Standard and augmented secretin testing in chronic pancreatic alcoholic disease.

Sequential standard (1.0 U./kg.) and augmented (4.0-5.0 U./kg.) secretin response to the pancreas has been briefly compared in normal subjects and in patients with combinations of alcoholism, cirrhosis and alcoholic pancreatitis. The results of sequential testing led to the conclusion that, for clinical purposes, the standard test is adequate for the diagnosis of well established pancreatic pathologies causing gross destruction of the parenchyma. The augmented test is of particular value when the response to 1 U./kg. produced equivocal results, inasmuch as augmented stimulation enhances the masked secretory deficiency. The administration of the augmented stimulus to alcoholic patients yielded data which suggest a new hypothesis of pathogenesis for alcoholic pancreatitis, e.g., the postsecretin response pattern of minimal pancreatic inflammatory pathology is hypersecretion. Alcohol is thought to induce fatty degeneration of the pancreatic cell initially. Continued injury leads to necrosis and fibrosis.
