Abstract
Introduction
Acute appendicitis is one of the most common surgical emergencies worldwide. Clinical scoring system systems have been developed to diagnose acute appendicitis, but insufficient to predict the complication. The amount of serum biomarkers elevates in response to acute inflammation, which could be beneficial for diagnostic tools. Accordingly, a meta-analysis was conducted to evaluate the efficacy of platelet indices, including mean platelet volume (MVP) and platelet distribution width (PDW) as potential biomarkers for the diagnosis of a diagnosis of acute appendicitis.
Material and methods
The dataset was defined by searching for articles published until December 2020 from PubMed, EMBASE, Google Scholar and the Cochrane database. The meta-analysis was performed using Review Manager Software version 5.4.1.
Results
The final analysis was made from 9 studies, including 3124 patients. The results demonstrated that lower MPV values was significantly associated with acute appendicitis (odds ratio (OR) = 0.81, 95% confidence interval (CI) = −1.51 to −0.11, P = 0.02), but not associated with complicated appendicitis by comparing it with the control (OR = −0.13,95% CI = −0.33 to −0.07, P = 0.19) and non-complicated appendicitis groups (OR = −0.13,95% CI = −0.30 to −0.04, P = 0.14). The present study failed to demonstrate the diagnostic value of PDW for the prediction of appendicitis and its complication.
Conclusion
The results of the meta-analysis strongly indicate that a lower MVP values could function as a marker for predicting the acute appendicitis.
Platelet play an important role in the response to systemic inflammation and sepsis.
Inflammatory process activated platelets destruction consequence in the release of small platelets into bloodstream.
This studycompared the association between the platelet indices and the diagnosis of acute appendicitis.
Lower mean platelet volume(MVP) is a significant diagnostic marker for acute appendicitis.
