Diagnostic accuracy of hyperbilirubinaemia in anticipating appendicitis and its severity.

Background: Hyperbilirubinaemia is reported to be a positive predictor in diagnosing appendicitis and especially appendiceal perforation. We, therefore, analysed the diagnostic accuracy of serum bilirubin in anticipating appendicitis and its severity.

Methods: All consecutive patients undergoing appendectomy for suspected appendicitis from May 2009 to August 2011 were analysed.
