Efficacy and safety of SpyGlass guided laser lithotripsy for large bile duct stones / 中华消化内镜杂志

ABSTRACT

Objective To explore the value of SpyGlass (direct visualization system) guided laser lithotripsy for large bile duct stones in ERCP.Methods Thirty-three patients with large bile duct stones were randomly assigned to two groups SpyGlass guided laser lithotripsy group (n =16) and mechanical lithotripsy group (n =17).All patients underwent ERCP procedures for stones extraction.The success rate of complete stone removal, the early complication rate related to the procedure and procedure time were compared between the two groups.Results The success rate of complete stone removal in SpyGlass guided laser lithotripsy group was higher than that of the mechanical lithotripsy group [75.0％ (12/16) VS 41.2％ (7/17) ,P ＜ 0.05].There were no significant differences between two groups in either procedure time [(51.6 ± 18.6) min VS (60.4 ± 12.3) min, P ＞ 0.05] or the early complication rate related to the procedure (18.8％ VS 5.9％ ,P ＞ 0.05).Conclusion SpyGlass guided laser lithotripsy is safe and effective for large bile duct stones.
