The study investigates the effects of induced pneumoperitoneum during surgery on ventilatory parameters including peak inspiratory pressure, lung compliance, end-tidal CO2 at specific time-points: after induction of anaesthesia, after induction of surgery, one-hour and two-hours during surgery, end of surgery. The effects of pneumoperitoneum are compared between two groups of patients: patients undergoing laparoscopic surgery and patients undergoing robotic-assisted surgery. No intervention was performed in this study and the decision for type of surgery performed was made by the attending surgeon prior to study inclusion

lung compliance
change in lung compliance (mL/cmH2O) before and after induction of pneumoperitoneum in patients undergoing VAS. Lung compliance is automatically calculated by the anesthesia machine during surgery. The study compares the magnitude in change associated with VAS.
Time frame: one-hour and two-hours after induction of pneumoperitoneum
arterial to end-tidal CO2 difference
difference in arterial to end-tidal CO2 (mmHg) during surgery. Arterial blood samples and end-tidal CO2 were simultanously obtained at the specific time-points.
Time frame: one-hour and two-hours after induction of pneumoperitoneum
