Hypotonic duodenography and secretin-CCK test in the diagnosis of pancreatic disease.

Sixty-five patients with possible pancreatic disease or long-lasting upper abdominal symptoms were examined by means of the secretin-CCK test and hypotonic duodenography. Both examinations were performed after one duodenal intubation. In patients with pancreatitis functional abnormalities were revealed in 85 per cent while the duodenography was abnormal in 43 per cent. In patients with carcinoma, 77 per cent had abnormal exocrine pancreas function and 70 per cent had abnormalities demonstrated at duodenography. The value of the two examinations for assessment of patients with upper abdominal symptoms and pancreatic disease is discussed.
