A randomised controlled trial assessing ovarian reserve after laparoscopic ethanol sclerotherapy of ovarian endometrioma compared to standard treatment of surgical excision of endometrioma. Secondary outcomes will include endometrioma recurrence, symptomatology and inflammatory environment.
Participants with endometrioma(ta), identified on imaging, who are opting for surgical management of endometriosis will be randomly allocated to laparoscopic ethanol sclerotherapy of endometrioma or laparoscopic surgical excision of endometrioma(ta). Any concurrent endometriosis identified at surgery will be excised as per routine care. Ovarian reserve will be assessed by serum anti-Mullarian hormone (AMH) and antral follicle count (AFC), recurrence will me assessed by transvaginal ultrasound, symptomatology will be assessed by EHP-30 questionnaires and changes in inflammation assessed in serum and endometrial biopsy. Each participant will be followed up for a total of 24 months from surgery.

RECRUITINGOvarian Reserve
To determine the statistical difference in ovarian reserve pre- and post- treatment (as measured by serum AMH at 3, 6, 12 and 24 months and antral follicle count at 6, 12 and 24 months) in participants randomised to receive laparoscopic ethanol sclerotherapy or laparoscopic excision of endometrioma
Time frame: 24 months
Endometrioma recurrence
To determine if laparoscopic ethanol sclerotherapy for ovarian endometrioma alters recurrence of ovarian endometrioma (as measured by TVUSS at 6, 12 and 24 months) as compared to laparoscopic excision of endometrioma
Time frame: 24 monhts
Symptomatology
To determine if laparoscopic ethanol sclerotherapy for ovarian endometrioma affects symptomatology (as recorded by EHP-30) as compared to laparoscopic excision of endometrioma at 3, 6, 12 and 24 months
Time frame: 24 monhts
Inflammation
To determine if laparoscopic ethanol sclerotherapy for ovarian endometrioma alters the inflammatory environment (as measured in blood at 3, 6, 12 and 24 months, and endometrial biopsy at 6 months) as compared to laparoscopic excision of endometrioma
Time frame: 24 monhts
