USEFULLNESS OF NARROW BAND IMAGING (NBI) SYSTEM WITH MAGNIFICATION IN DIAGNOSIS AND TREATMENT OF COLORECTAL ADENOMA IN PATIENTS WITH CRONKHITE-CANADA SINDROME : A CASE REPORT

Abstract

A 62-year-old man with turbid nail, and skin hyperpigmentation was referred for diarrhea, and a positive fecal occult blood test. This patient had received upper GI and colonoscopy which revealed gastric and colorectal polyposis. We, therefore, diagnosed this case as Cronkhite-Canada syndrome (CCS). NBI can clearly visualize the microvascular structure of colorectal tumors and has been reported to be a useful and simple method for differentiating between colorectal neoplastic and non-neoplastic polyps without chromoendoscopy. So we observed multiple colorectal polyps in this CCS patient using NBI colonoscopy with magnification. Use of NBI identified the difference of colorectal adenomas from related inflammatory hyperplastic polyps with CCS. Consequently, we could perform an endoscopic mucosal resection efficiently and appropriately.
