title: Ulcer recurrence after gastric surgery: is Helicobacter pylori the culprit?
abstract: OBJECTIVE
  Helicobacter pylori is the most important cause of recurrent peptic ulcer disease. However, its role in ulcer recurrence after peptic ulcer surgery is unclear. We aimed at studying the prevalence and distribution of H. pylori in patients who had undergone peptic ulcer surgery, and any association between H. pylori infection and ulcer recurrence in these patients.
  
  
  METHODS
  Patients with previous vagotomy or partial gastrectomy presenting with dyspepsia or ulcer bleeding were recruited. Ulcer recurrence was documented by endoscopy. Biopsy specimens were taken from the gastric remnant and gastroenteric anastomosis in patients with previous partial gastrectomy, or from the antrum and corpus in vagotomized patients. H. pylori infection was detected by either a positive rapid urease test or the presence of the bacteria on histology.
  
  
  RESULTS
  Ninety-three patients were studied; 73 patients (78%) had partial gastrectomy and 20 (22%) had vagotomy with drainage. H. pylori infection was documented in 36 patients (49%) in the gastrectomy group and in 13 (65%) in the vagotomy group. Thirty-six patients in the gastrectomy group had recurrent ulcers and 15 (42%) of them had H. pylori infection. Twelve patients in the vagotomy group had recurrent ulcers and eight (67%) of them were H. pylori positive. The prevalence of H. pylori infection did not differ between patients with or without ulcer recurrence.
  
  
  CONCLUSIONS
  H. pylori infection cannot account for ulcer recurrence after peptic ulcer surgery.
