>80
Fatigue, sob
Findings on exam for heavy bleeding
Mass - smooth/irregular
Vaginal tumour
Cervix - polyp, tumour, inflammation
Tender/excitation - adenomyosis, endometriosis
Causes of heavy bleeding
1 = DUB - no other abn, vessel contraction abn
Med problem - SLE, hypothyroid, liver disease, cancer
FIGO classification : PALM-COEIN
Polyp - endom, cervical. Intermenstrual or postcoital, no pain
Adenomyosis - dyuria , bulky tender uterus
Leiomyoma - mass, heavy bleed, shrink after meno
Malignancy or hyperplasia - vaginal, endometrial or cervical
Coagulopathy - vwf, anticoagulants, thrombocytopoenia, leukaemia
Ovarian - pcos
Endometriosis
Iatrogenic - contraception, IUCD
Not known - dub
Investaigiaons for heavy bleeding
Pregnancy
FBC, clotting and vwf, hormones (PCOS), TFT
Smear, swabs
TVUS if mass, pharm failed, risk factors
Endometrial pipelle biopsy if >45yo and persistent
Hysteroscopy and biopsy if pathological or inconclusive US
MAnage heavy bleeding and ADRs - medical
1 - levonorgestrel releasing IUS: shrinks fibroid, thins endom, 5yy, contraceptive
- ADR - progesterone ADRs, 6m of irregular bleeding
2 - antiifibrinoltics inhibit tPA so less plasminogen activation and less fibrinolysis - clot stabilissied
- tranexamic acid CI VTE, ADR tinnitus, rash, nausea
- mefanamic acid (also NSAID) CI ulcer, ADR GI, headache
- COCP - decrease gonadotrophins
3 - progesterone - norethisterone (short term), depo or implant
Surgical management of heavy bleeding
1 - endometrial thermal ablation - but can burn through to bladder and can regrow

Tender on exam
Discharge
Fever
New onset
Polyps sx as well as bleeding
Not usually painful
Intermenstrual

Gold standard investigation for endometriosis
Diagnostic/explorative laparoscopy
7 RF for endometrial cancer
Too much oestrogen: - nulliparity - early menarche - late menopause - pcos Obesity Family history of breast ovarian or colon cancer Diabetes
Cancer most linked to endometrial
Colon - HNPCC
Why are BMI and PCOS risk factors for endometrial cancer
Obese - increased peripheral aromatisation of androgens to oestrogens. 2x risk >25, 3x risk >30
PCOS - loner anovulation so less progesterone to counteract oestrogen
Staging of endometrial cancer
FIGO staging: 1 - uterine body 2 - uterine body and cervix 3 - outside uterus but in pelvis 4 - local/regional spread of tumour (bowel, bladder etc)
Inv endometrial cancer
TVUS for thickness >4mm
Biopsy with hysteroscopy (visualise) or as outpatient bedside
CT/MRI for staging
Surgery for endometrial cancer
TAHBSO
RT as adjuvant to prevent recurrence or external beam to control bleeding if unfit for surgery

4 types of fibroid
Subserosal (visceral)
Intramural
Submucosal (under endometrium)
Pedunculated
RF for fibroid
Age
Afrocaribbean
FHx
Oestrogen - pregnancy and COCP
Presentation of fibroids - 4
Menorrhagia - heavy and pronged, not intermenstrual
Pain - from pedunculated torsion or red degeneration (thrombus)
Mass effect - pressure on bladder
Infertility - distort cavity nd prevent implantation
Manage fibroids
None if symptoms not too bad
Med
- GnRH analogue or ullipristal acetate (selective progesterone receptor modulator) for 3-6m before surgery to shrink and induce amenorrhoea. Ullipristal acetate needs regular LFTs and FBCs
Surg
- uterine artery embolisation (v painful post op, can cause infected necrotic uterus)
- myomectomy (hysteroscopy or laparotomy) - best for future pregnancy but will need c section if uterus breached
- hystorectomy
Fibroids in pregnancy
Red degeneration:
2nd trimester - grow, can get thrombus of vessels, causing venous engorgement and inflammation = abdo pain, vomiting, low grade fever and localised tenderness
Will resolve in 4-7d with rest and analgesia
Fibroid after menopause
Most regress
Can become sarcoma = pain, malaise, bleeding, grow
Causes of intermenstrual bleeding
Cervical polyp, cancer of ectropion
Trauma or abrasion - post coital
Causes of post menopause bleedin
endometrial - polyp, cancer, hyperplasia
Cervical - polyp, cancer
Vulval cancer
What is endometriosis nd adenomyosis
Endo - endometrial tissue outside uterus
Adeno - endometrial tissue in myometrium
3 causes of endometriosis
Retrograde menstruation - adherence, invasion and growth
Impaired immunity
Metalasia of mesothelium cells
Inv endometriosis
TVUS for ovarian cysts
MRI if bowel symptoms to map extent
Diag - laparoscopy with biopsy - deep infiltrating lesions, do 3m after stopping hormones
Cells in cervix
Endocervix canal = mucous columnar epithelium
Vaginal cervix = squamous epithelium
Junction = transitional zone = predisposed to malig
What is ectropion and treatment
Extension of mucous columnar endocervix epithelium into ectocervix - prone to bleed, infection, mucous
Extends under hormones - puberty, pregnancy, COCP
No treatment necessary but can treat by removing hormonal contraception or diathermy
Manage cervical polyps
Post coital bleeding/discharge
If young, avulsed
Older - TVUS +- hysteroscopy to exclude interuterne polyp
Caus of cervicitis
Follicular or mucopurulent
Chlamydia, gonococci or herpes
What is CIN and different stages and management
Dyskaryosis of cervical tissue - pre-invasive
CIN1 - lower 1/3
- most will regress spontaneously
CIN2 <2/3
CIN3 >2/3
- less likely to regress, more likely to progress to invasive squamous cell cancer and quickly in younger women
Smear : CIN2-3:
Inflammatory - repeat in 6m, do swab, colposcopy if 3x abnormal
Borderline dyskaryosis = HPV test. If pos = 6 monthly colposcopy, LLETZ if persistent
If neg = 3y screening
If mod or severe dyskaryosis = colposcopy + LLETZ, then smear and HPV test in 6m. Pos = colp again
Suspected invasion or abnormal glandular cells (adenocarcinoma of cervix) = urgent colposcopy
Colposcopy = visualise transformation zone, give acetic acid which is taken up by neoplastic cells = white = abnormal, then do punch biopsy. Also look for microinvaion - vascular abnormalities
Inv CIN in pregnancy
Colp but no LLETZ
- definitive treatment 12w postpartum
Complications of Lletz
Haemorrhage
Infection
Vasovagal, anxiety
Cervical stenosis
What is related to CIN but not cancer
Cervical glandular intraepithelial neoplasia
Also HPV risk
Less visible, has skip lesions
LLETZ or cone biopsy or hysterectomy
