A case of duodenal ulcer and esophagitis at the different time after eradication of Helicobacter pylori (H. pylori) was experienced.
A 56-year-old male consulted our department at 40 years old because of epigastric pain. Endoscopic diagnosis was gastric ulcer at that time. H. pylori was detected by histological examination of endoscopic biopsy specimens in 1994. H. pylori eradication therapy was performed then. We recognized success of eradication and develop of duodenal ulcer 2 months later. Six months later, duodenal ulcer was healed by medication, but we found newly esophagitis. Eradication therapy of H. pylori decrease the recurrence rates of peptic ulcer, but has a possibility of onset of newly esophago-gastroduodenal lesions.
