- If stable, urgent TVUS
- If unstable, urgent laparoscopy
Management of ovarian cysts - premenopausal women?
Re-scan in 6 weeks.
If cyst <5cm and asymptomatic – no surgical intervention
If cyst >5 cm, symptomatic or features a dermoid/endometriosis – laparoscopic ovarian cystectomy
o Do not spill cyst contents (can cause peritonitis or can disseminate an early ovarian cancer)
Monitor with yearly USS
Management of ovarian cysts - postmenopausal women - low RMI, simple, <5cm cyst and normal Ca125?
o Follow up USS and CA125 every 4 months
o If no change after 1 year then discontinue monitoring
o If change and RMI still low or woman requests removal = laparoscopic oophorectomy.
Management of ovarian cysts - postmenopausal women - moderate RMI (25-250)?

Epidemiology of endometriosis?
• Incidence of endometriosis:
- General population = 10-15%
- Dysmenorrhoea = 40 – 60%
• Most common gynaecological condition after fibroids.
Definition of endometriosis?
- Endometriosis is the presence of endometrial like tissue outside the uterine cavity.
- It is oestrogen dependent and therefore mostly affects women during their reproductive years.
Locations of endometriosis?
- Common = pelvis. • Pouch of douglas • Uterosacral ligaments • Ovarian fossae • Bladder • Peritoneum - Rare = lungs, brain, muscle, eye
Definition of adenomyosis?
Adenomyosis is invasion of myometrium by endometrial tissue, causes inflammation, pain and adhesions.
Cause of chronic pelvic pain, dyspareunia and infertility
Risk factors of endometriosis?
o Early menarche, late menopause, long menstrual flow
o Obstruction to vaginal outflow
o Genetics – risk when 1st degree relative is 6x more
Protective factors of endometriosis?
o Multiparity
o Use of OCP
Aetiology of endometriosis?
Retrograde menstruation with adhesion, invasion and growth of the tissue (most popular)
During menstruation, endometrial tissue spills into the pelvic cavity through the fallopian tubes (retrograde menstruation) and then implants and becomes functional, responding to the hormones of the ovarian cycle.
Metaplasia of mesothelial cells
Systemic and lymphatic spread.
Endometrial tissues transported through the body by lymph or venous channels.
Explains the rare cases of distant sites for endometriosis
Sites of endometriosis?
o Peritoneum, pouch of Douglas (POD), ovary/tubes, ligaments, bladder and myometrium
Symptoms of endometriosis?
Severe dysmenorrhoea
Cyclical - tends to occur prior to period and exacerbated by menstrual flow
Deep dyspareunia
Affects QoL
Involvement of uterosacral ligaments
Heavier bleeding
Chronic Pelvic pain
Cyclical (menstrual cycle) or continuous (adhesions/chronic inflammation)
Infertility
Adhesions and tubal/ovarian damage can affect ovulation
Dysuria
Involvement/invasion of bladder/bladder peritoneum
Dyschezia (pain on defecation) and cyclic pararectal bleeding
Rectovaginal nodules with invasion of rectal mucosa
Chronic fatigue, bloating, low back pain
Signs of endometriosis?
- Often normal
- Speculum= visible lesions in vagina/cervix
- Bimanual=fixed retroverted uterus (classic sign)
- Adnexal masses (endometriomas – ‘chocolate cysts’ on ovaries) or tenderness.
- Nodules/tenderness over uterosacral ligaments.
Investigations and diagnosis of endometriosis?
Transvaginal USS
- Identifies endometriosis + deep into bowel//bladder & endometriomas
- If not appropriate, can use transabdominal USS
Laparoscopy with biopsy (gold standard)
o Histological verification
Positive is confirmative
Endometriomas >3cm should be resected to rule out malignancy (rare)
o If normal – woman does not have endometriosis
o Avoid within 3 months of hormonal treatment (leads to underdiagnosis)
o Signs present – red dots, black ‘powder burn’ dots, large raised red/black vesicles, white area of scarring with surrounding abnormal blood vessels
Further investigations used in endometriosis?
• Pelvic MRI
- Used to assess extent of deep endometriosis involving bowel/urinary tract
Grading system of endometriosis?
rASRM grading: - Location - Size - Depth - Adhesions - Stages • 1 = Minimal endometriosis (1-5 points) • 2 = Mild endometriosis (6-15 points) • 3 = Moderate endometriosis (16-40 points) • 4 = Severe endometriosis (>40 points)
Management of endometriosis - analgesia?

Management of endometriosis -hormonal treatments?
- COCP
• Cyclically or continuous PO/IM/SC
• Effect = ovarian suppression
• SE = headaches, N&V, diarrhoea, stroke. - Medroxyprogesterone acetate or other progestagens
• Effect = ovarian suppression
