Spyglass single-operator cholangioscopy-guided laser lithotripsy for patients with difficult bile duct stones / 中华消化内镜杂志

ABSTRACT

Objective To evaluate the efficacy and safety of Spyglass single-operator cholangioscopy-guided laser lithotripsy for removing difficult bile duct stones.Methods A total of 39 patients with difficult bile duct stones were divided into Spyglass single-operator cholangioscopy-guided group (n =20) and fluoroscopy guided group (n =19) to receive corresponding treatments.The success rates of complete stone removal and the complication rates related to the procedure were compared between the two groups.Results There was no significant difference in success rate of complete stone removal between Spyglass single-operator cholangioscopy-guided group(17/20, 85.0％) and the fluoroscopy guided group(16/19, 84.2％ ,P =0.661) or in rates of procedure related complication (acute pancreatitis P =0.695, infection of bile duct P =1.000).Conclusion Both Spyglass single-operator cholangioscopy-guided laser lithotripsy and fluoroscopy are safe and effective.
