Filter by:Transoral endoscopic thyroid surgery is a emerging surgical technique for thyroid surgery. This study to investigate the need for postoperative antibiotics in transoral endoscopic thyroid surgery.
Use of ethanol injection in treatment of cystic thyroid nodule
It has been shown that insulin might be involved in the pathogenesis of thyroid growth. Objective To evaluate the impact of IR and metformin use on the volume of benign thyroid nodules (TNs). Methods A randomized clinical trial to placebo (P) or MTF use. Previous fine needle aspiration confirming the diagnosis is necessary to inclusion. Patients will receive similar tablets of MTF and placebo and instruct to take 3 tablets/day of MTF (500mg/tablet). Thyroid volume, as TN volume, will be assess by ultrasound, both in the beginning, six months and one year after randomization, by the same researcher blinded regarding location group. Blood samples to measure: TSH, FT4, TPO-Ab, lipid profile, glucose and insulin were done after 8h fasting.
This clinical trial studies how well ultrasound elastography works in assessing the cancer status of potentially malignant thyroid nodules.
The purpose of this registry is to collect uniform genomics-centered data on patients with nodular thyroid disease and cancer in a prospective fashion. After initial clinical evaluation patients with thyroid nodules will undergo standard ultrasonographic evaluation and a needle biopsy of the thyroid (fine needle aspiration (FNA) or core biopsy) as clinically indicated. Biopsy samples will be evaluated cyto-pathologically. A molecular/genomic profiling will be obtained using Thyroseq v2 test. Surgical treatment will be performed as per clinically determined indications. Standard surgical pathology will be processed and reported per the institutional policy and procedures. A molecular/genomic profiling will be obtained using Thyroseq v2 on the surgical specimen. All patients undergoing thyroid nodule work-up may be enrolled. The registry will collect patient demographic and clinical data, cytopathology reports, and surgical pathology reports and slides (if/when a review is required).
The investigation of thyroid nodules is limited by the fact that up to 49% of the fine needle aspirations (FNA) performed are of "indeterminate cytological signification". Moreover, no fully reliable molecular marker for thyroid cancer have been described. The goal of this project is to study the expression of a specific kind of protein convertase in benign and in malignant thyroid nodules to determine its potential as a biomarker.
Thyroid surgery has been developed as a new technique for zero scar in surgery by applying transoral endoscopic thyroidectomy with sublingual approach. The new technique is locating the surgery which pierced through floor of mouth, cause severe tissue damage, high complication, and conversion rates to open surgery and surgical difficulties due to limitation of movement. Nevertheless, each report is still including small number of patients. Recently, the transoral endoscopic thyroidectomy vestibular approach (TOETVA) has been proven feasible and safe in several overseas centers. Moreover, a successful TOETVA case was reported in local media in the late last year. Hence, this study is for evaluating the feasibility and safety of the TOETVA prospectively at a tertiary referral center in Hong Kong. The following are the procedure of the study: 1. Recruit patients from the clinic. 2. Patients will receive treatment within 3 months 3. Patients will have different assessments like Ultrasonography assessment, Fine needle biopsy, Direct laryngoscopy, and Cosmectic scoring in Pre-operation, post-operation 2 week, post 1 month, post 3 month, post 6 month and post 12 month. 4. Patients will be monitoring by the same team after the study.
Regular thyroid diagnostics versus augmented thyroid work-up with additional I-124 PET/US fusion for metabolic-sonographic nodule allocation in patients with benign thyroid diseases
As many as 70-85% subjects diagnosed with a follicular lesion on biopsy and undergoing surgery will have benign lesions verified by histopathology after surgery. Currently there is no method of pre-operatively diagnosing benign follicular lesions, as a result these subjects will have had surgery for diagnosis of a benign lesion. The aim of this study is to see whether shear-wave elastography, a new ultrasound technology can help pre-operatively diagnose benign follicular lesions. If successful, a lot of patients will not need surgery for the diagnosis of a benign lesion. The main goal of this study will be to evaluate the diagnostic accuracy of a new ultrasound technology (shear-wave elastography - SWE) for the diagnosis of malignancy in follicular lesions. Participants who have been diagnosed with a follicular lesion on thyroid biopsy and are scheduled for thyroid surgery will be eligible to participate. All participants will undergo a detailed ultrasound examination prior to their surgery. The results of the ultrasound will be compared with histopathology after surgery to test the diagnostic accuracy of SWE.
A clinical trial is proposed, to clinically validate the diagnostic performance of a new genetic test developed in Chile. It will determine the nature of thyroid nodules that have been informed as indeterminate by cytology through a fine needle aspiration (FNA). The Genetic Classifier for Indeterminate Thyroid Nodules is a quantitative gene expression test, that combines the results for a panel of 10 biomarkers (CXCR3, CCR3, CXCl10, CK19, TIMP1, CLDN1, CAR, XB130, HO-1 and CCR7), to generate a single number score. It is indicated on patients with a thyroid nodule informed by cytology as indeterminate (Bethesda III and IV, according to The Bethesda System for Reporting Thyroid Cytopathology). This test would be used by taking a sample with a fine needle aspiration (FNA) and thus, being able to predict, with high accuracy, benign nodules that do not require surgery.
