Hiatal Hernias Revisited-A Systematic Review of Definitions, Classifications, and Applications.

Introduction: A hiatal hernia (HH) can be defined as a condition in which elements from the abdominal cavity herniate through the oesophageal hiatus in the mediastinum and, in the majority of cases, parts of the proximal stomach. Today, the role of HHs within the complex entity of gastroesophageal reflux disease (GERD) is very important with regard to its pathophysiology, severity, and therapeutic and prognostic options. Despite this, the application and stringent use of the worldwide accepted classification (Skinner and Belsey: Types I-IV) are lacking.

Innovations in GI-endoscopy.

Gastrointestinal endoscopy covers both diagnosis and therapy. Due to its diagnostic accuracy and minimal invasiveness, several innovations have been made within the last years including artificial intelligence and endoscopic tumor resection. The present review highlights some of these innovation.

[Interpretation und performance of high-resolution esophageal manometry: Recommendations of the German Association of Neurogastroenterology and Motility (DGNM) and the German Association of Gastroenterology, Digestive and Metabolic Diseases (DGVS)].

Esophageal manometry provides a detailed evaluation of esophageal contractility and, therefore, represents the reference method for diagnosis of esophageal motility disorders. Significance and clinical relevance have been further increased by implementation of high-resolution esophageal manometry (HRM), which reveals the functional anatomy of the esophagus in a visually-intuitive manner. The current 3 rd version of the international Chicago Classification (CC v3.

EAES recommendations for the management of gastroesophageal reflux disease.

Background: Gastroesophageal reflux disease (GERD) is one of the most frequent benign disorders of the upper gastrointestinal tract. Management of GERD has always been controversial since modern medical therapy is very effective, but laparoscopic fundoplication is one of the few procedures that were quickly adapted to the minimal access technique. The purpose of this project was to analyze the current knowledge on GERD in regard to its pathophysiology, diagnostic assessment, medical therapy, and surgical therapy, and special circumstances such as GERD in children, Barrett's esophagus, and enteroesophageal and duodenogastroesophageal reflux.

EAES recommendations on methodology of innovation management in endoscopic surgery.

Background: Under the mandate of the European Association for Endoscopic Surgery (EAES) a guideline on methodology of innovation management in endoscopic surgery has been developed. The primary focus of this guideline is patient safety, efficacy, and effectiveness.

Methods: An international expert panel was invited to develop recommendations for the assessment and introduction of surgical innovations.

Candida-induced stomatopyrosis and its relation to diabetes mellitus.

Background: Glycaemic disorders and oral candidosis can be accompanied by burning mouth sensations. However, no clear relation between all three disorders is known.

Methods: Seventy-two native Upper-Austrians with burning mouth sensations were examined and smears for Candida estimation were taken from the spots where the sensations were felt.

Bacterial adhesion to sulcular epithelium in periodontitis.

The purpose of this study was to investigate, by electron microscopy, the type of bacterial attachment to the sulcular epithelium in periodontitis. Gingiva biopsies were observed in a transmission electron microscope using cytochemical staining with ruthenium red for glycocalyx visualisation. In addition, subgingival plaque samples and biopsies from the sulcular epithelium in periodontitis from the patients were estimated microbiologically.
