    Abstract:
    Chronic pancreatitis (CP) leads to deterioration of the endocrine pancreatic function by fibrotic destruction. The aim of the present study was to investigate whether resection or duct drainage in patients with CP would have a direct impact on the pancreatic beta cell function. An intravenous glucose tolerance test (IVGTT) was performed before, after and in some cases 3 months after operation in ten patients each of whom had been treated by either resection or duct drainage. Three patients undergoing pancreatic resection for cancer served as controls. Beta cell function was assessed by glucose elimination (K-values), insulin and C-peptide response. K-Values in patients with CP were not significantly influenced after resection (1.93 +/- 0.78/2.13 +/- 0.72; n.s.) or drainage (1.26 +/- 0.47/1.54 +/- 0.58; n.s.) but reduced in all three tumor patients (2.23 +/- 0.55/1.23 +/- 0.43). The initial insulin response [microU/ml] in CP patients was also not altered after resection (19.7 +/- 17.3/16.0 +/- 18.2; n.s.) or after drainage (16.7 +/- 16.5/13.0 +/- 9.0; n.s.), whereas all three resected tumor patients showed reduced values (42.9 +/- 15.7/17.5 +/- 3.8). Stimulated C-peptide synthesis [ngmin/ml] was not substantially lowered in patients resected for CP (90.5 +/- 85.6/73.8 +/- 48.9; n.s.) or in the drainage group (121.3 +/- 67.5/98.0 +/- 57.2; n.s.), but this parameter was decreased in every tumor patient postoperatively (157.8 +/- 66.9/125.1 +/- 69.6). Resection in patients with chronic pancreatitis did not inevitably result in loss of beta cell function. Parenchyma-preserving drainage procedures had no measurable advantage in this respect.(ABSTRACT TRUNCATED AT 250 WORDS)
