Summary
Helicobacter pylori (HP) colonisation is high in patients with ulcers. Distal gastric resection significantly reduces HP presence, while selective proximal vagotomy shows little effect on HP status.
Area of Science:
- Gastroenterology
- Microbiology
- Surgical Oncology
Background:
- Helicobacter pylori (HP) is a significant factor in upper gastrointestinal diseases.
- Understanding HP prevalence post-ulcer surgery is crucial for patient management.
Purpose of the Study:
- To investigate the influence of surgical interventions on gastric mucosa colonization by HP.
- To assess HP prevalence in patients with and without upper gastrointestinal lesions.
Main Methods:
- Study included 387 patients undergoing upper gastrointestinal endoscopy.
- HP detection utilized microbiological examinations, histology, CLO-test, and 13C-urea-breath test (98% sensitivity).
- Compared HP status in patients with duodenal ulcers, gastric ulcers, and no lesions, as well as post-gastric resection and vagotomy.
Main Results:
- HP prevalence was 90% in duodenal ulcers, 70% in gastric ulcers, and 27% in controls.
- Distal gastric resection (removing antrum) resulted in rare HP detection (19%) near anastomosis.
- Selective proximal vagotomy for duodenal ulcers showed high HP prevalence (80%), similar to non-operated patients.
Conclusions:
- Distal gastric resection effectively reduces HP colonization by removing the antrum.
- Selective proximal vagotomy does not significantly alter HP colonization rates.
- Postoperative HP status varies significantly based on the type of ulcer surgery performed.
