• Honorary Clinical Associate Professor

2
Outline

• General approach to gynaecological problems
• Management and recent advances
• vaginal discharge
• abnormal vaginal bleeding
• dysmenorrhoea
• uterine fibroid
• Useful resources

3
History and physical examination

• Menstrual history LMP
• Contraception
• Cervical smear history
• Can the patient be pregnant
• Obstetric history
• Patients concerns
• Is pelvic examination necessary

4
Investigations

• Pregnancy test
• Swabs for culture
• Cervical smear
• Endometrial aspiration
• Ultrasound pelvis

5
Need referral

• Reasons for referral
• 1. Unsure diagnosis
• 2. Special diagnostic tests
• 3. Treatment
• 4. Second opinion
• Many common gynaecological problems can be
  managed by GP

6
Should investigations be done before referral

• 1. Affect decision to refer
• 2. Delay the referral
• 3. Reliable laboratory

7
Referral letter

• Name and age of the patient
• Reason for referral
• Any investigations and treatment before the
  referral
• Wish to continue post-referral care
• Ix reports copies of X-ray ultrasound images
  are very helpful

8
Reply from hospital specialist follow up

• 1. Confirm with patient diagnosis treatment and
  plan of management
• 2. Clarify with specialist if needed
• 3. Your feedback is welcomed

9
Vaginal Discharge

• Physiological
• midcycle premenstrual
• Pathological
• odour itchiness
• blood stained
• Postmenopausal atrophic vaginitis
• May need to explore hidden anxiety especially
  anxiety about STD

10
Vaginal Discharge

• Speculum examination is necessary and digital
  examination preferred
• Need to take culture swab
• Typical moniliasis treat without culture take
  swab if treatment fails
• Need to screen for STD

11
Vaginal Discharge

• Need to refer
• Recurrent
• Blood stained and not midcycle
• Fail to response to treatment
• Uterine or cervical pathology suspected
• Postmenopausal and fails to respond to HRT

12
Vaginal Discharge

• In children
• Think of foreign body and
• Sexual abuse
• May need referral

13
Abnormal vaginal bleeding

• Postmenopausal bleeding (PMB)
• Reproductive age group
• irregular
• inter- pre- or post-menstrual spotting
• heavy bleeding (menorrhagia)

14
Abnormal vaginal bleeding

• Malignancies
• Carcinoma of corpus
• Carcinoma of cervix
• Oestrogen producing ovarian tumour
• Premaligant conditions
• Atypical endometrial hyperplasia
• CIN (usually do not present with bleeding)

15
Abnormal vaginal bleeding

• Benign conditions
• Polyps endometrial cervical
• Fibroid
• IUCD
• Drug effect
• Systemic diseases
• DYSFUNCTIONAL UTERINE BLEEDING IS THE MOST COMMOM

16
Abnormal vaginal bleeding

• Assessment of the endometrium (not needed for
  women with very low risk of Ca endometrium)
• endometrial aspirate
• ultrasound pelvis (transvaginal) to assess
  endometrial thickness
• hysteroscopy

17
Abnormal vaginal bleeding

• When to refer
• over the age of 40
• high risk of endometrial Ca (obesity DM PCOD)
• uterus gt 10 week size or irregular
• cervical pathology suspected
• no response to medical treatment

18
Abnormal vaginal bleedinga practical approach
(1)

• History
• age
• pattern of bleeding
• risk factors for endometrial Ca
• pregnant
• drug
• previous treatment
• last cervical smear

19
Abnormal vaginal bleedinga practical approach
(2)

• Physical examination
• general obesity thyroid pallor pulse
• abdomen palpable mass
• pelvis cervical or vaginal lesion uterine size

20
Abnormal vaginal bleedinga practical approach
(3)

• Over 40
• or high risk of endometrial Ca
• or genital tract lesion suspected (except
  cervical polyp) including uterus big
• or previous medical treatment fail
• REFER (or endometrial aspiration and TV USG)

21
Abnormal vaginal bleedinga practical approach
(4)

• None of the above factors
• consider investigations
• cervical smear if sexually active and last smear
  more than 1 year ago
• CBP if menorrhagia
• ultrasound pelvis if PV not possible
• thyroid function coagulation only when history
  suggestive

22
Abnormal vaginal bleedinga practical approach
(5)

• Medical treatment (for women under 40 with no
  suspicion of organic lesions)
• Hormonal (for irregular bleeding as well as
  menorrhagia)
• combined OC
• progestogen only (21 days needed)
• Non-hormonal (for menorrhagia)
• NSAID
• antifibrinolytic agent

23
Abnormal vaginal bleedinga practical approach
(6)

• Choice of medical treatment for irregular vaginal
  bleeding
• combined OC gives much better cycle control
  (start with a preparation containing 50ug EE)
• progestogen only (when oestrogen contraindicated)

24
Abnormal vaginal bleedinga practical approach
(7)

• Choice of medical treatment for menorrhagia
• NSAID 30 decrease in blood loss relieve
  dysmenorrhoea as well
• Antifibrinolytic (transamine) 50 decrease
• Combined OC effective but need to take through
  out the month effective contraception as well
• Progestogen only less effective need 21 days
  not effective contraception
• Haematinics if anaemic
• combinations can be used

25
Abnormal vaginal bleedinga practical approach
(8)

• When to consider medical treatment as failure
• Failure to relieve patients symptoms after 3
  months
• Remains anaemic after 3 months

26
Abnormal vaginal bleedingother modalities of
treatment

• Levonorgesterol releasing IUCD (Mirena)
• Endometrial ablation
• pregnancy contraindicated after ablation
• Hysterectomy

27
Abnormal vaginal bleedingPost-referral management

• Pathology excluded
• Treatment plan suggested e.g
• non-hormonal therapy
• hormonal therapy usually for 6 months
• just follow the treatment plan
• refer back if treatment failure
• Follow up after special treatment

28
Dysmenorrhoea

• Primary
• Secondary
• endometriosis
• adenomyosis
• chronic pelvic inflammatory disease
• pelvic adhesions

29
Primary dysmenorrhoea

• Onset a few years after menarche
• Regular cycles
• Pain for less than 2 days
• Cramping pain
• Nausea other GI symptoms
• radiation to thigh
• relieved after childbirth but may recur after
  some years

30
Dysmenorrhoea

• History
• Physical examination
• Is pelvic examination needed
• Recommended in all cases except in teenagers who
  are not sexually active with typical primary
  dysmenorrhoea

31
Dysmenorrhoea

• Investigations needed
• Ultrasound pelvis if
• clinical pelvic examination abnormal
• symptoms suggestive of secondary dysmenorrhoea
  but PV not conclusive or not possible
• Laparoscopy
• seldom needed

32
Dysmenorrhoea role of laparoscopy

• Subfertility
• Chronic pelvic pain
• Relieve the anxiety of patients
• Treatment
• endometriotic cyst
• medical treatment fail
• subfertility

33
Dysmenorrhoea

• Medical treatment for dysmenorrhoea
• Simple analgesics paracetamol NSAID
• indicated for primary and secondary dysmenorrhoea
  without associated subfertility or ovarian cysts
  
• Hormonal therapy as a second line when simple
  analgesia fails

34
Dysmenorrhoea

• Hormonal therapy
• Primary dysmenorrhoea
• combined OC pills (low EE)
• Endometriosis
• progestogen only
• combined OC pills (low EE)

35
Uterine fibroids

• Common
• 25-30 of women over 35
• Often asymtomatic
• Incidentally detected on pelvic ultrasound

36
Uterine fibroids

• When to refer
• symptoms related to fibroids
• size gt 12 weeks (palpable per abdomen)
• pain
• uncertain diagnosis ovarian cyst
• subfertility recurrent miscarriage

37
Uterine fibroids

• Symptoms related to fibroids
• menorrhagia
• irregular menstruation (only for submucosal
  fibroids)
• urinary (frequency retention)
• abdominal distention

38
Uterine fibroids

• How to follow up asymptomatic fibroids
• Ultrasound
• Usually no needed
• Check symptoms and uterine size clinically every
  6 months or ask patient to return if symptomatic

39
Uterine fibroids treatment

• Surgical treatment remains the mainstay
• myomectomy (laparotomy laparoscopy hysterocopy)
• hysterectomy
• Medical treatment with GnRH analogue
• shrink fibroids before surgery
• buy time before menopause
• Embolization inadequate evidence on
  effectiveness and safety

40
Uterine fibroids

• Post-myomectomy follow up
• fibroids can recur after myomectomy
• advice for pregnancy
• When
• Caesarean delivery needed
