It is estimated that about 50% of people are infected with this bacterium in Taiwan. Many studies have shown that H. pylori is an important causal factor of chronic gastritis, peptic ulcer disease, gastric cancer and gastric lymphoma. The World Health Organization classified H. pylori as a Group 1 carcinogen in 1994. Endoscopic examination is indicated to confirm the above diagnosis for patient with H. pylori infection. Eradication of H. pylori infection reduces the risk of gastric cancer and recurrence of peptic ulcer disease. However, the eradication rate of clarithromycin-based triple therapy has been declining in recent years, probably related to the increasing resistant rate to clarithromycin. Several strategies have been proposed to overcome the declining eradication rate, including (1) extending the treatment duration of triple therapy to 14 days; (2) the use of bismuth quadruple therapy which contains bismuth, a proton pump inhibitor, and two antibiotics (usually metronidazole and tetracycline); (3) non-bismuth quadruple therapy (concomitant therapy) which contains a proton pump inhibitor and three antibiotics (usually amoxicillin, metronidazole, and clarithromycin); (4) sequential therapy which contains a proton pump inhibitor (PPI) plus amoxicillin for five days, followed by a PPI plus clarithromycin and tinidazole for another five days. The investigators aim to improve the eradication rate of H. pylori infection while an endoscopic examination is performed.', 'detailedDescription': 'During the endoscopic examination, patient is sedated with intravenous Dormicum 5mg (5mg/1ml/amp), the vital signs will be closely monitored by physiological monitor (PHILIPS SureSigns VM6). The treatment will be terminated immediately if unstable vital sign detected or if patient asks for termination. With endoscope apparatus, the gastric mucous is irrigated with acetylcysteine solution and the pH value of gastric juice will be measured with the pH test strips before irrigation and after irrigation. The investigators dispense medicaments containing three kinds of antibiotics powder (Amoxicillin 3 gm、Metronidazole 2 gm and Clarithromycin 1 gm) on the surface of gastric mucosa and duodenal mucosa of duodenal bulb as evenly as possible. After the intraluminal therapy, patients will rest for 30 to 60 minutes and go home if the effect of sedation subsided. Patients can take meal if no abdominal discomfort. Patients will receive tests for serum Helicobacter pylori immunoglobulin G, liver function and renal function 3 to 7 days after the intraluminal therapy. C13-Urea breath test (UBT) will be used to assess the existence of H. pylori 6 weeks after the intraluminal therapy. Stool H. pylori Antigen will be used to assess the short term recurrence of H. pylori 4-6 months after successful intraluminal therapy . Patients fail to achieve intraluminal eradication of H. pylori will be randomly assigned to the oral antibiotics rescue therapies with standard triple therapy for either 7 days (Group A) or 14 days (Group B). C13-UBT will be used to assess the existence of H. pylori 6 weeks after the rescue triple therapy. Overall eradication rates after the first line intraluminal therapy and the oral antibiotics rescue therapies will be evaluated.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '75 Years', 'minimumAge': '20 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
