Abstract:
Objective To investigate the influence of CO2-insufflation pressure on invasion potential of the colon cancer cells.Methods With an in vitro artificial pneumoperitoneum model,SW1116 human colon cancer cells were exposed to CO2-insufflation of 5 different pressure groups:6,9,12,15 mm Hg and control group,respectively for 1 h.The invasion capacities of SW1116 cells exposed to CO2-insufflation of 5 different pressure groups were detected by cell adhesion/invasion assay in vitro.Results Immediately following exposure to 15 mm Hg CO2 insufflation,the invasion of SW1116 cells decreased significantly compared to the cells before exposure.At the 0 h time point,the cells exposed to 15 mm Hg were significantly less invasive than those exposed to the other insufflation pressure(P
