Results of Research on Identifying Patients with Colon Neoplasias with Gas Discharge Visualization Technique | Chapter 2 | Research Trends and Challenges in Medical Science Vol. 9

 The aim of this research was to see whether the Gas Discharge Visualization (GDV) technique could be used to identify patients with colon neoplasia.

Materials and Methods: A group of medical doctors evaluated subjects with various epithelial lesions using the Gas Discharge Visualization (GDV) camera. Each of the 132 participants had a colonoscopy followed by a GDV scan. In 77 patients, an endoscopic examination showed colon epithelial lesions. The remaining 55 people in the test group were free of lesions. The subjects ranged in age from 17 to 85 years old (mean 64.6 1.2). GDV images of each subject's finger were examined, with different sectors corresponding to the organs in question.

There were a number of important variations between the control group and the group of patients with colon tumours. We looked at how the parameters changed as the degree of tumour dysplasia (neoplasia) changed. As compared to patients with cancerous polyps, the values of the following parameters: normalised luminescence field, internal noise, contour radius, and average luminescence strength - decrease in the control group. By contrast, the values of the following parameters increased: radius of the inscribed circle, contour line length, luminescence field, contour line fractality, contour line entropy, and shape coefficients.

Conclusion: There was a statistical disparity between the GDV parameters of patients with colon tumours and the control group in this pilot study.
