It is very important to classify the stages of duodenal ulcer by using endoscopy in order to elucidate the life cycle, natural history or clinical course of this disease. Moreover, it is also necessary for evaluation of anti ulcer agents. Therefore, author tried to prepare the new classification of healing process of duodenal ulcer from the new points of findings of ulcer and adjacent mucous membrane by using front view type-panendoscope. In comparison with histology of operatively resected specimen duodenal ulcer was classified endoscopically as follows ; active stage, healing stage I, II, III, and IV, and scarring stage I and H Then, author applied clinically this new classification to the further observation of duodenal ulcer in each case, and concluded that this new classification was useful for observation of life cycle of duodenal ulcer. However, this may be tentative trial until generally accepted classification of duodenal ulcer is established.
