epithelial ovarian cancer

can also cause infertility

3
Q

A

erythematous, petechial lesions on peritoneum
thick, scarred surrounding peritoneum
lesions/endometriomas (chocolate cysts) on ovaries
adhesions

10

MC site of endometriosis is

A

The ovaries

11
Q

How do you treat mild endometriosis

A

expectant management

NSAIDS +/- OCP (can skip menses all together by stringing packs)

12
Q

How do you treat mod-severe endometriosis

A
OCP (string)- can atrophy endometrium
Progestins (PO, IM, IUD)- prevent endometrial growth 
GnRH agonists (Depot Lupron) suppress estrogen/progesterone
13

A

40-50% pregnancy rate after d/c

decrease risk of ovarian cancer

16
Q

What are uterine fibroids

A

proliferation of smooth muscle cells in uterine wall

made up of collagen, smooth muscle, and elastin, surrounded by pseudocapsule

17
Q

What group of women typically gets uterine fibroids

A

20-25% in women of child-bearing age
50% of populaiton have them by age 50
Seen earlier and grow faster
2-3x MC in black women

18
Q

What is the implicated etiology of uterine fibroids

A
  • Estrogen; myomas have higher concentration of estrogen receptors= increased production of extracellular matrix
  • Progesterone increases mitotic activity, suppresses apoptosis
19
Q

How can you classify uterine fibroids

A

Submucosal: just beneath endometrium (more inwards)
Subserosal: serosal surface (more outwards)
Intramural: w/in uterine wall

20
Q

Which uterine fibroids are associated with infertility

A

Submucosal- impinge uterine cavity

also increase surface area of endometrium and also cause menorrhagia

21
Q

What are symptoms of uterine fibroids

A

pain (contractions, dyspareunia) 
pelvic pressure (mass effect) 
infertility (submucosal) 
spontaneous abortion
22

uterine enlargement
irregular shape
mass (NOT fluctuant)

23

MRU

28
Q

How does Depot Lupron treat uterine fibroids

A

decreases fibroid size (bc they are associated w/ estrogen)
also helps improve anemia before, and decrease blood loss during surgery
DO NOT USE >6 months

29
Q

Who can use steroidal therapies to Tx uterine fibroids

A

prolonged, heavy menses

NO submucosal fibroids

30
Q

Who can take Lysteda and how does it work

A

prolonged, heavy menses W/O submucosal fibroids
PO anti-fibrinolytic for menorrhagia (decrease blood loss, little evidence on fibroid effects)
USE ONLY during menses, two 650mg tab BID (total 1300)

31
Q

What surgical option for uterine fibroid removal is good for preserving Fertility and the uterus

A

-Myomectomy- on intramural, subserosal, and pedunculated fibroids (20-50% recurrence)
but, delay pregnancy 3-6 mo to avoid uterine rupture and c-section
-Hysteroscopy- submucosal fubroids. has risk of fluid overload and hyponatremia

32
Q

Wat is a laparoscopic myomectomy

A

robot assistance myomectomy depending on number and size of fibroids
Complications: hemorrhage, re-op, adhesions

33
Q

What uterine fibroid patients are candidates for abdominal/mini-laparotomy myomectomy

A

those with CI to laparoscopy (cardiopulmonary dsease)
if fibroid size doesn’t allow laparoscopic
Hx of pelvic or abdominal radiation
Severe hip dz

34
Q

How do you perform a hysteroscopy

A

give a non-iodine solution to distend (1.5% glycine or 3% sorbitol)
use a heated loop to resect the fibroid
can be done outpt, can return to normal activity in 1-2 days, sex in 1 month

35
Q

What is endometrial ablation

A

min invasive method to preserve uterus, takes 2 min.
done outpt. at any time in menstrual cycle (general anesthesia or cervical block)
Admin CO2 for distention
Tx for menorrhagia w/o major uterine distortions (best if <9cm)

36
Q

If you have had an endometrial ablation, can you have kids?

A

You should NOT bear children, but use contraceptives because if you do get pregnant it can implant into the muscle wall (placenta accreta)

37
Q

Con’s to endometrial ablation include

A

must first remove polyps and submucosal fibroids (does not distort the uterus)
doesn’t address fibroid Sx
50% experience amenorrhea

38
Q

What is uterine artery embolization

A

arteriogram to ID blood supply to fibroid
cath goes into uterine artery and embolizing agent flows in
Preserves the uterus NOT fertility!

39
Q

What pts are candidates for uterine artery embolization

A

If they do not want kids
