Current status of direct peroral cholangioscopy

Area of Science:

• Gastroenterology
• Endoscopic Procedures

Background:

• Direct peroral video cholangioscopy is increasingly recognized for diagnosing and treating bile duct lesions.
• Current methods often use ultra-slim endoscopes, but direct insertion without assistance is challenging.

Purpose of the Study:

• To address the difficulties associated with direct scope insertion in peroral video cholangioscopy.
• To explore reliable methods for facilitating cholangioscope insertion into the bile duct.

Main Methods:

• Review of existing literature on endoscopic techniques for bile duct access.
• Introduction of a novel prototype cholangioscope featuring a short bending section and an anchoring balloon catheter.
• Evaluation of the potential for balloon-assisted scope insertion and replacement.

Main Results:

• Intraductal balloon catheter-assisted scope insertion is suggested as a reliable method based on prior literature.
• A new prototype cholangioscope has been developed to specifically overcome insertion challenges.
• The prototype incorporates features for enhanced scope maneuverability and secure placement.

Conclusions:

• The development of advanced cholangioscopes is crucial for overcoming technical barriers in direct peroral cholangioscopy.
• Future advancements in endoscopic technology are expected to establish more effective direct peroral cholangioscopy procedures.
• The prototype cholangioscope shows promise for routine clinical adoption in diagnosing and treating bile duct pathologies.
