Right Liver Resections

Abstract

• Anatomical right liver resections include right hepatectomy (segments 5 to 8),right lobectomy (segments 4 to 8), right paramedian setorectomy (segments 5and 8), and right lateral sectorectomy (segments 6 and 7).

• Anatomical segment-oriented liver resections require accurate knowledge of landmarks and precise dissection of the hilar region. Appropriate surgical view, occasionally requiring associated laparotomy and thoracotomy, is crucial for a safe resection.

• Right liver mobilization (before or after parenchymal transection) is usually needed, and complete mobilization from the inferior vena cava is required if liver resection includes segment 1.

• After right hepatectomy or right lobectomy, fixation of the falciform ligament keeps the remnant liver in anatomical position and allows adequate outflow.
