Suppressive conditions such as the intake of proton-pump inhibitors (PPIs), preceded antibiotic treatment or recent upper gastrointestinal bleeding impair H. pylori test quality. The aim of our study was to evaluate the frequency and pattern of H. pylori suppressive conditions in a large patient collective undergoing elective EGD in a German university hospital. Methods: The trial was performed as a single-center study. Only elective EGD from inpatients and outpatients were included. Prior to endoscopy, H. pylori suppressive conditions were collected using a standardized questionnaire. If H. pylori testing was indicated according to the guidelines, always both histology and helicobacter urease test were performed in analogy to the Sydney classification. Results: One thousand six hundred and thirty-one patients were included (median 61 years, 36.0% outpatients, 64.0% inpatients). Overall, 76.5% of patients were under H. pylori suppressive conditions. The main suppressive condition was the intake of PPIs (70.7%). In 819 (50.2%) of all included cases, H. pylori testing was performed. The following were the results: 17.3% (142) had a positive H. pylori testing and 82.7% (677) were negative. Of those with negative result, 70.0% were tested under suppressive conditions. Conclusion: Guidelines recommend H. pylori testing under non-suppressive conditions. However, this does not always meet the clinical practice. Our data show that de facto, many patients undergoing elective EGD are tested for H. pylori under suppressive conditions coming along with a higher risk of potentially false negative results. Particularly, concerning this issue, further research is needed to improve and clarify everyday clinical practice."],["dc.identifier.doi","10.1159/000501270"],["dc.identifier.pmid","31216545"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/84034"],["dc.language.iso","en"],["dc.notes.intern","DOI Import GROB-399"],["dc.publisher","S.

We first evaluated this novel technique in comparison to classical EMR in flat lesions. Methods The trial was prospectively conducted in an ex vivo animal model with porcine stomachs placed into the EASIE-R simulator. Prior to intervention, standardized lesions were set by coagulation dots, measuring 1, 2, 3 or 4 cm. Results Overall, 152 procedures were performed. EMR and EMR+ were both very reliable in 1-cm lesions, each showing en bloc resection rates of 100 %. EMR+ en bloc resection rate was significantly higher in 2-cm lesions (95.44 % vs. 54.55 %, P = 0.02), in 3-cm lesions (86.36 % vs. 18.18 %, P < 0.01) and also in 4-cm lesions (60.00 % vs. 0 %, P < 0.01). Perforations occurred only in EMR+ procedures in 4-cm lesions (3 of 20; 15 %). Conclusions With its grasp-and-snare technique, EMR+ facilitates en bloc resection of larger lesions compared to conventional EMR. In lesions 2 cm and larger, EMR+ has demonstrated advantages, especially concerning en bloc resection rate. At 3 cm, EMR+ reaches its best discriminatory power whereas EMR+ has inherent limits at 4 cm and in lesions of that size, other techniques such as ESD or surgery should be considered."],["dc.identifier.doi","10.1055/a-0996-8050"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/86831"],["dc.language.iso","en"],["dc.notes.intern","DOI-Import GROB-425"],["dc.relation.eissn","2196-9736"],["dc.relation.issn","2364-3722"],["dc.title","Endoscopic mucosal resection with an additional working channel (EMR+) in a porcine ex vivo model: a novel technique to improve en bloc resection rate of snare polypectomy"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]
