Pancreas Splanchnic and Pancreatic Tissue Perfusion in Experimental Acute Pancreatitis
2002
Background: Gut hypoperfusion has a major role in the pathogenesis of multiple organ failure, which is the main cause of death in severe acute pancreatitis. The effects of experimental acute pancreatitis on splanchnic and pancreatic perfusion and oxygenation were studied to find out whether gut hypoperfusion occurs already at the same time as changes in pancreatic perfusion. Methods: Twenty-four domestic pigs weighing 21-27 kg were randomized to severe or mild acute pancreatitis or control groups. Eight anaesthetized and mechanically ventilated pigs were intraductally infused with taurocholic acid to induce severe acute pancreatitis and eight received intraductal saline to induce mild acute pancreatitis. Eight pigs served as controls. Results: Intraductally infused taurocholic acid rapidly induced severe necrotizing acute pancreatitis as assessed macroscopically and histologically. Histological changes of mild acute pancreatitis were seen in animals after intraductal saline infusion. After the induction, ...
