[Management of anorectal bleeding].

Management of anorectal bleeding. Anorectal bleeding is a common reason for consultation in general medical practice. The ano-rectal origin is suspected on the characteristics of the bleeding which is often scant and bright red color. Medical history and clinical examination alone are often sufficient to make a diagnosis, since the main causes are hemorrhoids and anal fissure. On the other hand, the estimated risk of anorectal tumours in patients with ano-rectal bleeding has been reported in about 10%. Colonoscopy is therefore necessary at the slightest diagnostic doubt and, anyway, in all patients aged over 45 years.
