Infectious complications currently account for 80% of deaths from acut
e pancreatitis. The aim of this study was to evaluate the necessity fo
r prophylactic antibiotics in patients with severe acute pancreatitis.
Twenty-three consecutive patients suffering from acute alcoholic panc
reatitis with computed tomography demonstrating two or more fluid coll
ections were randomly assigned to one of two groups receiving either n
onantibiotic treatment or prophylactic antibiotics (ceftazidime, amika
cine, and metronidazole for 10 days). Sepsis was always diagnosed by p
ositive cultures. Seven episodes of severe sepsis occurred (pancreatic
infection and septic shock) in the nonantibiotic group, and no infect
ion occurred in the prophylactic antibiotic group (p < 0.03). In concl
usion, the use of prophylactic antibiotics in severe alcoholic acute p
ancreatitis significantly reduces the incidence of severe infection.
