Abstract

PURPOSE:

Acute appendicitis is the most common emergency abdominal inflammation requiring operation in children. As an acute-phase protein, plasma fibrinogen always increases with inflammation or tissue necrosis. This had brought about the assumption that hyperfibrinogenemia in patients with appendicitis may have a predictive ability for the preoperative diagnosis of appendiceal. Aim of this retrospective study was to assess the diagnostic value of hyperfibrinogenemia as a preoperative laboratory marker for appendiceal perforation in children with acute appendicitis.

METHODS:

We screened 466 children (168 girls, 298 boys, mean age, 7.6 years) with histologically confirmed acute appendicitis who received laparoscopic or open appendectomy between January 2012 and April 2014 in a pediatric surgery department of an academic teaching hospital. A retrospective review of the medical records including appendiceal perforation rate and laboratory results was conducted.

RESULTS:

Mean plasma fibrinogen level of all patients was 4.89 g/L (SD 1.74 g/L, range 1.94-15 g/L, median 4.61 mg/dL). Children with appendiceal perforation had a mean fibrinogen level of 6.18 g/L (SD 1.83 g/L, range 3.02-15 g/L, median 5.79 g/L), which was significantly higher than those with non-perforated children (P = 0.0001). The specificity of hyperfibrinogenemia for appendiceal perforation was 0.82 in comparison with 0.25 for white blood count (WBC) and 0.34 for C-reactive protein (CRP). Sensitivity was 0.74 compared with 0.76 for WBC and 0.94 for CRP.

CONCLUSION:

Children with hyperfibrinogenemia and clinical symptoms of appendicitis may be regarded as a higher risk of appendiceal perforation than whose fibrinogen level is normal.
