ENDOSCOPIC RETROGRADE PANCREATIC PARENCHYMOGRAPHY (THE 2ND REPORT)

Abstract

Parenchymogram visualized by Endoscopic Retrograde Pancreatic Parenchymography (ERPP) and ERCP was studied. The results were as follows; 1) Thirty of 91 cases had a pancreatic disease such as pancreatic cancer, chronic pan-creatitis, agenesis of the dorsal pancreas and so on. In most cases, we could not easily dif-ferentiate pancreatic cancer from other pancreatic diseases by the parenchymogram alone. 2) Comparing the findings of the parenchymogram of pancreatic cancer with the his-topathological findings of the resected specimen of the same case, we found that we could not decide evidence of pancreatic cancer and extension of invasion of pancreatic cancer by the parenchymogram alone. 3) Concerning serum amylase after ERPP, there were almost no changes in cases with pancreatic diseases such as pancreatic cancer or chronic pancreatitis, while there were re-markable changes in a half of the cases without pancreatic diseases. 4) Reading of the branches of the pancreatic duct was very useful in the differential diagnosis of pancreatic diseases. Therefore, we pointed out the necessity of visualization of the branches of the pancretic duct in ERCP.
