Accuracy and consistency of pancreatography

Pancreatography is a valuable diagnostic technic to identify structural changes in the pancreatic ductal system. Although specific diagnoses based on ductal changes are not always possible, patients with surgically normal glands and those showing changes of chronic pancreatitis were reliably identified in this series. Patients evaluated for postcholecystectomy pain usually had normal pancreatograms and grossly normal pancreatic glands at the time of surgical exploration. The overall consistency in interpretation of pancreatograms by experienced radiologists was approximately 80 per cent. Pancreatic cancer was poorly predicted due to either minimal changes in the ductal system or inability to distinguish gross changes from those seen with chronic pancreatitis.
