ENDOSCOPIC IMAGING AND HISTOPATHOLOGICAL CHARACTERISTICS OF LARGE COLORECTAL POLYPS
Main Article Content
Abstract
Objectives: To describe the endoscopic imaging and histopathological characteristics of large colorectal polyps and the relationship between histopathology and some factors. Materials and methods: Cross-sectional study on 30 patients with colorectal polyps ≥ 20 mm, treated at Military Hospital 175, from January 2022 until December 2023. The histopathological diagnosis of colorectal polyps was based on the standards of the World Health Organization in 2019. Results: The average age of patients was 59.47 ± 10.52, the male/female ratio was 2.75/1. Polyps were mainly distributed in the sigmoid colon (46.7%) and rectum (30%), respectively. The sessile polyps accounted for 40%. The adenocarcinoma and tubulovillous adenoma polyp rates were 20% and 20%. The rate of sessile polyps in the colorectal adenocarcinoma group was higher than that in the neoplastic polyp group, the difference was statistically significant (p < 0.05). There was no relationship between age, gender, surface characteristics on endoscopy and the histopathology of large colorectal polyps. Conclusion: The adenocarcinoma rate of large colorectal polyps was 20%. The rate of sessile polyps in the colorectal adenocarcinoma group was higher than in the neoplastic polyp group, the difference was statistically significant (with p < 0.05
