OBJECTIVES To evaluate the ability of percutaneous, transthoracic fine-needle aspiration biopsy (FNAB) to correctly diagnose intrathoracic masses, to determine what complications were experienced and at what rate they occurred and to define more clearly the role of this technique in the surgical management of lung masses. DESIGN A chart review. SETTING Kingston General Hospital, Kingston, O...

Spontaneous or fine-needle aspiration (FNAB)-induced remission of primary hyperparathyroidism (PHPT) may occur, especially for cystic lesions. However, the disease generally relapses over a short time period. We present a case of PHPT due to an enlarged hyperfunctioning parathyroid that underwent long-term (almost 9 years) clinical and ultrasonographic remission after the disappearance of the l...

With the ready availability of good quality portable units, office-based ultrasound (US) is increasingly being utilized by endocrine surgeons in their daily practices, particularly in the management of thyroid patients. Ultrasound-guided fine needle aspiration biopsy (US-FNAB) of thyroid lesions is a useful interventional diagnostic technique which can be readily performed by endocrine surgeons...

HYPOTHESIS Clinical or cytologic factors predictive of malignancy can be identified and incorporated into a treatment algorithm for patients with a fine-needle aspiration biopsy (FNAB) specimen interpreted as "suspicious for" papillary thyroid cancer (PTC). DESIGN Retrospective review of a prospectively maintained database. SETTING University-affiliated tertiary care hospital. PATIENTS Se...

OBJECTIVE A crucial problem in the non-operative diagnosis of thyroid nodules is the significant amount of non-diagnostic biopsies. This is a challenge for practicing endocrinologists especially when the results of the repeated biopsies remain non-diagnostic. The lack of a concrete preoperative diagnosis may result in unnecessary thyroidectomies in patients. Alternatively, it may also lead to t...

BACKGROUND Fine-needle aspiration biopsy has become the standard of care for the evaluation of thyroid nodules. More recently, the use of ultrasound guided fine-needle aspiration biopsy (UG-FNAB) has improved adequacy of sampling. Now there has been improved access to UG-FNAB as ultrasound technology has become more accessible. Here we review the adequacy rate and learning curve of a single sur...

OBJECTIVE To evaluate the feasibility of genetic testing of uveal melanoma using fine-needle aspiration biopsy (FNAB). METHODS We reviewed the clinical records of all patients of the Ocular Oncology Service at Wills Eye Hospital with the diagnosis of uveal melanoma who underwent FNAB for genetic testing for chromosome 3 status between November 1, 2005, and March 1, 2006. The FNAB was performe...

Objective The aim of this study was to evaluate pain scores and specimen adequacy for ultrasound-guided fine-needle aspiration biopsy (US-FNAB) of thyroid nodules without and with local anesthesia (LA). Materials and methods The US-FNAB procedure was performed on 183 patients with and without LA. One puncture was made for solid nodules, and if patients could tolerate it, a two-puncture techni...

BACKGROUND AND OBJECTIVE Nodular thyroid disease is a common condition in our clinical practice, and fine needle aspiration biopsy (FNAB) is the diagnostic procedure of choice. Its main limitation is the number of non-diagnostic samples. Since the Bethesda criteria were implemented in 2007 (a consensus document on the morphologic criteria and diagnostic terminology for interpretation of thyroid...

INTRODUCTION The majority of thyroid fine needle aspiration biopsies (FNAB) today are performed in the office freehand by palpation. Not infrequently, patients are sent to radiology for an ultrasound-guided FNAB (USG-FNB). Real-time ultrasound (US) allows for continuous visualization of the needle during insertion and sampling. Historically, USG-FNAB has been a procedure performed by a radiolog...
