Results of adhesion assay. A: 0 h after CO2 insufflation; B: 72 h after CO2 insufflation. At 0 h after CO2 insufflation (A), with increasing CO2-insufflation pressure, the adhesion of the SW1116 cell line decreased gradually (12 mmHg vs control, P < 0.001; 15 mmHg vs 12 mmHg, P < 0.001). At 72 h after CO2 insufflation (B), cell adhesion was similar among the different groups (P > 0.05).
