Brief Summary:
Helicobacter pylori H pylori is the most common chronic bacterial infection in humans
The prevalence of H pylori is about 3050 in the Western adult population 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 evaluate the efficacy of Amoxicillin powder in the Intraluminal therapy for Helicobacter pylori infection while an endoscopic examination is performed

Detailed Description:
During the endoscopic examination patient is sedated with intravenous Dormicum 5mg 5mg1mlamp 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 Patients will receive test for UFT300 to evaluate H pylori colonization in the gastric cardia 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 Amoxicillin powder in the capsule 3 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 C13-Urea breath test UBT will be used to assess the existence of H pylori 6 weeks after the intraluminal therapy Patients fail to achieve intraluminal eradication of H pylori will be assigned to the oral antibiotic rescue therapies with High-dose PPI-amoxicillin dual therapy rabeprazole 20 mg and amoxicillin 750 mg 4 timesday for 14 days C13-UBT will be used to assess the existence of H pylori 6 weeks after the rescue therapy Overall eradication rates after the first line intraluminal therapy and the oral antibiotics rescue therapies will be evaluated
