The extent of adoption, patient selection, and use patterns of single-use duodenoscopes and duodenoscopes with single-use endcaps have not yet been characterized, and large-scale assessments of endoscopist-reported function and challenges have not been reported.

An anonymous 6-minute electronic survey assessing use and experience with single-use duodenoscopes and duodenoscopes with novel design features was distributed to U.S. and Canadian endoscopy centers, and responses were analyzed using descriptive statistics.

The survey was notable for a 70.2% response rate, with representation from academic (68.9%), community (18%), and veterans affairs (8.2%) centers. Most institutions used standard reprocessable duodenoscopes and duodenoscopes with single-use endcaps (34.4%) or a mix of standard reprocessable duodenoscopes, duodenoscopes with single-use endcaps, and single-use duodenoscopes (29.5%). No center used only single-use duodenoscopes. Some institutions (10.3%) planned to transition to duodenoscopes with a single-use endcap, 10.3% to a mix of single-use duodenoscopes and duodenoscopes with a single-use endcap, and 1.7% to single-use duodenoscopes alone. Challenges were reported with each type of novel duodenoscope, and selection patterns for use were characterized.

This first of its kind, large-scale survey of use patterns and functionality of newly introduced duodenoscopes is notable for the fairly widespread use of duodenoscopes with single-use endcaps and more limited use of single-use duodenoscopes. Both novel duodenoscope designs are associated with mechanical limitations that respondents indicate represent challenges to successful completion of ERCPs.
