Learning objectives• Menopause • Normal Postmenopausal Endometrium • Pathophysiology: before & after menopause • What warrants investigations • Case Studies• Endomtrial evaluation • Personal Experience• Review of Literature
•AFTER 12 MONTHS' SPONTANEOUS AMENORRHOEA.
•FSH >30
Menopause
Postmenopausal Endometrium
No more than thin line
2.3 mm ± 1.8 mm(0-10)
PRIOR TO MENOPAUSE:• Short cycle (↓ proliferative)
• ↑ Moderate Elevation of FSH
• Anovulation – Unapposed oest
- DUB
- Hyperplastic endo.
PATHOPHYSIOLOGY
PATHOPHYSIOLOGYOnce menopause occurs, oestrogen and progesterone are no longer produced by the ovaries; nor are they produced in any appreciable amounts by the liver and fat.
The endometrium regresses to some degree, and no further bleeding should occur.
If bleeding does resume - endometrium must be evaluated.

NO POST MENOPAUSAL BLEEDING
POST MENOPAUSAL BLEEDING
• PRECANCEROUS / CANCER of cervix & uterus• Benign conditions – eg. Polyp
• Chronic endometritis- eg. TB• Disorders of coagulation/ Blood dyscrasias
• Systemic Disease- eg. Hypertension • Drugs – anticoagulants, Tamoxiphen.
Herbal drugs, HRT
Postmenopausal Bleeding
• Benign conditions are most frequent causes of PMB but endometrial cancer is the most serious potential underlying cause
• One Should think endo. Ca untill proven otherwise.
75% of women with endometrial cancer
are postmenopausal.
RISK ASSESSMENT
RISK FACTORS FOR ENDOMETRIAL CANCER
are conditions typically associated with chronic elevations of endogenous estrogen levels or increased estrogen action at the level of the endometrium. These include
OBESITY. HISTORY OF CHRONIC ANOVULATION. DIABETES MELLITUS. ESTROGEN-SECRETING TUMORS. EXOGENOUS ESTROGEN UNOPPOSED BY PROGESTERONE . TAMOXIFEN USE. A FAMILY HISTORY OF LYNCH TYPE II SYNDROME
(HEREDITARY NONPOLYPOSIS COLORECTAL, OVARIAN, OR ENDOMETRIAL CANCER).
Systemic conditionsAbnormalities of the hematologic system
also must be considered as a possible cause of postmenopausal bleeding.
On rare occasions, AUB will be the first sign of leukemia or a blood dyscrasia.
Overuse of anticoagulant medications such as aspirin, heparin, and warfarin-which are taken with greater frequency by patients in this age group-may contribute to postmenopausal bleeding.
POSTMENOPAUSAL BLEEDING &
HRT • The occurrence of uterine bleeding or
spotting after the initiation of HRT is not unusual. More than half of HRT users will have some spotting or bleeding at the beginning of therapy.
• Usually such bleeding is lighter than a menstrual period and lessens with time; after 6 months, it stops completely in most women.
ENDOMETRIAL EVALUATION IS CALLED FOR WHEN :
1. any menopausal woman not taking HRT develops uterine bleeding after more than 1 year of amenorrhea.
2. any postmenopausal woman on HRT for 6 months or more with persistent uterine bleeding.
3. and any previously amenorrheic woman on HRT who begins bleeding without apparent cause.
CASE STUDY - 164 years old G2 P2 : 16 years postmenopausal
• Went to physician for pain in abdomen• Ultrasound revealed18 mm endometrial strip• No discharge/ No Bleeding, 70 kg, BMI - 32• Mild hypert, DM controlled.

CASE STUDY - 4• 54 year old G2 P2• Had HRT at age 50 for Hot flushes – 6 months• Presented with 3 episodes of vaginal bleeding over last 6 weeks (3 years after
menopause)• TVS show endometrial strip of 12 mm, Uterus- normal in size.
• E.B. proliferative endometrium• Hysteroscopy normal …. Spotting for 3 months
• Refused Hysterectomy

ENDOMETRITIS
ATT Given - EB &- Hysteroscopy
THE DURATION OR AMOUNT (STAINING VS GROSS) OF BLEEDING DOES NOT MAKE ANY DIFFERENCE.
IT GIVES NO CLUE TO DIAG.
SAME IS TRUE FOR ENDOMETRIAL THICKNESS.
RISK ASSESSMENT
• Vaginal ultrasonography.
• Saline infusion sonography (Hydrosonography)
• Office Endometrial biopsy.
• Conventional F/C or D/C
• Hysteroscopic guided biopsy.
DIAGNOSTIC TOOLS
Sensitivity and specificity are often used to summarise the performance of a diagnostic test.
Sensitivity is the probability of testing positive if the disease is truly present.
Specificity is the probability of testing negative if the disease is truly absent.
VAGINAL ULTRASOUND
Although the test is very specific , it isn't sensitive. Many women without endometrial cancer will have an endometrial thickness of 4 mm or more
VAGINAL ULTRASOUND
A CUT-OFF THRESHOLD OF 3 MM
OR 5MM ?cut-off point of 3 mm is less likely to
miss cancer than cut-offs of 5 mm.
But unfortunately a lower cut-off means a greater proportion of women requiring invasive investigation.
THE PATIENT RISK GROUP
•Low pre-test probability•On HRT•On tamoxifen therapy
• High pre-test Probability (high risk)
Cut off threshold 5mm Cut off threshold 3mm
Endometrial polyp in hyperechoic thickened endometrium
The introduction of intrauterine fluid (saline-infusion sonography) during transvaginal ultrasound is one of the most significant advances in ultrasonography of the past decade.
SALINE – INFUSION SONOGRAPHY
Uterine fibroids and adenomyomas generally are apparent on ultrasound. Uterine polyps may appear as a thickened endometrial stripe, but these and submucous myomas can be clearly identified as filling defects when a SIS is performed
SALINE – INFUSION SONOGRAPHY (SIS)
At transvaginal ultrasonography , the finding of a thickened central endometrial complex, with or without cystic changes, is often
nonspecific.
The Thickened endometrium may be a polyp
With polyps the endometrial-myometrialinterface is preserved
CYST
POLYP
well-defined, homogeneous,isoechoic to the endometrium
The Thickened endometrium
may be a polyp
With polyps the endometrial-myometrialinterface is preserved
POLYPcatheter
• Office Endometrial Biopsy
A useful suction endomtrial sampling (Probet) with 3.1 mm in outside diameter and no pump or syringe
required.
An endometrial suction sampling with syringe vacuum
SAMPLING OF THE ENDOMETRIUM
• OFFICE BIOPSY PROCEDURE (Probet Endometrial Curette, Vabra aspirator, Karman cannula) will agree with a D&C under GA ~95% of the time
• Office biopsy has a 16% false negative rate when the lesion is a polyp or the cancer covering less than 5% of the endometrium– Guido et al. J Reprod Med. 1995;40:553
Preoperative D&C will agree with diagnosis at hysterectomy - 95% of the time
The role today of the formal D&C or F/C probably is very limited because the diagnosis usually can be made in the office by endometrial biopsy (95%).
DILATATION AND CURETTAGE
“Gold STANDARD”
Hysteroscopic visualization has several advantages:
immediate office evaluation, visualization of the endometrium and
endocervix, the ability to detect minute focal
endometrial pathology and to perform directed endometrial biopsies.
