the fna (fine needle aspiration) procedure is simple, inexpensive, available and a safe method for the diagnosis of a neck mass. fna has numerous advantages over open surgical biopsies as an initial diagnostic tool; therefore we decided to compare the accuracy of this method with open biopsy. this retrospective as well as descriptive study comparing preoperative fna results with existing data i...

PURPOSE Thyroglobulin measurement in fine-needle aspiration washout fluid (FNA-Tg) is widely used for detection of lymph node metastasis (LNM) in patients with papillary thyroid cancer (PTC). Recent studies suggested that serum anti-thyroglobulin antibodies (TgAbs) could interfere with FNA-Tg. We evaluated whether TgAbs can affect FNA-Tg when diagnosing LNM in postoperative patients with PTC. ...

BACKGROUND The aim of this study is to perform a cost-effectiveness comparison between palpation-guided thyroid fine-needle aspiration biopsies (P-FNA) and ultrasound-guided thyroid FNA biopsies (USG-FNA). METHODS Each nodule was considered as a case. Diagnostic steps were history and physical examination, TSH measurement, Tc99m thyroid scintigraphy for nodules with a low TSH level, initial P...

Abstract Fine needle aspiration (FNA) biopsy of thyroid nodules is a safe, cost-effective, and accurate diagnostic method for detecting cancer. However, about 10% initial FNA samples from patients are non-diagnostic require repeated FNA, which delays the diagnosis appropriate care. On-site evaluation sample can be performed to filter out samples. Unfortunately, it involves time-consuming staini...

CONTEXT Endoscopic ultrasound-guided trucut biopsy (EUS TCB) has a lower yield than fine needle aspiration (FNA) in pancreatic masses but the additional use of TCB to FNA may improve the diagnostic accuracy over FNA alone. OBJECTIVE To compare the yield of EUS FNA alone or combined with EUS TCB for diagnosis of pancreatic masses. DESIGN Single center retrospective case control study conduct...

Introduction The role of EUS-guided FNA as a highly sensitive modality in the diagnosis of pancreatic adenocarcinoma is well documented. However, there is little published data on the role of EUS-FNA in diagnosing pancreatic neuroendocrine tumors (NETs). Objective The aim of this study is to compare the sensitivity of EUS-FNA to that of CT-FNA for diagnosing pancreatic NETs. Methods This is...
