Abstract

Background

The new cross-sectional radiological tools, 3D computed tomography and magnetic resonance, allow a precise study of the liver anatomy. Thanks to these imaging techniques, a new space inside the liver parenchyma, the “hepatic core,” was recently recognized, where the hila of liver segments are present.

Methods

On the basis of anatomical and radiological observations, we identified a new virtual plane of dissection, named “hepato-portal,” which is useful in liver segmentectomy, if integrated with the classical planes of dissection.

Results

Simulated surgical procedures can be intra-operatively transferred by ultrasounds. In this way, we performed ten “proper” liver segmentectomies through preliminary sections of the hilar vessels and a precise dissection of the boundaries of each segment.

Conclusions

Our experience underlines the value of integrating anatomy and radiology in the simulated liver surgery.
