case_images: After the introduction of five trocars at the umbilical portion for the camera and at the subcostal area (Fig. 2), the left semi-decubitus position with the right side elevated approximately 20 degrees was applied.
case_images: Intraoperative findings. (A) The Glissonean pedicle of segment 7 (G7) was identified and divided. (B) The right hepatic vein was exposed to identify the venous branch of segment 7 (V7).
