Figure 2: Key steps of lymphadenectomy. (a) Post-16b1 (inter-aortocaval) lymph nodes sampling. (b) Clearance of station 13a (posterosuperior pancreatic) and 17a (anterosuperior pancreatic) lymph nodes. (c) Posterosuperior pancreaticoduodenal artery originating from the Gastroduodenal artery is visualized after clearance of 17a nodes. (d) Lymph nodes on the left side of the portal vein are then taken to the right side enbloc (marked with an asterisk) to complete the radical lymphadenectomy
