Six-year follow-up after Helicobacter pylori eradication in peptic ulcer disease.

摘要

BACKGROUND: The longterm outlook after Helicobacter pylori (H. pylori) eradication in peptic ulcer disease is unclear. AIM: This study documents H. pylori recurrence, dyspeptic symptoms and anti-secretory therapy in peptic ulcer patients six years or more after H. pylori eradication. METHODS: Peptic ulcer patients with H. pylori eradication between 1990 and 1992 were included. Infection recurrence was diagnosed by 13-carbon urea breath test (UBT). Dyspeptic symptoms and anti-secretory therapy use were assessed by questionnaire. RESULTS: Sixty-one patients completed the study protocol. Mean follow-up after eradication was 6.1 years (range 4.8-8.3). Four patients had a positive UBT. H. pylori recurrence rate was 6.6% or 0.02% per patient per year. Forty-two patients (69%) had dyspeptic symptoms. Heartburn and belching were more common than pain (p<0.001). All four patients with H. pylori recurrence had symptoms compared with 38 of 57 H. pylori-negative patients (p>0.05). Ten of 61 patients (16.4%) were taking anti-secretory therapy and their dyspepsia scores were higher. CONCLUSIONS: Despite a low H. pylori recurrence rate, longterm dyspeptic symptoms were common in peptic ulcer patients after H. pylori eradication. The symptoms are mainly reflux in type and require anti-secretory therapy in only a minority of patients.
