A comparison of the accuracy of Tzanakis and Alvarado Score in the diagnosis of acute appendicitis: A systematic review and meta-analysis
Background and objectives
Acute appendicitis is one of the most commonly encountered surgical emergencies on a global level. Due to the requirement of an immediate clinical diagnosis and the presence of limited resources, clinicians and diagnosticians refer to scoring systems to diagnose this condition, among which Alvarado and Tzanakis scoring systems are widely used. This meta-analysis aims to compare the diagnostic accuracy of these two systems.
Methods
We searched PubMed, Google Scholar, and SCOPUS databases. All studies that reported diagnostic parameters of Alvarado and Tzanakis scores in patients with suspected acute appendicitis were selected. Diagnostic values such as sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and diagnostic accuracy were extracted from the selected studies and statistical analysis was performed with Meta Disc 1.4 software. Quality assessment of the selected studies was performed using the QUADAS-2 and QUADAS-C tools. Fourteen studies were included in our meta-analysis which enrolled 2235 patients.
Results
The overall sensitivity of the Tzanakis score was calculated as 0.86 (95% CI; 0.84-00.87) while the specificity was 0.73 (95% CI; 0.69–0.78). In addition, the area under the curve (AUC) was 0.9261 (SE; 0.0169) and the diagnostic Odds Ratio (OR) was 22.52 (95% CI; 9.47–53.56). The pooled sensitivity of Alvarado score was 0.67 (95% CI; 0.65–0.69) and the specificity was 0.74 (95% CI; 0.69–0.79). Moreover, the area under the curve (AUC) of the Alvarado score was 0.7389 (SE; 0.0489) and the diagnostic Odds Ratio was 4.92 (95% CI; 2.48–9.75).
Interpretation and conclusion
The Tzanakis scoring system has a higher sensitivity, area under the curve, and diagnostic odds ratio when compared to the Alvarado score. However, the Alvarado score has a marginally better specificity making it more reliable in excluding acute appendicitis.
期刊介绍：
Since its establishment in 2003, The Surgeon has established itself as one of the leading multidisciplinary surgical titles, both in print and online. The Surgeon is published for the worldwide surgical and dental communities. The goal of the Journal is to achieve wider national and international recognition, through a commitment to excellence in original research. In addition, both Colleges see the Journal as an important educational service, and consequently there is a particular focus on post-graduate development. Much of our educational role will continue to be achieved through publishing expanded review articles by leaders in their field.
Articles in related areas to surgery and dentistry, such as healthcare management and education, are also welcomed. We aim to educate, entertain, give insight into new surgical techniques and technology, and provide a forum for debate and discussion.
