“…Given the above-mentioned risks, various professional gastroenterological organisations, represented by the Asian Pacific Society for Digestive Endoscopy and American Society for Gastrointestinal Endoscopy (ASGE),16–19 have strongly recommended that medical staff using proper personal protective equipment (PPE), especially surgical mask/N95 respirators or equivalent during OGD procedures. Many regional surveys and the experience of medical centres and specialists have demonstrated that there is widespread support for these recommendations 9 20–23. In addition, wearing PPE does not affect the objective physiological state of medical staff during OGD procedures or the success of such procedures 24 25.…”

BackgroundAerosol-generating procedures such as oesophagogastroduodenoscopy (OGD) result in infectious particles being exhaled by patients. This substantially increases the medical staff’s risk of occupational exposure to pathogenic particles via airway inhalation and facial mucosal deposition. Infectious particles are regarded as a key route of transmission of SARS-CoV-2 and, thus, represents a major risk factor for medical staff during the ongoing COVID-19 pandemic. There is a need for quantitative evidence on medical staff’s risk of multiroute exposure to infectious particles exhaled by patients during OGD to enable the development of practical, feasible and economical methods of risk-reduction for use in OGD and related procedures. This randomised controlled trial (RCT)—Personal protective EquiPment intervention TrIal for oesophagogastroDuodEnoscopy (PEPTIDE)—aims to establish a state-of-the-art protocol for quantifying the multiroute exposure of medical staff to infectious particles exhaled by patients during real OGD procedures.Method and analysisPEPTIDE will be a prospective, two-arm, RCT using quantitative methods and will be conducted at a tertiary hospital in China. It will enrol 130 participants (65 per group) aged over 18. The intervention will be an anthropomorphic model with realistic respiratory-related morphology and respiratory function that simulates a medical staff member. This model will be used either without or with a surgical mask, depending on the group allocation of a participant, and will be placed beside the participants as they undergo an OGD procedure. The primary outcome will be the anthropomorphic model’s airway dosage of the participants’ exhaled infectious particles with or without a surgical mask, and the secondary outcome will be the anthropomorphic model’s non-surgical mask-covered facial mucosa dosage of the participants’ exhaled infectious particles. Analyses will be performed in accordance with the type of data collected (categorical or quantitative data) using SPSS (V.26.0) and RStudio (V.1.3.959).Ethics and disseminationEthical approval for this RCT was obtained from the Ethics Committee of Peking Union Medical College Hospital (ZS-3377). All of the potential participants who agree to participate will provide their written informed consent before they are enrolled. The results will be disseminated through presentations at national and international conferences and publications in peer-reviewed journals.Trial registration numberNCT05321056.

“…Furthermore, before the outbreak of SARS-CoV 2, a patient in isolation for any multi-resistant microorganism was accurately and safely transported to the endoscopic theater at the endoscopic service while taking proper precautions. This strategy was initially not applicable to SARS-CoV 2-positive patients, so when the pandemic globally spread, many departments changed their management strategies, and most of the hospitals adapted their facilities to the ongoing condition [4,5].…”

Endoscopy at Bedside in Isolated Patients with Severe COVID-19: Our Approach during the Pandemic

The COVID-19 pandemic changed the management of emergency medicine and those complications that needed interventional procedures, such as endoscopy or other radiological procedures. At the beginning of the outbreak, there were no exploitable recommendations regarding the proper policy to apply for limiting the virus spread during endoscopy. Between the first and the second wave, the approach regarding interventional procedures changed, due to higher awareness and newly defined protocols, even if different among the health centers. Patients with severe COVID-19 may develop major gastrointestinal complications or require nutritional support, so interventional procedures are required at bedside, even if patients are in isolated rooms. Our tertiary center admitted 95 patients with severe COVID-19 at our ICU-dedicated department until May 2021, and 56% of them died. Among them, 61 endoscopic procedures were performed, mainly gastroscopies (81.96%) followed by colonoscopies (11.47%) and other more advanced procedures (6.55%). Our approach aimed to adapt and create COVID-related protocols, dedicated itineraries, and rooms in a separate department with the prospect to easily organize complete and safe endoscopic theaters at the COVID-ICU department.
