Novasure Endometrial Ablation
Endometrial ablation (often spelled as oblation, or oblasion, or
ablasion) is the process of destroying endometrium, the inner lining
of the uterus, in order to solve a problem such as heavy bleeding,
pain, exhaustion and so on. Novasure type of endometrial ablation
is an electrode which is placed in the cervix, and which emits a
short burst of radiofrequency
energy, no longer than 90 seconds. Who Is A Good Candidate For Novasure Endometrial Ablation?
You will be a good candidate if all of the following indications
are met:
you are not yet in menopause,
you have menorrhagia (excessive
bleeding),
the causes of menorrhagia
are benign, and
you have completed your childbearing.
Contraindications for Novasure Endometrial Ablation
Pregnancy or a woman who wants to become pregnant in the future.
In some cases, not the entire endometrium is destroyed, or even
if it is, it may develop again, which makes it possible for the
fertilized egg to get implanted. Such pregnacies must be terminated,
since nobody knows what to expect, even if such a pregnancy were
carried out to a full term.
Known or suspected uterine
cancer (endometrial carcinoma), or a pre-malignant condition
such as unresolved adenomatours hyperplasia.
Weakness
of the myometrium, maybe as a result of previous classical
cesarean section or transmural myomectomy.
Active
vaginal or urinary tract infection, such as cervicitis, vaginitis,
endometritis, salpingitis, or cystitis.
A patient with an intrauterine
device (UID) in place.
A patient with a uterine
cavity length less than 4 cm. The minimum length of the electrode
array is 4 cm. Treatment of a uterine cavity with a length less
than 4 cm will result in thermal injury to the endocervical canal.
A patient with active
pelvic inflammatory disease.
How Novasure Endometrial Ablation Works
Novasure
consists of an electrode with a sheath at the end; in the beginning
of the procedure, the sheath is placed through the cervix. The electrode
then expands and conforms to the shape of the uterine cavity. The
device tests whether there is any rupture of the cavity and will
not turn on if there is one. (As a safety measure, the device will
turn itself off if 50 ohms of resistance occurs.) Next, a small
quantity of CO2 inflates the uterus so that the device is placed
properly. If everything is OK, a short burst of radiofrequency energy,
for no more than 90 seconds, destroys the endometrium, and the whole
procedure lasts for less than 5 minutes. The device will also remove
the desiccated issue from the cavity. Most patients can go home
within an hour of the procedure.
Besides speed, the main advantage of Novasure Endometrial Ablation
is that there is no need to prepare the uterus with expensive
or dangerous drugs such as Lupron Depot. Lupron not only costs
$400 per shot, but has side effects such
as hot flushes, sweats, effectively, introducing a termporary
menopause.
Novasure
endometrial ablation can be executed at any time of the woman's
menstrual cycle.
Types of Anesthesia for Novasure Endometrial Ablation
Usually, for Novasure only local anesthesia and sedation are needed,
although epidural and general anesthesia are also an option in certain
cases. With other types of ablation, cramps are to be expected and
even feared, but with Novasure, there are cases of women playing competetive
tennis matches the same weekend.
Practical Contraindications for Novasure Endometrial
Ablation
The uterus has to be of fairly regular shape. Fibroids or large
polyps should be done away with in some other way before Novasure
could be applied. Actually, Novasure can be used even if there are
polyps up to 2 cm large, and it can be even used to treat fibroids
if they do not distort the shape of the cavity.
If
the wall of the uterus is too thin, this type of ablation should
also be ruled out.
As
with all other types of ablation, if you want more children,
this is not for you. After ablation, you should best be under
some kind of contraception as there is a possibility of getting
pregnant. As remote as it is, it is best it didn't happen, since
most of the endometrium -- the very tissue that your eventual
baby would be linked to under normal curcumstances -- is almost
all dead ("flamed up" in the case
of Novasure, "boiled" with thermal balloon and so on, depending
on the device used).
Other
Methods To Treat Excessive Uterine Bleeding Due To Benign Causes
If you go to the medical doctor to help you combat
excessive uterine bleeding, the drug therapy will be the first
step. Failing that, a Dilatation and Curettage (D&C) will
be next, as the first surgical step. After, that it may be
a choice between hysteroscopic endometrial ablation, thermal
endometrial ablation, laser
ablation,
electrosurgical
technique (roller ball or barrel),
Radio frequency ablation, Microwave ablation, and Cryo ablation. Failing
all that, hysterectomy
remains as the final choice.
Of
course, there are many other ways to combat
excessive uterine bleeding, please see the main energy
healing page on this site for a list of possible alternatives.
The Effects of Novasure Endometrial Ablation
<> In
tests that led to the approval of Novasure by the FDA, 93% of women
were satisfied with the outcome of the ablation within one year
and after 3 years, 44% of the women were amenorrheic. In other
words, this is comparable and even marginally better than other
types of ablation. However, the same objections apply to Novasure
as to any other type of ablation -- there can be watery and not
so watery discharges for weeks after the procedure, and only after
3-6 months will you be able to tell whether it all made sense
or not. For a small number of patients, all this will only prolongue
their route towards hysterectomy.)
