Menstrual disorders (26th April)

Mr James Campbell FRCOG
Background - Menstrual disorders




1 in 20 women aged 30-49 present to their
GP per year
£ 7 million (!) is spent per year on primary
care prescriptions
One of the most common reasons for
specialist referral
Accounting for a third of gynaecological
outpatient workload
Heavy menstrual bleeding (HMB)

Major impact on health-related quality of life


Major problem in public health




22% of otherwise healthy women
significant cost
invasive treatments
12% of all specialist referrals
Main presenting symptom for half of the
hysterectomies performed in the UK
Vessey M et al. The epidemiology of hysterectomy: findings of a large cohort study.
Br J Obstet Gynaecol 1992; 99; 402-407.
Increasing prevalence

More periods per lifetime





Earlier menarche
Increased life expectancy
Ability to regulate fertility
Less time spent breastfeeding
More demanding lifestyles and reduced
tolerance of troublesome periods
Menstruation
Shedding of the superficial layers
of the endometrium
following the withdrawal
of ovarian steroids
Normal menstruation





Menarche
Menopause
Regular cycles
Menstrual loss
Pelvic discomfort
- 13 years
- 51 years
– 5 / 28
– 40ml (<80ml)
Menstrual disorders

Clinical evaluation
& management
Patient presenting
with
heavy menstrual bleeding
TAKE A HISTORY
Relevant history







Frequency and intensity of bleeding –
Menstrual diary
Pelvic pain / Pressure symptoms
Abnormal vaginal discharge
Sexual and contraceptive history
Obstetric history
Smear history
History of coagulation disorder
Examination

Clinical examination



General appearance (? Pallor)
Abdominal examination (?Pelvic mass)
Speculum examination
 Assess

vulva, vagina and cervix
Bimanual examination
 Elicit
tenderness
 Elicit uterine / adnexal enlargement
Investigations

Indicated if age > 40 years
or failed medical treatment







FBC / Coagulation screen
Thyroid function (only if clinically indicated)
Smear / Endocervical swabs / High vaginal swabs
Pelvic ultrasound (USS)
Saline hysterosonography (?Polyps)
Hysteroscopy
Endometrial biopsy (Pipelle / D&C)
Hysteroscopy
Endometrial biopsy
Endometrial Hyperplasia
WHO Classification

Simple hyperplasia
No risk of malignant transformation

Complex hyperplasia
Low risk (~5%)

Simple atypical hyperplasia
Unknown risk

Complex atypical hyperplasia
Significant risk (at least 30%)
Endometrium: simple hyperplasia
Complex non-atypical hyperplasia
Complex atypical hyperplasia
Causes of HMB
Endometrial origin
“Dysfunctional uterine bleeding”
Anovulatory Cycles
Reasons for heavy menstrual bleeding

Endometrium develops


Corpus luteum fails to develop




under the influence of oestrogen
absence of progesterone
Spiral arteries do not develop properly and are
unable to undergo vasoconstriction at the time
of shedding
Endometrium supplied by thin-walled vessels
Result – prolonged heavy bleeding
Persistent Anovulation



Infertility
Endometrial hyperplasia
Increased risk of endometrial carcinoma
Management of HMB

Anti-fibrinolytics


Prostaglandin synthetase inhibitor






Tranexamic acid (Cyclokapron®)
Mefenamic acid (Ponstan®)
Combined oral contraceptive pill (COC)
Progestogens
GnRH analogues
Endometrial ablation
Hysterectomy
Management - Progestogens



Luteal phase progestogens
(only useful if anovulatory)
Long-acting progestogens
(Depoprovera / Implanon)
Mirena IUS
Mirena IUS
Endometrial ablation


Day-case procedure or out-patient setting
1st generation


2nd generation




Trans-cervical resection
Thermal balloon
Microwave
Impedance controlled
Similar outcome to Mirena IUS
Hysterectomy

“Treatment of choice for cancer,
but a choice of treatment for menorrhagia”
Lilford RJ (1997) BMJ 314; 160 - 161



Surgical access
Total versus subtotal hysterectomy
Removal versus conservation of ovaries
and use of HRT
Abdominal hysterectomy
Vaginal hysterectomy
Uterine pathology
Evaluation & Management
Polyps and Fibroids
Endometrial polyps







Localised overgrowths of endometrium projecting into
uterine cavity
Common in peri- and postmenopausal women
(10 – 24% of women undergoing hysterectomy)
Account for 25% of abnormal bleeding in both pre- and
postmenopausal women
Typically benign, but malignant change can rarely occur
Non-neoplastic lesions of endometrium containing
glands, stroma and thick-walled vessels
Glands may be inactive, functional or hyperplastic
Association with tamoxifen use
Endometrial Polyp
Endometrial polyps
