Q

A 33-year-old lady presents to the gynaecology clinic with dysmenorrhoea and menorrhagia. On questioning, she also reports dyspareunia and an inability to conceive for the last 3 years.

A transvaginal ultrasound scan is normal and she, therefore, undergoes a diagnostic laparoscopy that reveals endometriosis.

Which of the following treatment options would be most appropriate?

A

Laparoscopic diathermy and adhesiolysis

This patient has infertility that is likely secondary to endometriosis. The only treatment option that has been shown to improve fertility in endometriosis is surgery. Laparoscopic diathermy and adhesiolysis is a procedure that removes the endometrial deposits and adhesions from the pelvic cavity

49
Q

fribroids tx

A

LNG IUS - not if
LNG-IUS is often the 1st-line treatment; however in this case where the patient has several large pedunculated submucosal fibroids there will be uterine distortion making the insertion of an intrauterine system inappropriate
COCP - This would be a 2nd-line treatment option. However, its use holds an unacceptable health risk (UK Medical Eligibility Criteria for Contraceptive Use category 4) as this lady is aged over 35 and smokes more than 15 cigarettes a day. Tranexamic acid or NSAIDs are other 2nd-line options, but are not choices here

Oral norethisterone

This is the correct answer. It is a 3rd line option when the above treatments are deemed unsuitable, such as in this case

surgical
Myomectomy involves removing the fibroid from the uterine wall, and is generally fertility-sparing.

Ablation involves using a laser or radiofrequency(generates heat) to induce necrosis of the fibroid, and so the dead vessels no longer bleed.

Uterine artery embolisation may provide a targeted degeneration of the fibroid. This may also preserve fertility.

Hysterectomy involves removing the uterus. It is obviously extremely effective but will not preserve fertility.
