Fluoroscopy guided laser lithotripsy for difficult bile duct stones / 中华消化内镜杂志

ABSTRACT

Objective To evaluate the efficacy and safety of fluoroscopy guided frequency-doubled double-pulsed laser lithotripsy for removing difficult bile duct stones. Methods From March 2008 to December 2009, patients with difficult bile duct stones were divided into cholangioscopy guided group ( n = 21 )and fluoroscopy guided group ( n = 19) to receive corresponding treatments. The success rate of complete stone removal and the complication rate related to the procedure were compared between the two groups.Results There are no significant differences between 2 groups in regarding of either success rate of complete stone removal ( 19/21, 90. 5% in cholangioscopy guided group vs. 17/19, 89. 5% in fluoroscopy guided group, P ＞0. 05 ) or rate of procedure related complication (4/21, 19. 0% in cholangioscopy guided group vs. 3/19, 15. 8% in fluoroscopic guided group, P = 0. 559 ). Conclusion Frequency-doubled doublepulsed laser lithotripsy guided by cholangioscopy or fluoroscopy are both safe and effective.
