2 is the permanent cessation of menstruation resulting from loss of ovarian follicular activity. It can only be determined after 12 months' spontaneous amenorrhoea. Mean age is 51 years.

3 is the period of time in which the ovaries are beginning to fail, where endocrine, biological, and clinical changes are seen. It ends with the final menstrual period. Length of the transition is approximately 4 years

4 is the time period over which the ovaries are failing (when symptoms begin) up until the cessation of menstruation, and ends 12 months after the final menstrual period.

5 is the time after the menopause, that is, after the permanent cessation of menstruation. It can only be determined after 12 months of spontaneous amenorrhoea. In practice this definition is difficult to apply, especially in women who have started hormone replacement therapy (HRT) in the perimenopause. It has been estimated that by the age of 54 years, 80% of women are postmenopausal [McKinlay et al, 1992; DTB, 1996].

6 occurs after bilateral oophorectomy with or without hysterectomy. Premature menopause may also be radiation- or chemotherapy-induced, or occur after hysterectomy with ovarian conservation.

7 A premature menopause is one that occurs before the age of 40 years. Primary premature menopause may occur at any age and present as amenorrhoea. Not all women have acute symptoms. FSH levels are elevated. Spontaneous fertility may recur.

8  It is possible to discontinue the HRT or COC pill and measure the follicle-stimulating hormone (FSH) level after 6-8 weeks. The POP does not affect FSH levels and so does not need to be stopped for FSH testing [Gebbie, 1998].  An FSH value over 30 IU/L is in the postmenopausal range, but should be repeated 4-8 weeks later to confirm this.  Even if the FSH levels are in the postmenopausal range, this may not reliably indicate infertility, and contraception should be continued for a further 1 year if the woman is over 50 years old, or a further 2 years if she is under 50 years old.

9 Benign conditions is most frequent causes of PMB but endometrial cancer is the most serious potential underlying cause

10 75% of women with endometrial cancer are postmenopausal.

11 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).

12 Investigate all bleeding during menopause unless the patient is on cyclic replacement therapy with normally anticipated withdrawal bleeding. The duration or amount (staining vs gross) of bleeding does not make any difference.

13 Tamoxifen use Tamoxifen therapy is associated with a two- to threefold increased risk of endometrial cancer in postmenopausal women. TVUS of patients on this therapy typically shows an increased endometrial thickness. Risk appears to increase with higher cumulative doses of tamoxifen and longer duration of treatment.

14 Postmenopausal bleeding and 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.

15 Sequential (or cyclical) combined regimens cause scheduled bleeding in most users. Continuous combined regimens are associated with a reduced relative risk of endometrial cancer but may cause unpredictable spotting or bleeding during initial use. Postmenopausal bleeding and HRT

16 Systemic conditions Abnormalities 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.

17 Once menopause occurs, estrogen 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. When bleeding does resume, therefore, endometrium must be evaluated.


19 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.

20 As TVUS is a non invasive test with 91 % sensitivity and 96 % specificity. it should be done for all women with postmenopausal bleeding. if the endometrial thickness is >5mm. and if the patient pre test probability is low,office endometrial biopsy and SIS should be done to determine whether the endometrium is symmetrically thickened. BUT if the patient pre test probability is high, a fractional curettage biopsy or a hysteroscopic guided biopsy is recommended.

21 TVUS endometrial thickness is > 5mm endometrial thickness is < 5mm If low risk If high risk D/C biopsy OR hysteroscopy office endometrial biopsy and SIS But symptoms persist follow In women with continued bleeding after a negative initial evaluation, further testing with hysteroscopically directed biopsy is essential,


23  Vaginal ultrasonography.  Hydrosonography.  Endometrial biopsy.  Office biopsy.  D/C biopsy.  Hysteroscopic guided biopsy.

24 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.


26 Transvaginal ultrasound has a good correlation with pathologic endometrial findings. Using an endometrial thickness from myometrium to myometrium of 5 mm (considered the upper limit of normal) sensitivity is 91 percent and specificity is 96 percent. Although the test is very specific, it isn't sensitive. Many women without endometrial cancer will have an endometrial thickness of 5 mm or more

27 Identification and measurement of the endometrial echo and descriptions of the echogenicity and heterogeneity of the endometrium are key to defining endometrial health

28 A ‘negative’ TVUS result for a local cut-off point of 3 mm is therefore less likely to miss cancer (i.e. have a greater sensitivity) than cut-offs of 5 mm. But unfortunately a lower cut-off points also result in a greater proportion of ‘false positives’ requiring further investigation. A cut-off threshold of 3 mm or 5mm ?

29 Adopting more than one cut off value may allow the interpretation of the test to be tailored to the patient’s pre-test probability (i.e. the patient risk group). A cut-off threshold of 3 mm or 5mm ?

30 Low pre-test probability On HRT On tamoxifen therapy High pre-test Probability (high risk) Cut off threshold 5mmCut off threshold 3mm the patient risk group

31 If both pre-and post test probability are reassuring, no further action need be taken. Further investigations should be carried out if symptoms recur.

32 If both pre-and post test probabilities are not satisfactory with this level of reassurance, further investigation is justified. This should include an endometrial biopsy to obtain a histological assessment.

33 For women on sequential combined HRT presenting with unscheduled bleeding, or those who are tamoxifen users, TVUS using a cut-off point of 5 mm or less should be used to exclude endometrial cancer.


35 One of the difficulties with using the endometrial stripe as a criterion for further diagnostic tests (eg, endometrial biopsy) is that several conditions may be present that give a false reading on the endometrial stripe. This is particularly true in a patient who might have an endometrial polyp or who has been taking tamoxifen.


37 The introduction of intrauterine fluid (saline-infusion sonography) during transvaginal ultrasound is one of the most significant advances in ultrasonography of the past decade.

38 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 sonohysterography is performed

39 to direct the patient to a visually guided hysteroscopic procedure rather than a potentially unsuccessful blind biopsy procedure. At transvaginal US, when the endometrium cannot be accurately measured or when there is a nonspecific thickened central endometrial complex, sonohysterography can provide additional information and can be used to direct the patient to a visually guided hysteroscopic procedure rather than a potentially unsuccessful blind biopsy procedure.

40 At transvaginal ultrasonography, the finding of a thickened central endometrial complex, with or without cystic changes, is often nonspecific.

41 CYST POLYP well-defined, homogeneous, isoechoic to the endometrium With polyps the endometrial-myometrial interface is preserved The Thickened endometrium may be a polyp

42 catheter The Thickened endometrium may be a polyp POLYP With polyps the endometrial-myometrial interface is preserved

43 broad-based, hypoechoic, With myomas the endometrial- myometrial interface is distorted The Thickened endometrium may be a Submucosal leiomyomas

44 A B Endometrium thickness = A-B diffuse thickening of the echogenic endometrial stripe without focal abnormality The Thickened endometrium may be an endometrial hyperplasia

45 Endometrial cancer is typically a diffuse process, but early cases can appear as a polypoid mass Endometrial cancer


47 The role today of the formal D&C probably is very limited because the diagnosis usually can be made in the office. Dilatation and curettage

48 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. Hysteroscopic-directed biopsy
