A

Diagnosis: Clinical exam, Ultrasound, Hysteroscopy, Laparoscopy.

Q

Tx of fibroids

A

Myomectomy
uterine artery embolisation
Hysterectomy

Q

What is Endometriosis?

A

Endometrial type tissue outside the uterine cavity, Common sites = ovary, pouch of Douglas (rectouterine pouch), pelvic peritoneum, May be asymptomatic and resolve without Rx. During menstruation this ectopic tissue behaves the same as endometrium and bleeds.

(PELVIC PAIN BEFORE AND DURING MENSTURATION, IRREGULAR UTERINE BLEEDING, POST-COITAL BLEEDING, DYMENORRHOEA.)
REDUCED FERTILITY, DYSPARENURIA, SHORTER CYCLE LENGTH, MENORRHAGIA, USE OF OCP INCREASES RISK OF ECTROPION, FHX OF CERVICAL CANCER, AGE OF FIRST SEXUAL INTERCOURSE, SMEAR HX
Signs: Tender nodules in rectovaginal septum, Limited uterine mobility, Adnexal mass.
SX: FIXED RETROVERTED UTERUS, ADNEXAL MASS, THICKENING OF UTEROSACRAL LIGAMNENTS, POSSIBLE CYSTIC SWELLINGS

Q

stages 1-4 of endometriosis

A

1 - patches, surface lesions or inflammation on or around organs on the pelvic cavity,
2 - widespread, infiltrating pelvic organs,
3 - peritoneum, scarring and adhesions,
4 - infiltrative and affecting many pelvic organs and ovaries,often anatomical distortion and adhesions.

19
Q

ENDOMETRIOSIS - Diagnosis/ Ix

A

Laparoscopy, MRI, pelvic exam. Bloods (FBC - anaemia, TFT’s - hypothyroidism, CLOTTING- abnormality may lead to increased blood loss)

20
Q

Complication of an exploratory laproscopy?

A

Bowel perforation, major vessel perforation

21
Q

ENDOMETRIOSIS - Mx

A

Medical: Progesterone = oral/injection/Mirena, Combined pill, GnRH analogues
Surgical: Excision of deposits from peritoneum/ovary, Diathermy/laser ablation of deposits, Hysterectomy/oophorectomy
SURGICAL EXCISION, COCP, POP, GnRH ANALOGUES

22
Q

What is Adenomyosis?

A

Endometrial tissue found deep in myometrium, Thickened wall of uterus can be mistaken for fibroids

23
Q

sy/sx for ADENOMYOSIS

A

menorrhagia, bulky tender uterus, dysmeorrhea

24
Q

Ix for ADENOMYOSIS

A

Usually normal Us, Laparoscopy, Hysteroscopy, Histology of uterine muscle = not endometrial biopsy

25
Q

tx for ADENOMYOSIS

A

Hysterectomy (may partially respond to hormones)

26
Q

Endometrial Polyps

A

Overgrowth of endometrial lining can lead to formation of pediculated structures called polyps which extend into endometrium

27
Q

dx and tx of endometrial polyps

A

US, hysteroscopy, mostly benign, Polpectomy

28
Q

Mx of heavy menstrual bleeding…

A

hx, pelvic examinaiton, clotting profile, thyroid function, uss, laparoscopy then tx depending on QOL impact, pathology, fertility, prefrences.
tx = nsaids (naproxen), tranexamic acid, coco, pop, iud.

29
Q

Define (DUB) Dysfunctional uterine bleeding

A

Abnormal bleeding but no structural/endocrine/neoplastic/infectious cause found for complaint, Subjective – 50% women who complain of heavy periods actually only lose <80ml per cycle, 50% hysterectomies for menorrhagia are because of DUB

30
Q

Medical tx to control DUB

A

Mefenamic acid (prostoglandin inhibitor) - reduces blood loss, suitable for those trying to conceieve.
Tranexemic acid (antifibrinolytic) - reduces blood loss
GnRh Analogues
Combined contraceptive pill (COCP)makes periods lighter, regular and less painful
Oral Progesterone - regulates cycle more

31
Q

Surgical tx OF DUB

A

Endometrial abalaiton - permenant destruction of the endometrium to below basal layer, Can use diathermy/thermal balloon, Treatment done through cervix, No effect on ovarian hormones/bladder, 60% will have no periods.
Hysterectomy - surgical removal of the uterus, abdominal or vaginal, laproscopic, (total = cervix and uterus removed) (wertheims = total + salpingo-oophorectomy)

32
Q

hysterectomy complications

A

infection/DVT/bladder/bowel/vessel injury/ altered bladder function / adhesions

33
Q

what is FIGO?

A

Classification of Abnormal Uterine Bleeding

34
Q

age predictors of the cause of menstrual disorders

A

• Early teens: Anovulatory cycle = menstrual cycle without release of oocyte, Congenital anomaly
• Teens – 40: Chlamydia, Contraception related, Endometriosis/adenomyosis, Fibroids, Endometrial or cervical polyps, Dysfunctional bleeding
• 40-menopause: Perimenopausal anovulation, Endometrial cancer, Warfarin, Thyroid dysfunction
ALWAYS CONSIDER PREGNANCY
ALWAYS LOOK AT THE CERVIX

35
Q

Ix to do for these disorders in general

A

Full blood count if menorrhagia, Endometrial biopsy, Chlamydia, Thyroid/coagulation if other symptoms, Pregnancy test, TV (trans-vaginal) ultrasound, Hysterectomy, Laparoscopy.
FBC, BIOPSY OF ENDOMETRIUM, PREGNANCY TEST, TVUSS, HYSTEROSCOPY, LAPAROSCOPY.

36
Q

what is Amennorhea and what are its causes?

A

infrequent or very light periods, causes: Life changes:stress, eating disorders/malnourishment, obesity, Intense exercise, Hormones:POP, Mirena, depot injection, Primary ovarian insufficiency, Polycystic ovarian syndrome, Hyperprolactinemia (elevated levels of prolactin in the blood), Prolactinomas (adenomas on the anterior pituitary gland), Thyroid disorders (Graves’s disease), Obstructions of the uterus, cervix, and/or vagina, Investigate and treat the cause.

37
Q

What is Polycystic Ovary Syndrome?

A

Polycystic ovary syndrome (PCOS) is a complex condition of ovarian dysfunction thought to affect between 5-20% of women of reproductive age.

38
Q

sy/sx OF PCOS

A

subfertility and infertility, menstrual disturbances: oligomenorrhea and amenorrhoea, hirsutism, acne (due to hyperandrogenism), obesity, acanthosis nigricans (due to insulin resistance).
(OLLIGOMENORRHAGIA, MENORRHAGIA, ERRATIC PERIODS)

39
Q

DDX for PCOS?

A

Hypothryroidism, endometriosis, coagulopathy, uterine polyps, dysfunctional uterine bleeding.

40
Q

questions to ask pt with PCOS to differentiate betweenm the ddx?

A

bleeding regularlity, bleeding from other places, fhx of coagulopathy, any sy of hypothyroidism (weight gain, lethargy, constipation). Hirsutism, acne, DM? dysmenorrhea? dysparenuria?

41
Q

Ix for PCOS

A

PELVIC USS: multiple cysts on the ovaries
BLOODS - LH:FSH RATIO, INCREASED SERUM ANDROGEN INDEX, DECREASED SEX HORMONE BINDING GLOBULIN, INCREASED PROLACTIN, DECREASED HB DUE TO MENORRHAGIA, (FSH, LH) prolactin, TSH, and testosterone are useful investigations: raised LH:FSH ratio is a ‘classical’ feature but is no longer thought to be useful in diagnosis. Prolactin may be normal or mildly elevated. Testosterone may be normal or mildly elevated - however, if markedly raised consider other causes. check for impaired glucose tolerance.

42
Q

Tx for PCOS

A

Lose weight, COCP, POP, metformin, clomiphene (induces ovulation), Mirena IUS

43
Q

What are 2 long term sequalae of PCOS?

A

infertility, T2DM, increased risk of endometrial hyperplasia and endometrial carcinoma, increased risk of CHD.

44
Q

questions to ask to confirm or refute fibroids?

A 
hx if miscarriage, increased urinary frequency
infertility
change in bowel habit
post-coital bleeding?
dyspareunia?
