Investigation of factors related to successful puncture of the intrahepatic bile duct in endoscopic ultrasound-guided biliary drainage

Puntos clave

• Successful bile duct puncture relies on the angle of the scope and puncture needle, influencing overall outcomes.
• A strong up-angle applied to the scope can enhance the success rate, with lower elevator usage favoring this technique.
• Evaluation of these methods during endoscopic ultrasound-guided biliary drainage provides insights into effective practices.
• Further exploration of these angles and techniques could lead to higher success rates in clinical settings.
