Ovarian Function After Use of Various Hemostatic Techniques During Treatment for Endometrioma

Brief summary (registry, in English)

Background: Endometriosis is defined by the presence of endometrial tissue outside the uterine cavity due to causes not yet fully elucidated. The disease affects approximately 2% of women of reproductive age and is associated with infertility. Approximately 17% to 44% of women with endometriosis exhibit endometrioma, or ovarian endometriosis. Laparoscopic cystectomy is currently considered the gold standard treatment for this problem, resulting in improvement of symptoms, a lower recurrence rate and a higher pregnancy rate among infertile patients. However, several studies have shown that this treatment is not free from risks because it is associated with reduction of the ovarian reserve due to accidental removal of ovarian cortex during stripping of the capsule or damage caused by the coagulation energy during hemostasis, even when performed by experienced surgeons. There is still controversy in the literature as to the cause of the reduction of the ovarian reserve, as the mere presence of endometrioma reduces ovarian function by itself. The aim of this study is to compare the effects of different hemostatic methods on the ovarian function of women subjected to laparoscopic surgery for ovarian endometrioma. Methods: Open-label randomized clinical trial to be conducted at Lauro Wanderley University Hospital from September 2017 to August 2020. Eighty-four patients will be randomly allocated to three groups according to the hemostatic technique used during laparoscopic surgery for ovarian endometrioma: bipolar coagulation, laparoscopic suture and hemostatic matrix. Ovarian function will be assessed by measuring serum anti-Mullerian hormone and follicle-stimulating hormone levels and by ultrasound antral follicle counts before surgery and 1, 3 and 6 months after surgery. The study was approved by the research ethics committee at the Medical Sciences Center, Federal University of Paraíba CAAE no. 71621717.9.0000.8069. Discussion: The present study intends to assess the ovarian function of patients with endometrioma subjected to laparoscopic surgical treatment, comparing different hemostatic techniques like bipolar coagulation versus suture versus hemostatic matrix with objective assessments of bipolar coagulation to avoid bias. Thus, the investigators expect to contribute data likely to dispel doubts on the subject.
