Purpose:
Among the various types of biliary tract cancer, patients with single, small (<5 cm), peripheral intrahepatic cholangiocarcinoma (ICC), or small (<2 cm) gallbladder tumors (GBTs) rarely develop lymph node (LN) metastasis. We investigated a laparoscopic approach for hilar LN sampling in such cases.
Methods:
Among the 176 patients with biliary tract cancer who were treated from January 2012 to March 2017, 21 (ICC, n=4; GBT, n=17) met the above indications.
Results:
All patients were treated by a laparoscopic approach with R0 resection. After determining the pathologic diagnosis, 9 patients with GBT and all 4 patients with ICC underwent laparoscopic LN sampling; the mean numbers of sampled LNs were 2.6 and 7.3, respectively; no patients had metastasis. The mean operating times for GBT and ICC were 223 and 379 minutes, respectively; the mean blood loss was 23 mL and 171 mL. With the exception of 1 patient who developed intrahepatic metastasis of ICC at the opposite liver lobe, all of the patients were recurrence free.
Conclusions:
A laparoscopic approach could be safely applied under our indications.

01:23Detailed Structure and Function of Lymph Nodes
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
