A new robotic system, Qifengda, shows promise for assisting in endoscopic retrograde cholangiopancreatography (ERCP). This pilot study found the system feasible and convenient, potentially reducing radiation exposure for endoscopists.
Area of Science:
- Medical Robotics
- Gastroenterology
- Endoscopic Procedures
Background:
- Development of the "Qifengda" robotic endoscopic system to aid in Endoscopic Retrograde Cholangiopancreatography (ERCP).
- Aims to reduce occupational radiation exposure for endoscopists during ERCP procedures.
- Pilot trial to assess the feasibility and clinical potential of the robotic system.
Purpose of the Study:
- Evaluate the technical and clinical success rates of robot-assisted ERCP.
- Assess ERCP-related complications, system convenience, and stability.
- Investigate procedure time, postoperative hospital stay, and hospitalization costs.
Main Methods:
- Prospective recruitment of 13 patients in a single tertiary hospital.
- Robot-assisted ERCP procedures were performed.
- Primary endpoints: technical and clinical success. Secondary endpoints: complications, system usability, procedure duration, and costs.
Main Results:
- 100% technical success rate in all 13 patients.
- Therapeutic goals achieved in 12 patients; median procedure time of 38 minutes.
- Low complication rates (1 mild pancreatitis, 1 moderate cholangitis); high operator satisfaction with system convenience and stability.
Conclusions:
- Initial outcomes support the procedural feasibility of the Qifengda robotic system for ERCP.
- The system demonstrates potential to assist endoscopists, possibly reducing radiation exposure.
- Larger studies are needed to confirm these findings in a broader patient population.
