The mainstay of endometrioma management, when treatment is required, is surgical. Although laparoscopy is considered to be the gold standard for endometriosis surgery, there is no clarity on the preferred laparoscopic technique, which may depend on whether the primary goalis treatment of infertility or pelvic pain, prevention of recurrence or preservation of ovarian reserve. The aim of this survey to assess the surgical practice of the members of the European Society for Gynaecological Endoscopy (ESGE) on the conservative management of endometiotic cysts in women of reproductive age. The current survey showed that practice for the conservative management of endometriotic cysts was that laparoscopy accounted for 84.9% of the cases, expectant management for 12.1%, and laparotomy for 3%. The preferred surgical approach was cystectomy in 69% of the cases, while the parameters that determined the preferred surgical method were the diameter of the cyst (62%) and the bilaterality or non-location (53%). The type of energy used was in most cases bipolar (83%), 71.4% of surgeons did not reconstitute the ovary and 41% of responses included the administration of adhesion barrier agents. The primary surgical end-point was ovarian reserve (50%), which was tested preoperatively in 51.8%, mainly with an anti-mullerian hormone. In case of an incidentally deep-infiltrating endometriosis, 55.4% of the responses included concomitant treatment thereof, while 71% of the participants considered that a "pelvic surgeon", who could more effectively treat co- existing pelvic and intestinal disease, should be the ideal one to effectively manage endometriosis. The majority of participants (74%) in this survey consider that there is insufficient scientific evidence regarding the conservative management of endometriotic cysts. The treatment of ovarian endometrioma should be individualised, taking into consideration not only the relief of symptoms, pregnancy rates or recurrence rates, but also ovarian function and reserve after surgery.
