Pressure of papillary sphincter zone and pancreatic main duct in patients with alcoholic and idiopathic chronic pancreatitis.
To determine the significance of manometric pressure of the pancreatic duct in patients with alcoholic and idiopathic chronic pancreatitis, we used a microtransducer inserted through a duodenoscope to measure pressures in the papillary sphincter zone and pancreatic main duct in 20 control subjects and 31 patients with chronic pancreatitis without papillary stenosis including 10 cases of alcoholic chronic pancreatitis (ALCP) and 21 cases of idiopathic chronic pancreatitis (ICP). The pancreatic main ductal pressure was significantly higher in the patients with ALCP (55.7 +/- 28.9 mm Hg) or ICP (44.5 +/- 25.8 mm Hg) than in the controls (16.2 +/- 8.7 mm Hg), but there was no significant difference between ALCP and ICP. There was no significant difference between control subjects and ICP in the motility of the sphincter of Oddi. In ICP there were no correlationships between pancreatic ductal pressure and the motility of papillary sphincter zone. In ALCP, the frequency of the papillary sphincter waves was significantly higher than in normal subjects and there was a correlation between the pancreatic ductal pressure and the motility of the papillary sphincter zone. These data suggest that increased pancreatic ductal pressure in ALCP may be in part due to papillary dysfunction, but not in ICP.
