For routine EUS-guided sampling of solid masses and lymph nodes (LNs) ESGE recommends 25G or 22G needles (high quality evidence, strong recommendation); fine needle aspiration (FNA) and fine needle biopsy (FNB) needles are equally recommended (high quality evidence, strong recommendation).When the primary aim of sampling is to obtain a core tissue specimen, ESGE suggests using 19G FNA or FNB ne...

UNLABELLED CT-guided fine-needle aspiration (FNA) of lung lesions is subject to sampling errors. The current study assessed whether information provided by (18)F-FDG PET/CT will decrease the false-negative (FN) rate and thus improve the accuracy of CT-guided FNA. METHODS Data from 311 consecutive patients with lung nodules who underwent (18)F-FDG PET/CT and CT-guided FNA within an interval of...

Fine-needle aspiration (FNA) is a well accepted initial approach in the management of thyroid lesions. It has come a long way since its introduction for nearly a century ago. In the Philippines, FNA of the thyroid was first introduced 30 years ago and has been utilized until now as a mainstay in the diagnosis of thyroid malignancy. The procedure is performed by pathologists, endocrinologists, s...

Introduction: Gastro-intestinal stromal tumors are mesenchymal tumors they have a unique immunophenotype, expressing c-KIT (CD117), DOG-1 and CD34 in most cases. Most commonly occurring in small intestine and stomach. Case report: We report a case of EUS guided FNA from gastric mass in a 60 year old patient. Cytology showed cellular smears with palisade of tumor cells and blunt end spindle cell...

background: the aim of this work was to study the feasibility of constructing a fast thorax model suitable for simulating lung motion due to respiration using only one ct dataset. materials and methods: for each of six patients with different thorax sizes, two sets of ct images were obtained in single-breath-hold inhale and exhale stages in the supine position. the ct images were then analyzed ...

Background: Different types of endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) techniques are used in clinical practice; the best method in terms of outcome is not standardized. Objectives: To compare diagnostic adequacy of aspirated material, cytopathologic and EUS morphological features among capillary action, suction, and no suction FNA methods. Methods: A prospective, single...

Background. Although it is possible to visualize gastrointestinal stromal tumors (GIST) of the stomach by endoscopy, their pretreatment histological diagnosis is often difficult. The aim of this study was to investigate predictors of accurate preoperative pathological diagnosis of gastric GIST. Material and Methods. We retrospectively studied patients with gastric GIST who had undergone pretrea...

We aimed to investigate the diagnostic accuracy of ultrasound (US)-guided fine-needle aspirates (FNAs) obtained from 854 consecutive Danish patients with a scintigraphically cold thyroid nodule in a borderline iodine-deficient area. Clinical, sonographic, and pathological findings in patients with a cold thyroid nodule undergoing US-guided FNA were prospectively registered. 408 patients underwe...

The objective of the current study was to assess the yield of endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA) for the diagnosis of sarcoidosis in a large patient group. Bronchoscopy with transbronchial lung biopsy (TBLB) is nondiagnostic in 30% of patients with suspected sarcoidosis and has a risk of pneumothorax and haemoptysis. In order to obtain a diagnosis, mediastinoscopy i...
