Summary

This study looked at how well a single-use duodenoscope (called Exalt D) works for ERCP procedures in China. The goal was to see if it could complete the procedure without needing a reusable scope. Up to 35 adults scheduled for ERCP were planned to take part, but the study was withdrawn before any participants enrolled.
