The detailed anatomical description of the liver described by Couinaud in 1954 is the basis for hepatic surgery. Surgical resection is the approach leading to the best survival rate in case of liver cancer. In hepatocarcinomas, systematic removal of the infected liver segment is considered the most effective technique to eliminate tumour, potential satellite nodules and avoid vascular spread. Resectability rate highly depends on the analysis of preoperative images. However, in 20% of cases, there are modifications compared with the initial surgical plan leading to an increase in morbidity rate.
In 2002, Couinaud highlighted the difficulty of identifying portal pedicles, especially because of anatomical variations, and recommended the use of a three-dimensional reconstruction from images provided by a helical scanner.
The hypothesis of the study is that 3D models would improve surgical planning leading to a decrease in intra-operative adjustments and mortality.
The aim of this multicentric, prospective study is to assess the benefit of 3D models in the surgical management of hepatocarcinomas, more specifically in the detailed analysis of 3D vascular structures and in the surgery planning with resection merges evaluation. The validation of this virtual method will be built on the comparison of the surgical plan based on the analysis of conventional preoperative images (CT-scan and MRI) and the surgical plan based on the analysis of 3D reconstruction.

Experimental: Surgical planning
Two surgical plans will be established preoperatively. The first plan will be based on standard preoperative images (CT-scan, MRI) review. The second plan will be based on the 3D model review.
Procedure: Surgical planning
Two surgical plans will be established preoperatively. The first plan will be based on standard preoperative images (CT-scan, MRI) review. The second plan will be based on the 3D model review. Both will be compared to the actual surgery performed in the operating room.
- Comparison of the intra-operative modifications rates [ Time Frame: At time of surgery ]Modifications in the surgical planning compared to the plan based on the analysis of standard preoperative images (CT-scan and MRI) and the plan based on the 3D model analysis: changes in surgical resection type (by specifying the surgical act: tumorectomy, segmentectomy, bi-segmentectomy or lobectomy…) or no surgery.
- Comparison of tumor(s) location [ Time Frame: At time of surgery ]Comparison of tumor(s) location based on 3D model and standard preoperative images analysis.
- Comparison of vascular network anatomy [ Time Frame: At time of surgery ]Comparison of vascular network anatomy based on 3D model and standard preoperative images analysis.
- Choice of surgical plan [ Time Frame: At time of surgery ]Surgery done according to a) surgical plan based on standard preoperative images analysis, b) surgical plan based on 3D model analysis or c) alternative approach (by specifying the surgical act: tumorectomy, segmentectomy, bi-segmentectomy or lobectomy….)
- Modification of the initial surgical plan, if applicable [ Time Frame: At time of surgery ]Description of perioperative events having modified the initial surgical plan.
- Comparison of resection merges [ Time Frame: At time of surgery ]Comparison of expected resection merges based on standard preoperative images and 3D model analysis and actual resection merge in the operating room.
- Comparison of resection volumes [ Time Frame: At time of surgery ]Comparison of expected resection volumes based on standard preoperative images and 3D model analysis and actual resection volume in the operating room.
- Comparison of surgical merge size [ Time Frame: At time of surgery ]Comparison of surgical merge size (mm) based on 3D model and standard preoperative images analysis.
- Morbidity [ Time Frame: At time of surgery and 3 months after surgery ]Morbidity specific to the procedure.
- Mortality [ Time Frame: At time of surgery and 3 months after surgery ]Mortality specific to the procedure.
- Preoperative images independent analysis [ Time Frame: 3 years ]Analysis of preoperative images (CT-scan/MRI and 3D model) by a senior team on one hand, and a junior team (surgeons + radiologists) on the other hand.
