[Experimental acute necrotico-hemorrhagic pancreatitis in dogs. Treatment by intraductal block].

The aim of this experimental study was to demonstrate that the mortality of calcium chlorine induced acute pancreatitis in the dog was decreased by the intraductal injection of solid substances. Seventy-two dogs were used. In the control group (n = 5) the mortality was 100%. Three different drugs were used for the intraductal injection: Ethibloc (n = 37), Tissucol (n = 10) and silicones (n = 10). The mortality rate has been respectively of 13.5, 10 and 10%. In order to define at which level of the pancreatic duct the obstruction had a maximum efficiency, 10 dogs underwent a distal ligation of the pancreatic duct after induction of the pancreatitis. The mortality rate in this group was 100%. It can be therefore concluded that only the complete obstruction of the pancreatic duct decreases the mortality rate in this experimental model.
