The objective demonstration of improved postoperative recovery suggests that surgical injury induced by the laparoscopic approach is less intense than that after open surgery. Forty-two patients diagnosed as having noncomplicated gallstones were studied prospectively. They were operated on by laparoscopy (LC, n = 21) or open surgery (OC, n = 21). Both surgical procedures induced significant changes of investigated parameters (acute-phase response, free radical mediated reactions, neutrophil functions). Comparison of the results of the two cholecystectomy techniques showed that laparoscopic cholecystectomy induced a significantly less intense acute-phase response, a more attenuated oxidative stress characterising by free radical mediated reactions and that is less disruptive to neutrophil function. The results and the data from the literature suggest that surgical injury causing by the laparoscopic cholecystectomy is less intense than that after open cholecystectomy, which can explain partially the better clinical outcome following laparoscopic versus open procedure.
