Filter by:This study will investigate the usefulness of an optical probe in the differentiation of thyroid cancer from normal thyroid tissue in a thyroidectomy specimen.
Ultrasound-guided ethanol ablation is an effective treatment modality for patients with cystic thyroid nodules (cystic portion > 90%); however it is less effective in predominantly cystic thyroid nodules (90% > cystic portions > 50%). The volume reduction after EA has been reported 64% - 69.8% for predominantly cystic thyroid nodules. EA is insufficient for 26% (27/103) of patients with predominantly cystic thyroid nodules. Radiofrequency ablation to patients with incompletely resolved clinical problems after EA and the mean volume reduction ratio was 92% at 6-month follow-up. It is well known that RF ablation is effective in both predominantly cystic and solid thyroid nodules. Although RF ablation has effectively treated the patients who were unsatisfactory after EA, to the best of our knowledge, no study to date has compared these two ablation techniques. Therefore investigators performed a prospective randomized study to compare single-session RF ablation and EA for treating predominantly cystic thyroid nodules.
Shear wave ultrasound elastography is a new technique of finding the softness or hardness in tissue by applying a "push" generated by the machine. This technique will help in diagnosing malignancy in the thyroid gland without biopsy and avoiding biopsy in noncancerous nodules.
This single-blind prospective randomized study was designed to assess the efficacy and safety of the use of Surgicel® compared to the use of conventional surgical procedures (ligatures and bipolar electrocautery alone) to achieve hemostasis in thyroid surgery
Thyroid nodules are common problems and although > 95% are stated to be benign, they may cause some problems like hyperthyroidism, compression symptoms, and cosmesis associated with their function, size and localization. Especially for these nodules, patients undergo surgery and face up with the problems associated with surgical complications although they are not cancer. In some studies, radiofrequency ablation previously used for intrabdominal tumors like hepatic metastasis...,was stated to be efficient in the treatment of benign thyroid nodules and in some recurrent thyroid cancer cases. Therefore, the investigators decided to use this method in our patients having nodules like previously mentioned and see the efficacy and safety of the technique.
Percutaneous radiofrequency thermal ablation (RTA) was reported as an effective tool for the management of thyroid nodules (TNs). This study aims to validate RTA as a valid approach for patients with compressive TNs for whom surgery is contraindicated or refused. Two groups of subjects with TNs (one group to treat with RTA and a matched untreated control group) will be evaluated in term of TN volume, thyroid hormones and clinical symptoms.
The study is an open, prospective multicenter study. According to the statistical sample size calculation 593 patients with thyroid nodules ≥ 5mm in size will be included in the study. Reference methods are cytology obtained by Fine needle aspiration biopsy (FNAB) or histology obtained by surgery. All patients will receive an B-mode and Duplex ultrasound examination of the thyroid gland, as well as Realtime Elastography of thyroid nodules. Results of B-mode and Duplex ultrasound are compared to Realtime Elastography to evaluate the additional value of Realtime Elastography in the diagnostic work up of thyroid nodules.
Define an ultrasound/elastography benignity criteria in strategy management of a patient population carries one or more thyroid nodules.
The main objective is to compare 12 month complication rates between a new surgical method for thyroidectomy (robot-assisted endoscopic thyroidectomy via a sub-clavical approach) and open thyroidectomy.
The purpose of the investigators study is to retrospectively evaluate the predictors of malignant thyroid nodules and established an useful scoring system based on sonographic findings and demographic data.
