Protocol summary

Summary
The purpose of this study was to compare the effect of two insufflation pressures on liver enzymes in patients who underwent laparoscopic cholecystectomy. Patients with acute chlocystitis scheduled for laparoscopic cholecystectomy were enrolled in the study. Exclusion criteria include need for changing from laparoscopic to open approach during surgery, need for increasing abdominal pressure in low pressure pneumoperitoneum group and gallbladder rupture during surgery. 130 patients were included in the study which were randomly assigned to two groups. In group 1 and group 2, 8 mmHg pressure pneumoperitoneum and 14 mmHg pressure pneumoperitoneum were used, respectively. The primary outcome measure was liver enzymes. The level of liver enzymes was measured preoperatively and 24 and 48 hours after surgery.
