“Papillary Balloon Dilation Versus Intraductal Lithotripsy”
Our aim is to compare the efficacy, safety, procedural time required, and costs of a strategy initially employing cholangioscopy guided intraductal lithotripsy (laser/electrohydraulic lithtripsy (EHL)) versus a strategy initially using papillary dilation for removal of large bile duct stones.
Procedure - Initial therapy with papillary balloon dilation
patients will first undergo papillary dilation
Procedure - Initial therapy with intraductal lithotripsy
patients will first undergo intraductal laser or electrohydraulic lithrotripsy
Prospective Randomized Trial of Cholangioscopy Guided Intraductal Lithotripsy Versus Papillary Balloon Dilation for the Endoscopic Treatment of Large Bile Duct Stones
