| Peritoneal perfusion | Perfusion is quantified by video recording of the parietal peritoneum using the Firefly fluorescence module of the DaVinci surgical robot after intravenous injection of 0.2mg/kg indocyanine green. Fluorescent intensity in [-] over time is plotted in MATLAB, maximum fluorescent intensity and time to reach maximum fluorescent intensity are extracted. | 3 minutes after intravenous injection of indocyanine green |
