Endometriosis Flashcards
What is Endometriosis?
Condition where there is Ectopic endometrial tissue OUTSIDE uterus
What is Adenomyosis?
Endometrial tissue in myometrium (muscle layer of uterus)
What is the main age group for Endometriosis?
25-40 yrs
Is the pathophysiology of Endometriosis clear?
No
What is the Retrograde Menstruation theory for Endometriosis? (2 steps)
- Endometrial cells travel backwards from uterine cavity –> Fallopian tubes –> Pelvis / Peritoneum
- Endometrial cells seed + grow here
What is another theory for Endometriosis pathophysiology?
Endometrial cells travel through lymphatic system (same way as cancer spreads)
What is endometrial tissue sensitive to?
Oestrogen
During menstruation, what happens to the ectopic endometrial tissue?
Bleeds, just like normal endometrial tissue
What does the bleeding of ectopic endometrial tissue cause? (2 things)
- Pain
- Bloating / distension @ ectopic sites
What can repeated bleeding and inflammation at ectopic sites lead to?
Scarring –> Adhesions
When are the symptoms of endometriosis reduced? (2 things)
- Pregnancy
- Menopause
What are the RF for Endometriosis? (6 things)
- Early menarche
- FHx Endometriosis
- Short menstrual cycles
- Long duration of menstrual bleeding
- Heavy menstrual bleeding
- Defects in uterus / fallopian tubes
What are the CF of Endometriosis?
- Pelvic / abdominal pain (cyclic)
- Dyspareunia (pain @ intercourse)
- Dysmenorrhoea
- Infertility
- Dysuria / Dyschezia
- Cyclic bleeding @ other sites (e.g haematuria)
What examinations can you do for sus Endometriosis? (2 things)
- Bimanual examination
- Speculum examination
What might you find @ examination of sus Endometriosis? (3 things)
- Endometrial tissue visible in vagina (esp post fornix)
- Fixed retroverted cervix
- Tenderness in vagina / cervix / adnexa
What does an enlarged, tender, boggy uterus indicate?
Adenomysosis
What are some DDx that present similarly to Endometriosis? (4 things)
- PID
- Ectopic pregnancy
- Fibroids
- IBS
How does PID present similarly to Endometriosis? (3 things)
- Pelvic pain
- Dyspareunia
- Abn / heavy bleeding
How does Ectopic pregnancy present similarly to Endometriosis? (4 things)
- Pelvic pain
- Dyspareunia
- Abn / heavy bleeding
- Collapse
How does Fibroids present similarly to Endometriosis? (4 things)
- Pelvic pain
- Long duration of menstrual bleeding
- Heavy menstrual bleeding
- Bloating / feeling of a mass
How does IBS present similarly to Endometriosis? (3 things)
- Abd pain
- Dyspareunia
- Bloating
What is the GOLD standard investigation for sus Endometriosis?
Laparoscopy
What are the typical findings of Endometriosis on Laparoscopy? (4 things)
- Endometriotic lesions (see pic)
- Chocolate cysts (endometriosis of ovaries)
- Peritoneal deposits
- Adhesions

What are the benefits of doing a Laparoscopy for sus Endometriosis? (2 things)
- Take biopsy (for definitive dx)
- Surgically remove deposits (can improve symptoms)
What other investigation can be done for sus Endometriosis?
Pelvic US
(Usually unremarkable tho and will be referred to gynae for Laparoscopy)
What does NICE recommend instead of using a staging system for Endometriosis?
Detailed documentation of endometriosis
What are the 3 components of Mx of Endometriosis?
- Pain
- Hormonal
- Surgical
How do you manage the pain of Endometriosis?
Analgesia / NSAIDS (follow analgesia ladder)
What is a benefit of Hormonal Mx of Endometriosis?
Can be tried even before definitive Dx with laparoscopy
What are the options for Hormonal Mx of Endometriosis? (5 things)
- COCP
- POP (Norethisterone)
- Depo-Provera injection
- IUD (Mirena coil)
- GnRH agonists
How do COCP / POP / Depo / IUD work to manage Endometriosis? (3 steps)
- Suppresses ovulation
- Causes atrophy of endometriosis lesions
- Reduces symptoms
How do GnRH agonists work to manage Endometriosis? (3 steps)
- Induce menopause-like state
- Female sex hormones reduced
- Reduces symptoms
What are the side fx of using menopause-like inducing meds like GnRH agonists? (3 things)
- Hot flushes
- Night sweats
- Osteoporosis
What are the Surgical Mx options of Endometriosis? (2 things)
- Laparoscopy
- Hysterectomy
What can be done in Laparoscopic Tx of Endometriosis? (3 things)
- Excision
- Ablation
- Adhesiolysis
What is the benefit of Laparoscopic Tx over Hormonal Tx of Endometriosis?
Laparoscopic Tx can improve fertility
When is Hysterectomy a better option than Laparoscopic Tx of Endometriosis?
Beh relapses (which almost always occur after laparoscopic tx)
