[Morphostatistical characteristics of adenomas of the large intestine based on the data from 1915 autopsies].

Large intestine polyps have been revealed in 1372 cases of 1915 autopsies. 4.1% of these have been hyperplastic polyps, 86.2% tubular adenomas, 11.1% tubular-villous and 2.7% villous adenomas. Solitary adenomas have been less frequent than multiple one (42 vs. 58%). The adenomas have been equally incident in the right and left portions of the large intestine, but they have been larger and characterized by a higher degree of epithelial dysplasia in the sigmoid and rectum. Malignant adenomas made up 0.8% of the total number of tumors. Adenomas have been revealed twice more frequently in the patients who died in hospital than in the group of forensic medical autopsies. Multifactorial analysis has demonstrated a correlation between adenoma detection rate and some chronic diseases.
