Integrated application of modern endoscopic method selaborated in diagnosis of epithelial tumors of the colon

The purpose of the study - to evaluate the possibilities of contemporary visual differential diagnosis of early forms of malignant tumors and benign tumors of the colon in the present paper analyzes the results of a retrospective study of endoscopic 211 patients whose diagnosis is seamless. These patients was performed a comprehensive study in which 327 identified entities. Based on the results of histological examination of the biomaterial and visual evaluation, the patients divided into the following groups: Early colon cancer -34 education, focal hyperplasia of the mucous membrane - 45 formations, polyps (adenomas with dysplasia of varying degrees) - 193 education, limited infiltrative cancer - 43 education neuroendocrine tumor formations -7, non-epithelial tumors - 3 patients, colon -2 melanoma patient. Results: Visual and histological findings coincided in 90.6 %, sensitivity -94, 2 %, specificity 89.7%, positive predictive value, 90.4%, negative predictive value of 83.6 %, diagnostic accuracy of the method 90, 6% Conclusion: The use of complex endoscopic diagnosis can detect changes neoblast colonic mucosa in the early stages of development, as well as c accurately verify morphologically.
