Q

What is a bimanual pelvic examination?

A

bimanual pelvic examination (BPE) is used to check a woman’s internal pelvic organs.

The health care provider inserts two fingers into the vagina and then places pressure with the other hand to the lower part of the belly.

Q

What is the RMI in gynaecology?

A

Risk of malignancy (RMI) in ovarian tumours

combines 3 pre-surgical features: serum CA125 (CA125), menopausal status (M) and ultrasound score (U).

The RMI is a product of the ultrasound scan score, the menopausal status and the serum CA125 level (IU/ml). RMI = U x M x CA125.

19
Q

RMI ranges?

A

RMI score greater than 200: high risk, with referral to specialist gynaecological cancer service, and staging CT advised

RMI score 25-200: intermediate risk, with MRI recommended to further evaluate the lesion

RMI score less than 25: low risk, with repeat clinical assessment advised, with MRI if ultrasound features are borderline 1

20
Q

What is included in the ultrasound segment of the RMI score?

A

Ultrasound result is scored 1 point for each of the following characteristics on US:

multilocular cysts (cysts with multiple lines of separation), solid areas, metastases, ascites and bilateral lesions.

21
Q

RMI = ultrasound score x menopausal status x ca-125 value (U/ml). True/false?

A

True

22
Q

Further radiology that can be used for investigation of ovarian cancer?

A

CT - to assess spread of cancer and operability

MRI - to characterise the ovarian cyst in a better way

23
Q

Ovarian sex cord-stroma masses?

A

Granulosa cell
Thecoma
Fibroma
Sertoli cell
Sertoli-Leydig
Steroid

24
Q

Ovarian germ cell masses?

A

Dysgerminoma
Yolk sac
Embryonal carcinoma
Choriocarcinoma
Teratoma

25
Q

Ovarian surface epithelium stroma masses?

A

Serous
Mucinous
Endometroid
Clear cell
Transitional cell

26
Q

What are functional (ovarian) cysts and features?

A

a fluid-filled sac within the ovary

Related to ovulation
Rarely more than 5cm diameter
Usually resolve spontaneously
May cause menstrual disturbance
Consider as a differential in acute abdomen as it may bleed or rupture
Often asymptomatic/incidental

27
Q

Functional cysts are basically enlarged Graafian follicles or corpeus luteum cysts. true/false?

A

True

28
Q

What are endometriotic cysts?

A

Endometriosis cysts ( endometrioma ) occur when sacs filled with endometrial-like tissue form in the ovaries.

Aka “chocolate cysts”

29
Q

Difference between endometriosis and endometriotic cysts?

A

Endometriosis is a condition in which the endometrium is found elsewhere than in the lining of the uterus.

Endometrioma (endometriotic cyst) is an ovarian cyst caused by endometriosis. Nicknamed “chocolate cyst”

30
Q

Features of endometriotic cysts?

A

Presents with:
Severe dysmenorrhea/premenstrual pain
Dyspareunia
Associated with sub fertility
Occasionally asymptomatic
Acute abdomen if ruptures

Examination:
Tender mass with modularity
Tenderness behind uterus

31
Q

What is a dermoid cyst?

A

A type of tumour that contains a cyst filled with tissues that are normally found in the outer layers of the skin, including sweat and oil glands.

These may also contain elements of hair and teeth.

32
Q

What is taken into consideration when treating benign ovarian tumours?

A

Symptoms, fertility and menopausal status

33
Q

Treatment options for benign ovarian tumours?

A

CONSERVATIVE

MEDICAL –GnRH analogues, OCP. Can be used for ovarian suppression.

SURGICAL – LAPAROSCOPIC/LAPAROTOMY
OVARIAN CYSTECTOMY
UNILATERAL OOPHERECTOMY
BILATERAL OOPHERECTOMY
PELVIC CLEARANCE

34
Q

What are borderline ovarian tumours?

A

Borderline ovarian tumors (BOTs) are abnormal cells or growths that develop in the tissue encapsulating an ovary.

While BOTs are not cancerous, they have the potential to develop into cancer. So removal would be advised

35
Q

Features of borderline ovarian tumours?

A

Growth much more controlled than cancer

Unlikely to spread

Even if spread – as implant rather than deeply invasive

Usually a better prognosis compared to ovarian cancer

Young women – unilateral cystectomy/oopherectomy with close follow up

Postmenopausal women – pelvic clearance

36
Q

What is pelvic clearance?

A

a major surgical procedure to treat cancer that has spread through the pelvis by removing multiple organs.

Typically, this means removing the lower bowel or rectum and the prostate or vagina. The bladder may also be removed.

37
Q

How many types of fibroid (leiomyomas) are there?

A

3

38
Q

What are the 3 types of fibroids?

A

Subserosal fibroids: These are the most common type. They grow on the outside of the uterus.

Intramural fibroids: These grow inside the muscular wall of the uterus.

Submucosal fibroids: These grow into the open space inside the uterus.

39
Q

Submucosal fibroids are usually benign. true/false?

A

True

SMOOTH MUSCLE TUMOURS

USUALLY, BENIGN

0.5% MALIGNANCY RISK

40
Q

Treatment options for fibroids?

A

CONSERVATIVE

MEDICAL MANAGEMENT – HORMONAL Mx for bleeding, GnRH agonists

Surgical management – myomectomy (surgical fibroid removal), hysterectomy (surgical removal of uterus)

Interventional radiology – UTERINE ARTERY EMBOLISATION

41
Q

Examples of GnRH agonists?

A

Buserelin
Gonadorelin
Goserelin
Histrelin
Leuprorelin
Nafarelin
Triptorelin

42
Q

Appearance of uterine fibroids on ultrasound?

A

Concentritic, solid, hypoechoic (dark grey) masses.

Fibroids are a benign growth of the myometrium

43
Q

Benign ovarian cyst appearance on ultrasound?

A

Uniform, smooth rounded dark fluid-filled bubbles on ultrasound.

If ovarian cyst > 5cm and symptomatic there is a chance it would become more serious and should be removed via laparoscopy

44
Q

Malignant ovarian cancer on ultrasound?

A

Papillary projections on ultrasound. Diagnostic of epithelial stromal tumour.

Wall projections that are at least 3mm in height perpendicular to wall.

More than 4 projections or projections involving more than 50% of internal cyst wall point to malignancy
