Anal Warts
What are anal warts?
Anal warts (also called "condyloma acuminata")
are a relatively common and bothersome condition that affects
the area around the anus. They may also affect the skin
of the genital area. They first appear as tiny blemishes,
perhaps as small as the head of a pin, and may grow larger
than the size of a pea. Usually, they do not cause pain
or discomfort to afflicted individuals. As a result, patients
may be unaware that the warts are present.
Where do these warts come from?
They are thought to be caused by the human papilloma virus
which is relatively contagious. The virus can be transmitted
from person to person, almost always by direct contact.
Do these warts always need to be removed?
Yes. If they are not removed, the warts generally grow larger
and become more and more numerous. In addition, there is
evidence that these warts can become cancerous if left untreated
for a long time.
What treatments are available?
If warts are very small and are located only on the skin
around the anus, they can be treated with medications, which
are applied directly to the surface of the warts. This method,
while relatively simple in concept, must be carried out
with great care and precision by a physician to prevent
injury to the normal skin surrounding the warts. This method
usually requires several applications performed at various
intervals over several weeks.
Another form of treatment involves more rapid destruction
of the warts using electrical cautery, surgical removal
or a combination of the two. Laser surgery may also be used
but has no advantage over other treatments. These procedures
provide immediate results but must be performed using either
a local anesthetic - such as novocaine - or a general or
spinal anesthetic, depending on the number and exact location
of warts being treated.
Warts inside the anal canal usually are not suitable for
treatment by medications, and in most cases need to be treated
by cauterization or surgical removal.
Must I be hospitalized for treatment?
No. Almost always, the cautery and excision technique can
be performed on an outpatient basis, and the patient can
go home after the procedure.
How much time will I lose from work after a cautery
treatment?
This depends on each individual situation and the extensiveness
of warts removed. Most people are moderately uncomfortable
for a few days after treatment, and pain medication may
be prescribed. Depending on the extent of the disease, some
people return to work the next day, while others may remain
out of work for several days.
Will a single treatment cure the problem?
Not in most cases, unfortunately. Even with the cautery
and surgical treatments that immediately destroy existing
warts, many patients develop new warts after treatment.
This occurs because viruses that cause the warts can live
concealed in tissues that appear normal for up to six months
or longer before another wart develops. New warts will often
develop from the virus that was already present in the tissue,
but these are not recurrences of warts already treated.
As new warts develop, they usually can be treated in the
physician's office, using either a chemical solution or
the electrical cautery procedure. These treatments are performed
every few weeks initially, then less frequently as new warts
become smaller and less numerous.
Sometimes new warts develop so rapidly that office treatment
would be quite uncomfortable. In these situations, a second
and occasionally third outpatient surgical visit may be
recommended.
How long is treatment usually continued?
Follow-up visits are necessary for some months after the
last wart is observed to be certain that no more warts occur
from viruses living in the cells of skin.
What can be done to avoid getting these warts again?
In some cases, warts may recur repeatedly after successful
removal, since the virus that causes the warts often persists
in a dormant state in body tissues. Following are tips to
avoid recurrence and reinfection:
Continue observation for several months after the last wart
has been spotted to improve the chances that both the warts
and the underlying virus that causes them have been eliminated.
Abstain from sexual contact with individuals who have anal
(or genital) warts. Since many individuals may be unaware
that they suffer from this condition, sexual abstinence
or limiting sexual contact to marriage relationships will
reduce your potential exposure to the contagious virus that
causes these warts. As a precaution, sexual partners ought
to be checked, even if they have no symptoms.
