Endoscopic Procedures V: ERCP

Endoscopic Procedures V: ERCP

Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

Area of Science:

Medical robotics
Surgical instrumentation
Endoscopic procedures

Background:

Advanced flexible endoscopes with multiple degrees of freedom facilitate complex procedures like large tissue removal.
Current advanced endoscopes present significant control challenges, often necessitating multiple physicians.

Purpose of the Study:

To introduce a novel robotic system for intuitive control of flexible endoscopic instruments.
To compare the performance of the robotic system against conventional control methods.

Main Methods:

A human subjects experiment was conducted comparing robotic and conventional control methods.
Participants controlled an instrument via a haptic device using the robotic system.
Performance was evaluated by task completion time in target-tapping exercises under direct and monitor viewing conditions.

Main Results:

Subjects using the robotic control method completed the task significantly faster (54 seconds) compared to conventional methods (164 seconds).
Performance showed significant improvement from the first trial to the second trial, indicating a learning effect.

Conclusions:

The developed robotic control method offers a viable solution for enhancing physician performance with advanced flexible endoscopes.
This technology has the potential to improve efficiency and outcomes in challenging endoscopic interventions.
