Diffuse idiopathic colonic varices characterized by lower gastrointestinal system bleeding

Abstract

Although colonic varices are rare, they usually occur secondary to portal hypertension. On the other hand, idiopathic colonic varices are quite rare entities and should be considered as a differential diagnosis in cases of lower gastrointestinal bleeding. A 45-year-old male patient was admitted to our hospital with recurrent rectal bleeding and severe anaemia. Four units of blood were transfused. Colonoscopy revealed submucosal varices throughout the entire colon. Studies to reveal portal hypertension gave no data about portal pathologies. Since there was no active bleeding during follow-ups in our clinic, the patient was discharged with conservative suggestions. Idiopathic colonic varices are rare entities, but they should be considered as a differential diagnosis in cases of rectal bleeding. A conservative approach is preferred, but in cases with active and unstoppable bleeding segmental or total colectomy should be the appropriate choice.
