When is diagnostic laparoscopy recommended in the management of endometriosis?

Diagnostic laparoscopy is NO longer the gold standard for diagnosis of endometriosis

Perform it if:

1) Normal US scan or MRI scan
and/or
2) Medical treatments have been ineffective or inappropriate

What are the recommended medical treatment options for endometriosis-associated pain?

1st line:

NSAIDs
Combined hormonal contraceptives
Progestogens

2nd line:

GnRH agonists. If above are ineffective. Consider combined add-back therapy to prevent bone loss & hypoestrogenic sx
GnRH antagonists

3rd line:

Aromatase inhibitors. Give if pain is refractory to medical or surgery treatment. Can give alongside the above

What are the recommended surgical treatment options for endometriosis-associated pain?

May consider excision instead of ablation of endometriosis
Don’t perform LUNA (Laparoscopic Uterosacral Nerve Ablation)
Can do PSN (Presacral Neurectomy) for midline pain as an adjunct to conventional surgery

PSN SEs - bleeding, urinary urgency, constipation, painless 1st stage of labour

Offer post-op hormonal treatment to improve the immediate outcome of surgery and reduce chance of relapse/endometriosis-associated dysmenorrhoea:

1) Mirena IUS 52mg
OR
2) COCP for at least 18-24 months

What are the medical treatments offered to adolescents with endometriosis?

1) COCP or progestogens - 1st line

2) NSAIDs - 2nd line

3) GnRH agonists with combined add-back therapy - if laparosocpy has confirmed endometriosis + hormonal treatment has failed. Give for up to 1 year

If discussing cystectomy for ovarian endometriomas then discuss potential detrimental effects on ovarian reserve and future fertility

What is the medical management of post-menopausal women with endometriosis?

1) Aromatase inhibitors - especially if surgery isn’t feasible

Even with women who have had a total hysterectomy + BSO (surgical menopause) - give combined HRT at least until the age of natural menopause
