Brief Summary

After endoscopic resection (ER) of gastric tumors, eradication of Helicobacter pylori (H. pylori) infection is advised to reduce metachronous recurrence. However, few studies have addressed factors influencing H. pylori eradication rates in the aftermath of ER, and none have focused on the optimal timing of therapy to eradicate H. pylori post-ER.Therefore, the investigators will conduct to evaluate whether differences in timing of eradication therapy after ER of gastric tumors.

Conditions

Outcome Measures

Primary Outcomes (1)

  • H. pylori eradication rate according to timing of therapeutic regimen after endoscopic resection

    The success of H. pylori eradication was determined using a urea breath test conducted

    The success of H. pylori eradication was determined using a urea breath test conducted 13 weeks ± 5 days after ESD

Study Arms (2)

early eradication group

In the post-endoscopic resection period, patients were grouped by timing (i.e., initiation) of therapy to eradicate H. pylori as follows: 1) early (≤ 2 weeks), 2) late (≥ 8weeks).

Other: eradication timing

late eradication group

In the post-endoscopic resection period, patients were grouped by timing (i.e., initiation) of therapy to eradicate H. pylori as follows: 1) early (≤ 2 weeks), 2) late (≥ 8weeks).

Other: eradication timing

Interventions

patients who underwent ESD for gastric neoplasms were randomized to receive early (3-5 days) or late (8-9 weeks) H. pylori eradication therapy after ESD.

Eligibility Criteria

Age20 Years - 90 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Patients who received proton-pump inhibitor (PPI)-based triple therapy for H. pylori eradication after endoscopic resection for gastric neoplasms. Clinicopathologic characteristics, particularly the timing of triple therapy, were used to compare eradication rates, assigning patients to early- (≤2 weeks),and late-phase (≥8 weeks) eradication groups.

You may qualify if:

  • patients underwent endoscopic resection of gastric neoplasm
  • patients who diagnosed as H. pylori infection by rapid urease test

You may not qualify if:

  • Histories of gastric surgery
  • Histories of prior H. pylori eradication therapy
  • Use of drugs affecting H. pylori positivity (proton pump inhibitor, histamine-2 receptor blocker, or antibiotics) within the preceding 2 weeks
