Endoscopic studies of 440 active duodenal ulcer patients (male 405, female 35) were carried out by using duodenofiberscope (Type JF-B). Multiple duodenal ulcer (58.9%) was found more frequently than single ulcer (40.7%), and two rare cases of duodenal retrobulbal ulcer were also ob served. The location of single ulcer in 179 cases was hold more frequently in the anterior wall of duodenal bold, and in order of lesser curvature, posterior wall and greater curvature. Multiple ulcer was mainly found in the anterior wall, and relieved the order of lesser curvature to posterior wall compared with single ulcer. Single ulcer assumed most frequently the form of linear ulcer, and multiple ulcer was mainly round form. Salami ulcer was observed in 109 cases (17.1%). Most of them was accompanied with duodenal open ulcer or ulcer scar, and it was discussed that the histological findings of salami ulcer was considered to be the erosive changes associated with duodenal ulcer. In this report, linear ulcer was more frequent compared with another authors. It might be related that the healing of linear ulcer was detected by dye-scattering method. The healing time of linear ulcer prolonged than another forms of duodenal ulcer, and the recurrence was occasionally noted. Peptic ulcer was sometimes coexisted in the sto-mach and duodenum (9.1%), gastric ulcer was found most frequently as the form of round ulcer in the gastric angle, and dundenal ulcer was round or linear form in the anterior wall. The healing time of duodenal single ulcer was not differed from multiple ulcer by means of the endoscopic observation. Many of duodenal ulcer patients with severe initial symptoms or with linear ulcer showed prolonged healing period. Anticholinergic drugs used alone paraenterally was not so much effective to heal duodenal ulcer within 3 months observation period, and the use of antacid or another antiulcerative drugs with anticholinergica was more effective.
