Purpose
To compare the ovarian reserve of different hemostatic methods after laparoscopic endometrioma stripping (LES) and explore which factors may affect ovarian reserve.
Methods
Patients who underwent LES from January 2019 to December 2021 were retrospectively included. Anti-Müllerian hormone (AMH) levels were measured before, and 3 months after surgery to determine changes of serum AMH in each patient. A multivariate linear regression analysis was performed to identify significant factors that were associated with the rate of decline of serum AMH levels at month 3 after surgery.
Results
A total of 67 patients who underwent LES were included. Of these patients, 20 with gauze packing, 24 with bipolar dessication (BD), and 23 with suture to achieve hemostasis. The 3 groups were similar in terms of demographics, cyst diameter, and basal AMH levels, except basal hemoglobin levels. At 3 months after surgery, the decline rate of AMH levels was significantly greater in the suture and BD group compared with the gauze packing group [48.2% (interquartile range, IQR, 28.1–67.1) and 31.1% (IQR,14.6–49.1) vs. 15.1% (IQR,1.1–24.5), P = 0.001]. On multivariate regression models, significant predictors of the decline rate of serum AMH levels at 3 months after surgery were hemostatic methods (p < 0.001), basal AMH levels (p = 0.033), and lesion bilaterality (p = 0.017).
Conclusion
Compared to BD or suturing hemostasis, gauze packing hemostasis led to less damage on ovarian reserve at 3 months after LES. Besides, hemostatic methods, bilateral endometriomas and basal ovarian reserve were independently correlated with the impairment of ovarian reserve after surgery.
