title: Angiography in chronic pancreatitis and pancreatic cancer. A critical evaluation.
abstract: A critical "blind" evaluation of 129 randomly selected angiographic examinations was carried out including 37 control patients, 58 patients affected by proven chronic relapsing pancreatitis and 34 patients with cancer of the pancreas. In 48.5% of the control patients a completely normal angiographic picture was found. The false positives were found in 10.8% of chronic pancreatitis and in pancreatic carcinoma in 5.5% of the cases. Equivocal signs were found in 35.2%. The percentage of the false negative results in chronic pancreatitis was 34.4% (of which 8.6% were suggestive of pancreatic cancer). In pancreatic cancer positive results were seen in 70.6% of the cases. The percentage of the false negatives was 26.5% (suggestive of chronic pancreatitis); equivocal signs were found in 2.9% of these patients. Notwithstanding the not-negligible percentage of errors, angiography can be usefully employed in diagnosis of pancreatic disorders.
