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 Heavy menstrual bleeding (HMB) Intermenstrual / Postcoital bleeding Dysmenorrhoea = ‘painful periods’ Premenstrual tension (PMT) Post-menopausal bleeding Oligo- or Amenorrhoea HMB - Etiology Endometrial origin Uterine / pelvic pathology Fibroids / Polyps Pelvic infection (Chlamydia) Endometrial or cervical malignancy Medical disorders Increased fibrinolysis and prostaglandins Coagulopathy / Thyroid disease / Endocrine disorders Iatrogenic (anti-coagulation / copper IUCDs) 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 Diagnosis Pelvic USS / Saline hysterosonography Hysteroscopy Management Operative removal with polyp forceps / curette or hysteroscopic resection Uterine Fibroids (Leiomyomata) Occur in 20 – 30% of women over 30 years Usually multiple Almost invariably benign Variable sizes, up to 20 cm or more Sex steroid-dependent – regress after the menopause Submucosal uterine fibroid Leiomyoma with central degeneration Leiomyoma Uterine fibroids Symptoms 50% asymptomatic HMB / Dysmenorrhoea Pressure effects Infertility Pregnancy complications Diagnosis Clinically enlarged uterus Pelvic USS Hysteroscopy / Laparoscopy Uterine fibroids - Management Conservative Medical Ensure Dx of fibroids and R/O adnexal mass Tranexamic acid / NSAIDs Mirena IUS GnRH agonists Surgical Myomectomy (hysteroscopic / laparascopic / by laparotomy) Hysterectomy Uterine artery embolization Postmenopausal bleeding Evaluation Postmenopausal bleeding (PMB) ALL WOMEN WITH PMB MUST BE INVESTIGATED Purpose of investigation: Exclude malignancy of endometrium and cervix Endometrial Ca in up to 4% of women with PMB Precursors of endometrial Ca (complex hyperplasia +/- atypia) PMB – Exclude malignancy History and assessment of risk factors Clinical Examination (!)

Would you carry out any investigations? What management options would you discuss and recommend?
