Exclusion criteria
* Severe liver- or renal disease * Pregnancy or lactation * Planned diagnostics or treatment with radioactive iodine \< 1 week after surgery * BMI \>35 kg/m2 * Known or suspected hypersensitivity to indocyanine green, sodium iodide or iodine * Hyperthyroidism or thyroid adenomas * Use of medication interfering with ICG absorption as listed in the summary of product characteristics.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Peritoneal perfusion | 3 minutes after intravenous injection of indocyanine green | 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. |
