The tip of the ultra-slim ultrasonic probe emerges from the tip of the outer sheath (blue arrow) of the Endosheather. b The Y-connector with a 10-Fr internal lumen is attached to the proximal end of the outer sheath (red arrow). The ultra-slim ultrasonic probe (yellow arrow) is inserted through the Y-connector and outer sheath.

The inside of the bile duct cannot be observed due to air bubbles. b After air bubbles are aspirated and saline-diluted contrast medium diluted is injected through the Endosheather, the inside of the bile duct can be clearly observed.
