MAGNIFICATION ENDOSCOPIC VIEW OF AN EARLY GASTRIC CANCER USING ACETIC ACID AND NARROW-BAND IMAGING SYSTEM

A 62-year-old woman was referred to Mie University Hospital, Tsu, Japan, for examination of upper gastrointestinal tract. The conventional endoscopy showed a slightly depressed lesion on the greater curvature at the gastric body. The surface of surrounding non-neoplastic mucosa using magnification endoscopy with acetic acid was gyrus-villous pattern whereas the surface of the lesion was rough. Furthermore, magnification endoscopy using acetic acid and narrow-band imaging system visualized clearer fine surface pattern of carcinoma. The lesion had a rough mucosa with irregularly arranged small pits. The lesion was resected completely by endoscopic mucosal resection with insulated-tip electrosurgical knife. Narrow-band imaging system with acetic acid may be able to visualize not only the capillary pattern but also the fine surface pattern of gastric carcinoma.
