Small colorectal polyps as predecessors of colorectal cancer
Objective. Аnalysis of pathohistological structure of small polyps (up to 5 mm in size), revealed while doing colonoscopy, and estimation of their transformation into malignant tumors.
Маterials and methods. The work was performed on the base of Division of Endoscopy in Department of Surgery in Central Hospital of Customs, City of Baku. There were endoscopically excised, using the biopsy forceps, 42 small polyps, and estimated pathohistologically.
Results. Of 42 small polyps in 11 the signs of dysplasia were revealed, in 31 polyps the signs of dysplasia were absent. In accordance to pathohistological data the polyps were classified as hyperplastic - 11, inflammatory - 11, glandular - 19, glandular-villous - 1. Polyps, owing dysplasia signs, were referred to glandular and glandular-villous.
Conclusion. The investigation have confirmed, that in some observations a direct proportionality between a polyp size and his pathohistological structure was absent, and even in small polyps a dysplasia signs are revealed. Thus, small polyps may be considered as “cancerous predecessors”. Identification and excision of adenomatous polyps lowers the risk for colorectal carcinosis and malignancies occurrence on early stage.
