The main objectives of this study were to investigate trends in EGD utilization and mortality related to it in a national low-threshold healthcare system, assess perioperative safety, and identify and describe patient-reported malpractice claims from the national database. <b>Patients and methods</b> We retrospectively identified patients from the Finnish Patient Care Registry who underwent diagnostic or procedural EGD between 2010 and 2018.

Disinfection has been shown to have a significant risk of failure with serious consequences. Single-use endoscopes can eliminate contamination risk and reduce workflow delays caused by reprocessing. This study evaluated the clinical performance of single-use gastroscopes in patients undergoing esophagogastroduodenoscopy (EGD). <b>Patients and methods</b> In this case series, 60 patients underwent EGD using single-use gastroscopes, with 34 procedures in the endoscopy department and 26 in the intensive care unit.
