Best evidence topic: Can acute appendicitis manifest with normal inflammatory markers?

Abstract

A best evidence topic has been constructed using a described protocol. The three-part question addressed was: for patients with suspected acute appendicitis can normal inflammatory markers rule out the diagnosis? Altogether 151 papers were found using the search strategy reported below. Seven were identified to provide the best evidence to answer the question. The author, journal, date, and country of publication, patient group studied, study type, relevant outcomes, results, and study weaknesses were tabulated. In conclusion, six out of seven papers are more in favour with the concept that normal inflammatory markers cannot effectively rule out the diagnosis of acute appendicitis.
