The Hooking Technique for Retrograde Freehand Access during Direct Cholangioscopy (with Video)

Area of Science:

• Gastroenterology
• Hepatology
• Endoscopic Procedures

Background:

• Direct cholangioscopy allows for in-situ examination of the bile duct.
• Achieving retrograde freehand access can be challenging, potentially limiting diagnostic and therapeutic interventions.

Purpose of the Study:

• To describe and evaluate the novel Hooking Technique for retrograde freehand access during direct cholangioscopy.
• To demonstrate the utility of this technique in achieving optimal visualization and access within the biliary tree.

Main Methods:

• The Hooking Technique involves a specific maneuver to engage the biliary confluence.
• This technique was applied during direct cholangioscopy procedures.
• Video documentation illustrates the procedural steps and outcomes.

Main Results:

• The Hooking Technique facilitates successful retrograde freehand access in a retrograde fashion.
• The technique provides enhanced maneuverability and stable positioning of the cholangioscope.
• Improved visualization of the biliary tree was achieved using this method.

Conclusions:

• The Hooking Technique is a valuable addition to the armamentarium for direct cholangioscopy.
• This method offers a reliable approach for achieving retrograde freehand access, potentially improving patient outcomes.
