Background: Although cold snare polypectomy (CSP) is considered effective in reducing delayed postpolypectomy bleeding risk, direct evidence supporting its safety the general population remains lacking. Objective: To clarify whether CSP would reduce risk after compared with hot (HSP) population. Design: Multicenter randomized controlled study. (ClinicalTrials.gov: NCT03373136) Setting: 6 sites Taiwan, July 2018 through 2020. Participants: Participants aged 40 years or older polyps of 4 to 10...

The efficacy of sequential therapy and the applicability genotypic resistance to guide selection antibiotics in third-line treatment Helicobacter pylori have not been reported. We aimed assess resistance-guided treatment. Genotypic phenotypic resistances were determined patients who failed at least two eradication therapies by PCR with direct sequencing agar dilution test, respectively. retreated containing esomeprazole amoxicillin for first 7 days, followed metronidazole plus...

<h3>Background and objective</h3> Whether there is distinct pathogenesis in subgroups of functional dyspepsia (FD), the postprandial distress syndrome (PDS) epigastric pain (EPS) remains controversial. We aimed to identify risk factors FD its Chinese population. <h3>Methods</h3> Patients with healthy subjects who underwent gastric cancer screening were enrolled this multicentre study from 2010 2012.

Objective The Taiwan Government issued a policy to restrict antimicrobial usage since 2001. We aimed assess the changes in antibiotic consumption and primary resistance of H. pylori after this impact virulence factors on resistance. Methods defined daily dose (DDD) antibiotics was analyzed using National Health Insurance (NHI) research database. strains isolated from treatment naïve (N=1395) failure prior eradication therapies (N=360) 9 hospitals between 2000 2012 were used for analysis....

INTRODUCTION: Concerns regarding bleeding remain in cold snare polypectomy (CSP) for small pedunculated (0-Ip) polyps. The aim of this study was to compare the risk CSP and hot (HSP) such lesions. METHODS: Data on 0-Ip colorectal polyps ≤10 mm were extracted from a large, pragmatic, randomized trial. Immediate postpolypectomy (IPPB), defined as perioperative use clip bleeding, evaluated through polyp-level analysis. Delayed (DPPB), occurring within 2 weeks postoperatively, assessed at...

The accuracy of genotypic resistance to levofloxacin (gyrA mutations) and its agreement with treatment outcomes after levofloxacin-based therapy have not been reported. We aimed assess the correlation. Helicobacter pylori strains isolated from patients who received clarithromycin-based triple therapies in a previous randomized trial were analyzed for point mutations gyrA 23S rRNA. PCR followed by direct sequencing was used rRNA mutations. An agar dilution test determine MICs clarithromycin...

Objectives: The efficacy of levofloxacin triple therapy has fallen below 80% in the second-line treatment ofHelicobacter pylori (H. pylori).We aimed to assess whether sequential is more effective than treatment. Methods: This open-label, randomized, multicenter trial was conducted between 2012 and 2015.H. pylori-infected subjects who failed from clarithromycin-based regimens (N=600) were randomized (1:1) receive (LS: lansoprazole amoxicillin for first 5 days, followed by lansoprazole,...

Abstract Background Probiotics may alter the gut microbiota and reduce antibiotic‐related dysbiosis after H . pylori eradication. However, whether probiotics are effective in reducing bacterial load of modifying remains unknown. We aimed to assess efficacy Lactobacillus acidophilus rhamnosus microbiota. Materials methods In this double‐blind, randomized, placebo‐controlled trial, we recruited 40 adult subjects with moderate high loads , defined as a mean delta over baseline (DOB) value 13...

Sequential therapy appears to achieve a higher Helicobacter pylori eradication rate than triple therapy. We assessed the efficacy and tolerability of modified sequential containing levofloxacin high-dose esomeprazole in second-line therapy.Patients who failed first-line with clarithromycin, amoxicillin proton pump inhibitor were eligible this multicentre trial. Eligible patients treated 40 mg 1 g for first 5 days, followed by mg, 250 metronidazole 500 another days (all given twice daily)....
