Three-dimensional visualization technology in one-stage establishment of a percutaneous transhepatic biliary tract in treatment of complex hepatolithiasis / 中华肝胆外科杂志

ABSTRACT

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.
