Abstract:
Objective:To study the efficacy of three-dimensional (3D) CT reconstruction combined with 3D color printing compared with traditional imaging technology in treatment of complex hepatobiliary calculi treated with laparoscopy and choledochoscopy.Methods:A retrospective study was conducted on 128 patients with complex hepatobiliary calculi who underwent hepatobiliary surgery at the Qingdao Chengyang People’s Hospital, Qingdao Municipal Hospital Affiliated to Qingdao University and Qingdao University Affiliated Hospital from January 2019 to December 2019. A comparison was made between patients who underwent three-dimensional CT reconstruction combined with 3D color printing (the study group, n=62) and the traditional imaging technology group (the control group, n=66) on operation time, intraoperative blood loss, liver blood flow occlusion time, stone clearance rate, postoperative complication rate, and recurrence of calculi after operation. Results:The study group was significantly better than the control group in operation time, intraoperative blood loss, porta hepatis occlusion time, hospital stay and treatment cost (all P<0.05). The stone clearance rate of the study group was 96.8% (60/62), which was significantly higher than that of the control group (86.4%, 57/66) ( P<0.05). The incidence of postoperative complications in the study group was 3.2% (2/62), which was significantly lower than that in the control group (18.2%, 12/66) ( P<0.05). There was no significant difference in the stone recurrence rate between the two groups (all P>0.05). Conclusion:Three-dimensional CT reconstruction combined with 3D color printing contributed significantly to the surgical treatment of complex intrahepatic bile duct stones as these imaging technologies significantly improved surgical accuracy, improved stone clearance and reduced postoperative complication rates, and reduced surgical treatment costs.
