Ascitic fluid with more than 250 PMNs/mm3 defines neutrocytic ascites and SBP. Many cases of ascites fluid with more than 1000 PMNs/mm3 (and certainly >5000 PMNs/mm3) are associated with appendicitis or a perforated viscus with resulting bacterial peritonitis. Appropriate radiologic studies must be performed in such patients to rule out surgical causes of peritonitis.
