Studies on Cholecystopathy Chapter 3. Radiological Studies on Cholecystopathy in Hinase District, Okayama Prefecture

Cholangiographies were taken in 72 cases of cholecystopathy, and obtained the following results. 1. 95.8% of cases demonstrated radicopaque shadows of gall bladders and bile ducts. 2. Shadows of call stones were found in 6 cases (8.3%). 3. Dilatations of common bile duct were noted in 76.4% of the cases (8 mm in normal). The dilatations over 10 mm were seen in 38.9% of the cases. These dilatations were depend not only on agges but on clinical courses of the illness. 4. Cholecystograms were normal in 34 cases (52%). The dimensions of normal gall bladders were said to be less than 25 ㎠., and had few diagnostic value as they had rare relationships with other clinical changes. However, the contraction rate of gall bladder had less correlations with diameters of common bile ducts in rather younger people (before 40 years) in when common bile ducts were less than 10 mm in diameter. On the other hand, a correlation was noted in older generations who had somewhat wider common bile ducts. This suggested that many cholecystopathy patients began with "Dyskinesia" of the gall bladder initially. There had been some mutual relations between contraction rates of gall bladders and clinical pictures. 5. Some changes in gall bladders were observed in majority of 28 cases who had markedly dilated common bile ducts. According to the above, Maki's theory on dilatation of common bile duct due to organic changes in Papilla Vateri was not agreeable. 6. In cholangiographic studies no significant difference was seen in epidemiological distributions. 7. Studying the cholagiograms of cholecystopathy patients prevailing in Hinase District, Okayama Prefecture, a tendency was noted of marked dilatations of common bile ducts which was mainly not due to organic changes of Papilla Vateri but to clinical course and to organic changes of gall bladders. In view of cholangiographic findings the organic changes of gall bladders usually appeared after the age of 40 years.
