Abstract:
Objective To explore the application value of three dimensions(3D)visualization combined with ultrasound(US)in percutaneous transhepatic cholangial drainage(PTCD).Methods A retrospective analysis was conducted on clinical data from 44 PTCD procedures performed by our team between January 2020 and March 2025.Twenty-one cases before January 2023 underwent conventional US-guided PTCD(US group),while 23 subsequent cases received 3D visualization-assisted US-guided PTCD(3D+US group).Both groups had comparable baseline characteristics.For the3D+US group,preoperative upper abdominal CT(non-contrast+contrast-enhanced)data were imported into the open-source 3D software 3D Slicer 5.6.2 to reconstruct individualized 3D models for preoperative puncture planning.Outcomes including puncture success rate,procedure time,times of puncture,therapeutic efficacy,and complications were compared between the two groups.Results Compared with the US group,the 3D+US group required fewer puncture times(1/2/3 times:19/4/0 cases vs.10/9/2 cases,Z=-2.602,P=0.009)and shorter procedure time[(38.8±12.2)min vs.(56.6±14.8)min,t=-4.372,P=0.000].No significant differences were observed in puncture success rate[100.0%(23/23)vs.90.5%(19/21),P=0.222],therapeutic efficacy(markedly effective/effective/ineffective:13/9/1 cases vs.10/9/2 cases,Z=-0.688,P=0.492),or complication rate[8.7%(2/23)vs.19.0%(4/21),χ2=0.313,P=0.576].Conclusion 3D visualization combined with US guidance for PTCD is safe and effective,facilitating reduced procedure time and fewer puncture times.
