<b><i>Introduction:</i></b> There are few studies on the role of puncture feeling in thyroid nodules during ultrasound-guided fine-needle aspiration cytology (US-FNAC), although it is expected to become a new predictive technique. We aimed to analyze the importance of puncture feeling in combination with US-FNAC and investigate whether it can be used as an indicator to predict the nature of thyroid nodules. <b><i>Materials and Methods:</i></b> From January 1, 2018, to October 31, 2020, a total of 623 thyroid nodules were included. Puncture feeling was classified as “soft,” “hard,” or “hard with grittiness.” The correlation between puncture feeling and postoperative pathology and the diagnostic value of FNAC combined with puncture feeling were analyzed, and the influence of thyroid nodule size on puncture feeling, FNAC, and FNAC combined with puncture feeling was studied. We further explored the correlation between puncture feeling and histopathology in Bethesda III and IV thyroid nodules. <b><i>Results:</i></b> There was a significant correlation between puncture feeling and postoperative pathology (<i>p</i> &#x3c; 0.001). The sensitivity, negative predictive value, and total coincidence rate of US-FNAC combined with puncture feeling for the diagnosis of thyroid nodules were higher than those of US-FNAC alone (96.1, 83.6, and 94.7% vs. 89.0, 65.5, and 89.7%, respectively). Thyroid nodule size was the influencing factor for puncture feeling, FNAC, and FNAC combined with puncture feeling (<i>p</i> &#x3c; 0.05 for all). The area under the curve for puncture feeling, FNAC, and FNAC combined with puncture feeling for thyroid nodules of size ≤1 cm was greater than for modules of size &#x3e;1 cm. Puncture feeling was of great value in diagnosing Bethesda III thyroid nodules (<i>p</i> &#x3c; 0.001), and all Bethesda IV thyroid nodules had puncture feeling of soft. <b><i>Conclusion:</i></b> Puncture feeling is of great value during US-FNAC. “Hard” and “hard with grittiness” were indicators for malignancy, while “soft” indicated that the thyroid nodule was likely to be benign. The diagnostic value of US-FNAC combined with puncture feeling for thyroid nodules is higher than US-FNAC alone, especially when nodule size is ≤1 cm. Puncture feeling is of great value in predicting the nature of Bethesda III thyroid nodules.

Objective: To assess the Solitary thyroid nodules by surgeon-performed ultrasound-guided FNAC and evaluate with the histopathological findings. Methods: This study includes 100 Consecutive patients of a solitary thyroid nodule which were presented to the Outpatients Department of Surgery during the period of two years from September 2016 to August 2018. Exclusion criteria were patients with extra-thyroid swelling, diffuse goiter and multinodular goiter. All patients with a solitary thyroid nodule underwent Surgeon –performed ultrasound-guided FNAC in the department of Radiology. After thyroid surgery, thyroid specimens were sent for histopathology and evaluate with FNAC findings. Results: The study included hundred patients with solitary thyroid nodule, 75(75%) female and 25 (25%) male with a ratio of F 3:1M. The age of the patients ranged from 15-75 years with a mean age of 35 years. The result of 100 cases of Surgeon –performed Ultrasound –guide FNAC of a solitary thyroid nodule were inconclusive in 10 cases (10%), Non-neoplastic in 60 cases (60%) and Neoplastic lesions in 30 cases (30%). After evaluation of findings from FNAC and histopathology, four cases with benign FNAC (adenomatous/colloid Goiter) turnout as neoplastic (papillary carcinoma) on histopathology and six cases with neoplastic FNAC (papillary carcinoma), just two cases turnout as benign (nodular colloid goiter with cystic degeneration) on histopathology. In present study Surgeon – performed Us FNAC has found to be 87.5% sensitive, 95.3% specific and 92.0% diagnostic accuracy. Conclusion: Surgeon – performed Ultrasound-guided FNAC is a safe, simple and accurate technique in the diagnosis of solitary thyroid nodule. doi: https://doi.org/10.12669/pjms.35.4.537 How to cite this:Jat MA.

Abstract Background: Ultrasound-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. Methods: FNAC US was performed in 357 thyroid nodules between January 2019 and December 2019. Data on the technique and the diagnostic accuracy were collected. Results: A total of 181 nodules were aspirated using the long axis technique, and 176 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. technique (93% versus 83%, respectively, p< 0.001). Conclusion: In our study, the long axis technique provided more accurate cytological evaluation than the short axis technique.

Background: Fine-needle aspiration cytology (FNAC) is recommended as a decisive diagnostic step in the workup of patients with nodular thyroid disease. Unfortunately, FNAC can miss malignancies in smaller and deeper nodule. Ultrasound guided FNAC (US-FNAC) can reduce this error in suspicious thyroid nodule. Objectives: To find out the correlation of USG guided FNAC with postoperative histopathology in diagnosis of thyroid nodule. Methods: After obtaining clearance and approval from Institutional Review Board, all 45 patients of thyroid nodule who were admitted in the Department of Otolaryngology – Head & Neck surgery of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka from April 2017 to August 2018 and had fulfilled the inclusion and exclusion criteria were selected for the study. Each patient was assessed before surgery by USG guided FNAC and post operatively by histopathology. Results: In this study mean age of the respondents was 33.33 yearswith SD±10.84. Male female ration was 1:5.4. USG guided FNAC was reported by ‘The Bethesda System for Reporting Thyroid Cytopathology’ (TBS-RTC).Of the 45 specimens 2 samples were nondiagnostic or unsatisfactory (Class I), 26 samples were benign (Class II), 2 samples were showing Atypia of Undetermined Significance or Follicular lesion of Undetermined Significance (Class III), 6 were showing follicular neoplasm or suspicious for a follicular neoplasm (Class IV), 5 samples were suspicious for malignancy (Class V) and 4 samples were positive for malignancy (Class VI). On comparison of ultrasound guided FNAC with histopathology the sensitivity for correct diagnosis was 94%, specificity was 93%, positive predictive value was 88%, negative predictive value was 96% and accuracy was 93%. Pearson’s correlation coefficient was 0.85 which is very strong for positive relationship. Conclusion: USG guided FNAC is the most accurate method for diagnostic evaluation of thyroid nodules.
