Abstract
Objective
This study aimed to evaluate the efficacy of unilateral laparoscopic ovarian drilling versus bilateral laparoscopic ovarian drilling with thermal dose adjusted according to ovarian volume in clomiphene citrate (CC)-resistant PCOS patients in terms of endocrine changes, menstrual cycle resumption, ovulation and pregnancy rates.
Patients and Methods
This study was conducted in the Department of Obstetrics and Gynecology, Zagazig university hospitals. One hundred CC-resistant PCOS patients were divided into two groups. Group (I) (50 patients) underwent unilateral laparoscopic ovarian drilling with thermal dose adjusted according to ovarian volume (60 J/cm3 of ovarian tissue), and group (II) (50 patients) underwent bilateral laparoscopic ovarian drilling using the same previously mentioned thermal dose. Endocrinal changes and menstrual cycle resumption were assessed within 8 weeks postoperatively, but the ovulation and pregnancy rates were estimated after 6-month follow-up period.
Results
There was no statistically significant difference between the two groups as regards demographic data (p > 0.05). As regards menstruation cycle resumption (62.5 vs. 81%) (p = 0.047), total ovulation rate (54.2 vs. 78.7%) (p = 0.011) and cumulative pregnancy rate (33.3 vs. 55.3%) (p = 0.031), there was statistically significant difference between both groups. After drilling, there were highly statistically significant decrease in the mean serum levels of luteinizing hormone (LH) and significant decrease in the mean serum levels of testosterone in both groups. Mean serum level of follicle stimulating hormone (FSH) did not change significantly in both groups after drilling.
Conclusion
Bilateral laparoscopic ovarian drilling with thermal dose adjusted according to ovarian volume is more effective than the right-sided unilateral technique with thermal dose adjusted according to ovarian volume in terms of menstrual cycle resumption, ovulation and cumulative pregnancy rates in CC-resistant PCOS patients.
