Excerpt
Although laparoscopic hepatectomy has become a standard approach in many specialized centers, anatomical resection of tumors located in the posterosuperior liver segments still poses technical challenges.
1,2 Laparoscopic, anatomical segment 8 (S8) resection was defined as a “technically major” resection in various, difficulty-scoring systems.
3,4 In addition, the multicenter, study results of the International Robotic and Laparoscopic Liver Resection Study Group indicate that laparoscopic, anatomical S8 hepatectomy is more difficult than anatomical S7 resection for several reasons.
5 First, anatomical S8 resection has multiple transection planes, including left-side, right-side, transverse, and dorsal. However, there are no anatomical landmarks that can guide transection at the boundary between S5 and S8. Second, the ramification pattern of portal veins in S8 differs between patients with some complex variations. …
