BACKGROUND Fine-needle aspiration breast biopsy has been used increasingly as an alternative to excisional biopsy. The purpose of this study is to evaluate the accuracy of fine-needle aspiration with histopathologic confirmation. METHODS A retrospective study was performed using a computer database over a 5-year period. All women who had had fine-needle aspiration breast biopsy with histopath...
This paper describes the results of transproctoscopic fine needle aspiration cytology in the diagnosis of rectal lesions. Fifty one consecutive patients referred with a presumptive diagnosis of rectal mass were subjected to proctoscopic examination when fine needle aspiration cytology, brush cytology and biopsy samples were taken. Of the 30 patients of malignancy of rectum in whom all the three...
56 malignant bone neoplasms (15 primary and 41 metastatic), diagnosed by fine-needle aspiration biopsy, are reported. 100% diagnostic accuracy was achieved. The results indicate that fine-needle aspiration biopsy can be a substitute for open surgical biopsy in selected cases.
BACKGROUND AND STUDY AIMS Two 22G needles with similar designs, apart from the absence (A) or presence of a side port (B), are available for endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA). The side port was designed to increase diagnostic yield but this advantage was unproven. This study evaluated the difference in diagnostic yield between both needles in pancreatic masses. P...
S12 ENDOSCOPIC ULTRASOUND / VOLUME 6 / SUPPLEMENT 1 / AUGUST 2017 diagnostic value of specimens obtained with the new 20-gauge ProCore biopsy needle. Follow-up data are required to confirm the diagnostic accuracy of this agreement. DOI: 10.4103/2303-9027.212302
Telepathology is useful when distance is an obstacle to timely diagnosis. Performance of fine-needle aspiration (FNA) at locations distant from cytopathologists can limit timely assessment of adequacy and preliminary diagnosis. We evaluated a telepathology system for consultation between residents and faculty for assessment of FNA specimen adequacy and preliminary diagnosis using 100 consecutiv...
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.
BACKGROUND The negative predictive value of endoscopic ultrasonography-guided fine needle aspiration for the diagnosis of solid pancreatic lesions remains low, and the biopsy specimens are sometimes inadequate for appropriate pathological diagnosis. AIMS To evaluate the usefulness of a novel method of contrast-enhanced harmonic endoscopic ultrasonography-guided fine-needle aspiration for the ...
Pre-operative fine-needle aspiration biopsy findings have been compared with those of post-operative histopathology in 146 patients with parotid masses. Post-operative histology showed 124 benign and 22 malignant lesions: pre-operative fine-needle aspiration biopsy correctly identified 118/124 (95.1%) benign masses with an accurate classification of the tumour in 111/118 cases (94%). Fine-needl...
