Summary

When lymph node dissection of stations 12 and 13 is performed, resecting the bile duct from the superior portion of the pancreas to the confluence of the right and left hepatic ducts allows complete removal of the station 12 and 13 lymph nodes. Preserving the bile duct from the superior pancreas to the hepatic confluence, however, makes a skeletonizing dissection of the duct impossible in order to safeguard the biliary blood supply, inevitably leaving behind a small amount of periductal lymphoid tissue. This results in incomplete lymph node clearance, which may increase the risk of postoperative recurrence and reduce the R0 resection rate.

This study aims to investigate the lymph node dissection approach for surgically resected cholangiocarcinoma following induction therapy, to establish criteria for evaluating surgical indications, and to provide a basis for surgical treatment strategies in patients with cholangiocarcinoma.
