ABSTRACT
The aim of the study was to follow the impact of cystectomy and compare bipolar and laser electrocoagulation on prooxidative stress biomarkers and antioxidative capacity. A total of 60 women with diagnosed endometriosis were included in the study and divided in two groups according to laparoscopy treatment with different energy sources for electrocoagulation. Prooxidative parameters (superoxide anion radical (O2-), nitrites (NO2-), hydrogen peroxide (H2O2), index of lipid peroxidation measured as thiobarbituric acid reactive substances) and antioxidative defence system parameters (reduced glutathione (GSH), activity of superoxide dismutase (SOD), and activity of catalase (CAT)) were determined spectrophotometrically before and after the surgery. The value of H2O2 was decreased in group treated with biporal electrocoagulation, while the value of GSH was increased in both groups. The value of O2- was significantly decreased in the group treated with laser, while SOD activity was increased in the same group. Both methods had a similar effect on index of lipid peroxidase and reduced glutathione, but when it comes to the decreasing of harmful superoxide anion radical and increasing of SOD activity, laser electrocoagulation showed better outcome. The role of oxidative stress in both understanding the pathogenesis of this disease and as a potential therapeutic target is certainly of great importance.
