title: Bisubsegmental liver resection for gallbladder cancer.
abstract: OBJECTIVE
  The ultimate goal was to determine the therapeutic value and indications of resection of segment IV inferior and segment V in patients with advanced gallbladder cancer.
  
  
  METHODS
  Indications for systematic resection of the liver, particularly segment IV inferior and segment V as defined by Couinaud (1) or Healey (2), in patients with advanced gallbladder cancer, were examined in a total of 201 patients with advanced gallbladder cancer who underwent surgical resection were studied.
  
  
  RESULTS
  All primary tumors invaded the subserosa of the gallbladder wall or deeper. Liver invasion and liver metastasis were studied clinicopathologically, and the long-term outcome was analyzed according to the procedure used for liver resection.
  
  
  CONCLUSIONS
  The clinicopathological result suggests that resection of segment IV inferior and segment V of the liver may be beneficial in patients with liver bed type invasion less than 20 mm in depth.
