does any lower gastrointestinal bleeding in patients suffering from hereditary hemorrhagic telangiectasia (Osler–Weber–Rendu) necessitate a full colonic visualization?

Background Hereditary hemorrhagic telangiectasia (HHT) (the Osler–Weber–Rendu syndrome) is a rare autosomal dominant disease characterized by telangiectasias and arteriovenous malformations of the upper and lower respiratory tract, gastrointestinal tract, skin and central nervous system. Several previous reports have documented the appearance of a concomitant neoplasm in patients with this syndrome.
