title: Acute appendicitis: proposal of a new comprehensive grading system based on clinical, imaging and laparoscopic findings.
abstract: Advances in the technology and improved access to imaging modalities such as Computed Tomography and laparoscopy have changed the contemporary diagnostic and management of acute appendicitis. Complicated appendicitis (phlegmon, abscess and/ or diffuse peritonitis), is now reliably distinguished from uncomplicated cases. Therefore, a new comprehensive grading system for acute appendicitis is necessary. The goal is review and update the laparoscopic grading system of acute appendicitis and to provide a new standardized classification system to allow more uniform patient stratification. During the last World Society of Emergency Surgery Congress in Israel (July, 2015), a panel involving Acute Appendicitis Experts and the author's discussed many current aspects about the acute appendicitis between then, it will be submitted a new comprehensive disease grading system. It was idealized based on three aspect of the disease (clinical and imaging presentation and laparoscopic findings). The new grading system may provide a standardized system to allow more uniform patient stratification for appendicitis research. In addition, may aid in determining optimal management according to grade. Lastly, what we want is to draw a multicenter observational study within the World Society of Emergency Surgery (WSES) based on this design.
