Background. The utility of repeat EUS in patients with suspicion for pancreatic cancer after non-diagnostic EUS-FNA study is not well established. Aim. Determine the accuracy of repeat EUS-FNA in patients with suspected pancreatic cancer and prior non-diagnostic EUS-FNA. Methods. Retrospective cohort study. Results. From 2002 to 2008 in our institution 28 patients underwent repeat EUS-FNA for s...

BACKGROUND Surgical treatment of hyperparathyroidism relies on the ability to accurately identify parathyroid tissue. The use of intraoperative fine-needle aspiration (FNA) with measurement of intact parathyroid hormone level (iPTH-FNA) has been suggested as a useful adjunct and is evaluated in this pilot study. METHODS An institutional review board-approved retrospective review was performed...

Background and study aims  Tumor seeding after endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is rare. A 53-year-old man underwent transesophageal EUS-FNA for diagnosis of a 6-cm mass in the mediastinum as seen by computed tomography (CT). Four weeks later, repeat CT scan revealed a mass in the esophageal wall. Upper gastrointestinal endoscopy confirmed a lesion in the mid-esopha...

cytogenetic approaches are used in systematic studies implying differences between species and variation between populations. in this study, morphology of chromosomes and chromosome number of 210 specimens of 23 rodent species from different localities of iran were investigated. specimens belong to five families comprising dipodidae (allactaga elater (2n=48, fna=92); a. williamsi (2n=48, fna=92...

Background and Objective: Transesophageal endoscopic ultrasound with bronchoscope-guided fine-needle aspiration (EUS-B-FNA) is a feasible well-tolerated modality that increasingly used to diagnose intrathoracic lesions. This narrative review summarizes the current application of EUS-B-FNA for diagnosing lung cancer, thoracic sarcoidosis, metastases from extrathoracic malignancies.

OBJECTIVE To determine the contribution of percutaneous cutting needle biopsy (PNB) subsequent to fine-needle aspiration (FNA) in the diagnosis of chest lesions. DESIGN A retrospective review of 220 patients who underwent CT-guided FNA followed immediately by PNB performed at our center between 1988 and 1995 was undertaken. Thirty-eight patients were excluded because FNA and/or PNB specimens ...

BACKGROUND EUS-guided FNA can help diagnose and differentiate between various pancreatic and other lesions.The aim of this study was to compare approaches among involved/relevant physicians to the controversies surrounding the use of FNA in EUS. METHODS A five-case survey was developed, piloted, and validated. It was collected from a total of 101 physicians, who were all either gastroenterolo...

INTRODUCTION Many surgeons use intraoperative frozen-section (FS) biopsy of thyroid nodules to predict malignant disease, but the findings are often not in agreement with those of fine-needle aspiration (FNA) biopsy. Our objective in this study was to assess the value of intraoperative FS biopsy in patients with nodular disease of the thyroid gland. METHODS In this study, 203 patients underwe...

Background. There is a high incidence of inconclusive cytopathology at initial EUS-FNA (endoscopic ultrasound-guided fine-needle aspiration) for suspected malignant pancreatic lesions. To obtain appropriate preoperative or palliative chemotherapy for pancreatic cancer, definitive cytopathology is often required. The utility of repeat EUS-FNA is not well established. Methods. A retrospective coh...

The fine needle aspiration (FNA) biopsies performed on thyroid nodules at Turku University Central Hospital from 1983 to 1988 were reviewed. Of the 1,054 total aspirated nodules, 194 were investigated histologically after thyroid surgery (191 cases) or at autopsy (3 cases). Two cases with an insufficient FNA sample, 4 with an incidental occult papillary carcinoma and 2 cases with carcinoma outs...
