2. Introduction
Endometriosis initially described by Von
Rokitansky in 1860.
Endometriosis is a clinical and pathological
entity.
It is characterized by the presence of tissue
resembling functional endometrial glands and
stroma outside the uterine cavity.
3-Sep-15 2Dr Shashwat Jani 9909944160
4. It is not a neoplastic condition, but
malignant transformation is possible.
3-Sep-15 Dr Shashwat Jani 9909944160 4
5. Incidence
3 – 10 % of women of reproductive
age
20-40% in infertile women
5-20% with chronic pelvic pain
20-50% asymptomatic, found during
laparoscopy and sterilization.
50% dysmenorrhea
3-Sep-15 5Dr Shashwat Jani 9909944160
6. Etiology
Estrogen dependent disease
Sampson’s theory
Ectopic transplantation of endometrial tissue.
Meyer’s theory
Coelomic metaplasia.
Halban's theory:
Induction theory
Genetic factors
Immunologic factors
Unknown factor
Autoimmune
Combination of the Above
Environmental factors - dioxin
No Single Theory Explains All Cases of
Endometriosis
3-Sep-15 6Dr Shashwat Jani 9909944160
7. Risk Factors
Family history of endometriosis.
Early age of menarche
Short menstrual cycles (<27 d)
Long duration of menstrual flow (>7 d)
Heavy bleeding during menses
Inverse relationship to parity
Delayed childbearing
Defects in the uterus or fallopian tubes
less use of OCs
3-Sep-15 7Dr Shashwat Jani 9909944160
11. Dysmenorrhea
Most common symptom
Pain starts a few days prior to menstruation,
gets worse during menstruation( secondary
dysmenorrhoea)
Pain due to Increased secretion of PGF2α,
Thromboxane β2 from endometriotic tissue.
3-Sep-15 11Dr Shashwat Jani 9909944160
12. Abnormal Menstruation
- Menorrhagia is a predominant abnormality.
- Polymennorhoea, premenstrual spotting also
occur.
Dyspareunia
It is usually deep, due to stretching of the structures of the
Pouch of Douglas or direct contact tenderness found in
endometriosis of rectovaginal septum or Pouch of
Douglas and with fixed retroverted uterus.
3-Sep-15 12Dr Shashwat Jani 9909944160
13. Lower Abdominal Pain
Abdominal pain
lower abdominal pain or backache
May be due to inflammation in
peritoneal implants due to cystic bleeding
Irritation or invasion of nerve
Action of inflammatory cytokines
released by the macrophages.
3-Sep-15 13Dr Shashwat Jani 9909944160
14. Infertility
• Mechanical interference---
• Pelvic adhesions
• Chronic salpingitis
• Impaired oocyte pickup
• Altered tubal motility
• Distortion of tubo-ovarian relations
• Alteration in peritoneal fluid
• Increased concentration of prostaglandins
• Increased number of macrophages
• Increased production of cytokines
• Phagocytosis of sperms
3-Sep-15 14Dr Shashwat Jani 9909944160
16. Clinical Examination
General conditions-
Pallor + due to Menorrhagia
P/A - Mass may be felt in lower abdomen arising from
the pelvis
Enlarged chocolate cyst or tuboovarian mass,
due to endometriotic adhesions.
The mass is tender with restricted mobility.
L/E- See Vulva and other structures
P/S- See cervix, vagina for any deposits, discharge or
growth.
3-Sep-15 16Dr Shashwat Jani 9909944160
17. Bimanual Pelvic Examination
o Tender uterosacral ligament
o Cul-de-sac nodularity found
o Induration of the rectovaginal septum
o Fixed retroversion of the uterus
o Adnexal masses and generalized or localized
pelvic tenderness present
o Uterosacral nodules may be found
3-Sep-15 17Dr Shashwat Jani 9909944160
20. ASRM staging has poor correlation with
pregnancy rate.
In 2009 new staging system was proposed
called “ Endometriosis Fertility Index. “
EFI is numerical measure of functional
anatomy based on assessment of tubes,
fimbriae and ovaries.
EFI score 0 to 10
(0 – poorest and 10 – the best prognosis).
3-Sep-15 20Dr Shashwat Jani 9909944160
22. USG
First line tool for suspected endometriosis
Detects ovarian cysts ( Endometrioma ) and rule
out other causes
May have role in detection of involvement of
Bladder & Rectum.
Detection of Endometrioma using USG is excellent
with 83 % Sensitivity and 98 % Specificity.
3-Sep-15 22Dr Shashwat Jani 9909944160
23. Classical Appearance :
Homogenous , Hypoechoic mass with in the
ovary with diffuse low level internal echoes
with hyperechoic foci within the wall.
Wall nodularity should be differentiated
from hyperechoic foci within the wall.
95% of endometriomas display low level of
internal echoes.
D/D : Dermoid , Hemorrhagic , Cystic
neoplasm
3-Sep-15 Dr Shashwat Jani 9909944160 23
24. TRS :
- To look at Sigmoid for endometriotic infiltrates.
- Rounded or triangular hypoechoic deposits.
- Infiltration of bowel wall is seen as thickening
of Muscularis Propria.
Doppler :
• Better studied in late follicular & early luteal
phase.
• Blood flow in Endometrioma is usually
Pericystic with RI > 0.45.
3-Sep-15 Dr Shashwat Jani 9909944160 24
25. CT Scan / MRI
MRI may detect even smallest of lesions
and distinguish hemorrhagic signal of
endometriotic implants; superior to CT scan in
detecting limits between muscles and abdominal
subcutaneous tissues
MRI demonstrated to accurately detect
rectovaginal disease and obliteration in more
than 90% of cases when ultrasonographic gel was
inserted in the vagina and rectum
3-Sep-15 25Dr Shashwat Jani 9909944160
26. Sensitivity 90 %
Specificity 98 %
Major role is to help visualize
laparoscopic blind spots such
as retroperitoneal space and
lesions obscured by dense
adhesions or typical lesions.
DPE is best diagnosed
and located by TRS &
MRI.
3-Sep-15 Dr Shashwat Jani 9909944160 26
27. I.V. Urography :
- Serosal deposits are seen at dome of bladder.
- Involvement of Ureter is also seen.
Barium Enema :
Serosal deposits are causing thickening
and fibrosis of Muscularis propria which is
demonstrated as asymmetric narrowing or
eccentric intramural filling defect.
3-Sep-15 Dr Shashwat Jani 9909944160 27
28. Histological Diagnosis
• Positive confirms But Negative doesn’t
exclude.
• Visual is usually adequate but histology of any
one lesion is ideal
• In > 4 cm endometrioma & Deep infiltrating
disease – histology should be done to identify
endometriosis and exclude malignancy.
3-Sep-15 Dr Shashwat Jani 9909944160 28
29. • Microscopically :
Implants consist of endometrial glands and
stroma with or without hemosiderin laden
macrophages.
3-Sep-15 Dr Shashwat Jani 9909944160 29
30. Biochemical Marker
CA - 125
Cancer Antigen-125, a high molecular weight glycoprotein
expressed on the cell surface of some derivatives of
embryonic coelomic epithelium.
It is elevated towards the end of the luteal phase and during
menstruation.
In many other conditions elevated CA-125 concentration
like PID, adenomyosis, uterine leiomyoma, menstruation,
pregnancy, epithelial ovarian cancer, pancreatitis, chronic
liver disease.
3-Sep-15 30Dr Shashwat Jani 9909944160
31. The result of most studies suggest that CA-
125 is not sufficiently sensitive to identify
lesser stages of endometriosis.
CA-125 is NOT reliable as a
screening test.
3-Sep-15 31Dr Shashwat Jani 9909944160
32. Surgical Diagnosis
“ Diagnostic Laparoscopy is
the Gold Standard
investigation for
Endometriosis…”
3-Sep-15 32Dr Shashwat Jani 9909944160
33. For a definitive diagnosis of endometriosis,
visual inspection of the pelvis at laparoscopy is
the gold standard investigation, unless disease
is visible in the posterior vaginal fornix or
elsewhere…
3-Sep-15 Dr Shashwat Jani 9909944160 33
34. Can classify the extent and severity of disease.
A double puncture technique is essential.
The grasper placed through the lower abdomen
sheath permits mobilization of the tube and
ovaries.
3-Sep-15 34Dr Shashwat Jani 9909944160
35. Inspect the lateral side wall, all ovarian
surface, both sides of the broad ligament,
the bladder, bowel serosa, inferior aspect
of cul-de-sac, evaluation of the
uterosacral ligaments and rectal serosa.
To avoid under diagnosis it should not
be performed during or within 3 months
of hormonal therapy.
3-Sep-15 Dr Shashwat Jani 9909944160 35
36. Findings are…
Typical “powder-burn or “gunshot” lesions on the
serosal surface of the peritoneum. These lesions
are black, blue or dark brown, nodules or small
cysts containing old hemorrhage surrounded by
variable degree of fibrosis.
White lesions are predominantly fibromuscular
scarring with scattered glandular and stromal
elements.
Brown lesions are mainly haemosiderin deposits.
Peritoneal defect and subovarian adhesions
contain endometriosis in 40% -70%.
3-Sep-15 36Dr Shashwat Jani 9909944160
38. For ovarian endometriosis- Large ovarian
endometriotic cysts are usually located
on the anterior surface of the ovary and
associated with retraction, pigmentation
and adhesions to the posterior
peritoneum.
Ovarian endometriotic cyst contain a
thick, viscous dark brown fluid.
(Chocolate fluid)
3-Sep-15 38Dr Shashwat Jani 9909944160
39. 3-Sep-15 39Dr Shashwat Jani 9909944160
Chocolate cyst– sometimes it is confused with
hemorrhagic corpus luteum cysts and neoplastic cysts.
Biopsy must be done.
