RETROSPECTIVE ANALYSIS OF COLON POLYPS LOCALIZATION BASED ON THE RESULTS OF PATHOLOGOANATOMIC INVESTIGATIONS

The analysis of the conclusions of the results of pathoan-atomical researches of polyposis lesions of the colon in the department of pathological anatomy and forensic medicine of the LNMU named after Danylo Halytsky during the period of 2005-2016 was conducted. It was established that the most common localization of polyposis lesions was rectum and sigmoid colon. There is a significant (p <0.01) higher propor-tion of polyposis lesions in men than in women. In men, the rectum occupies the first place in the frequency of lesions, and the sigmoid colon in women. The overwhelming majority (3/4) of simultaneous lesions of two sections of the large intestine were observed in men. The most common lesions were associations with the sigmoid colon: sigmoid + ascending (32.14 ± 8.83% of all combinations), sigmoid + rectum (21.43 ± 7.75%), sigmoid + descending (14.29 ± 6.61 %). Aim. To study pathomorphological version of lo-calizations of polyposis lesions of the large intestine to estab-lish sexual distribution and morphological dominant lesions. Materials and methods. A retrospective analysis of the consultation conclusions of the pathologoanatomical researches with polyposis lesions of the colon of 760 patients, conducted at the Department of Pathological Anatomy and Forensic Medicine, Danylo Halytsky Lviv National Medical University in 2005 - 2016 years. For morphological study, fragments of polyps of the colon were used. Paraffin blocks were made from each fragment, histological staining with hematoxylin-eosin was performed. Results. In the study of morphological changes, the most widespread localization of the polyposis lesions of the colon and the distribution by sexual sing are established. Conclusions. 1. There is a significant (p <0.01) higher prevalence of polyposis lesions among men than women. 2. the most widespread localization of polyposis le-sions was direct and sigmoid colon. 3. The overwhelming majority (3/4) of simultaneous lesions of two sections of the large intestine were observed in men. The most common lesions were associations with the sigmoid colon: sigma + ascending (32.14 ± 8.83% of all combinations), sigma + rectum (21.43 ± 7.75%), sigma + descending (14.29 ± 6.61 %).
