[Intrahepatic pressure, oxygen partial pressure and pain in chronic pancreatitis].

We investigated the relationship between pain, intraductal and parenchymal pancreatic pressures and oxygen partial pressure in 39 patients who underwent surgery for chronic pancreatitis with intractable pain. Acute pain was correlated with parenchymal pressure; correlation between pain and oxygen pressure could not be found. Since no strong correlation exists between pain and parenchymal pressure, we hypothesise that pressure and parenchymal factors contribute to the pathogenesis of pain in chronic pancreatitis.
