Abstract: Objective To explore the value of three-dimensional (3D) visualization technique combined with ultrasound (US) guided percutaneous transhepatic  one-step biliary fistulation lithotripsy for the treatment of complex hepatolithiasis. Methods Sixty-five patients with complex hepatolithiasis were collected, which were divided into 2 groups randomly: an observation group and a control group. 33 cases were the observation group (3D+US group), which were treated by 3D technique combined with US-guided percutaneous transhepatic  one-step biliary fistulation lithotripsy with rigid choledochoscope; and the other 32 cases were the control group (US group) which were treated by US. The surgery time, surgical bleeding loss, stone clearance rate, postoperative hospitalization time, postoperative complications of the two groups were compared and analyzed. Results The surgery time of the 3D+US group  (65.6±12.9 min vs 74.5±13.6 min, t=2.686, P=0.009)were shorter than that of the US group, which  the differences were statistically significant (P<0.05); but compared with two groups of surgical bleeding loss(22.2±5.4 ml  vs  25.7±10.2 ml,t =-1.748,P=0.085), clearance of stones (93.9%  vs  90.6%,χ2=0.251,P=0.616), postoperative hospitalization time(6.8±2.1d  vs 7.2±2.4d,t=0.751,P=0.456) and postoperative complications(9.1%  vs  12.5%, χ2=0.196 ,P=0.658), there were no statistical difference (P>0.05).  Conclusions 3D visualization combined with US-guided percutaneous transhepatic one-step biliary fistulation is a safe, minimally invasive and highly efficient method for the treatment of complex hepatolithiasis, which may have its potential application in clinical prospects.
