(redirected from hemorrhoidal cushions)

a·nal cushions

Stapled hemorrhoidopexy is done with a circular stapler device, which circumferentially removes the mucosa and submucosa above the hemorrhoidal cushions.

Routine ligation of all arteries in the rectal column may be unnecessary and ligation of only the visible hemorrhoidal cushions seems to be feasible.
