[Lipid peroxidation and antiradical defense in patients after endosurgical cholelithiasis].

The peroxide status was studied after cholecystectomy depending on the procedure of a surgical access and the duration of exposure to the pneumoperitoneum during laparoscopic operations. Endosurgical interventions, unlike open operations and miniaccess operations, were found to have the least impact on the values of lipid peroxidation (LPO) expirate. There was evidence that a marked imbalance occurred in the LPO-antioxidant system with longer exposure to the peritoneum.
