Summary

This study aims to compare the overall rate of endoscopic clearance of complicated bile duct stones by Spyglass DS peroral cholangioscopy guided holmium:YAG laser/electrohydraulic lithotripsy versus conventional BML.

Conditions

  • Biliary Stones

Interventions

DEVICE

Spyglass DS cholangioscope

The 1.8Fr holmium:YAG laser fiber (Lumenis, Yokneam, Israel) will be inserted into the cholangioscope's working channel for lithotripsy under direct visualization. An EHL probe may alternatively be used depending on availability. Lithotripsy is applied until fragments of the targeted stone are no longer lumen filling, and can be dispersed easily with fluid irrigation. Fragmented stones are then removed by a combination of conventional techniques. To confirm stone clearance, the Spyglass DS cholangioscope will be re-introduced, and the bile duct will be examined for residual stones from the confluence of the right and left intrahepatic ducts to the papillary opening

DEVICE

BML

Biliary sphincterotomy with/without EPBD to the size of the lower bile duct with a limit of 15mm will be performed. Stones are removed by a combination of conventional BML, extraction balloon and/or baskets, without laser lithotripsy. An occlusion cholangiogram is performed to confirm stone clearance. In cases where stone clearance is incomplete, a plastic biliary stent bridging the stone will be inserted for temporary drainage until definitive management, usually within one month.
