The effects of three types of different hemostasis methods in laparoscopic cystectomy for ovarian endometriosis cyst on patients′ ovarian reserve function

Objective To explore the effects of three types of different hemostasis methods in laparoscopic cystectomy for ovarian endometriosis cyst on patients′ ovarian reserve function. Methods 122 patients with ovarian endometriosis cyst in our hospital from April 2011 to January 2012 were selected as research subjects.They received regular laparoscopic cystectomy for ovarian endometriosis cyst,and were allocated to an ultrasound knife group(31 patients),a bipolar electrocoagulation group(33 patients)and a suture group according to different hemostasis methods during the surgery.FSH and AFC level in patients upon admission,and in 1,3,6 and 12 months after the surgery were tested,and natural pregnancy of patients in 24 months after the surgery was observed.The effects of different hemostasis methods on ovarian reserve function between the three groups were compared. Results FSH level in the three groups upon admission was compared,with no statistical difference(P0.05).FSH level in 1,3,6 and 12 months after the surgery in the three groups all increased by difference extent,with statistical difference(P0.05).The levels in the suture group was significantly lower than that in the ultrasound knife group and bipolar electrocoagulation group respectively,with statistical difference(P0.05).AFC level in the three groups upon admission and in 1 month after the surgery was compared respectivly,with no statistical difference(P0.05).AFC level in the suture group in 3,6 and 12 months after the surgery was higher than that in the other two groups respectively,with statistical difference(P0.05).Natural pregnancy rate in the suture group was 36.2% in 24 months after the surgery,higher than that in the other two groups respectively,with statistical difference(F=7.285,P0.05). Conclusion Hemostasis methods of ultrasound knife and bipolar electrocoagulation which are applied in the laparoscopic cystectomy for ovarian endometriosis cyst both decrease patients′ ovarian reserve function and affect their natural pregnancy.In comparison,the effect of suture is relatively minor.
