Prevalence and clinical importance of Helicobacter pylori infection in patients after partial gastric resection for peptic ulcer disease. A prospective evaluation of Helicobacter pylori infection on 50 resected patients compared with matched nonresected controls.

Unlabelled: There have been only a few surveys on the prevalence of persistent Helicobacter pylori (Hp) infection in patients who have undergone surgery for peptic ulceration. The aim of the study was to evaluate the prevalence and clinical importance of Hp infection after partial gastric surgery due to peptic ulcer disease.
Methods: We examined 50 patients who had partial gastric resection for peptic ulcer disease and years later underwent upper gastrointestinal (GI) endoscopy. 50 controls matched with respect to indication for GI endoscopy, age and gender were also studied. Three specimens from the fundus of gastric remnant were examined for Hp infection (histology and rapid urease test). The prevalence of Hp infection and pathology findings were compared between the two groups using chi-square statistics.
Results: 32 men and 18 women were examined (40 x BII, 10 x BI). The prevalence of Hp infection was 38% in the resected group compared to 60% in the control group (p = 0.015). We found a significant association (p = 0.0004) between Hp infection and endoscopic findings in the control group but not in the group of partially resected patients (p = 0.66).
Conclusion: The prevalence of Hp infection in hospitalized patients with partial gastric resection is significantly lower than in matched controls. Hp infection does not play a significant pathogenic role in recurrent ulcer after partial gastric resection in these patients.
