Abstract

By using percutaneus transhepatic cholangiography and endoscopic pancreato-cholangiography, preoperatively we have diagnosed 59 cases of cancer of the pancreas and the biliary tract included 15 cases of cancer of the periampullary region.
In 11 out of 15 cases of cancer of the periampullary region, radical operation was performed, and other cases refused to have it.
We have investigated on the clinical courses, the diagnostic value of X-ray examination, PTC and ERCP, and otherwise the prognosis of the periampullary cancer.
We might conclude that PTC and ERCP were most useful examinations for the diagnosis of biliary diseases. Because, the end of common bile duct which dilated in high grade showed characteristically the feature of “U” type obstruction with pressure marks.
The prognosis of these cases was discussed retrospectively from the view points of macroscopic type and size of the tumor, metastasis to the local lymphnodes, the infiltration of vessels in these lesions at the time of operation, and the term from the onset of symptomes to operation.
