During stapled hemorrhoidectomy, the arterial blood vessels that travel within
the expanded hemorrhoidal tissue and feed the hemorrhoidal vessels are cut,
thereby reducing the blood flow to the hemorrhoidal vessels and reducing the
size of the hemorrhoids.
During the healing of the cut tissues around the
staples, scar tissue forms, and this scar tissue anchors the hemorrhoidal
cushions in their normal position higher in the anal canal. The staples are
needed only until the tissue heals.
They then fall off and pass in the stool
unnoticed after several weeks. Stapled hemorrhoidectomy is designed primarily to
treat internal hemorrhoids, but if external hemorrhoids are present, they may be
reduced as well.
Stapled hemorrhoidectomy is faster than traditional hemorrhoidectomy, taking
approximately 30 minutes. It is associated with much less pain than traditional
hemorrhoidectomy and patients usually return earlier to work. Patients often
sense a fullness or pressure within the rectum as if they need to defecate, but
this usually resolves within several days.
The risks of stapled hemorrhoidectomy
include bleeding, infection, anal fissuring (tearing of the lining of the anal
canal), narrowing of the anal or rectal wall due to scarring, persistence of
internal or external hemorrhoids, and, rarely, trauma to the rectal wall.
Stapled hemorrhoidectomy may be used to treat patients who have both
internal and external hemorrhoids; however, it also is an option to
combine a stapled hemorrhoidectomy to treat the internal hemorrhoids and
a simple resection of the external hemorrhoids.
