TUMOR, CREST
The patient was positioned in a lateral position on a bean bag to open the angle between the ribs and the iliac crest. A three-port channel was used as the working triangulation unit with a camera in the center. The colon was mobilized by cutting its ligament. For right-sided GP, the right triangular ligament of the liver and posterior peritoneum were incised to fully expose the tumor and vena cava. The vena cava was carefully dissected to expose the adrenal vein and was controlled using a Hem-O-Lok. For left-sided GP, the lateral splenic ligaments were divided and the adrenal vein was gently controlled by dissection along the exposed left renal vein. Subsequently, the tumor was disassociated circumferentially, and nourishing vessels were sealed.
