Objective:
The aim of this study was to investigate the feasibility of digital defog technique in 3D laparoscopic surgery for right colon cancer.
Methods:
Fifty patients with right colon cancer were divided into digital defogging group and control group. The intraoperative image clarity, the surgeon's anxiety, the time of operation and the time of fog nursing were compared.
Results:
The clarity of the video screen of the digital defogging group was significantly higher than that of the control group, and the degree of anxiety was significantly lower than that of the control group. The operative time was (136.4 ± 30.4) min in the digital defogging group, the operation time of the control group was (168.7 ± 32.7) min, and the difference was statistically significant (P < 0.05). The time of dehumidification was (4.8 ± 1.3) min in the digital defogging group and (16.3 ± 4.6) min in the control group, and the difference was statistically significant (P < 0.05).
Conclusion:
Digital defogging technology in the 3D laparoscopic right colon cancer surgery significantly improves the clarity of video images, reduces the surgeon due to screen clarity caused by anxiety, reduces the operation of right colon cancer time and reduces the time to fog care.
