Abstract

BACKGROUND/AIMS
We aimed to compare the outcomes and timing of Helicobacter pylori eradication in patients with iatrogenic and peptic ulcers. MATERIALS AND METHODS: This was a retrospective study of 183 patients treated between 2012 and 2015 with 7-day standard triple therapy after endoscopic resection (ER). The patients were enrolled as the iatrogenic ulcer group and assigned to an early treatment group (n=139, H. pylori eradication initiated 2 days after ER) and a late treatment group (n=44, 8 weeks after ER). During the same period, 152 patients with peptic ulcer were assigned to the peptic ulcer group. RESULTS: Successful H. pylori eradication was achieved in 141 patients (77.0%) in the iatrogenic ulcer group and 114 (75.0%) in the peptic ulcer group (P=0.661). Among the ER patients, the eradication rate was 79.9% (n=111) in the early treatment group and 68.2% (n=30) in the late treatment group (P=0.109). The adverse event rate was significantly higher in the peptic ulcer group than in the iatrogenic ulcer group (13.8% vs. 4.9%, P=0.005). Compliance and adverse events did not significantly differ between the early and late treatment groups. CONCLUSIONS: In iatrogenic ulcer, H. pylori eradication can be performed with a relatively lower adverse event rate, regardless of treatment timing, than that in peptic ulcer.
