“…Several methods for shielding patients during endoscopy have previously been reported [25][26][27][28][29][30][31], including a transparent plastic box and a vinyl sheet, both of which cover the patient. However, these devices need to be cleaned and disinfected if they are reused.…”

Background and study aims Infection control is essential when performing endoscopic procedures, especially during the COVID-19 pandemic. Therefore, we have developed a new shielding device called STEP for infection control in upper gastrointestinal endoscopy. Patients and methods STEP consists of a mask worn by the patient and a drape that is connected to the mask and covers the endoscope. A suction tube attached to the mask prevents aerosols from spreading. The endoscopist operates the endoscope through the drape. Three endoscopists performed a total of 18 examinations using an upper endoscopy training model with and without STEP. Endoscopic images were evaluated by three other endoscopists, using a visual analog scale. We also simulated contact, droplet, and aerosol infection and evaluated the utility of STEP. Results All examinations were conducted without a problem. Mean procedure time was 126.3 ± 11.6 seconds with STEP and 122.3 ± 10.0 seconds without STEP. The mean visual analog score was 90.7 ± 10.1 with STEP and 90.4 ± 10.0 without STEP. In the contact model, adherence of simulated contaminants was 4.9 ± 1.4 % without STEP and 0 % with STEP. In the droplet model, the number of simulated contaminants attached to the paper was 338 273 ± 90 735 pixels without STEP and 0 with STEP. In the aerosol model, the total number of particles was 346 837 ± 9485 without STEP and was significantly reduced to 222 ± 174 with STEP. Conclusions No effect on examination time or endoscopic image quality was observed when using STEP in upper gastrointestinal endoscopy. Using STEP reduced the diffusion of simulated contaminants in all three infection models.

“…As a result, endoscopy staff are likely to be infected with the SCV2 during EGD through discharge of aerosol droplets. The main source of aerosol droplets containing SCV2 during EGD is the mouth, and some countermeasures have been reported 3–5 . We developed a novel method using a mask plus vinyl bag (two‐stage blocking system; Fig.…”

Emergency upper gastrointestinal endoscopy performed safely in a patient with COVID‐19 with suspected hemorrhagic shock

Coronavirus disease 2019 caused by severe acute respiratory syndrome coronavirus 2 has spread explosively throughout the world and has since been declared a pandemic by the World Health Organization. Although it is recommended that upper gastrointestinal endoscopies either be postponed or canceled during the pandemic because of their high risk of aerosol generation, this does not apply in emergency cases, which may include patients with coronavirus disease. In this case report, we describe the safe undertaking of an emergency upper gastrointestinal endoscopy in a patient with suspected hemorrhagic shock who tested positive for the severe acute respiratory syndrome coronavirus 2 using the polymerase chain reaction. We performed the procedure in the contamination zone of a specialized coronavirus disease ward with prespecified zones. Full personal protective equipment was worn during the procedure, as recommended by various academic societies, and careful attention was paid to the sterilization of all equipment after the procedure. Thus, emergency endoscopies can be performed safely in patients with coronavirus disease in a suitable environment by using appropriate personal protective equipment and by handling the equipment appropriately.
