The Effect of Salpingectomy on Ovarian Reserve Using Two Different Electrosurgical Instruments: Ultrasonic Shears...

Background Salpingectomy is a common surgical procedure in gynecology performed for various indications. Given its proximity to the ovaries and shared vascular supply, concerns have arisen regarding compromised ovarian reserve post-salpingectomy. Objective We aim to study the effect of two different energy sources (group 1: salpingectomy using bipolar electrocautery followed by division with scissors versus group 2: salpingectomy with ultrasonic shears) on residual ovarian reserve. The effect on ovarian reserve was assessed using serum levels of follicle-stimulating hormone (FSH), anti-Müllerian hormone (AMH), antral follicle count (AFC), and ovarian size pre- and postoperatively. Materials and methods According to the inclusion criteria, 68 women were included in the study and randomized into the bipolar electrocautery group and the ultrasonic shear group. The final analysis included 34 women in the bipolar electrocautery group and 32 in the ultrasonic shear group. Preoperatively, the ovarian reserve of all women was assessed using FSH, AMH, AFC, and ovarian size. These parameters were then reassessed at three months postoperatively, and the percentage change was analyzed. Results The mean baseline serum AMH and serum FSH values in the bipolar electrocautery group were 3.9 ± 2.9 ng/ml and 6.6 ± 2.1 IU/L, respectively, comparable with the values in the ultrasonic shear group, where serum AMH was 3.2 ± 2.9 ng/ml and serum FSH was 7.3 ± 3.9 IU/L. AFC and ovarian size were comparable between the two groups preoperatively (bipolar electrocautery group AFC was 8 ± 2.2, ovarian size on the right side was 3.3 ± 0.7 cm and on the left was 3.2 ± 0.6 cm; ultrasonic shear group AFC was 5.7 ± 2.3, ovarian size on the right side was 3.4 ± 0.8 cm and on the left was 3.2 ± 0.8 cm). After three months of postoperative analysis, AFC showed a significant fall from the preoperative value in the bipolar electrocautery group compared to the ultrasonic shear group (AFC reduced from 8 ± 2.2 to 5.5 ± 2.3 vs. 8.6 ± 0.5 to 7.9 ± 2.3; p=0.002). The other parameters showed no statistically significant change. Conclusion Our study suggests that ultrasonic shear is safer than bipolar electrocautery for preserving ovarian reserve after salpingectomy. However, further research is needed to confirm these findings.
