CLINICAL CHARACTERISTICS, IMAGES OF VIRTUAL MAGNIFYING CHROMOENDOSCOPY WITH BLI MODE IN PATIENTS WITH COLORECTAL POLYPS AT CAN THO CENTRAL GENERAL HOSPITAL
Main Article Content
Abstract
Background: Colonoscopy is the best method for detecting and treating polyps, helping to reduce the incidence of colorectal cancer by 76-90%. Magnified colonoscopy with BLI staining is used for early detection of colorectal polyps. Objective: To describe clinical characteristics, the images of virtual magnifying chromoendoscopy with BLI of patients with colorectal polyps.
Materials and methods: This was a descriptive study on a total of 100 colorectal polyps of 70 patients at Can Tho Central General Hospital from March 2021 to June 2022. The patients underwent a colonoscopy to detect polyps. Then, polyps were magnified endoscopically stained using the BLI mode according to the JNET classification. Results: Patients with hematochezia accounted for 7.1% compared with no symptoms 37.1%. Location of polyps: Polyps were most common in the rectum (24%) and sigmoid colon (18%). According to the Paris classification, polyp type 0-IIa accounted for the highest 66%, of which 1 polyp type 0- IIa + IIc was recorded. JNET classification for magnified endoscopy with BLI staining, the rate of JNET polyps type 1, 2A, 2B, 3 was 60%, 36%, 3% and 1%, respectively. Conclusion: Colorectal polyps are usually asymptomatic. JNET type I polyps are the most common.
