In a prospective study pleural biopsy specimens obtained with a Tru-cut needle were compared with those obtained with an Abrams pleural biopsy punch from 36 patients in Zimbabwe judged to have an effusion of at least 1.5 litres; one patient had two biopsies. Both instruments were used on each patient, the Abrams punch being followed by the Tru-cut needle. There were no serious complications. Th...

Advances in optical imaging modalities, such as optical coherence tomography (OCT), enable us to observe tissue microstructure at high resolution and in real time. Currently, core-needle biopsies are guided by external imaging modalities such as ultrasound imaging and x-ray computed tomography (CT) for breast and lung masses, respectively. These image-guided procedures are frequently limited by...

PURPOSE To investigate whether the use of a disposable needle guide results in a decreased incidence of infectious complication after transrectal prostate needle biopsy (TPNB). MATERIALS AND METHODS Fifty five patients who underwent 10-core TPNB were randomized into two groups. A pre-biopsy blood and urine examination was performed in both groups. Group 1 (25 patients) underwent biopsy with d...

A sheathed needle (Tru-Cut) was compared with a suction biopsy needle (Menghini) in a randomised prospective trial over 18 months to determine whether the former offered any special advantages in routine percutaneous liver biopsy. Seventy-seven consecutive biopsies were performed by a single operator. Although biopsy fragmentation was commoner with the suction needle, the length and volume of t...

PURPOSE The purpose of this study was the clinical evaluation of ultrasound-guided biopsy in comparison with ultrasound-guided fine-needle aspiration biopsy of identical, non-palpable breast lesions. MATERIALS AND METHODS From August 1997 until July 1998, 73 ultrasound-guided biopsies were performed in 66 patients with non-palpable lesions of the breast. In 18 patients (age 33-77 years) with ...

RM The primary goal of fine-needle aspiration is to acquire individual cells as opposed to tissue, which is the aim of fine-needle biopsy. Cells may not necessarily provide the stroma, or the associated architecture, of the surrounding tissue. Thus, if the surrounding architecture is needed to make a diagnosis, a fine-needle biopsy, which typically uses a core biopsy needle, should provide that.

Cancer spread along the needle track following fine needle aspiration biopsy is said to be a rare complication. The authors report a case of subcutaneous implantation of hepatocellular carcinoma following ultrasono-guided fine needle aspiration biopsy. The patient, a 67-year-old Korean male was found to have a large hepatocellular carcinoma diagnosed by fine needle aspiration biopsy. Four month...

We performed a prospective study of sixty-two patients who were managed with a closed core needle biopsy in an outpatient clinic for a soft-tissue mass or a bone tumor with soft-tissue extension between August 1, 1992, and June 1, 1994. Eight (13 percent) of the closed core needle biopsies yielded no neoplastic tissue. Two needle biopsies (3 percent), which were of myxomatous masses, did not al...

qua non of diagnosis, staging, and treatment. Most treatment protocols for malignant bone tumours are based on correct grading and staging of lesions determined by a good biopsy.1 The technical difficulty and complication rates are low for a core needle biopsy, compared with open methods, particularly in moribund patients.2 Biopsy protocols should be strictly adhered to, and compartmental segre...
