“…Second, the development and widespread use of various infection protection devices (e.g., mouthpieces, face masks, and face shields) may have had some effect on the maintenance of the number of endoscopy procedures in Japan, especially for EGD procedures. [17][18][19] Indeed, all the responding institutes followed the recommendation for the personal protective equipment proposed by JGES. 6 Since all GI cancers are exclusively diagnosed by endoscopic examinations with targeted biopsies, the potential decrease in the number of endoscopy procedures performed during the pandemic should inevitably lead to a decrease in the number of diagnosed GI cancers; this scenario is already supported by solid data from other countries.…”

ObjectivesThe 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.

“…Therefore, there has been an emphasis on the need for using personal protective equipment by healthcare professionals, including endoscopists [ 2 , 7 ]. Efforts have also been made to reduce virus transmission during endoscopy by using modified devices such as an endoscopic mouthpiece and a physical protective box [ 8 , 9 ].…”

“… 8 This has been shown to reduce aerosol scattering significantly, but not for aerosols ≤1.0 µm. 8 Hikichi et al, 10 in the latest issue of Clinical Endoscopy , reported on a novel mouthpiece which consisted of a conventional mouth guard and a hat-shaped attachment that has a large flange that covers the gaps between the mouth guard and angles of the mouth. This aerosol droplet guard acts as a valve that prevents aerosolized droplets being ejected from the mouth.…”

“…This aerosol droplet guard acts as a valve that prevents aerosolized droplets being ejected from the mouth. 10 There was another report on a very simple technique using a cut part of a rubber glove placed over the external part of the mouthguard to act as a valve. 11 We also considered this technique, but in our case the valve part was inverted inward ( Fig.…”
