ABSTRACT
Objective:To discusse the value of pituitin in laparoscopic ovarian cyst removal.Methods:From October 2015 to June 2018 in Dalian Medical University Affiliated Dalian Maternity Hospital, useing prospective research methods, 90 patients with unilateral ovarian cyst (except endometriomas) were randomly divided in 3 groups of pituitrin group,control group 1 and control group 2. The pituitrin group: laparoscopic cystectomy with the injection of diluted pituitrin 6 U, the total amount of diluted pituitrin 10 - 20 ml, ovarian hemostasis was achieved by sutura. The control group 1: ordinary laparoscopic cystectomy without injection suture hemostasis. The control group 2: laparoscopic cystectomy with the injection of normal saline 10 - 20 ml, ovarian hemostasis was same to pituitrin group. The operation time and the amount of bleeding were compared among the three groups. The ovarian reserve was compared between before and 3 months after operation by estradiol (E 2), follicle-stimulating hormone (FSH), luteinizing hormone (LH). Results:The amount of bleeding in the pituitrin group was less than that in the control group1: (14.00 ± 5.48) ml vs. (18.33 ± 6.99) ml, P<0.05. The operation time in the pituitrin group and control group 2 was less than that in the control group1: (43.50 ± 7.21) min, (45.00 ± 10.29) min vs. (50.17 ± 8.95) min, P<0.05. The level of FSH after operatiaon in the pituitrin group and control group 2 was less than that in the control group1: (7.20 ± 1.55) U/L, (7.43 ± 1.52) U/L vs. (8.31 ± 0.97) U/L, P<0.05. The level of E 2 3 months after operation in the pituitrin group was higher than that in the control group 1 and control group 2: (54.20 ± 10.90) ng/L vs. (46.63 ± 10.76) ng/L, (43.90 ± 18.23) ng/L, P<0.05. There was no significant difference of LH 3 months after operation among the three groups ( P>0.05). Conclusions:This study shows that diluted pituitrin decreases operation time and the amount of bleeding during operation, at the same time,the pituitrin injection is valued of ovarian reserve.
