Abstract To compare the influence of electric coagulation hemostasis and the suture hemostasis of patients who underwent laparoscopic ovarian maturation teratoma excision on their ovarian reserve. Methods: From May 2016 to May 2021, 80 patients who wanted laparoscopic excision of ovarian teratoma were selected and were randomly divided into two groups (40 cases in each group). The patients in group A were given intraoperative coagulation hemostasis, and the patients in group B were given intraoperative suture hemostasis. The operation time and the amount of intraoperative bleeding of the patients in the two groups were recorded. The levels of estradiol (E2), follicle stimulating hormone (FSH), luteinizing hormone (LH), and anti Mullerian hormone (AMH) of the patients on the third day of the last menstrual period before surgery, on the third day after operation, and on the third day of the menstrual cycle in 1 or 6 months after operation were detected. Before operation and postoperative 1 and 6 months, transvaginal ultrasound were used to record antral follicles count (AFC), ovarian volume, and psilateral ovarian stromal blood flow peak (PSV) value. Results: There were no significant differences in operative time and intraoperative blood loss of the patients between the two groups (P＞0.05). The levels of E2 and AMH of the patients in the two groups in 3 days, 1 and 6 months after operation were significant lower than those before operation, but which of the patients in group B were significant higher than those of the patients in group A. The level of FSH of the patients in the two groups after operation was significant higher than that before operation, but which of the patients in group B was significant lower than that of the patients in group A (all P＜0.05). The LH level of the patients in the two groups after operation was significant higher than that before operation (P＜0.05), but there was no significant difference in the LH level of the patients between the two groups (P＞0.05). In 1 or 6 months after operation, AFC of the patients by ultrasound in the two groups was significant lower than that before operation, but which of the patients in group B was significant higher than that of the patients in group A (all P＜0.05). The ovarian volume and PSV value by ultrasound of the patients in group B were significant higher than those before operation, but which of the patients in group A had decreased significantly. The ovarian volume and PSV value by ultrasound of the patients in group B were significant higher than those of the patients in group A (all P＜0.05). Conclusion: Compared with that of coagulation hemostasis, suture hemostasis during laparoscopic ovarian maturation teratoma excision can better protect the ovarian reserve and is help to the recovery after operation.
