Abstract
A comparison has been made between a modified Lundh test and the secretin-CCK test. Thirty-four patients with pancreatic disease (chronic pancreatitis, n=25; recurrent pancreatitis, n = 5; and pancreatic carcinoma, n = 4) and 20 patients with other gastrointestinal disorders were studied. The results showed that estimation of trypsin secretion, irrespective of the mode of stimulation, had a low sensitivity in detecting pancreatic disease. Estimation of bicarbonate secretion after secretin stimulation provided a more sensitive test, especially for disclosing chronic pancreatitis.
