Abstract

Aims "Study on the relationship of age, endoscopic image with cancerous colorectal polyps according to the size of polyps". Research Patients and methods: A prospective, descriptive, cross-sectional study. Enroll 284 patients with 362 polyps including 13 cancerous polyps at Bach Mai Hospital, from 8/2020 to 8/2021. Results: The average age of patients with cancerous polyps was 64 (the youngest 32, the oldest 85 years old). In this study, polyp size < 10mm without cancerous polyps. Cancerous polyps mainly in the sigmoid colon and rectum: 46.2% and 38.5%. The average size of cancerous polyps is 24.38 ± 9.87mm (10mm minimum, 50mm maximum). The percentage of cancerous polyps according to size: 10-19mm 3.96%, 20-29mm 11.42%, and ≥ 30mm 25%. 92.3% cancerous polyps in patients ≥ 40 years old. Conclusions: Colorectal polyps are considered premalignant lesions, so colonoscopy to screen for cancer in people ≥ 40 years old, including those asymptomatic. Colorectal polyps should be removed, especially polyps ≥ 10mm.
