Functional gastrointestinal disorders such as functional dyspepsia (FD) and irritable bowel syndrome (IBS) are stress-associated. The COVID-19 pandemic, which has been rampant since 2020, has caused anxiety and stress in the population. Distancing measures to combat the pandemic have affected mental health. Our objective was to examine the impact of the 3rd lockdown in Germany in December 2020 and January 2021 on the apprehension of patients with FD and IBS.Patients diagnosed with FD or IBS treated in a tertiary or primary care hospital in the South of Baden-Württemberg in 2020 voluntarily participated in an anonymous online survey. Questions about concomitant diseases, concern about COVID-19 and stress perception were answered.A total of 106 patients (♀=67, ♂=38, 1 diverse) participated in the survey. Of these, 16 had FD (♀=9, ♂=6, diverse=1), 80 had IBS (♀=52, ♂=28), and 10 had both (♀=6, ♂=4). The average age was 43.6 years. Depressive and anxiety disorders were most frequently reported comorbidities in both the FD (25% each) and IBS group (20% each), followed by joint wear and tear (FD: 13%, RDS: 14%). In a direct comparison of participants with FD and IBS, those with IBS showed significantly higher scores for an increase in gastrointestinal (GI) symptoms during the pandemic (p=0.007), more frequent presentation to a physician during the pandemic, and greater social withdrawal due to GI symptoms (p=0.05). In direct comparison, those with IBS showed higher scores for fear that vaccination against COVID-19 would adversely affect GI symptoms compared to FD (p=0.05).In times of the pandemic, interdisciplinary collaboration in the care of patients with FD or IBS seems more necessary than ever to address concerns and provide good patient care., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

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 v3.0) gives standardized recommendations on performance and interpretation of HRM and serves as the basis for much of this expert consensus document. However, CC v3.0 gives only limited information with regards to the function of the lower and upper esophageal sphincters, the use of adjunctive tests including solid test meals and long-term ambulatory HRM measurements. In this expert consensus, we describe how to perform and interpret HRM on the basis of the CC v3.0 with additional recommendations based on the results of recent, high-quality clinical studies concerning the use of this technology to assess the causes of esophageal symptoms in a variety of clinical scenarios., Competing Interests: JK: Finanzielle Unterstützung für Forschungsvorhaben und Durchführung von Fortbildungsveranstaltungen sowie Honorare für Vorträge von Given Imaging/Medtronic und Standard Instruments.MF: Finanzielle Unterstützung für Forschungsvorhaben und Durchführung von Fortbildungsveranstaltungen sowie Honorare für Vorträge oder Teilnahme an Advisory Board-Sitzungen von Given Imaging / Medtronic, Medical Measurement Systems, Sandhill Scientific Instruments und Mui Scientific.Bei den anderen Autoren bestehen keine potenziellen Interessenkonflikte., (© Georg Thieme Verlag KG Stuttgart · New York.)

The current recommendations on indications, technical performance, and interpretation of diagnostic techniques for oesophageal reflux update the German recommandations about 24 hour pH measurement of 2003. The recommendations encompass conventional pH measurement, wireless pH measurement, pH and impedance measurements, and bilirubin measurement (duodenogastro-oesophageal reflux)., (© Georg Thieme Verlag KG Stuttgart · New York.)
