The Effect of Intra-abdominal Pressure on Peritoneal Perfusion During Laparoscopic Colorectal Surgery (PERFUSION)

May 7, 2020 updated by: Radboud University Medical Center

The Effect of Intra-abdominal Pressure on Peritoneal Perfusion During Laparoscopic Colorectal Surgery: a Pilot Study

Peritoneal perfusion during laparoscopic surgery is quantified by video recording after intravenous injection of indocyanine green at a pneumoperitoneum pressure of 8, 12 and 16 mmHg.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Peritoneal perfusion
Time Frame: 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.
