Helicobacter pylori (H. pylori) infection is the principal cause of chronic gastritis, gastric ulcers, duodenal and cancer. In clinical practice, diagnosis H. by a gastroenterologists' impression endoscopic images inaccurate cannot be used for management gastrointestinal diseases. The aim this study was to develop an artificial intelligence classification system pre-processing machine learning methods. Endoscopic body antrum from 302 patients receiving endoscopy with confirmation status...

Abstract Background Sequential therapy has been recommended in the M aastricht IV / F lorence C onsensus R eport as first‐line treatment for H elicobacter pylori eradication regions with high clarithromycin resistance. However, it fails 5–24% of infected subjects, and levofloxacin‐containing triple rescue only achieves a 77% rate after failure sequential therapy. Aim To investigate efficacy novel quadruple comprising proton‐pump inhibitor, bismuth, tetracycline, levofloxacin Methods This was...
