Abstract
Peptic ulcer can occur anywhere in the gastrointestinal tract that contact with acid and pepsin. But usually peptic ulcer occurs at the stomach and duodenum and the location of peptic ulcer are localized to specific area within the stomach and duodenum. So I think that predilection of peptic ulcer to localized area may have clue for releaving the pathogenesis of peptic ulcer. So I studied the location of peptic ulcer for the basic reserch of ulcer pathogenesis by means of dividing stomach into antrum, angle, lower body, middle body, upper body and lesser curvature, anterior wall, greater curvature, posterior wall and duodenum into anterior wall, lesser curvature, posterior wall, and greater curvature. The results obtained were as follows: 1) The chronic gastric ulcer was most common in the angle of lesser curvature (22.9%) and second common in the antrum of lesser curvature (22.3%). 2) The location of chronic and acute gastric ulcer was similar. 3) The proximal migration of ulcer site according to increasing age was not observed. 4) Chronic duodenal ulcer was occurred commonly in the lesser curvature (41.8%) and anterior wall (38.3%). 5) As the age increase, the incidence of chronic duodenal ulcer in the lesser curvature was increased and that of chronic duodemal ulcer in the anterior wall was decreased. 6) Acute ulcer of stomach and duodenum has no predilection site.
