Implementation of chromoendoscopy for inflammatory bowel disease surveillance did not increase dysplasia detection compared with white light endoscopy with targeted and random biopsies, according to a study published in the American Journal of Gastroenterology.
Researchers identified patients with ulcerative colitis and Crohn's disease undergoing colonoscopic surveillance between January 2000 and November 2013.
Researchers found that 440 colonoscopies in 401 patients were performed using chromoendoscopy and 1,802 colonoscopies in 772 patients were performed using WLE. Dysplasia was detected during 48 surveillance procedures in the chromoendoscopy group as compared with 189 procedures in the WLE group. Targeted biopsies showed 59 dysplastic lesions in the chromoendoscopy group, whereas 211 dysplastic lesions were detected in the WLE group using targeted biopsies.
