Abstract

Background: An essential classification in applying Narrow Band Imaging (NBI) is the JNET classification, developed to predict the early histopathology and neoplastic features of colorectal polyps. Objectives: To describe the clinical characteristics of patients with colorectal polyps and the relationship between histopathological of colorectal polyps with the JNET classification. Materials and methods: A cross-sectional descriptive study was conducted on 90 patients who underwent colonoscopy at Can Tho University of Medicine and Pharmacy Hospital from 2023-2025. Results: The over 60 age group had the highest prevalence. The male ratio was higher in those under 60, while in those aged over 60 the gender distribution reversed with females making up 60%. The most frequent JNET classification was type I (43,3%). Polyps classified as type 2B and 3 had the highest rate of neoplasia. Polyps with high JNET classification types have a 3.7 fold higher risk of being neoplastic. Conclusions: The risk of developing polyps increases with age, and for colorectal polyps classified as higher types such as 2B and 3, the prediction of the histopathology is more accurate. The JNET classification helps predict the histopathology of colorectal polyps with a sensitivity of 75.7% and a specificity of 54.4%.
