Staging laparoscopy. Begin with a full inspection of the peritoneal cavity lifting the left and right liver to view the underside (A) and paying particular attention to the peritoneum (B). Use laparoscopic ultrasound to orientate on the origin of the left and right portal vein branches and carefully visualise the parenchyma of the right lobe (C). Look on the left side of the falciform ligament and scan segments II and III. Place the probe on the hepatoduodenal ligament in the transverse plane to examine the portal pedicle (E).
