Background/Aims: Laparoscopy is advantageous but its adverse effects have not yet been completely elucidated. Pneumoperitoneum. performed to facilitate laparoscopy causes the organ perfusion decrease such as in the intestine. Oxidative stress reflects the tissue injury related to ischemia and reperfusion. We previously showed that laparoscopy causes oxidative stress in intestinal tissues. To assess whether the preconditioning phenomenon could be taken advantage of during laparoscopy we designed this randomized, controlled, experimental study with blind outcome assessment. We evaluated the effect of preconditioning, including sequential periods of pneumoperitoneum. and desufflation on laparoscopy-induced tissue injury of small bowel with the help of two important markers of oxidative stress, thiobarbituric acid reactive substances and reduced glutathione.
