Impact of haemostatic sealant versus electrocoagulation on ovarian reserve after laparoscopic ovarian cystectomy of ovarian endometriomas: a randomised controlled trial.

Abstract

To evaluate the effect of haemostatic sealant compared with bipolar coagulation on ovarian reserve after laparoscopic cystectomy for ovarian endometriomas. Patient-blinded, randomised controlled trial. University-affiliated tertiary hospital. Women aged 18-40 years with 3-8 cm unilateral or bilateral endometriomas. Ninety-four patients were randomised to receive haemostasis by the application of haemostatic sealant (n = 47) or standard care (n = 47). Primary outcome was the effect on the antral follicular count 3 months after the operation as it captures the effect on the ovary subjected to treatment. Secondary outcomes included the change in anti-Mullerian hormone, follicular-stimulating hormone and peri-operative outcomes including haemostasis, complications, pain, and satisfaction scores. A total of 94 patients aged 32.36 ± 4.92 years underwent laparoscopic cystectomy for ovarian endometriomas. The average diameter of the endometrioma was 4.21 ± 1.38 cm. The increase in antral follicle count of the affected ovaries at 3 months in the intervention group (+2.36 ± 0.37) was significantly (P = 0.013) higher than that in the control group (+1.08 ± 0.36). Repeated measures analysis of variance revealed significant effect with time (P < 0.001) and of interaction of group × time (P = 0.029) for affected ovary antral follicle count. No significant difference was noted between the two groups with regard to follicular-stimulating hormone, anti-Mullerian hormone, and other secondary outcomes. Applying haemostatic sealant after laparoscopic cystectomy of ovarian endometriomas produced a greater increase in antral follicle count 3 months after surgery compared with the control group. RCT: Haemostatic sealant in laparoscopic cystectomy of endometriomas increase in the antral follicle count after surgery.
