The
commonest investigations, which are carried out, are
CBC, Thyroid profile and Sonography of pelvis. Sonography
will identify a bulky uterus, fibroids, adenomyosis
and give information on the thickness of the lining
of the womb.
In some cases a Hysteroscopy and Dilatation & Curettage
(D&C) is required. This is a day care procedure,
which is done for both diagnosis & treatment. Hysteroscopy
involves looking inside the womb with a telescope and
is particularly useful to identify polyps. D&C involves
scraping of the lining of the womb. The lining is then
sent for Histopathological Testing. Outcome of the reports
then enable us to plan the treatment.
Various forms of medication are used in management of
DUB.
1. Non-hormonal Drugs – These are usually taken
during the menses and help to reduce the amount of blood
loss from the uterus.
2. Hormonal Drugs – Progestogens and combined
oral contraceptive pills are used commonly in women
to manage DUB.
The above forms of medical treatments are effective
but the benefit may not last for very long. In such
situations the patient will require alternative treatment.
In present times modern modalities are available. Those
are simple, safe, effective and are day care procedures
that do not require even one night stay in the hospital.
LNG-IUS (Levonorgestrel Intrauterine
system)
This is a T shaped intra uterine system that is loaded
with Levonorgestrel. It releases 20 micrograms of Levonorgestrel
daily in the uterine cavity thereby leading to decidualization
followed by atrophy of the endometrium. It has a life
of 5 years and cost about Rs 8000/- It is used very
effectively in the management of DUB. It is inserted
at the time of a diagnostic hysteroscopy and curettage.
The entire procedure is done under general anesthesia,
takes about less than half an hour and the patient is
able to go home on the same day. This procedure can
avoid hysterectomy in 70-80% cases of DUB. An important
pre-requisite is that the endometrial cavity should
be uniform. An added advsntage of LNG-IUS is that it
is an effective contraceptive and the menstrual blood
loss reduces considerably.
Thermal Balloon Ablation
(TBA).
This is a silicone catheter that is connected to a central
heating unit. The balloon is inserted into the uterine
cavity, inflated to a presuure of 160 – 180 and
then heated to a temperature of 87 dergrees centigrade
fro 8 minutes. It leads to thermal ablation of the endometrium.
The procedure can be done under Intravenus sedation
and local anesthesia or general anesthesia. The operation
time is approximately 30 minutes and patient is able
to go home on the same day. A success rate of 90% over
three years and a long term success rate of 80% have
been reported. The randomized control trials comparing
LNG-IUS and TBA have reported similar results for both
procedures. The only tumbling block in providing this
state of the art technology for the treatment of DUB
is the formidable cost of the balloon. But one can definitely
offset it against the cost of the three day hospital
stay and loss of working days when recuperating from
major surgery.
Trans cervical resection
of the endometrium.
This is electrosurgical resection of the endometrium
with a loop under hysteroscopic vision. This procedure
too is day care but under certain circumstances can
require one night stay in the hospital. It is done under
general anesthesia. the procedure has a longer learning
curve. It is an acceptable treatment for DUB with a
long term success of 80%.
Hysterectomy
is still the last answer for DUB, and one of the commonest
surgeries performed by the gynecologist. Breakthrough
advances have taken place in vessel sealing i.e. hemostatic
devices that are used during laparoscopic surgery. The
optics have also improved dramatically over the years.
Therefore it may not be too long before hysterectomy
is done laparoscopically and patient is discharged on
the same day.
Conventional hysterectomy (vaginal & abdominal)
involves minimum hospital stay of two nights and three
days, average is three nights and four days. It is still
a popular and acceptable method, which is widely offered
by most gynecologists.
Conclusion
In modern times women need not be drained with DUB
and need not have a radical hysterectomy. The scientific
and judicial use of modern technology i.e. LNG-IUS,
TBA and minimally invasive surgery can bring relief
to millions of women with DUB; and this can be done
in just one afternoon. |
