In this paper, we defined a linear ulcer as one located in parallel with the lesser curvature of the stomach, excluding another type of linear ulcer crossing the lesser curvature, and investigated this linear ulcer by the endoscopical follow-up study. Observing 386 cases of round ulcers of the stomach, endoscopically followed up more than 3 months, we classified them into four types of healing courses. Chronic longitudinal linear ulcer, that is, δ-course ulcer was located mainly on the corpus, and healed up easily and recurred most rarely among four courses. However, these characteristics were considered as the ones of ulcer on the corpus rather than the shape of ulcer. Furthermore, ten cases of acute longitudinal linear ulcer with 3 cases of Mallory-Weiss syndrome were investigated. Seven cases except Mallory-Weiss syndrome were located mainly on the fundic gland area, and showed the severe clinical symptoms (nausea, vomiting, hematoemtesis. etc.). They healed up faster than 8-course linear ulcer. On the site and shape, these acute ulcers might be differed from some previously reported cases of acute ulcer on the corpus of the stomach. For the future, we would like to investigate more cases of acute longitudainal linear ulcer, to clarify the pathophysiological features including the experimental procedures.
