Hemorrhoidal (anal) cushion

Anal cushion or hemorrhoidal cushion is part of the anal canal between the anal sphincter mescles and the rectum.

The function of the anal cushion is too seal stools when you are not next to the loo. When there is an urge to defecate the sphincter muscles will pull the feaces in and the anal cushion would fill with blood and expand and would create a seal and block the stools.

Most patients with internal hemorrhoids who opt for stapled hemorrhoidctomy should be aware that the anal cushion will be cut during stapled hemorhoidctomy and they would loose the sealing power and would only depend on anal sphicter muscles.
