title: Pancreatic secretion after secretin and cholecystokinin stimulation in chronic alcoholics with and without cirrhosis.
abstract: We have studied the volume, protein concentration, total protein, and chymotrypsin and trypsin outputs in pure pancreatic juice (PPJ) following endoscopic cannulation of the pancreatic duct in 11 male and 2 female patients with advanced alcoholic cirrhosis (AC). Results were compared to those obtained from 21 nonalcoholic volunteers (NAV) and 26 chronic alcoholic (CA) patients without cirrhosis. Intravenous stimulation with secretin followed 10 min later by intravenous cholecystokinin-pancreozymin (CCK-PZ) resulted in highly significant increases in volumes during both phases of pancreatic stimulation in AC compared to NAV and CA. Protein concentration and total output during secretin stimulation was not different among the three groups. During CCK-PZ stimulation, CA exhibited a significant elevation in protein concentration and total output compared to NAV and AC. Although total chymotrypsin output was lower in secretin-stimulated CA than other groups, no other differences between the groups were observed in either of the hormone-stimulation phases. Marked elevations in trypsin output were observed in secretin-stimulated AC and in CCK-PZ-stimulated AC and CA. The high PPJ volume and the relatively low protein concentration observed in AC may effect a washout phenomenon resulting in a decreased tendency for ductal protein precipitation in these patients.
