Platelet Lenfosit Oranı ve Akut Apandisit

Öz

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

Öz

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.
