Objective:To study the use of percutaneous transhepatic one-step biliary fistulation based on three-dimensional visualization technology (3D-PTOBF) in the treatment of complex hepatolithiasis.Methods:A retrospective analysis was conducted on 116 patients with complex hepatolithiasis treated in the First Affiliated Hospital of Guangzhou Medical University from January 2016 to December 2019. There were 56 patients in the 3D-PTOBF group (treated by 3D-PTOBF), and 60 patients in the traditional PTOBF group (received traditional PTOBF approach). The stone clearance rate, postoperative complication rate, intraoperative blood loss, hospitalization time, number of cholangioscopic treatment procedures and stone recurrence rate were compared between the two groups.Results:When compared with the traditional PTOBF group, the 3D-PTOBF group had significantly less procedures (1.43±0.71 vs. 2.07±1.22, P<0.05), and shorter hospital stay (4.6±2.3 d vs. 6.1±2.9 d, P<0.05). There were no significant differences in the immediate stone clearance, final stone clearance, postoperative complications and stone recurrence rates between the two groups (all P>0.05). Conclusion:3D-PTOBF was safe and feasible to treat complex hepatolithiasis. When compared with PTOBF, it had the advantages of shorter operation time and decreased hospital stay.

Objective To study the efficacy and safety of percutaneous transhepatic one-step biliary fistulation (PTOBF) with rigid cholangioscopic lithotripsy for treatment of complicated hepatolithiasis under the ultrasonic navigation technique.Methods In this retrospective study,PTOBF lithotripsy surgery was performed in 94 patients with hepatolithiasis under general anesthesia with tracheal intubation,and with percutaneous transhepatic puncture of targeted bile duct under ultrasonic navigation in The First Affiliated Hospital of Guangzhou Medical University.Biliary expanders were used along a guidewire to expand the sinus gradually until 14Fr to establish a fistulous channel.Lithotripsy was then performed through the channel by rigid cholangioscopy.The operation-related data were collected and analyzed,including puncture and fistula establishment success ratio,complication rate,intraoperative blood loss,residual and recurrence hepatolithiasis rates.Results 94 patients (total 122 patient-times) underwent PTOBF lithotripsy.There was no perioperative mortality.The overall puncture success rate was 100%,and the fistula/puncture rate was 97.5% (119/122).In 118 patients success was achieved in 2 time (96.7%).The complication rate was 9.6% (9/94).The average intraoperation blood loss were (24.9 ± 21.3)ml.The residual calculus rate after therapy was 13.8% (13/94).All patients were followed-up for a period that ranged between 18 and 30 months.The recurrence rate was 14.9% (14/94).Conclusions Ultrasonic navigation technique plays an important role in bile duct puncture,sinus expansion and rigid cholangioscopic lithotripsy for treatment of complicated hepatolithiasis.PTOBF lithotripsy is a safe and effective procedure,which provides a new way in mini-invasive treatment for hepatolithiasis.It is worth generalizing.
