Common Bile Duct Gall Stones
Conditions
Brief summary
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.
Interventions
PROCEDURECommon bile duct stone removal without fluoroscopy.
ERCP stone extraction technique without fluoroscopy involves: (1) catheter or catheter with wire access into the bile duct, (2) confirmation of biliary access with catheter aspiration of bile, (3) performance of endoscopic biliary sphincterotomy or balloon dilation to widen the bile duct opening to permit stone removal, (4) stone removal - number of stones seen on EUS should match the number removed.
