Clinical Impact of Universal Screening for COVID-19 before Therapeutic Endoscopy

Abstract Introduction The Coronavirus pandemic (COVID-19) has led to drastic change in gastrointestinal (GI) endoscopy practice. Endoscopy is an aerosol-generating procedure. COVID-19 testing prior to endoscopy can reduce transmission by delaying non-emergency endoscopies in positive patients. There is scarcity of literature to support such protocols. We aimed to study the clinical impact of universal testing for COVID-19 before therapeutic endoscopy. Methods This is retrospective analysis of prospectively maintained data. All patients requiring therapeutic endoscopy were enrolled between June 15 to July 15, 2020. Clinical profile, indication, endoscopic intervention, and outcome of patients tested positive for COVID-19 real-time polymerase chain reaction (RT PCR) or CT chest suggestive of CO-RADS 3 or more were included for analysis. Results Out of 772 patients scheduled for endoscopic interventions, 26 (3.34%) patients had COVID-19 infection with mean age (range) of 48.19 (3–75) years. Eight (30.8%) were females. Of them, seven (26.9%) patients underwent emergency endoscopy, and another seven (26.9%) patients underwent endoscopy after minimum of 2 weeks waiting period. Two deaths were seen in patients who underwent emergency interventions which were unrelated to endoscopy. One patient, who was planned for endoscopic ultrasound (EUS) for choledocholithiasis, developed acute biliary pancreatitis in the waiting period. Conclusion We suggest use of universal testing for COVID-19 by RT-PCR before endoscopic intervention. Endoscopy can be postponed for 2 weeks with marginal risk of adverse events during the waiting period in nonemergency indications. However, this approach needs to be tailored as per local needs, resources availability, and indication of endoscopy.
