Summary

In a non-anatomical resection of a liver tumor, only the part of the liver with the tumor and a safety margin of 5 - 10 mm are resected. This is done to ensure a negative resection margin, which means that no tumor cells are at the boundary of the resection. These non-anatomical resections can be performed repeatedly in case of recurrence. However, compared to anatomical resections, it is more challenging to keep a negative resection margin as anatomical landmarks cannot be used for intra-operative guidance.

In this study, the investigators aim to clinically evaluate a 3d navigation system, where navigated intra-operative ultrasound data is used to create a virtual model and a surgical plan.
