  1. what is endometriosis?
    presence and growth of tissue similar to endometrium outside the uterus
  2. on what 2 occasions does endometriosis regress? and why?
    • pregnancy
    • menopause
    • as it is oestrogen dependent and in these conditions, less oestrogen around
  3. what are 2 particular locations for endometriosis?
    • uterosacral ligaments
    • on/behing ovaries
  4. where are other occasional sites for endometriosis?
    • bladder
    • rectum
    • lung
    • abdominal wound scar
    • umbilicus
    • vagina
  5. what is the typical lesion in the ovary called?
    • endometrioma - accumulated altered blood which is dark brown
    • chocolate cyst
  6. what is the progression for endometriosis?
    • inflammation
    • progressive fibrosis
    • ADHESIONS
  7. what happens in the most severe form of endometriosis?
    • entire pelvis is FROZEN
    • pelvis organs are immobile by adhesions
  8. what is thought to be the main cause of endometriosis?
    retrograde menstruation
  9. how do more distant foci of endometriosis form?
    from mechanical, lymphatic or blood-borne spread
  10. what is the one main symptom of endometriosis?
    • CYCLICAL
    • chronic pelvic pain
  11. what are the main symptoms of endometriosis? (6)
    • dysmenorrhoea even before period starts
    • deep dyspareunia
    • infertility
    • dyschezia = pain on passing stools during menses
    • cyclical bladder (haematuria) or bowel symptoms - rectal bleeding
    • chronic pelvic pain
  12. why could endometriosis present acutely?
    rupture of chocolate cyst in ovary (endometrioma)
  13. what are the findings O/E of endometriosis
    • uterus is retroverted, fixed (due to adhesions)
    • nodules on uterosacral ligaments
    • tenderness, thickening behind uterus
  14. how is the diagnosis of endometriosis made?
    laparoscopy - visualisation and biopsy
  15. what can be seen on laparoscopy of endometriosis?
    • active lesions: red vesicles
    • less active: white scars or brown spots (powder burn)
  16. what indicates severe disease on laparoscopy?
    • extensive adhesions
    • endometriomata
  17. why is TVUS used?
    • exclude ovarian endometrioma
    • adenomyosis
  18. if there is evidence of deeply infiltrating endometirosis what Ix is done?
    MRI and maybe IVU
  19. what blood test may be raised in endometriosis but isn't specific?
    CA125
  20. what is differential diagnosis of endometriosis (5)?
    • adenomyosis
    • PID
    • chronic pelvic pain
    • other pelvic masses eg ovarian tumour
    • IBS
  21. what happens to endometriosis in over 50% of women?
    regresses or does not progress
  22. what are the 5 options for medical Rx of endometriosis?
    • analgesia: NSAIDs/complementary med - as some women don't like to take hormonal therapy
    • COCP
    • progestogens
    • GnRH analogue +- HRT addback
    • IUS
  23. how is the administration of COCP for endometriosis different for usual contraception?
    • often used back-to-back or tricycling
    • ie no break to reduce frequency of painful withdrawal bleeds
  24. how would GnRH analogues help in endometriosis?
    • induce menopausal state
    • lots of GnRH overstimulates pituitary so get downregulation of GnRH receptors
    • so the gonadotrophins and ovarian hormone production is therefore inhibited
  25. what needs to be done if want to use GnRH analogues for >6/12 and why?
    • due to reversible demineralisation of bones need to add HRT after 5 months
    • prevent bone loss
    • and reduce menopausal SE
  26. what type of Rx would women with endometriosis related pain and infertility usually go for and why?
    • surgery - destroy lesions
    • as improves conception rates
  27. if there is severe disease affecting fallopian tubes and pt is suffering from infertility, what is best Rx?
    IVF
  28. what are the 2 main surgical options for Rx of endometriosis?
    • laparoscopic laser ablation/diathermy +/- adhesiolysis

  29. when there is pain during intercourse, what is this called?
    deep dyspareunia (not position dependent)
  30. what happens to endometriosis over time?
    gets worse

    endometriosis
  33. what is Fitz-Hugh-Curtis syndrome?
    • rare complication of PID
    • gonorrhoea or chlamydia cause infection and inflammation in pelvis
    • can cause scar tissue to form on Glisson's capsule around the liver
    • so get RUQ pain worse on coughing or movement and referred to R shoulder

    • ovarian cyst/tumour
  52. what are 7 categories of dyspareunia?
    • congenital: vaginal atresia/septum
    • infection: PID

  56. how does the uterus typically feel with adenomyosis?
    tender and bulky
  57. which 5 categories of Ix do we do in pelvic pain?
    • bloods: FBC, pregnancy, G&S (in case something ruptures), CRP

    • laparoscopy
  58. which 5 conditions can laparoscopy diagnose/exclude?
    • endometriosis
    • adhesions
    • ectopic pregnancy

    • 2. endometriosis
  60. why do you get cyclical pain in endometriosis?
    • because deposits of endometriosis, whatever their location in the body
    • respond to ovarian cycle
    • bleeding from the deposits causes local irritation and inflammatory responses

    peritonism due to very irritant 'chocolate' material from the cyst
