Answer

Anorectal varices are common in patients with portal hypertension. [11] Varices occur in the midrectum, at connections between the portal system and the middle and inferior rectal veins. Varices occur more frequently in patients who are noncirrhotic, and they rarely bleed. Treatment is usually directed at the underlying portal hypertension. Emergent control of bleeding can be obtained with suture ligation. Portosystemic shunts and transjugular intrahepatic portosystemic shunts (TIPS) have been used to control hypertension and thus, the bleeding. [12]
