Evaluation of patients with hereditary hemorrhagic telangiectasia with video capsule endoscopy: a single-center prospective study

Abstract

Small-bowel telangiectases were seen in the majority of patients with HHT and were evenly distributed throughout the small bowel. Telangiectases were observed in only a minority of patients who did not have HHT. Actively bleeding small-bowel telangiectases were located in the proximal and mid-small bowel in patients with HHT, all within reach of an enteroscope. We propose a cutoff point of at least five gastrointestinal telangiectases to support a diagnosis of HHT.
