RELATIONSHIP BETWEEN ENDOSCOPIC FEATURES ACCORDING TO JNET AND HISTOLOGY OF COLECTAL POLYP SIZE ≥ 2CM
Main Article Content
Abstract
Objectives: Analyze the relationship between endoscopic features according to Japan NBI Expert Team (JNET) and histopathology of colorectal polyps ≥ 2 cm in size. Methods: This is a cross-sectional study, prospective, randomized design, performed on 88 patients with colorectal polyps ≥ 2 cm in size, from June 2023 to June 2024. Using the machine Olympus CV-190 endoscopy to evaluate polyps according to JNET classification. Results: Men accounted for 72.7%, higher than the rate of women. The age group > 60 had the highest rate of 52.3%. The rate of polyps in the sigmoid colon was the highest at 48.9%. The average size of polyps was 2.53 ± 0.78 cm. JNET 1 classification had a rate of 4.5%, JNET 2A had a rate of 61.4%, JNET 2B had a rate of 21.6%, JNET 3 had a rate of 12.5%. 100% of JNET 1 lesions were hyperplastic polyps, 100% of JNET 2A lesions were low and high grade dysplasia, 31.6% of JNET 2B lesions were cancers, 100% of JNET 3 were tubular and tubulovillous adenocarcinomas, these differences were statistically significant, p < 0.05. Conclusion: JNET classification has a significant relationship with histopathological classification of colorectal polyps; the higher the JNET grade, the more malignant the lesion.
