Amaç: Literatürde kolanjiokarsinomun CC endosonografik EUS özellikleri açık bir şekilde tanımlanmamıştır. Çalışmamızın amacı, CC'nin EUS özelliklerini belirlemek ve bunları bilgisayarlı tomografi BT ve endoskopik retrograd kolanjiyografi ERCP bulgularıyla karşılaştırmaktır.Gereç ve Yöntemler: Çalışmaya Ocak 2008-Ocak 2011 tarihleri arasında KK tanısı konan 35 hasta alındı. EUS, BT ve ERCP bulguları retrospektif olarak değerlendirildi.Bulgular: EUS, 33 % 95 hastada hipoekoik kitle lezyonu gösterdi. BT ve ERCP bulguları, tümörün lokalizasyonu açısından EUS bulguları ile uyumluydu. Kitle lezyonlarının kenar ve konturları 15 hastada düzenli ve iyi tanımlanmış, ancak 20 hastada düzensiz ve kötü tanımlanmıştır. Bu özellikleri göz önünde bulundurarak, EUS üzerinde 2 adet CC paterni belirledik: 1 safra kanalları ile net bir ilişkisi olmayan, düzensiz ve kötü sınır ile tanımlı hipoekoik bir lezyon 2 safra kanalları ile ilişkisi açıkça görülen, düzenli ve iyi bir sınır ile tanımlı hipoekoik bir lezyon.Sonuç: Bu retrospektif çalışmada EUS, CC'li tüm hastalarda kitle lezyonlarını ortaya koydu. CC, EUS üzerinde iki ayrı paten sergileyebilir

Endosonographic Features of Cholangiocarcinoma and Comparison with Computed Tomography and Endoscopic Retrograde Cholangiography Findings

Öz

Objective: Endosonographic EUS features of cholangiocarcinoma CC have not been clearly described in the literature. The aim of our study was to determine the EUS features of CC and to compare them to computed tomography CT and endoscopic retrograde cholangiography ERCP findings.Material and Methods: Thirty-five patients who were diagnosed with CC between January 2008 and January 2011 were recruited in the study. Their EUS, CT, and ERCP findings were retrospectively evaluated. Results: EUS showed a hypoechoic mass lesion in 33 95% patients. CT and ERCP findings were concordant with EUS findings in terms of localization of the tumor. The margin and contour of the mass lesions were regular and well defined in 15 patients; however, they were irregular and ill defined in 20. Considering these features, we identified 2 patterns of CC on EUS: 1 a hypoechoic lesion with an irregular and ill-defined border without a clear relationship with the bile ducts and 2 a hypoechoic lesion with a regular and well-defined border, with the relationship to the bile ducts clearly demonstrated.Conclusion: In this retrospective study, EUS revealed mass lesions in all the patients with CC. CC may exhibit two distinct patterns on EUS
