Abstract
The correlation between fibrous increase of pancreas and lesions in neighboring organs of the pancreas was studied on necropsy cases, during 1968 and 1970, and the following results were obtained.
1. The 149 cases having fibrous increase of pancreas were classified into 3 types ; 1) intralobar type, 2) interlobar type and 3) mixed type. Concerning the frequency of all ages, that of intralobar type correlated with ageing.
2. The correlations between fibrous increase of pancreas and lesions in each organ neighboring the pancreas were as follows ;
Lesion Type
cholelithiasis mixed type
suppurative peritonitis interlobar type
peritoneal carcinomatosis intralobar- and interlobar type
Regarding gartric ulcer and duodenal ulcer, the former was correlated with the in-terlobar type, and the latter with the intralobar- and interlobar type.
3. Regarding the relation between liver and fibrous increase of pancreas, the frequency of mixed type increased in fibrous increase of liver. The mixed type and interlobar type were frequently encountered. Eighty three per cent of liver cirrhosis appeared with fibrous increase of pancreas, 80% of fibrous increase of pancreas were of the interlobar type, and 20% of the intralobar type.
Conclusion : The causes of pancreatic injury were classified into the following 3 types ; 1 lesions in neighboring organs of pancreas, 2) systemic diseases, and 3) unknown causes including primary pancreatic injury. Secondary pancreatic injury accompanying lesions in neighoring organs of pancreas is stressed.
