A Comparison of Pancreatic Pseudocysts with True Pancreatic Cysts According to Endosonographic Criteria(A Six-Year Retrospective Analysis)

Abstract

27A AB BS S T TR RA AC CT T O Ob bj je ec ct ti iv ve e: : During the past years, endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA) has become an important tool in cyst therapy and tissue sampling. In this retrospective analysis, the primary objective was to determine the efficacy of EUS guided FNA for diagnosis of pancreatic pseudocysts (PP) and true cysts. The secondary aim was to evaluate the size and location of the cysts. M Ma at te er ri ia al l a an nd d M Me et th ho od ds s: : Eighty-three patients with pancreatic cysts and pseudocysts were retrospectively identified from the database of Gazi University Department of Gastroenterology. Size of the cysts and available data on fine needle aspiration and surgical aspiration were also recorded. R Re es su ul lt ts s: : According to EUS criteria, 48 patients (57.8%), 24 female and 24 male subjects with PP and 35 (42.2%) patients (24 female and 11 male) with cystic lesions (totally 83 patients, 48 female and 35 male) were enrolled in the study. The size of the cysts in the pseudocyst group was significantly greater than that of the simple cysts. There was no difference between the two groups in terms of patients age. There was also no difference between the two study groups in terms of location (p= 0.404). The most common location for both cysts was the head of the pancreas. Normal cytology was the most common finding among cytological results of fine needle aspiration in the both groups. Bacterial growth was detected in one sample and fungal culture was positive in another in the PP group. One of the samples showed atypical cells and another demonstrated mucinous cells in the same subgroup. There were 4 (11.4%) cases with mucinous cystic neoplasm and one case with cystadenocarcinoma in the true cyst group. C Co on nc cl lu us si io on n: : Cysts of the pancreas have some characteristic properties that can be differentiated with EUS guidance.

Yaptığımız bu retrospektif analizde EUS yolu ile ince iğne biyopsisinin pankreatik kist ve psödokistlerdeki tanısal etkinliği incelenmiştir. İkincil amaç olarak psödokistlerin ve gerçek kistlerin boyut ve lokalizasyon açısından farklılığı analiz edilmiştir.
