Abstract:
Hepatectomy is the primary treatment for hepatocellular carcinoma (HCC) and is categorized into anatomical hepatectomy and non-anatomical hepatectomy based on the extent of resection. Anatomical hepatectomy utilizes the portal territory (PT) liver segment or subsegment as the basic anatomical unit, systematically resecting the tumor-bearing PT and completely removing the Glisson system that supplies and demarcates this area to enhance oncological efficacy. Non-anatomical hepatectomy follows the principle of radical oncological resection, emphasizing the removal of liver tissue more than 1 cm away from the tumor margin. With the popularization of precision surgery concepts, minimally invasive anatomical hepatectomy based on PTs has been widely applied. However, the minimally invasive resection of segment S8 of the liver is still considered one of the most challenging liver resections. We successfully performed an anatomical resection of portal territory segment S8 of the liver using intraoperative ultrasound, fluorescent laparoscopy, and Lannaec membrane dissection techniques, achieving good short-term clinical outcomes.
