Fig 1.
A. Scheme of tumor location. When tumor was on the peritoneal-side, it was classified as T2p, and when tumor was on the hepatic-side, it was classified as T2h. In addition, it was classified as T2hwhen tumor was located in the transition between the peritoneal-side and hepatic-side. H, hepatic-side; P, peritoneal side. B. Range for lymph node dissection. Ce T, celiac trunk; CHA, common hepatic artery; PHA, proper hepatic artery; CD, CDN; PH, porta hepatis; HL, hepatoduodenal ligament; SP, superior pancreaticoduodenal; CH, common hepatic artery lymph nodes.

Features of lymph node metastasis in T2 and T3 gallbladder cancer.
A. In T2p, if cystic duct lymph node was negative, downstream lymph nodes were also negative status. B. In T2h, even if CDN was negative, downstream lymph nodes were not negative. C, D. Even if CDN was negative, downstream lymph nodes were not negative. P, peritoneal-side; H, hepatic-side; +, lymph node positive; -, lymph node negative.
