Primary carcinoma of the gallbladder and the extrahepatic bile duct.

The clinical records of 68 patients with primary carcinoma of the gallbladder (39 cases) and the extrahepatic biliary tracts (29 cases) were comparatively reviewed. The survivals with carcinoma of the gallbladder were limited to five patients operated upon because of cholelithiasis and/or cholecystitis. The majority of the cases preoperatively diagnosed as cancer of the gallbladder were not able to undergo radical cholecystectomy. Of seven patients with radically resected tumors among 29 cases with carcinoma of the extrahepatic biliary tracts, only two patients survived and other five died with locally recurrent tumors. This experience reemphasizes the inadequacy of the present diagnosing approaches to the diseases. Therefore, for discovery of the early cases with primary carcinoma of the gallbladder and the extrahepatic biliary tracts, it may be far more important to make more aggressive measures by using newly developed diagnosing tools.
