[Erosive duodenitis after eradication therapy for Helicobacter pylori].
We studied the characteristics of erosive duodenitis after eradication therapy for Helicobacter pylori (Hp). Fifty-nine patients with Hp-positive peptic ulcer disease were treated with a combination of amoxicillin, clarithromycin, lansoprazol, and polaprezinc Subsequently, erosive duodenitis developed in 18 (43.2%) of 44 patients in whom Hp was eradicated successfully. There were no significant differences in demographic characteristics between the patients in whom duodenitis developed and those whom it did not, except that the incidence of duodenal ulcer before treatment was highte in the former group than in the latter. Erosions were located not only in the anterior wall of the first portion of the duodenum but also in the posterior wall or the second portion. Our results suggest that the development erosive duodenitis after Hp eradication therapy is a favorable, rather than an unfavorable, event, because erosive duodenitis appeared only in the patients with in whom Hp was successfully eradicated, moreover, the patients with duodenitis had no complaints and had a good prognosis without follow-up treatment.
