Core Tip

Core Tip: Three-dimensional imaging allows easier identification of bile duct anatomy and intraoperative guidance of endoscopic retrograde cholangiopancreatography (ERCP). Continuous image-guided ERCP may be an effective means to assist the operator and reduce the use of X-ray and contrast agents.
