Hemorrhoids
The term, "hemorrhoids" refers to groups of blood
vessels in the anorectal area which are present in everyone.
However, less than XX % become symptomatic from difficulties
with their hemorrhoids. There are two types of hemorrhoids:
internal and external. This distinction is important, because
of the possible symptoms and treatment alternatives. The division
is marked anatomically by the dentate line, which embryologically
delineates where skin-type structures meet with rectal lining
structures. Importantly, there are many nerve endings for
pain distal (beyond) to this line, where the external hemorrhoids
are, whereas proximal (in front) to this line, there are no
pain fibers.
Both types of hemorrhoids can bleed, thrombose (clot), and
prolapse. Normally, external hemorrhoids can be uncomfortable
and sometimes disabling when they thrombose. Internal hemorrhoidal
symptoms have been graded:
Grade 1: Bleeding
Grade 2: Prolapse, but reduce spontaneously
Grade 3: Prolapse, requiring manual reduction
Grade 4: Prolapse, unable to be reduced
Initial evaluation includes a history and physical examination.
In the history, your physician will ask you questions regarding
your symptoms, your diet, previous therapies and examinations.
An anoscopy (3-4 inch scope inserted through your anus) may
be performed to localize the problem or to determine if other
problems coexist.
A thrombosed external hemorrhoid may be associated with a
recent change in bowel habits. It will appear as a localized
swelling around the anus, the size of a pea or grape, which
may be blue or purple in color, and very tender. Pain is due
to the clot itself and due to swelling associated with this
process. If you are found to have an acutely thrombosed external
hemorrhoid, your physician may offer you a small office procedure
to remove the clot. Even without such a procedure, the clot
and the swelling will dissipate, however, often in the first
24-48 hours, the pain can be so intense that you may be unable
to complete your normal daily activity. A mild analgesic may
be prescribed. Perianal ("around" the anus) care
includes the avoidance of constipation, sitz baths (sitting
in warm water several times a day and after bowel movements),
and good hygiene. Despite the fact that you may have an open
wound in a 'dirty' area, it is amazing that the infection
and abscess formation are rare. A sequela of external hemorrhoidal
disease includes residual skin tags. These are harmless, but
may impair good hygiene.
Internal hemorrhoidal disease is managed dependant on symptoms.
If medical management is optimal, that is, you have soft bowel
movements without straining and have been compliant about
observing recommendations to avoid constipation, your physician
may offer several therapies to you. First and foremost, other
possible explanations must be excluded, including malignancy.
Therefore colonoscopy, or other visualization techniques must
first be performed to exclude such a possibility. If your
bleeding symptoms persist, ligation of the hemorrhoid using
a rubber band is an alternative. This highly effective office-based
technique applies a tight rubber ring around the hemorrhoid
to strangulate a small amount of tissue. Once the ring cuts
through the tissue, the ring and the tissue will fall off.
This technique produces a dull ache, because, there are no
true pain fibers in the area of the ligation. Complications
are rare, but can be life-threatening. Your physician will
discuss the complications and the signs that a complication
may be evolving with you. If your internal hemorrhoidal symptoms
are more complex, or are associated with external hemorrhoidal
symptoms as well, surgical removal of the hemorrhoids may
be warranted. A myriad of techniques may be used, including
injection and coagulation of the hemorrhoids, which results
in the shriveling of the hemorrhoids, removal with a surgical
scalpel, an ultrasound based scalpel, suture ligation, or
stapling of the lining. Your physician will discuss the advantages
and disadvantages of each of these possibilities. During the
post-operative period, it is important to care for yourself
by avoiding constipation, and continuing good perianal care.
Less than 5% of patients seeking a colorectal surgeon with
hemorrhoidal complaints need surgery. However, your physician
will speak with you and outline alternatives in evaluation
and treatment.
