in Gastrointestinal Endoscopy about the guidance for resuming GI endoscopy after the COVID-19 peak.
We resumed elective endoscopy procedures under our local infection control strategies (ICSs) in the Peking Union Medical College Hospital after the pandemic.

When the city of Beijing experienced an unexpected local outbreak with more than 300 clustered cases from the Xinfadi Market since June 10, 2020, we modified our ICSs to keep a sustainable and safe endoscopy service (Table 1).

Urgent procedures for acute GI bleeding, GI foreign body, acute cholangitis, and severe symptomatic obstructive jaundice due to gallstone or tumor, and acute luminal obstruction requiring stent placement; semiurgent procedure; semiurgent procedures for tumor diagnosis of highly suggestive cases and tumor staging; elective procedures for all other procedures, such as routine diagnostic or screening EGD and colonoscopy,
▪
Only urgent and semiurgent procedures accomplished
▪
Elective procedures postponed
▪
All procedures scheduled
▪
Stepwise resumption of daily work to full capacity
Full PPE includes disposable work cap, N95 respirators or equivalent, face shield/goggles, disposable protective clothing (AAMI level 3), double gloves and shoe covers; in standard PPE, surgical masks take the place of N95 respirators, and disposable gowns (AAMI level 1) take the place of disposable protective clothing (AAMI level 3).
▪
Full PPE for urgent procedure of COVID-19-positive patients
▪
Full PPE for upper GI endoscopy and standard PPE for colonoscopy in COVID-19 negative patients
▪
Full PPE for all endoscopies
Endoscopy room decontamination
▪
30 mins between each case
▪
Single-use bed sheet
▪
Surface contact with patients disinfected with chlorine-based solutions; endoscopy instruments disinfected with 75% alcohol
▪
HEPA device
▪
10 minutes between each case
▪
Surface contact with patients disinfected with CaviCide
CaviCide (Metrex Research, Michigan, USA) contains 0.25%-0.33% benzethonium chloride plus 15%-18% isopropanol, and both compositions are effective against COVID-19.
▪
The rest unchanged compared with “during pandemic”
▪
Unchanged compared with “postpandemic”
Note that other ICSs such as workplace arrangement and endoscope disinfection are sustained the same as those during the pandemic. We routinely follow up all patients for 14 days after procedures to rule out COVID-19.

Since early June 2020, we have turned to the new patient triage strategy of certificating infection risk by reverse-transcriptase polymerase chain reaction (RT-PCR) and epidemiologic history (Fig. 1) (for patient triage strategy during the pandemic, see Supplementary Fig. 1, available online at www.giejournal.org). Orofecal transmission during colonoscopy has never been really demonstrated, so it is reasonable that colonoscopy is regarded as of lower risk in terms of transmissibility than is upper GI endoscopy.

and we still wore N95 respirators for upper GI endoscopy but changed back to N95 respirators for all procedures after the local outbreak.
Figure 1Patient triage strategy by infection risk after COVID-19 pandemic and during local outbreak. Red arrows indicate flow of urgent cases. Blue arrows indicate flow of semiurgent and elective cases. If adequate FTOCC history and RT-PCR test cannot be acquired for emergency, all urgent cases should be considered COVID-19 positive for infection control, whose procedures should be accomplished in the negative pressure room. Ideally, RT-PCR test should be done within 2 days before procedure for reducing the infection risk between the test and procedure. During local outbreak, we added the “residence place triage” (green arrow): procedures of patients from intermediate or high-risk areas would be postponed except in urgent cases. Risk for different areas was declared by the local Municipal Health Commission. COVID-19, coronavirus disease 2019; FTOCC, fever, travel history to pandemic area, occupation, cluster of cases, contact with suspected or confirmed case.
Under the modified ICSs, we continue to provide 1497 cases of elective endoscopy, including 5 cases of endoscopic therapy for early GI cancer, and also 40 cases of urgent procedures during the local outbreak. There are no local outbreak-related cases in the work staff or patients in our endoscopy center. With the local outbreak in the decline trajectory, we returned to the ICSs in early June 2020 (the “postpandemic” strategy).
We suggest monitoring the pandemic closely and modifying the ICSs accordingly for recommencing GI endoscopy.

The rapid spread of coronavirus disease 2019 (COVID-19) has forced the temporary postponement of elective endoscopic procedures and nonessential GI office activity. As current containment measures take hold and the number of new COVID-19 cases is decreasing in some areas, GI practices need to plan for the gradual resumption of clinical operations. This must be achieved with the lowest possible risk of exposing patients, staff, and providers.
