BackgroundUltrasound-guided fine needle aspiration cytology (FNAC US) has been proven to be an accurate and efficient tool in thyroid nodule evaluation. Thyroid nodule aspiration can be acquired with either of two techniques: the short axis, in which only the tip of the needle is observed, and the long axis, in which the entire length of the needle is observed. Our retrospective study aimed to compare the adequacy of the two techniques.MethodsFNAC US was performed in 538 thyroid nodules between January 2019 and December 2021. Data on the technique and the diagnostic accuracy were collected.ResultsA total of 273 nodules were aspirated using the long axis technique, and 265 nodules were aspirated using the short axis technique. The diagnostic adequacies of the long axis technique were significantly higher than those of the short axis technique (92 % versus 86 %, respectively, p < 0.025).ConclusionIn our study, the long axis technique provided more accurate cytological evaluation than the short axis technique.Level of evidence: level 3. 相似文献

The effect of combined spinal epidural (CSE) anaesthesia and size of spinal needle on postoperative hearing loss after elective caesarean section The exact aetiology of vestibulocochlear dysfunction after spinal anaesthesia is unknown. Low‐frequency hearing loss occurs after spinal anaesthesia. The aim of this study was to investigate the effects of combined spinal–epidural (CSE) anaesthesia and size of spinal needle on vestibulocochlear dysfunction, using pure tone audiometry performed pre‐ and on the first and the second day postoperatively. Forty‐five patients who were to undergo elective caesarean section were evaluated. In group I, CSE anaesthesia (18 G Tuohy, 25 G Whitacre pencil‐point‐design spinal needles) was performed in 15 patients. In group II, spinal anaesthesia was performed in 15 patients with 25 G Whitacre pencil‐point‐design spinal needles and, in group III, spinal anaesthesia was performed in 15 patients with 22 G Whitacre pencil‐point‐design spinal needles. In the pre‐ and on the first and the second day postoperatively, the pure tone audiogram was performed in the audiology laboratory of our hospital, using a calibrated Kamplex Diagnostic Audiometer AC 40 in a noise‐free room. When the CSE anaesthesia group and 22 G spinal group were compared for change in hearing between the pre‐ and postoperative periods, a statistically significant difference was observed at R‐right ear 125 Hz (P < 0.025) and at L‐left ear 125 Hz (P < 0.023), and at L‐left ear 1000 Hz (P < 0.036) and at R‐right ear 1500 Hz (P < 0.006), and at L‐left ear 1500 Hz (P < 0.022). At other frequencies, the difference was insignificant. When the CSE anaesthesia group and 25 G spinal group were compared for change in hearing between the pre‐ and postoperative periods, no statistically significant difference was detected at any frequency tested. When 22 G spinal group and 25 G spinal group were compared for change in hearing between the pre‐ and postoperative periods, there was some hearing loss at low frequency, although this difference did not reach statistical significance. The positive correlation of low‐frequency hearing loss and increased pressure in the epidural space (which decrease the risk of cerebrospinal fluid leakage through the dura) suggests that cerebrospinal fluid leakage via the spinal puncture hole is not the only factor involved. Perioperative fluid replacement alone may not prevent hearing loss but CSF loss through the dural puncture site should also be prevented. 相似文献

BackgroundFine needle aspiration cytology (FNAC) is an established technique in the management of salivary gland lesions. The Milan System for reporting salivary gland cytopathology (MSRSGC) intents to standardize diagnostic categories. Current studies are trying to evaluate the diagnostic approach of this system.MethodsFNAC of salivary gland lesions were retrieved over an 11-year period. 185 FNAC specimens from 182 patients were reviewed blindly and classified according to the criteria established by the MSRSGC. 136 (74.7%) patients had follow-up of their processes.ResultsThe total number of diagnostic categories and risk of malignancy (ROM) in 185 specimens were the following: non-diagnostic 39 (21.1%; ROM 12%), non-neoplastic 35 (18.9%; ROM 0%), atypia of undetermined significance (AUS) 17 (9.2%; ROM 46.1%), benign neoplasm 75 (40.5%; ROM 4.9%), salivary gland neoplasm of uncertain malignant potential 4 (2.2%; ROM 100%), suspicious for malignancy 7 (3.8%; ROM 100%), malignant 8 (4.3%; ROM 100%). No false positives were observed in groups IVb, V, and VI in this series. The overall sensitivity, specificity, negative predictive value, positive predictive value and diagnostic accuracy were 88%, 91.8%, 96.3%, 76.7%, and 91% respectively.ConclusionThe ROM reported in our study was in keeping with ROM published by the MSRSGC. This system provides standardized information for risk stratification. The category AUS encompassed cases causing uncertainty representing a challenge in management. Defining criteria for AUS category need to be refined. The system facilitates communication between pathologists and clinicians favoring improvement in patient care. 相似文献

Hypothesis: Analysis of salivary gland lesions by FNAC and correlation with histopathology. To evaluate utility of FNAC in salivary
gland lesions.Back ground: Salivary gland lesions form about 2–6.5% of all head and neck neoplasms in adults. They are easily accessible for FNAC (Fine
Needle Aspiration Cytology) and risks of fistula formation or tumour implantation are low compared surgical biopsy. Also,
cytology can provide a distinction between asalivary and non salivary lesion, benign and malignant lesions so also specific
and non specific inflammation.
Methods: Seventy patients were studied prospectively over two years. FNAC was done using 10 cc syringes and 20–22 no. needle. Histomorphology
was assessed on routine H & E (haemotxylin and eosin) stained paraffin sections. SPAS (periodic acid Schiff) and mucicarmine
satins were also done.
Results: 80% of the lesions were neoplastic (61% benign, 31% malignant) and 20% were neoplastic. Pleomorphic adenoma was the most
frequent benign neoplasm while mucoepidermoid carcinoma was the most frequent malignant lesion. Among the non neoplastic lesions,
the maximum number of cases were of chronic sialadentis. In the present study, FNAC has a sensitivity of 94.54% and specificity
of 80.95% for neoplastic lesions.
Conclusions: FNAC was found to be a useful diagnostic tool in the evaluation of salivary gland lesions because of its simplicity, excellent
patient compliance and rapid diagnosis. This cost effective tool is invaluable in planning the surgical management of the
patient. 相似文献

Introduction and objectivesFine needle aspiration cytology (FNAC) is a globally accepted technique in the preoperative evaluations of head and neck tumours; however, the effectiveness in the interpretation of salivary glands neoplastic lesions is still controversial. The objective of this study consisted of assessing the efficacy of FNAC in preoperative diagnosis of parotid tumours.MethodsThis retrospective study was conducted using 93 patient samples with parotid gland tumoral pathology, treated at the Otorhinolaryngology Department in our institution during the 2007-2011 period. Preoperative FNAC was employed and the patients subsequently submitted to surgical excision with histopathological diagnosis of the specimen. Cytology results were classified as negative for malignancy, positive for malignancy or insufficient sample, and later compared with the definitive histological diagnosis.ResultsThe mean age of the studied sample was 52.9 years (range: 11 to 88 years); 55.9% were men. The FNAC showed significant sensitivity of 57.1%, with a specificity of 95.1%, for detecting malignancy in parotid gland tumours. The positive and negative predictive values for malignancy were 50 and 96.3%, respectively.ConclusionsFNAC is considered a simple test but of limited use for diagnostic guidance in tumour pathology of the parotid gland in our environment, mainly because of its low sensitivity. However, the high specificity and high negative predictive value of FNAC makes it a more accurate test in benign or negative result cases. 相似文献

IntroductionUltrasound sonography provides a quick method for determining which nodule to sample for fine needle aspiration biopsy in thyroid nodules. On the other hand, the computed tomography examination is not restricted by echo attenuation and distinguishes between benign and malignant nodules.ObjectiveTo compare computed tomography examinations against ultrasound/fine needle aspiration biopsy in the differential diagnosis of thyroid nodules.MethodsData regarding computed tomography examinations, sonographic finding following fine needle aspiration biopsy, and tumor histology of 953 nodules from 698 patients who underwent thyroidectomy were collected and analyzed. The beneficial score for detection of the malignant tumor for each adopted modality was evaluated.ResultsUltrasound images did not show a well-circumscribed solid mass in 89 nodules, and ultimately did not detect nodules in fine needle aspiration biopsies (false positive non-malignant nodules). Ultrasound images showed parenchymatous disease (false positive malignant nodules) in several nodules. Computed tomography examinations demonstrated higher difficulty in detection of malignant nodules of 1.0–2.0 cm size than ultrasound examination following fine needle aspiration biopsies; compared to tumor histological data, computed tomography examinations had a sensitivity of 0.879.ConclusionComputed tomography examinations are a more reliable method for differential diagnosis of thyroid nodules than ultrasound examinations followed by fine needle aspiration biopsy.Level of EvidenceIII. 相似文献

The objective of this study was to determine the efficacy of fine needle aspiration cytology in diagnosis and management of thyroid nodules. The study also evaluated the predictive value of pre-operative fine needle aspiration cytology (FNAC) in surgical decision making, by comparing the final pathological diagnosis with the initial FNAC result. All patients who underwent thyroidectomy between 1999 and 2003 were analysed. One hundred and sixty patients who underwent pre-operative FNAC were included in this study. Fine needle aspiration was accurate in 119 (74.3 per cent) patients. Fine needle aspiration cytology and histology did not correlate in 32 (20 per cent) patients and FNAC was inadequate in nine (5.6 per cent) cases. Failures were mainly noted in cases of follicular neoplasm. Our results indicate that FNAC is helpful in the diagnosis of thyroid pathology. However, complete histopathological analysis is essential to distinguish follicular adenoma from follicular carcinoma.From this study, it can be concluded that FNAC is a cost-effective method of evaluating thyroid pathology pre-operatively and plays a useful role in planning the surgical management of thyroid nodules. However, results must be interpreted with the clinical picture in mind. 相似文献

The utility of on-site microscopic evaluation of fine needle aspirates (FNAs) of the head and neck was assessed by comparing the diagnostic yield in 336 specimens obtained with immediate on-site cytopathological procurement and evaluation to that achieved in 548 cases performed without immediate on-site evaluation. Three hundred six (91%) of 336 immediate evaluation specimens were adequate for cytopathologic diagnosis, compared to 391 (71%) of 548 specimens not evaluated immediately (P < .001, chi-squared test). The higher satisfactory rate in immediate evaluation cases was related primarily to 1. immediate reaspiration of the masses until sufficient cytopathologic material was obtained for diagnosis; and 2. optimal specimen preparation. It is concluded that immediate on-site cytopathological procurement and evaluation of fine needle aspirates of head and neck masses is a valuable practice which assures a higher yield of adequate specimens compared to biopsies taken without immediate evaluation. The technique of immediate on-site evaluation of FNAs is discussed and a cost-benefit analysis of immediate on-site evaluation of FNAs is presented. 相似文献

Fine-needle aspiration cytology (FNAC) of thyroid nodules has become the primary diagnostic tool in the evaluation of thyroid nodules. However, the diagnostic utility of thyroid cytology may be limited by the presence of atypical cytologic patterns. In patients with atypical cytology in FNAC, treatment concept is not established. The purpose of this study is to correlate subcategories of atypical cytology of thyroid gland with final histologic diagnoses, and to help develop a treatment plan for thyroid nodules. We retrospectively reviewed 133 specimens of patients with atypical cytology of thyroid nodule according to preoperative FNAC. The atypical cytologic patterns were classified and divided into three groups: follicular neoplasm with nuclear atypia (FNA), nodular hyperplasia with nuclear atypia (NHA), possible papillary carcinoma (PP). Then we investigated the malignancy rates of each group. Among the 133 specimens with atypical cytology, 43 cases (32.3%) were proved to be malignant. Of the 97 cases in the FNA group, 29.9% were malignant. In the NHA and PP groups, 23.1 and 47.8% were malignant, respectively. However, there was no statistical significance in the incidence of malignancy among the three groups. There was also no statistical difference among all groups, with regard to lymph node metastasis and recurrence. In conclusion, if aspirates manifest atypical cytologic pattern, surgery should be considered, especially if the results are categorized as PP. Intraoperative frozen section should be confirmed and the extent of resection should be determined by final pathology. 相似文献
