Feasibility of Endoscopic Ultrasound Based Biliary Stone Removal Without Fluoroscopy

Feasibility of Endoscopic Ultrasound Based Biliary Stone Removal Without Fluoroscopy

To assess the feasibility and success of endoscopic ultrasound (EUS) directed biliary stone removal without use of fluoroscopy. Success for this study will be defined as the successful removal of all stones from the bile duct without the use of fluoroscopy. Fluoroscopy will only be used at the end of a presumed successful procedure to confirm that all stones are removed.

Inclusion Criteria:

• Patients able to give informed consent
• Patients referred to IES for the endoscopic evaluation and treatment of suspected bile duct stones

Exclusion Criteria:

• Patients with >3 bile duct stones or with any stone >12mm on EUS
• Patients with no bile duct stones on EUS
• Patients with altered biliary anatomy (periampullary diverticulum, anomalous pancreatibiliary junction, altered surgical anatomy)
• Patients who are pregnant or breast-feeding
