説明

Staging of gallbladder cancer was attempted using an important prognostic factor “binf”, and the most appropriate basic forms of surgery was considered in 40 patients. On the basis of our new staging method, cases of gallbladder cancer were divided into the following four groups: group A with lesions restricted to within the gallbladder [binf0, hinf(-) ], group B with infiltration into the hepatic floor [binf0, hinf (+) ], group C with slight infiltration into the hepatic portal [binf11]and group D with severe infiltration into the hepatic portal [binf2,3]. According to this new classification, the percentages of patients treated by curative resection in these groups were 100 %,57 %,27 % and 0 %, respectively. The long-term results in terms of the 2-year survival rate differed significantly among these groups, with rates of 100 %,58.8 %,9.1 % and 0 %, respectively. Taking into account the curability and mode of recurrence related to each group, we believe that the basic forms of surgery indicated for these groups are as follows: group A, full-thickness cholecys+ R1 dissection; group B, subsegmental hepatectomy+R2-ex dissection; group C, extended right hepatic lobectomy pancreatoduodenectomy+portalresection+R3-ex, dissection; 3group D, en bloc resection of the hepatoduodenal ligament. This classification proved useful for obtaining the prognosis and for selecting the most appropriate basic surgical technique.
