Uterine Leiomyoma Flashcards
(19 cards)
Definition
Gynecological tumor
Is leiomyoma benign or malignant
benign
Where does it originate
In the smooth muscle cells of the myometrium
Pathogenesis
- Hormone dependent
- Estrogen and Progestin receptors
- High estrogen cause fibrinoid enlargement
- First trimester fibrinoid enlarges
- Shrinks after puerperium
- Some dec in size during pregnancy due to prgestin
- Shrink after menopause
- Regrowth after hormonal therapy
Risk factors
- Black/African women
- Nulliparity
- Early menarche
- Inc frequency of menses
- Dysmenorrhea
- Heredity
- Hormonal drugs
- Age
Diet

- Ultrasound (high sensitivity)
- MRI (most accurate )
Expectant management
Asymptomatic patients and premenopausal women
Medical therapy
- GnRHa
- Mifepristone
How does GnRHa work?

Hot flashes, sleep disturbances, vaginal dryness, myaligia, arthralgias, impairment of moof and cognition, bone loss
How does Mifepristone work?
It is a progesterone receptor modulator. decreases the PR in the myometrium and leiomyoma
What is the dose of Mifepristone?
2.5mg daily for 3-6 months
Surgical treatment?
- Hysterectomy
- Myomectomy
What is used to remove submucosal leiomyomas?
Hysteroscopy
Laparoscopy?
Diagnosis of subserous fibroids and intramural leiomyoma and treat uterine fibroids
Advantages of robotic assisted laparoscopy?
- shorter learning curve
- 3D
- inc dexterity
- precise
When do you do an abdominal myomectomy?
- Large no of fibroids
- Large diamater >10cm
- Cancer is suspected
- Special site fibroids
- Severe pelvic adhesions
