Unlike esophageal<unk> , rectal<unk>  are less prone to bleeding, are less serious when a bleed does occur, and are easier to treat because of the more accessible location. However, in some cases, rectal<unk>  can result in severe bleeding. Typically, treatment consists of addressing the underlying portal hypertension. Some treatments include portosystemic shunting, ligation, and under-running suturing. Insertion of a transjugular intrahepatic portosystemic shunt (TIPS) has been shown to alleviate<unk>  caused by portal hypertension. Successful treatment of portal hypertension that subsequently reduces<unk>  provides a confirmation of the initial diagnosis, allowing for a distinction between<unk>  and hemorrhoids, which would not have been alleviated by reduction of portal hypertension.
