Key Points

To compare gel immersion endoscopic ultrasound (GI-EUS) with water immersion (WI) in visualizing the duodenal papilla and periampullary lesions.
Retrospective dual-center design
Blinded evaluation of archived endoscopic ultrasound videos
Comparison of visual clarity and stability between GI-EUS and WI
GI-EUS significantly improves ampullary delineation
GI-EUS exhibits enhanced liquid stability
Clinical utility of GI-EUS is supported for pancreatobiliary evaluations

Abstract

Compared with WI, GI-EUS significantly improves ampullary delineation with enhanced liquid stability and clarity, supporting clinical utility in pancreatobiliary EUS evaluations.
