Hypotonic duodenography and endoscopic retrograde pancreatography were performed in 45 non-icteric patients with suggested pancreatic disease or long-standing upper gastrointestinal symptoms. The accuracy of each method in the diagnosis of pancreatic disease was compared. Hypotonic duodenography revealed pancreatitis in 48 per cent and ERP in 83 per cent of the cases. All 6 pancreatic tumours were detected at ERP and 3 at duodenography. The role of hypotonic duodenography and endoscopic retrograde pancreatography in the diagnosis of pancreatic disease is discussed.
