Abstract:
Objective To investigate the techniques,safety,and efficacy of intraoperative holmium laser lithotripsy under cholangioscopic visualization for refractory intrahepatic stones. Methods A total of 38 patients with refractory hepatolithiasis underwent cholangioscopic holmium laser lithotripsy.The laser setting was: the wavelength of 2.1 ?m,the maximum mean output power of 100 W,the pulse peak power of up to 6 kW,and the laser fiber of 400 ?m in diameter.Results The stones were entirely removed on one session in all the 38 patients.The lithotripsy time was 3~5 min,the times of fragmentation was 3~8,and a total of 65 stones were fragmented.No bile duct injuries or biliary leakage happened.Cholangiography and B-ultrasonography at 2 postoperative months found no residual stones.Follow-up for 6 months found no recurrence.Conclusions Application of holmium laser lithotripsy under cholangioscopic visualization for the management of refractory intrahepatic stones is safe and effective.
