BACKGROUND: ERCP is an advanced endoscopic technique that involves fluoroscopy, and as such it may pose a risk of occupational radiation exposure for medical personnel. This technique also places high demands on the operator's hand dexterity and stability due to its significant technical complexity.
METHODS: To address these issues, we developed a robotic system named "Qifengda" to assist in ERCP procedures. A novel robotic system for flexible endoscopy was developed in this study, and its feasibility for assisting endoscopists in ERCP procedures was evaluated in a porcine model.
RESULTS: Successful cannulation, cholangiography, and biliary stent placement were performed using this robotic system, without any significant procedure-related adverse events.
DISCUSSION: This preclinical pilot study supports proof-of-concept of this robotic endoscopic system for assisting endoscopists in ERCP procedures. In future studies, we will further validate the feasibility and safety of this system in human subjects.
