This study evaluates the effect of per-operative music on the bio-molecular inflammatory response in laparoscopic surgery. Per-operative music intervention will be given to the test group via headphones while the control group will be applied headphones without any music (Silent). The inflammatory stress response will be measured postoperatively at 6 hours and 24 hours postoperatively along with the baseline levels measured preoperatively. The values will be compared between the test and control groups.
