  • Title: Polymorphonuclear count in ascitic fluid after laparotomy in cirrhotic patients.
    Author: Belghiti J, Panis Y, Chiche R, Faivre E, Fékété F.
    Journal: Hepatogastroenterology; 1992 Dec; 39(6):584-5. PubMed ID: 1483674.
    Abstract:
    In order to establish whether an ascitic polymorphonuclear count greater than 250/mm3 remains a diagnostic criterion for postoperative bacterial peritonitis, a prospective study of 16 patients with cirrhosis and ascites undergoing hepatectomy (n = 4), portocaval shunt (n = 5) and biliary and digestive surgery (n = 7) was carried out. Sixty-four consecutive specimens of ascitic fluid were obtained through abdominal one-way suction tubes left in situ. In 17 (26%) specimens, ascitic fluid was blood stained and the polymorphonuclear count was unreliable; none of these specimens demonstrated positive ascitic fluid culture. In the remaining 47 specimens the polymorphonuclear count ranged from 5 to 5,920/mm3. Positive ascitic fluid culture was significantly higher in polymorphonuclear > or = 250/mm3 group (5/13: 38%) than in polymorphonuclear < 250/mm3 group (2/34: 6%) (p < 0.02). These results suggest that, as in non-operated cirrhotic patients: (a) polymorphonuclear count should be taken in account in the diagnosis of postoperative bacterial peritonitis; (b) polymorphonuclear count greater than 250/mm3 is a good criterion for the diagnosis of bacterial postoperative peritonitis.
