[Pathogenesis and treatment of pancreatic pseudocyst and pancreatic fistula]

The functioning part of parenchyma, isolated from the organ and its duct system due to the presence of pancreatitis or injury is the source filling the pseudocyst cavity and the cause which supports the pancreatic fistula existence. Possibility of pancreatic pseudocyst simulation in experiment on dogs was proved. An experimental cyst cavity decompression was done with the help of the tunnel conducted via papilla between the cyst and the main duct.
