Gastric mucosa changed to enhancement with whitening and could be observed in detail with magnifying endoscopy after acetic acid instillation. The aceto-whitening of gastric cancerous mucosa disappeared compared to surrounding non-cancerous mucosa and the contrast of cancerous and non-cancerous mucosa became clear. The duration of aceto-whitening differed according to each histological type : aceto-whitening of well differentiated adenocarcinoma disappeared in 10~20 minutes and moderately differentiated adenocarcinoma disappeared in a few minutes. Magnifying endoscopy was very useful for detection, diagnosis of histological type and determination of the extent of gastric adenocarcinoma in small gastric cancer about 1cm in size. Endoscopy with acetic acid was not chromoendoscopy because it did not use dye and it was possible to observe changes in the whitening with time. Acetic acid-enhanced magnifying endoscopy can therefore be termed “dynamic chemical magnifying endoscopy(DCME)”.
