Endometriosis is the presence of endometrial tissue outside the uterus that induces a chronic inflammatory reaction. There are several proposed theories for its pathogenesis, including retrograde menstruation, coelomic metaplasia, and metastasis. Symptoms include pelvic pain and infertility. Diagnosis is typically made by laparoscopy to visualize lesions. Treatment involves pain management, preservation of fertility, and involves medical therapy with hormones or NSAIDs and surgery. The goal of management is individualized based on the patient's symptoms, disease severity, and fertility desires.

endometrial implants outside its normal
place i.e uterine cavity
Incidence:20-25% in reproductive age
group

3. Implantation theory :
Sampson's pioneering work in 1922 attributed endometriosis
to reflux of menstrual endometrium through the fallopian tubes. Occurrence of
scar endometriosis following classical caesarean section, hysterotomy, myomectomy
and episiotomy further supports this view.
Coelomic metaplasia theory :
Meyer and Ivanoff (1919) propounded that endometriosis arises as a result of
metaplastic changes in embryonic cell rests of embryonic mesothelium.
Hormonal stimulation of Embryologically similar tissues to the Mullerian
ducts.
Metastatic theory :
Suggested by Halban et al. (1924) that embolization of menstrual fragments
through vascular or lymphatic channels, explain its occurrence at less accessible
sites like the umbilicus, pelvic lymph nodes, ureter, rectovaginal septum, bowel
wall, and remote sites like the lung, pleura, endocardium and the extremities.

4. Hormonal influence :
The initial genesis of endometriosis, its further development depends on the
presence of hormones, mainly oestrogen. Pregnancy causes atrophy of
endometriosis through high progesterone level. Regression also follows
oophorectomy and irradiation. Endometriosis is rarely seen before puberty and
it regresses after menopause. Hormones with antioestrogenic activity also
suppress endometriosis and are used therapeutically.
Immunological factor :
The peritoneal fluid in endometriosis shows the presence of macrophages and
natural killer (NK) cells. Impaired T cell and NK cell activity and altered
immunology.
Other factors :
Genetic - familial tendency reported in 15% cases, multifactorial, vaginal or
cervical atresia which encourage retrograde spill.
Prostaglandins.

5. Uterine :
Adenomyosis (50%)
Extra uterine :
- Ovary 30%
-Pelvic peritoneum

9. Early lesions appear papular and red vesicles are filled with
haemorrhagic fluid with surrounding flame-like lesions.
Over time, these vesicles change colour and endometriotic areas
appear as dark red, bluish or black cystic areas adherent to the site.
Scarring in the endometriosis makes it puckered. Atypical lesions
such as non-pigmented areas or yellowish-white thick plaques have
been noticed, which are healed lesions. Powder burnt areas are the
inactive and old lesions seen scattered over the pelvic peritoneum.
Chocolate cysts of the ovaries represent the most important
manifestation of endometriosis. To the naked eye, the chocolate cyst
shows obvious thickening of tunica albuginea, and vascular red
adhesions are well marked on the undersurface of the ovary. The
inner surface of the cyst wall is vascular and contains areas of dark
brown tissue. The chocolate cyst lies in the ovary and adherent to
lateral pelvic wall.

13. On History
Common symptoms :
Chronic pelvic pain, worsening dysmenorrhea,
acquired dyspareunia, infertility, premenstrual
spotting, dyschezia.
Risk factors :
First degree relative affected, short menstrual cycles,
long duration of menstrual flow, low parity,
infertility, fair complexioned, reproductive tract
obstructive anomalies. However tubectomised

14. Examination
On bimanual pelvic examination, fixed retroverted uterus,
bilateral pelvic tenderness, fixed or enlarged ovaries and painful
uterosacral nodularity.
Deeply infiltrating nodules are most reliably detected when
clinical examination is performed during menstruation.
Adenomyotic uterus is seldom > 12 weeks, soft, smooth & tender
in contrast to fibroid uterus. Isolated adenomyoma can be
differentiated by presence of localised tenderness

15. Investigations
Laparoscopy: Gold standard It should not be
performed within 3 months of hormonal
treatment to prevent under diagnosis
Ultrasound: Ultrasound has a limited role,
however the addition of colour doppler claims
to increase the sensitivity to 91.8%, specificity
of 91.3%
MRI –useful
Ca 125-Maybe elevated in severe

17. Histological Confirmation:
Visual inspection is usually adequate but histological
confirmation of at least one lesion is ideal.
In cases of ovarian endometrioma >3 cm in diameter
and in deeply infiltrating disease, histology is a must to
rule out malignancy.

18. Laparoscopy:
(Sensitivity: 97%, Specificity 95%) Types of lesions
on laparoscopy: Powder burn or black lesions
White opacified peritoneum Glandular
excrescences Flame like red lesions
Peritoneal pockets or windows Clear vesicles Yellow brown
patches
Unexplained adherence of ovary to peritoneum of
ovarian fossa
Encysted collection of thick chocolate coloured or
tarry fluids
Adhesions to posterior lip of broad ligaments/other pelvic
structures

24. Sonographic Features :
Endometritic cysts (oval or round)- capsulated, fine homogeneous,
uniform, granular echoes, anechoic, single or multiple, unilateral
or bilateral
On Doppler: no vascularity within the mass Ovarian
adhesions to uterus
Free floating fimbria on sonosalpingography

25. Several Proposed Schemes
Revised AFS System: Most Often Used
Ranges from Stage I (Minimal) to Stage IV (Severe)
Staging Involves Location and Depth of Disease,
Extent of Adhesions

29. Recognize Goals:
– Pain Management
– Preservation / Restoration of Fertility
Discuss with Patient:
– Disease may be
Curable
Chronic and Not
– Optimal Treatment Unproven or
Nonexistent

30. Management of Endometriosis must be ‘tailor
made’ taking into account, patients profile,
presenting symptoms, impact of the disease and
effects of treatment on day to day life.

31. Empirical treatment of pain symptoms without
definitive diagnosis of endometriosis, a
therapeutic trial of hormonal drug to reduce
menstrual flow is appropriate.
Medical Therapy for endometriosis can be used
either as primary therapy or in conjunction with
surgery preoperatively or postoperatively-
Sandwich Therapy

32. How effective are NSAIDS in treating endometriosis associated pain?
There is inconclusive evidence to show whether NSAIDS are effective
in managing pain caused by endometriosis
Advantages:
Not operator dependent Less
expensive
No surgical/anesthetic risk
No post- op adhesion formation
Disadvantages:
Prolonged treatment Gastric
ulceration Temporary relief

33. • GnRH analogues: creates a pseudo menopausal
state
• Advantages:
• Reduction in pelvic vascularity and inflammation
• Reduction in size and activity of endometriotic
implants
• Reduction in ovarian cyst diameter
• Reduction in cyst wall diameter
• Disadvantages:
• Hypoestrogenic state
• Bone loss(can be controlled by add back regimen-

34. Danazol: pseudo-menopausal state Inhibits ovarian steroid-
genesis, decreases pulsatile GnRH release, decreases
gonadotrophins-antioestrogenic, antiprogestogenic,
androgenic effects
Dosage: 400mg/day
Efficacy: crude pregnancy rate 28-47%

35. Progesterone:- Pseudo pregnancy (Kristner’s Regime) state. Acts by
decidualisation and atrophy of the estrogen dependent
endometriotic foci
Common progesterone:- Medroxy progesterone acetate,
norethesiterone, dydrogesterone,
DMPA:- cost effective, readily available, 66%complete resolution
LNG- IUS(Mirena):- Reduces endometriosis associated pain(symptom
control over 3 years)
Side effects:- Irregular Bleeding, weight gain, fluid retention, breast
tenderness, mood changes.

36. Gestrinone: Androgenic, progestogenic and antiestrogenic
Dosage: 1 - 2 5 - 2 - 5 m g biweekly
Side effects : similar to danazol

37. Combined OC Pills:
 To reduce the frequent prolonged bleeding not
recommended in infertile endometriotic women.
 However COCs are the only effective prophylaxis
in against endometriosis.

38. RU 486: antiprogestogenic activity with minimal or no
other endocrinologic effects
Aromatase Inhibitor: Acts on the diseased endometriotic
implants to decrease local oestrogen production-to
inhibit the growth of implants.
Interferons: combination with GnRH have resulted in
higher cumulative pregnancy rates and monthly
fecundity rates
SERMs: Selective antiestrogenic activity on the
endometrium, agonist activity on bones and

41. Indications:
Mild Endometriosis is associated infertility.
Endometrioma >4 cm in diameter Endometriosis of
rectovaginal septum or rectal wall Failed Medical therapy
Intolerable side effects of medical therapy Endometriosis
with other surgically correctable infertility factors

42. Pre operative assessment: MRI or Ultrasound with
or without IVP, Barium enema, sigmoidoscopy
Preoperative and post-op medical management:
GnRh-a like goserilin for 3 months preoperatively
reduces the size and AFS score.
Postoperative therapy gives longer period of
remission.

43. Primary operation is the best opportunity
Best outcome by excision of the lesion
Complete excision has lowest recurrence of
19%
Adhesions require excision rather than
simple division

44. Electrosurgical instruments are used for excision of
endometriotic focii pelvic peritoneum, however
the depth of dissection is unpredictable & hence
damage to gut.
Sophisticated energy sources available are:
1. Carbon dioxide or Nd YAG laser: Allows
vaporisation; excision; high cost
2. Harmonic scalpel: Ultrasound mechanical source,
for cutting and coagulation
3. Argon beam: for widespread superficial lesion
4. Helica thermal coagulator: effective in
vaporisation with risk of thermal damage.

45. Surgery when pain relief is the priority:
Early stage disease: LUNA along with ablation of
endometrial deposits improves outcome
Moderate to severe disease: Removal of the entire
lesion recommended
Endometrioma:
1. For large unilateral endometrioma-
salpingoopherectomy of the affected side;
2. Bilateral large endometrioma: < 40years: ovarian
tissue to be conserved as far as possible
3. Insufficient evidence to justify use of pre op or
post op hormones
4. HRT recommendation after bilateral
salpingooherectomy is controversial

46. Surgery when infertility is the priority
Early stage disease: Laparoscopic excision or
ablation with adhesiolysis
Moderate to severe endometriosis: role of surgery
is uncertain(overactive excision may reduce
fertility)
Endometrioma: laparosopic cystectomy better
than drainage and coagulation.
Post op hormonal treatment has no beneficial effect
on pregnancy rates after surgery
Tubal flushing improves pregnancy rates.

48. Treatment with IUI improves fertility in minimal to
mild endometriosis
IVF appropriate especially when tubal function is
compromised, if there is male factor infertility
and/or other treatments have failed.
Treatment with GnRH agonists for 3-6months
before IVF increases the rate of clinical
pregnancies
Laparoscopic ovarian cystectomy is recommended
for endometriomas >4cm in diameter.
