Abstract

Amaç: Akut apandisit (AA) genel cerrahi pratiğinde
sık karşılaşılan bir durumdur. Ancak doğru tanıya ulaşmada bazen
zorluklar olabilmektedir. Bu çalışmanın amacı AA tanısında platelet
lenfosit oranının (PLO) belirleyiciliğini araştırmaktır.
Materyal ve
Metot: Akut apandisit tanısı ile ameliyat edilmiş 569 hastaya ait
hastane kayıtları geriye dönük olarak incelendi. Postoperatif
histopatolojik inceleme sonuçlarına göre hastalar iki gruba ayrıldı:
Akut apandisit grubu (G1) ve normal appendiks grubu (G2). Gruplar
arasında demografik analizler ve PLO hesaplamaları karşılaştırıldı.
Bulgular:
G1 de 475, G2 de 94 hasta vardı. AA tanısında PLO için sınır değer
136,5 (p=0,036) olarak hesaplandı. Duyarlılık ve seçicilik sırası ile
%56,3 ve %55,3 idi. Pozitif prediktif ve negatif prediktif değerler
sırası ile %86,2 ve %19,6 olarak bulundu.
Sonuç: AA tanısında ve tedavinin yönlendirilmesinde PLO değerli bir ölçüt olabilir.

Platelet to Lymphocyte Ratio and Acute Appendicitis

Abstract

Aim: Acute appendicitis (AA) is a frequent
condition for general surgery practice. However, sometimes there may be
difficulties in accurate diagnosis. The aim of this study is to research
the predictive value of platelet to lymphocyte ratio (PLR) in diagnosis
of AA.
Material and Method: Hospital records were investigated
retrospectively for 569 patients who underwent operation for AA
diagnosis. According to postoperative histopathological examination of
specimens, patients were divided into two groups: acute appendicitis
group (G1) and normal appendix group (G2). Demographic analyses and PLR
calculations on hospital admission were compared intergroup. Results:
There were 475 patients in G1 whereas 94 in G2. The cut-off value of PLR
for diagnosis of AA was 136.5 (p=0.036). The sensitivity and
specificity were 56.3% and 55.3% respectively. Positive predictive value
and negative predictive value were found as 86.2% and 19.6%
respectively.
Conclusion: PLR may be a valuable parameter supporting clinical evaluation for diagnosis and management of AA.
