Fibroid Embolization - A New Treatment
Option
Fibroids are common, benign growths of the muscle wall of the
uterus. About 30% of women will have fibroids during their lifetime,
but 80% of those women have no symptoms and, therefore, need no
treatment. For women with uterine fibroids that cause bothersome
symptoms, a number of treatments options are available. While
some doctors still recommend hysterectomy as a first option for
women with bothersome uterine fibroids, we find that this is rarely
necessary. Removal of just the fibroids, called myomectomy, can
almost always be performed. Myomectomy may be performed through
a bikini incision, or through the navel with the laparoscope.
When the fibroid is within the uterine cavity, a telescope called
a hysteroscope, can be placed through the cervix into the uterus.
A special attachment to the telescope can then be used to shave
the fibroid out of the cavity. Both laparoscopic and
hysteroscopic surgery are performed as outpatient surgery with
quick recovery.
Recently, a technique developed in France, called uterine artery
embolization, has been used to treat women with fibroids in the
United States. This non-surgical technique utilizes a very small
tube that is inserted into an artery in the groin and passed directly
into the main vessels feeding the uterus and associated fibroids.
Once this tube, or catheter, is in place, very small pellets of
polyvinyl alcohol are pushed through the catheter and into the
vessels, blocking off the blood flow to the uterus. It appears
that fibroids need a greater amount of blood flow than normal
uterine muscle. After the embolization procedure leads
to a loss of blood supply, the lack of oxygen to the fibroid cells
causes them to die off. The cells release biochemicals
into the surrounding area that cause a fair amount of discomfort
during the first few days after the procedure. Most women stay
in the hospital overnight in order to receive pain medication.
However, the majority of women go home the next day and can expect
reasonable recovery in 1-2 weeks.
Without a blood supply, the fibroids will begin to shrink. After
a few months, most studies have shown about a 40% reduction in
size of the fibroids. The best results have been found in women
who have bleeding from the fibroids as their most bothersome symptom. Almost
all of these women are able to avoid hysterectomy.
This procedure is a relatively new application of an established
technique. Therefore, while long-term results are expected to
be good, we do not have definitive results as yet. Some fibroids
do not respond well to this treatment, specifically fibroids that
attach to the uterus with a stalk, called pedunculated fibroids.
Often, the stalk will wither away, leaving the fibroid free to
wander about in the abdomen or inside the uterine cavity.
One potential problem is that some of the pellets have been found
to spread to the vessels feeding the ovary. As a result, about
5-10% of women will have the blood supply to the ovary decreased
enough to lead to premature menopause. The procedure has not been
commonly used in women who wish to get pregnant, again because
we do not know the long-term effects. Few women who have had embolization
and attempted pregnancy have been studied. Therefore, questions
regarding the strength of the uterine wall after embolization
and the ability of the uterus to withstand the forces of pregnancy
and childbirth have not been adequately answered.
However, we feel this procedure does have a place in the treatment
options we offer women with fibroids. Women who have completed
their families and who have large fibroids that primarily cause
bleeding may be excellent candidates for this procedure. Embolization
is performed in the hospital by an interventional radiologist.
If you are interested in this procedure, ask us about it. If embolization
is appropriate for you, we can refer you to an expert in the field.
Laparoscopic
Supracervical Hysterectomy
As always, we strive to stay on the cutting edge of developments
in gynecology. While we pride ourselves in performing hysterectomies
usually as a last resort to gynecologic problems, the operation
is sometimes necessary and appropriate. Our practice has a superb
reputation for gynecologic surgery in general, and laparoscopic
surgery specifically. We have been performing operative laparoscopic
surgery since 1987 and laparoscopic hysterectomies since 1993.
Recently, new instruments have been developed that allow a laparoscopic
procedure to be performed that previously was difficult and tedious.
This procedure, laparoscopic supracervical hysterectomy, differs
from standard laparoscopic hysterectomy in that the cervix is
retained in the woman's body, while the uterus (and tubes and
ovaries, if necessary or desired) is detached and removed through
small (one inch) incisions near the pubic hairline. The instrument
that makes this surgery feasible is called an electronic morcellator.
It is able to cut the uterus into small pieces so that the tissue
can be removed through these small incisions.
There is much debate as to whether there is any benefit to not
removing the cervix. The proponents of supracervical hysterectomy
suggest that bladder and sexual function are better preserved
with this operation because the nerves running to the bladder
and cervix are not disturbed if the cervix is left in place. In
addition, proponents feel that healing and recovery are faster
because there are not any stitches in the vagina that need to
heal. However, studies have shown conflicting results, and
it is not clear if these benefits truly exist. Ater supracervical
hysterectomy, it is important to continue to have Pap smears yearly.
However, pap smears are still a good idea every few years even
if the cervix has been removed, in that the test is able to find
vaginal cancer.
We now have extensive experience performing laparoscopic supracervical
hysterectomies and our own patient’s experience has been
very favorable. We find that postoperative discomfort is less
and healing is faster, and overall recovery is shorter than with
total laparoscopic hysterectomy. There are indications and reasons
for each procedure, and we discuss these with each patient who
needs a hysterectomy before surgery.
A
New Procedure For Incontinence - TVT
The tension-free vaginal tape procedure, or TVT, is a new procedure
first developed in Sweden in 1995. This procedure uses a
synthetic tape to form a hammock under the urethra that bolsters
it when you laugh, cough, exercise, or strain in any other way.
This procedure has been performed on over 150,000 women in Europe
and 20,000 in the United States, and the initial results are excellent. The
success rate so far is 85%. Surgery takes about 30 minutes and
may be performed with local or epidural anesthesia. Most women
can leave the hospital within a few hours and can urinate without
problems immediately after surgery.
The TVT procedure is performed through a small incision in the
vagina directly below the urethra. A loose hammock is made
beneath the urethra, and the ends of the hammock are pulled up
through two very small (1/2 inch) incisions made side by side
in the skin just above the pubic bone. The tape is carried
up to the abdominal wall with an instrument. Once the tape
is placed properly below the urethra the incisions on the skin’s
surface are closed.
Recovery is very rapid following TVT. The small incisions, the
one in the vagina and the two above the pubic bone, only cause
mild discomfort for a few days. Since the surgery can be performed
under local or epidural anesthesia with mild sedation, there is
none of the grogginess people sometimes feel after general anesthesia.
Our patients are usually walking around within a few hours and
go home from the hospital shortly thereafter.
The advantages of this to women who leak are obvious. We
finally have a minimally invasive procedure that can be done on
an outpatient basis with very good success and very little pain
or hassle. We have been very impressed with the results in our
own practice. Our youngest patients have been in their 30's,
our oldest are in their 90's. Most women are back to normal
activity in 1 week. However, it is necessary to limit lifting
to 5lbs. or less for 8 weeks. Patients typically return
to work in 1 to 2 weeks. If you think you could benefit
from this procedure please make an appointment with either Drs.
Rosenman or Parker.
