Background:

Advanced gallbladder cancer often involves liver invasion.
Surgical resection is a primary treatment modality.
Identifying optimal liver resection strategies is crucial.

Purpose of the Study:

To evaluate the therapeutic value of resecting liver segments IV inferior and V.
To define indications for this specific liver resection in advanced gallbladder cancer.
To analyze outcomes based on clinicopathological factors.

Main Methods:

Retrospective study of 201 patients with advanced gallbladder cancer.
Systematic liver resection including segments IV inferior and V.
Clinicopathological analysis of liver invasion and metastasis.

Long-term outcome assessment based on resection procedure.

Main Results:

All primary tumors invaded at least the subserosa of the gallbladder wall.
Liver invasion and metastasis were key factors analyzed.
Outcomes varied depending on the specific liver resection technique employed.

Conclusions:

Resection of liver segments IV inferior and V may be beneficial.
This approach is suggested for patients with liver bed invasion < 20 mm depth.
Clinicopathological findings support this targeted liver resection strategy.
