Abstract
Background Biliary tract emergencies are managed with endoscopic retrograde cholangiopancreatography
(ERCP) using duodenoscopes, which are reusable devices that require high-level disinfection
to minimize risk of cross-contamination. Recent reports about newly developed single-use
duodenoscopes (SUDs) suggest equivalent performance with reusable duodenoscopes, but
the effectiveness of SUDs in emergency ERCP has not yet been studied.
Patients and methods We conducted a prospective case series of emergency ERCP procedures using SUDs (EXALT
model D-Boston Scientific, United States) in a real-life, tertiary care setting without
any possibility of using a back-up reusable duodenoscope.
Results Twenty-one emergent ERCPs (acute cholangitis 48%, severe jaundice 38 %, others 14 %)
were performed in 19 patients (mean age 49.5±15 years). Almost all procedures (20
of 21; 95 %) were technically and clinically successful, whereas selective cannulation
failed in one case. Among the successful ERCPs, five (24 %) were achieved by a novice
operator. The image was often considered skewed toward yellow tones (48 %), whereas
stiffness and pushability for stent insertion were found suboptimal in 5 % of the
procedures, without any impact on procedure success.
Conclusions SUDs are effective and appropriate devices for emergent situations in real life even
in non-expert hands and even if a regular duodenoscope is unavailable as a backup.
