Abstract
The mucosal pattern using enhanced-magnification endoscopy with 1.5% acetic acid in the distal esophagus and esophagogastric junction was classified into 3 types : I, normal pits; II, slit-reticular pattern; and III, gyrus-villous pattern. The presence of type I, type II, type III surface patterns was characteristic of, respectively, fundic epithelium, cardiac epithelium, and intestinal metaplasia. Additionally, type IV (irregular pattern) and type V (destructive or nonstructural pattern) are associated with Barrett's carcinoma and gastric carcinoma. Because some cases showed acetowhite reaction in surrounding mucosa of early gastric cancinoma conventional endoscopy after instillation of 1.5% acetic acid may be useful to detecting the margin of early gastric cancinoma.
