Abstract

Objective The objective of this study was to assess the clinical utility of ultrasound hemodynamic examination in predicting pregnancy outcomes following laparoscopic surgical intervention for ovarian endometriotic cysts. Methods A retrospective analysis was performed on clinical information collected from 95 patients with ovarian endometriotic cysts and who underwent laparoscopic surgical intervention. These patients were divided into a pregnant group (43 cases) and a non-pregnant group (52 cases) according to whether pregnancy was achieved within 24 months after surgery. Color Doppler ultrasound was utilized to assess ovarian blood flow indices, in all patients prior to the surgical intervention, and subsequently at the postoperative intervals of 1 and 3 months. Radioimmunoassay techniques were applied to quantify the concentrations of circulating reproductive hormones before the operation and at the follow-up time points of 1, 3, and 6 months. Results The overall pregnancy rate within 24 months after surgery was calculated as 45.26%. At the postoperative intervals of 3 and 6 months, the pregnant group demonstrated notably elevated serum E2 concentrations relative to the non-pregnant group ( P < 0.05). Conversely, the pregnant group exhibited substantially reduced FSH levels ( P < 0.05). Regarding ultrasound hemodynamic assessments, at the postoperative time points of 1 month and 3 months, the recorded RI, PI, and S/D values were observed to be substantially decreased in the pregnant group when contrasted with the non-pregnant group ( P < 0.05). A subsequent multivariate Logistic regression analysis identified that the postoperative ovarian ultrasound hemodynamic parameter RI served as an independent predictive factor for pregnancy prediction. Conclusion Ultrasound hemodynamic examination could effectively evaluate the ovarian blood perfusion status of patients with ovarian endometriotic cysts after laparoscopic surgery. Among the parameters, ovarian resistance index (RI) was confirmed as an important indicator for predicting postoperative pregnancy, which could provide a reference for optimizing clinical fertility guidance strategies.
