The Effect of CO Pressure and Flow Variation on Carbon Particles Spread During Pneumoperitoneum: An Experimental Study.

A correlation between atypical recurrences and minimally-invasive surgery has been suggested in case of urothelial cancer; however, few data are available on the role of pneumoperitoneum in terms of gas flow and intra-abdominal pressure. The objective of the study is to analyze the impact of CO pneumoperitoneum variation on an inert material as surrogate of neoplastic cells. We designed an experimental model mimicking pneumoperitoneum in three settings: sealed flow (no leakage), pulsatile flow (alternating efflux and influx), and continuous flow (AirSeal insufflator).
