We describe three cases of severe necrotizing pancreatitis, with Apache II
scores of 11, 17 and 22, respectively. There was no significant pancreatic
parenchymal perfusion in any of the three patients on contrast-enhanced com
puted tomography. All three patients were primarily treated with percutaneo
us drains and all three subsequently required open laparotomies. We do not
recommend percutaneous drainage as a definitive therapy for severe necrotiz
ing pancreatitis. (C) 1999 Blackwell Science Asia Pty Ltd.
