Abstract: Objective To investigate the effect of three kinds of hemostatic methods of electrocoagulation,suturing and oppression on the ovarian function after laparoscopic ovarian endometriosis cysts. Methods Two hundred and ten cases patients of laparoscopic ovarian endometriosis cystectomy in the First People's Hospital of Jiande City from January,2011 to December,2016 were selected,and were divided into compression group(pressure to stop bleeding),suture group(suture hemostasis) and electrocoagulation group(coagulation hemostasis).The levels of E2,T,FSH,LH and the number of follicles were measured before and after surgery at menstrual cycle 2-4 days.The levels of P was measured before surgery,1 month after surgery and 6 months after surgery at menstrual cycle 21 days. Results In compression group and suture group,the level of E2 at postoperative 1 month was lower than that in preoperative and postoperative 6 months(P<0.05),the FSH and LH levels were higher than those preoperative and 6 months after operation(P<0.05),there was no significant difference in E2,FSH and LH between the two groups at 6 months after operation(P>0.05).In electrocoagulation group,the levels of E2 at 1 month and 6 months after operation were lower than those before operation(P<0.05),the FSH and LH levels at 1 month and 6 months after operation were higher than those before operation(P<0.05),the level of E2 at 6 months after operation was lower than that before operation(P<0.05),the FSH and LH levels at 6 months after operation were higher than those before operation(P<0.05).The premature ovarian failure rate of electrocoagulation group was higher than that of compression group(P<0.05).In compression group and control group,the number of follicles at 1 months after operation was less than that before operation(P<0.05),there was no significant difference in the number of follicles between 1 months after operation and 6 months after operation(P>0.05),and was higher than 1 month after operation(P<0.05).In electrocoagulation group,the number of follicles after 1 month and 6 months after operation were lower than that before operation(P<0.05),the number of follicles at 6 months after operation was higher than 1 months after operation(P<0.05).At 1 month after surgery and 6 months after surgery,the number of follicles in electrocoagulation group was lower than that in compression group and suture group(P<0.05). Conclusion In laparoscopic ovarian endometriosis,the effect of press to stop bleeding on ovarian function is the least,the suture hemostasis on ovarian function is quite to oppression hemostasis,the electrocoagulation hemostasis has the greatest impact on ovarian function.
