Impact of the COVID‐19 pandemic on the performance of endoscopy in the Tohoku region of Japan

Abstract

AbstractObjectivesThe whole picture of the disturbance in endoscopy performance caused by the coronavirus disease 2019 (COVID‐19) pandemic in Japan remains to be clarified. Therefore, the Japan Gastroenterological Endoscopy Society‐Tohoku conducted this questionnaire survey in Tohoku region of Japan.MethodsA questionnaire on the number of diagnostic endoscopy procedures and resulting diagnosed cancers in 2019 and 2020 was sent to all guidance/guidance cooperation hospitals in the Japan Gastroenterological Endoscopy Society who worked in the Tohoku region. The percentage change was calculated by comparing the numbers in 2020 with those in 2019 (the pre‐COVID‐19 period).ResultsAmong the applicable 89 guidance/guidance cooperation hospitals, 83 (94%) returned the questionnaire. The number of endoscopy procedures promptly decreased to the nadir in April and May 2020 (during the first state of emergency in Japan); however, it recovered relatively quickly, within a few months after the state of emergency was lifted. Consequently, the annual reduction in the number of endoscopy procedures in 2020 (in comparison to 2019) was 10.1% for esophagogastroduodenoscopy and 7.9% for colonoscopy. The reduction in the number of diagnostic endoscopy procedures led to a 5.5% reduction in esophagogastric cancer and 2.7% in colorectal cancer.ConclusionsThis is the most comprehensive survey on the impact of the COVID‐19 pandemic on the performance of endoscopy and the resulting diagnosis of cancer in Japan. Understanding the magnitude of the decline in endoscopic examinations and cancer detection due to the pandemic is critical to understanding how many people will ultimately be affected and establishing a strategy for providing endoscopy during national emergencies.
