Resection Map -A 3D cartographic map to guide laparoscopic hepatectomies

A clinical case with an implementation of the Resection Map application from the ARIS*ER Project took place at Rikshospitalet in week 41. The intraoperative navigation solution is a new 3D visualization system to support hepatectomies: the "Resection Map".
This is a pragmatic solution to enhance laparoscopic liver resection accuracy and safety with an intuitive visualization of its critical inner structures. This system aims at improving the transfer of pre-operative liver planning information into the intra-operative surgical stage, both in laparoscopic and open approaches.
Suregeons Dr. Bjørn Ewin and Dr. Arne Rosseland took part in the clinical case together with Dr P.Lamata. The anatomical resection of the first case in Oslo was a success: Dr. Edwin was able to identify and make the correspondence between the structures in the Map (main portal and hepatic veins) and the structures in the patient.

The concept

The "Resection Map" is a 3D representation of the planned resection path through the liver showing the relevant structures and risk areas.

It is a smart visualization of the planning information built from CT image studies. More information about the Resection Map can be found at the ARIS*ER Project website. The first publication about the system can be found at Springer Link.
