Background: Appendicitis is a much studied about topic since the early years. Even with advances in imaging techniques, appendicitis still relies upon clinical examination as main resort of diagnosis. To aid this, several scoring systems have been developed taking into account various symptoms, signs and some basic laboratory investigations. Many studies done worldwide to check sensitivity spec...

INTRODUCTION The negative appendicectomy rate (NAR) is a quality metric in the management of appendicitis. While computed tomography (CT) has been associated with a low NAR, Alvarado scoring produces an acceptable NAR. The definition of negative appendicectomy may affect the NAR. This study examined the impact of CT, Alvarado score and definition on the NAR. METHODS The charts of 1,306 emerg...

BACKGROUND The Alvarado score can be used to stratify patients with symptoms of suspected appendicitis; the validity of the score in certain patient groups and at different cut points is still unclear. The aim of this study was to assess the discrimination (diagnostic accuracy) and calibration performance of the Alvarado score. METHODS A systematic search of validation studies in Medline, Emb...

INTRODUCTION Acute appendicitis is the most common abdominal emergency requiring emergency surgery. However, the diagnosis is often challenging and the decision to operate, observe or further work-up a patient is often unclear. The utility of clinical scoring systems (namely the Alvarado score), laboratory markers, and the development of novel markers in the diagnosis of appendicitis remains co...
