Should the Endoscopic Restrictions during COVID-19 Pandemic Remain Unchanged?

Abstract

(Background) Endoscopic procedures are interventions that have been defined as carrying a high-risk of infection with COVID-19. Most endoscopy units restrict their activity based on pre-endoscopic diagnosis. (Objective) To determine the consequences of endoscopic restrictions as a result of the COVID-19 pandemic and their impact on digestive cancer diagnosis. (Design) A comparison of upper digestive endoscopies and colonoscopies with gastrointestinal cancers diagnosed between three endoscopic centers, two of which restricted their procedures and one that did not but performed the procedures under a strict protocol. (Setting) A retrospective analysis was performed collecting data between 15 March 2019 and 15 August 2020. Two-factor ANOVA and a Tukey’s a posteriori test were used as statistical tests. (Main outcome measures) There was variation in gastrointestinal cancer diagnosis between 2019 and 2020, considering the endoscopic procedures performed each year. (Result) There was a significant decrease in the total endoscopic procedures performed between 2019 and 2020 (p p p = 0.139). Regarding the total cancers diagnosed, while a significant decrease was observed for the two centers with pre-endoscopic restrictions (p = 0.007), a significant increase was registered in the center that maintained its endoscopic productivity (p (Conclusion) Endoscopic restrictions based on pre-endoscopic diagnosis should be reassessed in consideration of local pandemic situations, and a balance should be sought between COVID-19 infection risk and the detrimental delay of potential cancer diagnosis.
