The clinical study on 101 cases of primary cancer of the extrahepatic biliary tract revealed the following conclusions:
1) Biliary tract cancer is not such rare disease as previously presumed.
2) Gallbladder cancer was more frequently found in females whereas biliary ductal cancer was more frequently found in males.
3) Regarding the age, the average was 51.2 years, and years of highest frequency was 50-59.
4) Because gallbladder cancer begins with the symptoms of acute or chronic cholecystitis, the active surgical operation for acute and chronic cholecystitis can be the only answer for the early surgical treatment of gallbladder cancer, And when one finds chronic inflammatory thickening of the gallbladder during the course of abdominal surgery, then cholecystectomy should be performed and examine immediately for the Presence of tumor inside of gallbladder.
5) Of the biliary tract cancer, the nodular type and papillary adenocarcinoma proliferation into ductal lumen, the resection alone can be, in many cases, the radical treatment.
6) For cancer of ampulla of vater, whipple´s operation and ampullectomy can be regarded as radical treatment.
7) For the diffuse infiltrating and the type of massive infiltration into the porta hepatis, in biliary tract cancer, the by-pass procedure anastomosing jejunum and upper biliary tract, such as intrahepatic duct, can prolong the survival period and make the patient comfort while living.
8) The operative death of biliary tract cancer was 9.9% and the surviual period upto 6 months was 68%, 22% upto one to two years and over two years it was 10%.
9) The cases of gallstone accompanying the biliary tract cancer, in our series, were quite few and therefore we could not presume it as a causative factor.
