Design outcomes

Primary

Measure	Time frame
Intraoperative, intra-abdominal surgical smoke particle concentration (Particle number concentration (1/cm3)) as well as the intraoperative, intra-abdominal particle release rate (Particle release rate (1/sec.))	—

Secondary

Measure	Time frame
Stability of the capnoperitoneum, total CO2 consumption, assessment of the intraoperative vision by the three surgeons (Likert scale: 1-5), freedom during the operation (interference of smoke elimination with the operation; Likert scale 1-5), number of cleaning cycles of the camera by intraoperative smoke exposure, olfactory annoyance from smoke (Likert scale 1-5), other interferences of the operation with the technology used (e.g. trocar obstruction, interference with the ion wall, etc.) and the duration of the operation. Volume of the capnoperitoneum until reaching 15 mmHg (volumetric liters) for all patients	—
