| Popis: | Objective To determine the value of Gram's stain of cell blocks of peritoneal fluid for the diagnosis of bacterial peritonitis. Study design The results of Gram's stain of 12 cases of culture-positive, frank bacterial peritonitis (FBP) and 11 cases of culture-positive spontaneous bacterial peritonitis (SBP) were compared with 6 cases of culture-negative frank sterile peritonitis and 21 cases of culture-negative spontaneous sterile peritonitis. Results For both FBP and SBP, Gram's stain had low sensitivity (8% and 9%). Overall, the positive predictive value of Gram's stain for peritonitis was 33%. Hematoxylin-eosin (HE) was just as sensitive but had a positive predictive value of 100%. Conclusion In cell block material of peritoneal fluid, Gram's stain is of little value except to further characterize organisms seen on HE. |
