Abstract
Carrying out the endoscopic pancreatic parenchymography in 369 subjects, it could be con-firmed that this method gave much clearer parenchymogramms easily and successfully except in subjects with severe chronic pancreatitis than the conventional ERCP, because a surface active agent (surfactant) was mixed with the contrast medium. With our method using Ang-iograf in as a contrast medium, the roentgenographic pattern that the fine branches of the pan-creatic duct were described in the homogeneous parenchym, could be obtained most frequently. Thus, its usefulness for detecting a minute lesion was approved. There was no serious accident during the examination. Hyperamylasemia which may be observed after the ERCP, if any, fell into the normal levels promptly because of the surface active agent. From these results, the usefulness and safety of the endoscopic pancreatic parenchymography could be confirmed clinically.
