Objective: To describe the endoscopic and histopathological characteristics of polypoid and non-polypoid colorectal lesions at the Luis Heysen Inchaustegui hospital, Peru, 2017-2018. Materials and methods: Descriptive-analytical cross-sectional study. We study epidemiological, endoscopic and histopathological variables. location, Size and shape of the lesions taking into account the Paris classification. Results: Endoscopically, of a total of 81 colorectal lesions, the majority were non-polypoid (71.6%). Lesions smaller than 10mm represented 90.1% in non-polypoid lesions and 56.5 % in polypoid lesions. Histopathologically, non-adenomatous lesions predominated (53.0%). Conclusions: The most frequent lesions were non-polypoid, the main location being the rectum; while in polypoid lesions, the transverse colon. Regarding size, lesions smaller than 10mm predominated in both non-polypoid and polypoid lesions. Histopathologically, the most frequent were non-adenomatous lesions (hyperplastic polyps); for its part, the predominant adenoma subtype was tubular.
