Background

Helicobacter pylori• Gram-negative, curved S-shaped, microaerophilic

bacterium• Most common cause of gastritis, peptic and

duodenal ulcers and gastric adenocarcinoma

Objectives

• To find out the prevalence of H. pylori infection in chronic dyspeptic patients with peptic ulcer.

• To explore the relationship between the characteristics of ulcer and the H. pylori infection.

Method• A cross-sectional descriptive study was performed

by collecting data in EGD clinic, Naresuan University hospital during October 2004 to August 2012.

• The diagnosis of Helicobacter pylori infection was done by Rapid Urease Test and Histological examination.

• Stataversion12 was used to conclude the information.

Method

• Inclusion criteria– Patients with dyspepsia which had been

diagnosed by a specialist.– Patients who underwent upper gastrointestinal

endoscopy clinic at Naresuan University Hospital with indication of Dyspepsia.

– Patients with Helicobacter pylori infection results diagnosed by Rapid Urease Test and / or Histological Examination.

Method

• Exclusion criteria– Patients with other indications for upper

gastrointestinal endoscopy beyond dyspepsia.– Patients who were diagnosed as Helicobacter

pylori infection by both Rapid Urease Test and Histological Examination.

Conclusion

• The prevalence of H. pylori infection was still high in the chronic dyspeptic patients with peptic ulcer.

• This may relate to GU, DU and combined GU and DU.

• There was no significant difference in relationship between endoscopic findings and Helicobacter pylori infection which detected by Rapid urease test or Histological examination.
