Abstract
A manometer has been developed to permit measurement and control of the injection pressure of the contrast medium in endoscopic pancreatocholangiography (EPCG). Using this method we have retained the precision of the investigation but have avoided pancreatic damage caused by excessive pressure. The findings of pancreatic carcinoma in EPCG were characterized by stenosis and obstruction of the main pancreatic duct and, sometimes, by a peripheral filling defect. Obstructed type, stenosed type, pancreatic-field-defect type, and mixed type were encountered in that order of frequency. 28 of 29 proved cases of pancreatic carcinoma were correctly diagnosed preoperatively by EPCG. There were two possible false positive diagnoses. Chronic pancreatitis was classified into three groups: minimal, moderate, and advanced pancreatitis, according to a grading of findings in EPCG. The main findings of minimal and moderate pancreatitis were “pancreatectasis.” There was a close correlation between histological and EPCG grading of chronic pancreatitis. EPCG is now one of the most reliable procedures for the detection of diseases of the pancreatic and biliary systems.
