| Abstract: | ObjectiveTo compare the efficacy of non-invasive testing for Helicobacter pylori with that of endoscopy (plus H pylori testing) in the management of patients referred for endoscopic investigation of upper gastrointestinal symptoms.DesignRandomised controlled trial with follow up at 12 months.SettingHospital gastroenterology unit.Participants708 patients aged under 55 referred for endoscopic investigation of dyspepsia, randomised to non-invasive breath test for H pylori or endoscopy plus H pylori testing.ResultsIn 586 patients followed up at 12 months the mean change in dyspepsia score was 4.8 in the non-invasive H pylori test group and 4.6 in the endoscopy group (95% confidence interval for difference –0.7 to 0.5, P=0.69). Only 8.2% of patients followed up who were randomised to breath test alone were referred for subsequent endoscopy. The use of non-endoscopic resources was similar in the two groups. Reassurance value, concern about missed pathology, overall patient satisfaction, and quality of life were similar in the two groups. The patients found the non-invasive breath test procedure less uncomfortable and distressing than endoscopy with or without sedation. No potentially serious pathology requiring treatment other than eradication of H pylori was missed.ConclusionIn this patient group, non-invasive testing for H pylori is as effective and safe as endoscopy and less uncomfortable and distressing for the patient. Non-invasive H pylori testing should be the preferred mode of investigation. What is already known on this topicEndoscopy is a commonly used investigation for upper gastrointestinal symptoms, but its effectiveness has been questionedNon-invasive testing for Helicobacter pylori has been shown to predict endoscopic diagnosis in patients with dyspepsiaWhat this study addsIn patients less than 55 years of age with uncomplicated dyspepsia, non-invasive testing for H pylori is as effective and as safe as endoscopyNon-invasive H pylori testing is as reassuring to the patient as endoscopy and is less uncomfortable and distressing |
