  • Title: Parotid salivary gland function in patients with exocrine pancreatic insufficiency.
    Author: McColl KE, Brodie MJ, Whitesmith R, Gray KF, Thomson TJ.
    Journal: Acta Hepatogastroenterol (Stuttg); 1979 Oct; 26(5):407-12. PubMed ID: 525218.
    Abstract:
    Parotid function tests were performed on 12 patients with pancreatic insufficiency due to chronic pancreatitis. The concentrations of sodium and bicarbonate in stimulated parotid juice were reduced compared to controls (p less than 0.001). The secretion of 75Se-selenomethionine by the parotid salivary gland and exocrine pancreas following a Lundh test meal was measured in 12 patients with normal pancreatic function and 16 patients with exocrine pancreatic insufficiency. Eight of these patients had chronic pancreatitis both parotid and pancreatic secretion of the isotope were impaired. In pancreatic carcinoma the pancreatic excretion was impaired with no significant impairment of parotid secretion. The combined pancreatic/parotid radio-selenium test may be useful in differentiating between chronic pancreatitis and pancreatic carcinoma as the cause of pancreatic insufficiency.
