Diagnostic Accuracy of Ultrasonography-Guided Percutaneous Core Needle Biopsies of Pancreatic Lesions

Abstract

Objective This study evaluates the results and complications of ultrasound-guided percutaneous core needle biopsies for solid masses of the pancreas performed at our university hospital . Methods Between January 2009 and June 2013 A total of 60 biopsy procedures were performed in 53 patients (30 males, 23 females) and 11 specimens were benign and 45 specimens were malignant according to histopathologic results. Results Sensitivity was 84.9%, specificity was 100% and diagnostic accuracy was 85.7%. No complications were observed during or after biopsy procedures Conclusion This study shows that ultrasound-guided biopsy is a reliable, time- and cost-saving method with a very low complication rate, high diagnostic accuracy and sensitivity, but benign biopsy findings should not be used to exclude the presence of pancreatic malignancy and biopsy should be repeated if there is a high clinical suspicion of malignancy.

Pankreas Lezyonlarında Ultrasonografi Eşliğinde Perkütan Kor İğne Biyopsilerinin Tanısal Doğruluğu

Abstract

Amaç Bu çalışmada, üniversite hastanemizde pankreasın solid kitlelerine yönelik ultrason eşliğinde yapılan perkütan kor iğne biyopsilerinin sonuçları ve komplikasyonları değerlendirilmiştir. Yöntemler Ocak 2009 ve Haziran 2013 tarihleri arasında 53 hastaya (30 erkek, 23 kadın), toplam 60 biyopsi işlemi uygulanmış ve histopatolojik sonuçlara göre 11 örnek benign, 45 örnek malign olarak değerlendirilmiştir. Bulgular Duyarlılık %84,9, özgüllük %100 ve tanısal doğruluk %85,7 olarak sonuçlanmıştır. Biyopsi işlemleri sırasında veya sonrasında herhangi bir komplikasyon gözlenmemiştir Sonuç Bu çalışma, ultrason eşliğinde biyopsinin çok düşük komplikasyon oranı, yüksek tanısal doğruluğu ve duyarlılığı ile güvenilir, zaman ve maliyet tasarrufu sağlayan bir yöntem olduğunu, ancak benign biyopsi bulgularının pankreatik malignite varlığını dışlamak için kullanılmaması gerektiğini ve yüksek klinik malignite şüphesi varsa biyopsinin tekrarlanması gerektiğini göstermektedir.
