ποΈ FREE MSRA PODCAST β Endometriosis Deep Dive
This is your audio flashcard for one of the most high-yield, complex gynaecological topics on the MSRA: Endometriosis.
π§ Key Learning Points
π Definition
β’ Chronic inflammatory condition where endometrial-like tissue grows outside the uterus
β’ Commonly involves ovaries, fallopian tubes, pelvic peritoneum
β’ Driven by oestrogen β causes pelvic pain and infertility
π Causes
Exact cause = unknown
But 4 key theories:
1οΈβ£ Retrograde menstruation
2οΈβ£ Genetic predisposition
3οΈβ£ Immune system dysfunction
4οΈβ£ Hormonal imbalances
π‘ Mnemonic: βReGIHβ β Retrograde, Genetics, Immune, Hormones
π Risk Factors
β’ Early menarche, short cycles (<27 days)
β’ Heavy/long periods
β’ Family history
β’ Nulliparity
β’ Low BMI, smoking
β’ Obstructed menstrual flow (e.g. hymenal abnormalities)
β’ White ethnicity
Group them: Cycle-related, Genetic, Structural, Demographic/Lifestyle
π Pathophysiology
β’ Ectopic tissue responds to hormonal cycle β bleeds monthly
β’ Blood has no exit β triggers inflammation, scarring, adhesions
β Leads to pain, organ dysfunction, fertility issues
π Symptoms
β’ Pelvic pain (chronic or cyclical)
β’ Dysmenorrhoea, dyspareunia, menorrhagia
β’ Infertility
β’ Others: bloating, fatigue, constipation, cyclical rectal bleeding, haematuria
π‘ Triad: Pelvic pain + Dyspareunia + Dysmenorrhoea
π Differentials
β’ Gynae: PID, fibroids, adenomyosis, ovarian cysts, ectopic, torsion
β’ GI: IBS, appendicitis
β’ Urinary: UTI, interstitial cystitis
π‘ Think multi-system when evaluating pelvic pain
π Epidemiology
β’ Affects ~10% of women of reproductive age
β’ 7.5-year average diagnostic delay
β’ Found in 30β50% of infertile women
β’ Variable symptoms β diagnosis often missed
π Investigations
β’ Pelvic exam (may be normal)
β’ TVUS β good for endometriomas
β’ Laparoscopy = π gold standard
β’ MRI β for deep lesions (bladder/bowel)
β’ CA-125: not specific
β’ In acute settings: bloods, swabs, pregnancy test
π‘ Normal scan in primary care β rule out endometriosis
β Refer if symptoms fit
π Management
Depends on fertility desires & severity:
π©Ί Medical:
β’ NSAIDs
β’ Hormonal therapy:
ββ COCP, progestins, GnRH agonists
ββ Levonorgestrel IUS
β Avoid hormonal suppression if trying to conceive
πͺ Surgical:
β’ Laparoscopic excision, adhesiolysis, cystectomy
β’ Hysterectomy (last resort)
π‘ Surgery can improve fertility in mild-moderate disease
πΆ Fertility:
β’ Controlled ovarian stimulation β IVF if needed
π NICE (2017):
Stepwise: Pain relief β Hormones β Refer for specialist/surgical care
π Prognosis & Complications
β’ Variable course
ββ Spontaneous regression in some
ββ Progression/recurrence in others
β’ 50% relapse after surgery
β’ Complications:
ββ Infertility
ββ Chronic pain & adhesions
ββ Depression
ββ Possible association with some ovarian cancers
ββ β Risk of IBD
