title: Antibiotic prophylaxis in severe acute pancreatitis.
abstract: Severe acute pancreatitis is considered to be a subgroup of acute pancreatitis with the development of local and/or systemic complications. A significant correlation exists between the development of pancreatic necrosis, the frequency of bacterial contamination of necrosis and the evolution of systemic complications. Bacterial infection and the extent of necrosis are determinants for the outcome of severe acute pancreatitis. The late course of necrotizing pancreatitis is determined by bacterial infection of pancreatic and peripancreatic necroses. Mortality increases from 5-25% in patients with sterile necrosis to 15-28% when infection has occurred. The use of prophylactic antibiotics has been recommended in patients with necrotizing pancreatitis. Several controlled clinical trials demonstrated a significant reduction in pancreatic infections or a significant reduction of hospital mortality. However, the results of these clinical trials are controversial and not convincing. Recently, the largest randomized placebo-controlled, double-blind trial has been able to demonstrate that antibiotic prophylaxis with ciprofloxacin and metronidazole has no beneficial effects with regard to the reduction of pancreatic infection and the decrease of hospital mortality. The clinical data from this placebo-controlled trial do not support antibiotic prophylaxis in all patients with necrotizing pancreatitis, but in specific subgroups of patients with pancreatic necrosis and a complicated course.
