I mentioned about an operation of Pancreatoduodenectomy (PD) which gave me a chance to take an interest in biliary tract diseases. PD trained me as a surgical specialist of biliary tract malignant diseases. I referred to our results of clinical treatment in carcinoma of the gallbladder and the extra-hepatic bile duct. And I also minutely mentioned my opinion about a carcinoma of the Papilla Vater in following items, 1) How do I diagnose the extension of the carcinoma. 2) Importance and usefulness of an intraoperative ultrasonography, and 3) angiography. 4) Relation of macroscopic morphological features and prognosis. 5) Prognostic factors. 6) Others. Survival rates of patients who had been treated by PD because of the carcinoma of the Papilla Vater was 56.6% at 5 years. And in the cases with lymph nodes involvement, 5 years survival rates after PD was 44.4%. 35 patients survived in 5 years after the operation, and 14 patients still survived 10 years after the PD.
