Robotic-Assisted Bile Duct Cannulation During Endoscopic Retrograde Cholangiopancreatography: A Randomised Controlled...

Area of Science:

• Gastroenterology
• Medical Robotics
• Surgical Innovation

Background:

• Endoscopic retrograde cholangiopancreatography (ERCP) presents significant technical challenges, including radiation exposure and a steep learning curve for endoscopists.
• The need for improved safety and efficiency in ERCP procedures drives the development of robotic solutions.

Purpose of the Study:

• To evaluate the feasibility, safety, and efficacy of robotic-assisted ERCP.
• To compare robotic-assisted ERCP with traditional manual techniques in an animal model.

Main Methods:

• A randomized controlled crossover study involving three experienced endoscopists performing 12 robotic-assisted and 12 manual ERCP procedures on beagles.
• The YunSRobot system was utilized for robotic-assisted procedures.
• Primary outcomes measured were papilla positioning maintenance, cannulation time, and success rate.

Main Results:

• Robotic-assisted ERCP demonstrated significantly superior papilla positioning (95.74% vs. 77.25%, p < 0.01), indicating enhanced endoscopic stability.
• Successful cannulation rates were comparable between robotic (83.3%) and manual (83.3%) groups.
• The robotic approach required fewer cannulation attempts (2.0 vs. 3.5) and resulted in zero scope dislocations compared to five in the manual group.

Conclusions:

• Robotic-assisted ERCP is a feasible, safe, and effective alternative to manual ERCP.
• The robotic system provides significantly improved endoscopic stability during procedures.
• This technology holds promise for enhancing ERCP outcomes and potentially reducing procedural risks.
