ABSTRACT
Objectives: The aim of this study was to survey the prevalence of fascioliasis in slaughtered cattle in order to provide breeders with feedback which may prevent cattle fascioliasis, as well as human fascioliasis. Methods: The results of meat inspection and the information extracted from the Discriminative Data Base on Individual Livestock in Japan were analyzed statistically in 6,224 cattle slaughtered at the Tsuyama Abattoir during the fiscal year 2002. Results: The age-adjusted fascioliasis and cholangitis rates of all cattle were 2.0% and 7.2%, respectively. When analyzed by cattle breed, both rates were significantly higher in Japanese native cattle than in Holstein or Jersey (Chi-square test, p<0.01). The cattle raised in Okayama Prefecture, Tochigi Prefecture and Shimane Prefecture were significantly different from cattle raised in other prefectures in the age-adjusted fascioliasis and cholangitis rates. Conclusion: The age-adjusted fascioliasis and cholangitis rates of all cattle can be considered as nationwide rates for slaughtered cattle. The results of the comparisons suggest that cattle fascioliasis is related to feeding with rice straw and that the measures to prevent cattle fascioliasis might differ among prefectural governments.

During the 13-year period from 1979 Jan. to 1992 Apr., 93 patients with carcinomas of the biliary tract including the ampulla of Vater and the pancreas were surgically treated at Kumiai General Hospital in the northern Hida district of Gifu Prefecture. In these 93 patients, 31 were diagnosed as suffering from carcinomas of the extrahepatic bile duct; 19, gallbladder carcinomas; 5, carcinomas of the ampulla of Vater and 38, pancreatic carcinomas. But the majority of these patients were classified into the far-advanced stages in accordance with the Japanese stage classification. Resectability was 58.1% in carcinoma of the extrahepatic bile duct, 42.1% in gallbladder carcinoma, 100% in periampullary carcinoma and 31.5% in pancreatic carcinoma and their survival rates were discouragingly low. To improve the postoperative results, it should be advocated that early diagnosis and treatment are most important for biliary tract carcinoma of m and fm in pathological depth, gallbladder carcinoma of m and pm in depth and small pancreatic carcinoma smaller than 2 cm.
