Detailed Description

Project goal is to evaluate utility of personalized 3D printed models in preoperative planning and performing laparoscopic liver resections. Models will be developed with unique, low-cost approach. Project will consist of three overlapping modules/stages evaluating:

  1. Accuracy of 3D printed liver models compared to computed tomography and standard surface or volume rendering
  2. Whether 3D printed utilized in planning surgery affects the decision making regarding the surgical plan
  3. Whether 3D printed models utilized in planning and navigating laparoscopic resections affect perioperative outcomes

Methodology of developing 3D models is described elsewhere. Printed models will be delivered to surgical team at least 5 days prior to the resection. Surgery will be performed in both arms according to the department's procedures and surgical oncology guidelines.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: With 3D Model
Patients in this arm will undergo laparoscopic liver resection with prior planning utilizing both 3D printed model and computed tomography (or/and magnetic resonance imaging)
Procedure: Laparoscopic liver resection
Laparoscopic liver resection for oncological purposes
Device: 3D printing model
Use of 3D printed liver model in decision-making: preoperative planning and intraoperative guidance.
Active Comparator: Without 3D Model
Patients in this arm will undergo laparoscopic liver resection with prior planning utilizing only standard medical imaging computed tomography (or/and magnetic resonance imaging) without development of 3D printed model
Procedure: Laparoscopic liver resection
Laparoscopic liver resection for oncological purposes
