Do hepatic-sided tumors require more extensive resection than peritoneal-sided tumors in patients with T2 gallbladder cancer? Results of a retrospective multicenter study

In peritoneal-sided T2 gallbladder cancer, radical cholecystectomy including lymph node dissection without liver resection is a reasonable operative option. Radical cholecystectomy including lymph node dissection with liver resection is suitable for hepatic-sided T2 gallbladder cancer.
