We read with great interest the recent articles by Repici et al1 and Soetikno et al.2 An outbreak of
a novel coronavirus pneumonia has rapidly spread through the whole country and is now a
worldwide pandemic. Up to March 30, the National Health and Health Commission of China has
reported a total of 82,423 confirmed cases in 31 provinces, 3306 cases of deaths, and total 615,699
confirmed cases worldwide.3 With the development of the pandemic, more countries have become
involved in this serious battle against the virus.
ERCP is an important and effective procedure of choice for biliary decompression. Despite the
highly infectious danger in COVID-19 outbreak areas, ERCP is still required for patients with
emergent biliary obstruction and for those who cannot wait until the next available elective list.
Direct contact, airborne droplets and touch contamination, and uncertain fecal-oral transmission
greatly increase the infection risk of ERCP procedures.4
To guarantee the safety of healthcare workers and patients for ERCP procedures, we established
infection prevention measures and standard operating procedures in our endoscopy center of
gastroenterology department to guarantee a safe environment to protect both patients and
healthcare personnel. Here, we retrospectively reviewed ERCP procedures in 31 patients during
the pandemic of COVID-19 to evaluate the safety and essential protection measures.
Patients with acute obstructive cholangitis, aggravated bile duct obstruction (rapid increased serum
total bilirubin [TBIL]), acute biliary pancreatitis, and common bile duct (CBD) gallstones with
fever, abdominal pain, and jaundice received ERCPs during the outbreak. COVID-19 screening
examinations including chest CT scans, complete blood tests, virological nuclei acid PCR tests
(nasal and oropharyngeal swab samples), and COVID-19 IgM/IgG were mandatory for all patients
and the people accompanying those patients before ERCP, except for emergent cases. COVID-19

patients were admitted in designated wards. Other patients negative to COVID-19 infection spent
6 days of observation and preparation to transfer from 2 buffer zone wards (with 3 days of
observation per ward) to GI department wards. COVID-19–related symptoms including fever,
cough, chest pain, and dyspnea were kept under observation during the whole hospitalization, and
COVID-19 screenings were considered once these alert symptoms were presented. The study
protocol was approved by the ethics committee of Renmin Hospital of Wuhan University, and
waiver of informed consent was obtained (ID: WDRY2020-K075). All ERCPs were performed
with the patient under conscious sedation with propofol and pethidine, and the patient was
monitored by an anesthesiologist or endoscopist during the procedures.
After ERCPs, COVID-19 patients returned to designated wards, and uninfected patients were
admitted back to the buffer zone or GI wards for further treatments and observations.
During the outbreak of COVID-19 in Wuhan, from February 1 to March 31, 31 ERCPs were
performed for hospitalized patients admitted in Renmin Hospital of Wuhan University. The
median age of patients was 61 years (range 40-84 years) with the majority being male patients (19
M:12 F). Most patients had comorbidities, and up to 41.9% of patients had hypertension. Anorexia
(29 [93.4%]), fatigue (29 [93.4%]), and jaundice (23 [74.2%]) were the common symptoms. A
total of 19.4% of patients (6 cases) had fever, and 35.5% (11 patients) had abdominal pain. The
indications that necessitated ERCP included CBD gallstones (15 [48.4%]), acute biliary
pancreatitis (5 [16.1%]), and carcinoma (cholangiocarcinoma [8, 25.8%], ampullary cancer [1,
3.2%], and duodenal papillary carcinoma [2, 6.5%]). Most patients (21 [67.7%]) underwent
COVID-19 screening and then were admitted to wards by transferring from buffer zones to the GI
department, whereas 32.3% of patients (10 cases) finished the screening post-ERCP for emergent

situations, including acute obstructive cholangitis and acute biliary pancreatitis (5 cases [16.1%],
respectively).
One patient who underwent emergent ERCP tested positively to COVID-19 nuclei acid in
oropharyngeal swab samples taken right before the procedure. This patient was later confirmed as
an asymptomatic carrier of COVID-19. At the time of this manuscript submission, none of the
other patients, their accompanying persons, or healthcare workers in our endoscopy center were
reported to have the COVID-19 infection.
In the current new era of the COVID-19 outbreak and rapidly evolving epidemiology, hospitals
have become one of the highest-risk places for both healthcare personnel and patients. With the
dramatic development of this pandemic, the risk of aerosol-generating medical procedures
(AGMPs) gained extensive attention, especially for upper endoscopic procedures, including
esophagogastroduodenoscopy (EGD), ERCP, and EUS, which carry the highest risk of aerosols.
Current guidelines and consensus recommended that patient management should be based on the
risk assessment of the COVID-19 infection, which included the patient’s exposure history (if he
stayed in a high-risk area during the previous 14 days and had contact with an infected person) and
typical symptoms regarding fever, cough, breathlessness, and diarrhea. Personal protective
equipment (PPE) were suggested to be provided accordingly. 5 However, given that atypical
symptoms without fever and respiratory presentations and current community transmission from
asymptomatic patients with COVID-19 have already been documented (and false-negative results
of virological test in some cases), it is challenging to identify all COVID-19 patients before ERCP
procedures. Furthermore, for patients who needed urgent ERCP, fever, abdominal pain, anorexia,
and diarrhea were common seen and greatly increased the complexity of differentiation. Therefore,
in the standard operating procedure of our ERCP team, we regarded all new patients as potential

COVID-19 candidates regardless of whether the patients were considered low or high risk for
COVID-19.
Although all patients were asked to screen for COVID-19 before ERCP, some emergent cases
could not wait for the results. In these emergent cases, samples were taken for virus screening right
before the procedure. It is important to differentiate community infection from nosocomial
infection of the virus. One COVID-19 patient was confirmed in the first buffer zone ward after the
ERCP procedure and was confirmed as having a community infection. Our measurements
successfully identified this infected patient and prevented risky transmission. By the date of this
article submission, no other patients, accompanying people, or medical workers in our endoscopic
center were reported and diagnosed as having the COVID-19 infection.
In conclusion, our measures guaranteed that all healthcare workers in our endoscopy center,
patients, and accompanying persons would avoid COVID-19 infection and successfully identified
a virus-infected case during the procedure. Our experiences and measures for ERCP would help
others to establish optimal measures or standard operating procedures to avoid further
unrecognized spread of the disease.
