The study of ovarian reserve function affected by different haemostasis methods during ovarian endometriosis cysts excision

Objective To investigate the effects of two different hemostatic methods(bipolar electrocoagulation and suture) on ovarian reserve function in patients with endometriosis.Methods Sixty patients who underwent laparoscopic surgical treatment for ovarian endometriosis cysts were divided into bipolar electrocoagulation group and sutured group(n=30 in each group).The average contents of anti-mullerian hormone(AMH),follicle-stimulating hormone(FSH),luteinizing hormone(LH),estradiol(E2),antral follicle count(AFC),and peak systolic velocity(PSV) were compared in electrocoagulation group and suture group.Results For the sutured group,the levels of E2,AMH,FSH,AFC and PSV had no signifcant discrepancy(P0.05).For the electrocoagulation group,the levels of E2,AMH,AFC and PSV decreased signifcantly after operation,while the levels of FSH increased signifcant(P0.05).For the level of LH,there was no signifcantly discrepancy between two groups(P0.05).The decreases of E2,AMH,AFC and PSV in the bipolar electrocoagulation group at 1 and 6 months postoperatively were more signifcant than those in the sutured group(P0.05).And the level of FSH increased signifcantly in the bipolar electrocoagulation group compared to the sutured group(P0.05).Six patients experienced a decline in ovarian reserve function in both two groups(suture group: n=2;electrocoagulation group: n=4).Conclusion Different methods of hemostasis during laparoscopic ovarian cyst excision would cause different impacts on ovarian reserve function.The use of bipolar electrocoagulation could decline ovarian reserve function more obvious than the sutured group.
