Our aim was to assess malignancy risk in adenomatoid nodules and suspicious follicular lesions of the thyroid obtained by fine needle aspiration (FNA) cytology. Retrospective research was performed of 276 patients who underwent thyroid surgery after preoperative ultrasound-guided FNA diagnosis of either adenomatoid nodule, cellular follicular lesion, "suspicious for follicular neoplasm" or foll...

PURPOSE Surgical resection as part of a multimodality approach in malignant pleural mesothelioma (MPM) has a high morbidity and mortality. Because mediastinal lymph node (MLN) metastases are a negative prognostic factor, preoperative staging is of paramount importance. Transesophageal endoscopic ultrasound with real-time guided fine needle aspiration (EUS-FNA) enables accurate MLN staging in lu...

BACKGROUND Transthoracic fine needle aspiration (FNA) cytology and core needle biopsy (CNB) are two commonly used approaches for the diagnosis of suspected neoplastic intrathoracic lesions. This study compared the diagnostic accuracy of FNA cytology and concurrent CNB in the evaluation of intrathoracic lesions. MATERIALS AND METHODS We studied FNA cytology and concurrent CNB specimens of 127 ...

INTRODUCTION Endoscopic biopsy techniques are useful in the diagnosis of sarcoidosis. There is a need for randomized trials to establish where these procedures fit in the diagnosis of sarcoidosis. OBJECTIVES The aim of the study was to compare the diagnostic yield of conventional transbronchial needle aspiration (TBNA) with endobronchial ultrasound-guided TBNA (EBUS-TBNA) and endoscopic ultra...

AIMS Fine needle aspiration (FNA) cytology is an accepted means of diagnosing and typing common forms of lymphoma, particularly small lymphocytic lymphoma, follicular lymphoma, and large B cell lymphoma. However, its usefulness for diagnosing less common forms of lymphoma is not clearly established and this study was designed to examine this. METHODS The study reviewed the FNAs of suspected l...

AIM To evaluate the diagnostic value and safety mainly regarding incidents of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) for pancreatic cystic lesions (PCLs). METHODS A total of 150 consecutive patients with suspected PCLs were prospectively enrolled from April 2015 to November 2016. We finally enrolled 140 patients undergoing EUS-FNA. We compared the diagnostic accuracy of...

BACKGROUND Fine needle aspiration biopsy (FNA) is a routine diagnostic technique for evaluating thyroid nodules. Many reports in adults consider that FNA is superior to thyroid ultrasonography (USG) and radionuclide scanning (RS). Only five studies have been published on FNA of childhood thyroid nodules. AIMS To investigate the reliability of FNA in the evaluation and management of thyroid no...

BACKGROUND : Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) of the pancreas has become the preferred method for tissue diagnosis for pancreatic solid masses. The yield of EUS-FNA in this setting is influenced by multiple factors. We hypothesized that general anesthesia (GA) may improve EUS-FNA yield by improving patient cooperation and stillness during the procedure. Our objectiv...

BACKGROUND/AIMS Although endoscopic ultrasound guided fine needle aspiration (EUS-FNA) has been introduced and its use has been increasing in Korea, there have not been many reports about its performance. The aim of this study was to assess the utility of EUS-FNA without on-site cytopathologist in establishing the diagnosis of solid pancreatic and peripancreatic masses from a single institution...

UNLABELLED Background and Aims. EUS-FNA is an accurate and safe technique to biopsy mediastinal lymph nodes. However, there are few data pertaining to the role of EUS-FNA to biopsy central lung masses. The aim of the study was to assess the diagnostic yield and safety of EUS-FNA of indeterminate central mediastinal lung masses. Methods. DESIGN Retrospective review of a prospectively maintaine...
