Why me?? Etiopathology: -of Endometriosis –A nightmare for
me. I was scolded by many of my pts in
50 yrs of practice for inability to control her beningn diseases(endometriosis)
. At last they all visited my granddaughters clinic who are MD FRCS FRCOG, FACOG by the age of 6 yrs and
have received several Nobel prizes for research on Corruption in India. Now
they are engaged in why and How endometriosis occurs in a healthy woman?? Why
& Why me?? Back to the problem of Endoemtrioms:- The main problem with
endometriosis is that it cannot be imaged as easily as myoma (non-invasive
procedure) but both the diseases are now considered as end result of aberrant
aromatase activity leading to increase in active estrogen.
There can be aberrations in
A) Aromatase activity and that of B)
17-β-hydroxysteroid dehydrogenase type 1 and type 2 enzyme (17-β-HSD)
activities.
[). Aromatase converts steroid
precursors to active estrogens. Normal endometrial tissue does not exhibit
aromatase enzyme activity. But it is seen in abundance in leiomyoma-- 90%
cases.]
In endometriosis: - 1) Aberrant aromatase
activity and 2) Deficiency of 17-β-HSD (type 2) (in normal endometrial this
enzyme converts active estrogen to inactive estrogen form)
In Myoma:
There is increased activity of17-β-HSD type 1--so inactive estrogen is
converted more into active estrogens. There is reversal of activity of 17-β-HSD
so that more active oestrogen is formed. This leads to increased uterine
peristalsis- interfering with nidation. If we believe that genetic cause and
resultant enzyme disorder is the prime cause of myoma and endometriosis then
medical treatment may be answer in near future. GENE THERAPY/
Does myomectomy procedure increase
fecundity? - No.
But does laparoscopic try of
endometriosis increase fecundity? - Yes.
But both forms of surgery (myomectomy
and chocolate cyst) – decreases preg compl and increase pregnancy outcome.
Medical TR (GnRH agonist/Aromatase
inhibitors either alone or concomitantly) therefore will take care both myoma
and associated endometriosis.
.
So far as pregnancy outcome is
concerned: Role of surgery in submucous myoma is
obvious but benefits in cases of Subserous and submucus myoma is doubtful.
Myomectomy should only be contemplated in cases with Subserous and submucus myoma if no other demonstrable cause for RSA.
For Recurrent abortion: Role of Myoma
with associated Endometriosis should be considered.
And modest benefit of myomectomy only-
counsel regarding risk/benefit profile.
In 10% of all RSA there will be
distortion of uterine cavities which mw be due to myoma, endometriosis, polyps,
IUA (Intra-uterine adhesions).
Submucus myoma are of type 0= absolutely
pdunculated, Type I= less than 50% is intramural and mostly hanging in cavity
and Type II= above 50% of volume of myoma is within the substance of uterus.
These cause (fibroids) cause distortion of endometrial cavity
Subserous= ≥ 50% is outside the
substance of uterus.
