Abstract

Investigations of pancreatic juice revealed new insights into the pathogenesis of chronic pancreatitis (cP). But many results are contradictory. In this paper pure human pancreatic juice from patients with cP (n = 14) was compared with results obtained from normal subjects (n = 22). The pancreatic juice was obtained endoscopically recording the absorption (280 nm) simultaneously. By means of this special technique 4 fractions could be exactly distinguished: 1. wash-out-period, 2. phase of secretin action, 3. phase of pancreozymin (CCK) action, and 4. post-CCK-phase. Total protein, trypsinogen, zinc sodium, and potassium were determined. In fraction 1 (wash-out-period) mean values of protein, trypsinogen and zinc are lower in patients with cP compared with control subjects. In case of zinc the difference is statistically significant. In fraction 2 (secretin-phase) no differences could be detected between cP and control subjects. In contrast in fraction 3 (CCK-phase) mean values of protein and trypsinogen are lower in control subjects than in patients with cP. But the standard deviations are so high that all differences are not statistically significant. The results indicate that under fasting conditions the pancreatic juice content of protein, trypsinogen and zinc is lower in patients with cP. But patients with cP can be stimulated much better with CCK than control subjects. Till now such a different behaviour during wash-out-period and CCK-stimulation is not reported in the literature.
