[Fiber colonoscopic and histomorphological characteristics of true polyps of the large intestine].

By fibrocolonoscopy, fibrocolonoscopic biopsy, polypectomy, operation resp., one hundred and eight true polypi in the colon of 75 patients were studied, grouped according to localization: in caecum -- 2.8 per cent, in ascending colon -- II. I per cent, transverse colon -- 13.9 per cent, descending colon -- 19.4 per cent, in sigmoid colon -- 40.8 per cent and in rectum -- 12 per cent. Endoscopically they were grouped as follows: adenomatous -- 91.7 per cent and villous -- 8.3 per cent and after the pathohistological examination as: adenomatous 73.3 per cent, adenovillous -- 17.2 per cent and villous -- 9.5 per cent. In 40 (52.8%) of the cases, well differentiated polypi were concerned (I grade); in 30 (38%) -- moderately differentiated polypi (II grade) and in 5 (6.5%) -- poorly differentiated polypi (III grade). The studies revealed that the pathohistological examination was a method, specifying the morphological structure of polypus, determining the therapeutic behaviour of the clinicists. Fibrocolonoscopic polyrectomy solves the problem of diagnostics and treatment of the true polypi, contributing to the prophylaxis of colon carcinoma.
