Pre-endoscopy SARS-CoV-2 testing strategy during COVID-19 pandemic: The care must go on

BackgroundIn response to the COVID-19 pandemic, endoscopic societies have recommended reduction of endoscopic procedures. In particular non-urgent endoscopies should be postponed. However, this might lead to unnecessary delay in diagnosing gastrointestinal conditions.MethodsRetrospectively we analysed the gastrointestinal endoscopies performed at the Central Endoscopy Unit of Saarland University Medical Center during seven weeks from 23 March to 10 May 2020 and present our real-world single-center experience with an individualized rtPCR-based pre-endoscopy SARS-CoV-2 testing (“PECo”) strategy.ResultsAltogether 359 gastrointestinal endoscopies were performed. The PECo strategy enabled us to conservatively handle endoscopy program reduction (44% reduction as compared 2019). The results of COVID-19 rtPCR from nasopharyngeal swabs were available in 89% of patients prior to endoscopies. Apart from six patients with known COVID-19, all other tested patients were negative. The frequencies of endoscopic therapies and clinically significant findings did not differ between patients with or without SARS-CoV-2 tests.ConclusionA reasonable reduction of the endoscopy program in the setting of structured SARS-CoV-2 testing is feasible and safe. The PECo strategy allows continuation of endoscopic procedures in a region with intermediate frequency of COVID-19 when hospital capacities are not overwhelmed by the pandemic. Thus, the study might help to develop new strategies during future waves of COVID-19 or local outbreaks.
