ARTICLE HIGHLIGHTS
Research background
Three-dimensional (3D) imaging is beneficial in guiding therapeutic endoscopic retrograde cholangiopancreatography (ERCP), reducing the radiation dose and procedure time while increasing overall procedure safety. However, current 3D biliary imaging does not have good real-time fusion with intraoperative images.
Research motivation
We explored the feasibility of real-time continuous image-guided ERCP, which was shown to overcome the influence of intraoperative respiratory motion and provides an accurate navigation method.
Research objectives
To explore the feasibility of real-time continuous image-guided ERCP.
Research methods
We simulated an ERCP environment using an experimental biliary phantom with the aim of designing a navigation system; this system was further tested in patients undergoing ERCP.
Research results
Continuous image-guided ERCP was applied in the biliary phantom with low registration and tracking errors. This 3D/2D registration accurately transformed preoperative 3D biliary images to each image in the X-ray sequence in real-time.
Research conclusions
Continuous image-guided ERCP may be an effective approach to assist the operator and reduce the use of X-ray and contrast agents.
Research perspectives
Clinical studies are needed to determine if this image-guided ERCP strategy could improve technical success while reducing radiation exposure and contrast agent administration during ERCP.
