Laser Versus Mechanical Lithotripsy of Bile Duct Stones

Completed · Not applicable

Conditions studied: Choledocholithiasis

In brief

Very large bile duct stones are difficult to remove. The prefered method involves an endoscopic procedure known as endoscopic retrograde cholangiopancreatography (ERCP)performed using a special side viewing endoscope. In the past small baskets passed through the scope into the bile duct have been used to remove most stones using mechanical force. Recently very small scopes known as cholangioscope have been introduced through the side viewing endoscope directly into the bile duct. These cholangioscopes may be used to guide laser therapy of bile duct stones. The investigators suspect that stone destruction using cholangioscopy guided laser stone destruction may enable bile duct stones to be removed more quickly and safely when added to the mechanical techniques.
