Endoscopic ultrasound for the evaluation of cystic neoplasia of the pancreas

Abstract

Although the exact prevalence of cystic pancreatic lesions is unknown, it is estimated to be around 1% of the general population based on large-scale observational imaging studies. Cystic pancreatic lesions are increasingly diagnosed due to the widespread use of cross-sectional imaging modalities like computed tomography and magnetic resonance imaging. Cystic lesions of the pancreas consist of pseudocysts, congenital cysts (sometimes called simple cysts) and cystic neoplasms, including serous cystadenomas, mucinous cystadenomas and cystadenocarcinomas, and intraductal papillary mucinous neoplasms. Endoscopic ultrasound provides real-time high-resolution images of cystic pancreatic lesions with morphological details. The combination of fine-needle aspiration cytology with the other recently available diagnostic markers has further increased its diagnostic accuracy.

Pankreasın kistik neoplazilerinde endoskopik ultrasonografi

Öz

Pankreas kistlerinin gerçek prevalansı bilinmemekle birlikte büyük hacimli genel popülasyonun incelenmesi çalışmalarında yaklaşık %1 olarak rapor edilmiştir. Bilgisayarlı tomografi ve manyetik rezonans gibi görüntüleme yöntemlerinin son zamanlarda yaygın kullanımıyla pankreas kistlerinin tanısında artış vardır. Pankreasın kistik lezyonları; psödokist, konjenital kistler ve seröz kist adenom, müsinöz kist adenom, müsinöz kist adenokanser ve intraduktal papiller müsinöz neoplazi gibi neoplastik kistlerinden oluşur. Endoskopik ultrasonografi pankreas kistlerinin morfolojik detayı hakkında eş zamanlı yüksek çözünürlüklü bilgi sağlar. Endoskopik ultrasonografiye ince iğne aspirasyonu sitolojisinin eklenmesiyle kistlerin tanısal doğruluğu artar.
