“…The main anatomic parts of Homo sapiens in which imageguided localization techniques are useful are the breast, lung, liver, thyroid, parathyroid, kidney, and other soft tissues and organs such as lymph nodes. Localization studies remain significant in neck-endocrine surgery and thyroidology to date and provide vital clues for both surgeon-performed US examinations and all thyroidologists [5][6][7][8][9] . In breast lesions, the main indications are preoperative localization of nonpalpable lesions that are only visible on imaging; this imaging guides surgeons for a safe intervention aiming at an R0 resection and a good cosmetic result.…”
OBJECTIVE: This study aimed to evaluate our experience with the use of Magseed, the magnetic metallic marker, as a localization technique followed by Sentimag probe detection in patients with solitary intra-abdominal local metastases with subsequent resection of the lesions. METHODS: Five patients underwent resection after the lesion was marked with the Magseed magnetic marker. Prior to the surgery, a computed tomography scan of the chest and abdomen and/or positron emission tomography was performed to rule out the dissemination of the disease. The indication for surgery was evaluated in a meeting of a multidisciplinary team, and the placement of the magnetic marker under computed tomography control had been performed the day before the planned procedure. RESULTS: The present preliminary outcomes have revealed that Magseed might be a promising technique that is feasible and safe, particularly when the postsurgical anatomic conditions in the abdominal cavity are altered and the lesions are not visible or palpable. Surgical extirpation of lesions occurred without complications in each case. In all the cases, the resection was complete and curative, and one wound infection in all (20%), without any major complications, had occurred. The mean hospital stay was 6.6 days. CONCLUSION: Magseed utilization, as a localization technique, followed by Sentimag probe detection in intra-abdominal tumors has not been reported before. Improving the visualization and, consequently, the precise marking of the lesion with subsequent radical removal can prevent insufficient or excessive removal of healthy tissue, leading to a faster diagnosis and better overall clinical outcomes.

“…Very recently, Shumrick et al [22] carried out a study to compare the diagnostic capability between 25G and 27G needles for ultrasound-guided fine-needle biopsy of thyroid nodules, and they concluded that a 27G needle for FNBs yields better diagnostic information than 25G needles. Sengul et al [23][24][25][26][27] have recommended that Thy MIFNA with a 27G fine-needle could be applied in the ultrasonography-guided FNA procedure due to low rates of Category I (TBSRTC, 1st and 2nd editions.) and low severity of pain.…”
ObjectiveThe objective of the study is to analyze the influencing factors on the results of thyroid fine-needle aspiration biopsy (FNAB).MethodA total of 339 patients who underwent FNAB in our hospital from December 2018 to July 2021 were retrospectively selected. The patients were chosen according to the gender ratio, age, and thyroid ultrasound characteristics and were divided into three groups: (1) a 22G needle vacuum aspiration group (Group 1, n = 85), (2) a 22G biopsy needle non-vacuum aspiration group (Group 2, n = 50), and (3) a 25G biopsy needle non-vacuum aspiration group (Group 3, n = 204). Patients in these groups were evaluated for determining the FNAB dissatisfaction rate of pathological samples. A bivariate regression analysis of independent risk factors related to the unsatisfactory pathological diagnosis of samples was performed.ResultsThe specimen dissatisfaction rates of the three groups were 22/85 (25.9%), 15/50 (30%), and 18/186 (9.7%), respectively. The overall sample dissatisfaction rate was 55/339 (16.2%), and the sample satisfaction rate of Group 3 was higher than that of Groups 1 and 2 (P < 0.05). Logistic bivariate regression analysis showed that the age of the patients and the capillary sampling needles and aspiration methods were two independent risk factors for determining the dissatisfaction rate of FNAB pathological samples.ConclusionA 25G capillary sampling aspiration biopsy needle was selected to perform FNAB in thyroid nodules without vacuum aspiration, which could effectively improve the accuracy of FNAB results with a high specimen satisfaction rate.
“…Debate is still ongoing on an optimal needle size for thyroid FNA cytology in thyroidology. In this sense, we reported a favorable non-diagnostic cytology rate on a sum of 500 nodules in 425 eligible consecutive outpatients during 38 months, involving ultrasonography (US)-guided FNA with a surgeon-performed US (SUS) in thyroid nodules with 27-G fine needles [5][6][7][8][9][10][11][12] . Therefore, would the outcomes of the study at that point be altered as they had harnessed significantly (i) finer or (ii) larger needle sizes?…”

This issue merits further investigation. We thank Andreda et al. 1 for their valuable study.
