Background: Blind percutaneous pleural biopsy has traditionally been performed to investigate the etiology of exudative pleural effusion in which the initial thoracocentesis has been non- diagnostic. In view of the increasing use of image-guided and thoracoscopic pleural biopsies, this study examined the role of blind Abrams pleural biopsy in the investigation of the exudative pleural effusion ...

The technique of needle muscle biopsy using the Bergstr öm needle has been in routine use in our muscle clinic since 1978. In an initial feasibility study 24 children had a needle and an open biopsy performed simultaneously through extension of the same incision and 22 had identical interpretation of the needle and open biopsies. Needle biopsies have subsequently been performed in 674 children ...

Introduction: Chest wall tumors can be either primary, metastatic or radiation induced. Moreover, it can be due to involvement by lung or breast cancer. Although clinical and radiological assessments are important in evaluation of patients with chest wall tumors; the histo-pathological diagnosis remains the most important factor in determining the appropriate management. One of the methods to g...

Fine needle aspiration biopsy is the most feasible, safe, and accurate diagnostic tool for thyroid nodule diagnosis. The development of a sinus tract between thyroid gland and the skin through needle tract after fine needle aspiration biopsy is an extremely uncommon phenomenon. In this paper, a 71-year-old man presenting with a swelling and discharge on the anterior neck wall was reported. Simi...

and nonpalpable breast lesions is a safe and effective alternative to fine-needle aspiration and needle-localized breast excisional biopsies (1, 2). It can reduce the need for a two-stage procedure and can improve the surgical and oncological outcomes (3). However, one disadvantage of this technique for sampling breast cancer is the possible seeding of malignant tumor cells along the needle tra...

Patients with pathological complete remission (pCR) after treated with neoadjuvant chemoradiotherapy (nCRT) have better long-term outcome and may receive conservative treatments in locally advanced rectal cancer (LARC). The study aimed to evaluate the value of forceps biopsy and core needle biopsy in prediction of pCR in LARC treated with nCRT. In total, 120 patients entered this study. Sixty-o...

Despite the use of advanced radiological investigations, some liver lesions cannot be definitely diagnosed without a biopsy and histological examination. Laparoscopic Tru-Cut biopsy of the liver lesion is the preferred approach to achieve a good sample for histology. The mechanism of a Tru-Cut biopsy needle needs the use of both hands to load and fire the needle. This restricts the ability of t...

This paper discusses the virtual prostate needle biopsy system and the construction of the virtual prostate model, considering the actual distribution of prostate abnormalities. A needle biopsy simulation is performed for the constructed virtual prostate, and the actual biopsy procedure in the clinical situation is evaluated. The prostate needle biopsy is a histologic diagnosis procedure in whi...

BACKGROUND The Gleason score has been shown to offer important information with regard to prognosis and therapy for patients with adenocarcinoma of the prostate gland. In this study, Gleason scores, as determined by 18-gauge core needle biopsies, were compared with both Gleason scores and the pathological staging of corresponding radical prostatectomy specimens. METHODS Records of 78 consecut...
