Brief summary
Three-dimensional (3D) printing has gained popularity in medicine over the last decade. Once 3D printers have become more affordable, the true strength of this technique has been recognized because of its ability to obtain anatomical models based on the unique characteristics of each patient. Liver resections are challenging operations because of the complex nature of the liver and venous anatomy within the liver, so 3D imaging is a promising new tool for surgical planning.
Interventions
DEVICE3D PRINTING
A 3D digital image reconstruction and a 3D printing model were performed in all patients with complex liver tumors.

Inclusion criteria
* Complex liver tumors (bilobar disease, infiltration of suprahepatic veins or requiring two-time resection or intrahepatic vascular reconstruction). * Preoperatively was performed, a CT scan and / or MRI of all patients were performed to document the tumor distribution, estimate remaining liver volume, and identify tumor-vessel relationships in order to know the intraoperative vascular anatomy.

| Measure | Time frame | Description |
|---|---|---|
| Surgical planing | 2 weeks | Number of Participants susceptible of complex liver surgery as assessed by 3D printing and 3D digital image reconstruction, change from the baseline to the surgical strategy |
Secondary
