Abstract
A hepatic cone-unit represents an anatomical unit dominated by a smaller Glissonean pedicle. Anatomical resection of a tumor located in an intersegmental plane is challenging, but could be achieved effectively by performing multiple cone-unit resection. We performed double cone-unit laparoscopic resection of hepatocellular carcinoma located on the intersegmental plane between segments 6a, b. The liver parenchyma covering the posterior Glissonean pedicle was divided along Rouviere's sulcus, the Glissonean branches of segments 6a, b were isolated and ligated, and indocyanine green (ICG) negative counterstaining was performed. The hepatic parenchyma was dissected along the demarcation line to identify the right hepatic vein and the double cone-unit resection was then completed with a negative surgical margin. Thus, double cone-unit laparoscopic hepatectomy with ICG negative counterstaining may be a feasible option for tumors located in an intersegmental plane.
