Perihilar Glissonian Approach for Anatomical Parenchymal Sparing Liver Resections: Technical Aspects: The Taping Game.

OBJECTIVE

To present technical details for central hepatectomy and right anterior and posterior sectionectomies using perihilar Glissonian approach for anatomical delineation and selective inflow occlusion.

BACKGROUND

Central tumors and those deeply located in the right liver may require extensive resections because of their proximity to major vascular structures. In such cases, anatomical more limited resections such as central hepatectomy or sectionectomies may provide an alternative to extensive surgery by assuring both parenchymal sparing and suitable oncologic resection.

METHODS

We present the global concept for performing a perihilar Glissonian approach and its application to each individual anatomical procedure. This includes detailed descriptions, illustrations, and videos demonstrating the technique.

RESULTS

This technique was applied since 1991 for anatomical parenchymal resections including central hepatectomy (resection of segments 4, 5, and 8), right anterior sectionectomy (resection of segments 5 and 8), and right posterior sectionectomy (resection of segments 6 and 7). The feasibility rate of the Glissonian approach was 88%.

CONCLUSIONS

Perihilar Glissonian approach is a safe and reproducible technique that enables anatomical parenchymal preserving liver resections for selected central and right-sided deeply located tumors.
