Varices Colónicas Idiopáticas.

Una Inusual Causa de Hemorragia Digestiva Baja.

Abstract

Colonic varices are an infrequent entity. They are usually detected by colonoscopy and in most cases, they are associated with portal hypertension. (1) They have an incidence of approximate 0.07% and are an exceptional cause of recurrent lower gastrointestinal bleeding. (2)

Those venous malformations whose etiopathogenesis is due to a congenital vascular disease are considered idiopathic. They are extremely rare, more common in men, with a mean age at diagnosis at 41 years. They have a major family association, being pancolonic more frequently in these patients than in non-idiopathic cases. (3)

We present a case of idiopathic colonic varices in a 16-year-old female patient presenting with lower gastrointestinal bleeding.

The aim of this work is to evaluate the behavior of a very peculiar pathology and to analyze the literature related to the subject.
