Background: The aim of this study was to evaluate ovarian damage following laparoscopic endometrioma cystectomy using ultrasound and pathologic samples.
Materials and Methods: This is a prospective cohort study in General Women Hospital affiliated to Tehran University of Medical Sciences. 40 patients with endometrioma, total of 44 cysts including bilateral cysts, underwent laparoscopic cystectomy with stripping technique. Amount of excised parenchyma, number of lost oocytes and cyst wall fibrosis thickness were histologically studied. Before and 3 months after surgery antral follicle count was evaluated by ultrasound.
Results: Mean antral follicle count (AFC) before the operation was 4 ± 1.29 and after operation was1.64 ± 1.03. The reduction in AFC after cystectomy was statistically significant (P <0.000), and with each 1 centimeter increase in cyst diameter a reduction of AFC averaging 0.421 was observed. On pathological examination, it was shown that every millimeter of inadvertently excised ovarian tissue and cyst wall fibrosis thickness leads to reduction of 1.06 and 1.2 in AFC respectively.
Conclusion: Laparoscopic cystectomy for endometrioma is associated with reduction in ovarian reserve and this reduces proportionally with cyst diameter, amount of normal ovarian parenchyma excised and cyst wall fibrosis.
