NCT07211581
Predicting post-total thyroidectomy hypocalcemia involves a combination of patient-specific, disease-related, and surgical factors. Key predictive factors include the intrinsic characteristics of the thyroid disease, pre-operative levels of calcium and vitamin D, the degree of parathyroid gland manipulation or injury, advanced age, and pre-existing hyperthyroidism. While no single factor is definitive, a low post-operative parathyroid hormone (iPTH) level is a strong indicator of developing hypocalcemia
NCT06383091
In this clinical trial, the investigators are seeking to learn if a course of voice therapy, including neck massage, stretches and pain science education in addition to voice exercise and scar massage will effectively treatment patient complaints of swallowing or voice changes after total thyroidectomy as compared to voice exercise and scar massage alone. The main questions it aims to answer are: Will neck massage, stretches and pain science education reduce patient complaints of swallowing changes after total thyroidectomy? Will neck massage, stretches and pain science education reduce patient complaints of voice changes after total thyroidectomy? Will neck massage, stretches and pain science education reduce patient complaints of scar tethering and quality changes after total thyroidectomy? Will neck massage, stretches and pain science education improve quality of life after total thyroidectomy? Participants will: Participate in 4 visits with the participant's endocrine/laryngology surgeon. One prior and 3 after surgery for endoscopic evaluation and tests. Participate in 5 Speech-Language Pathology Sessions for intervention exercises and tests. One prior and 4 after surgery. Complete a journal of the participant's Home Exercise Practice
NCT06716632
This study aims to address the existing gap in knowledge by conducting a comprehensive comparison of the incidence of hypocalcemia in patients undergoing thyroidectomy using Ligasure versus conventional ligation of vessels by knot tying. Additionally, secondary outcomes such as operative time, intraoperative bleeding, length of hospital stay, and postoperative complications will be assessed to provide a holistic understanding of the two surgical approaches.
NCT05216419
The hypocalcemia after total thyroidectomy is one of common surgical complications. It may be asymptomatic, but patients can complain of dysfunction around the mouth or extremities, stiffness or convulsion in severe cases. The incidence of transient hypocalcemia was 6.9-46%, and permanent hypocalcemia was reported to be 0.4-33%. It has been reported that the incidence of hypocalcemia after thyroidectomy is high when the difference in blood levels of parathyroid hormone and vitamin D is large before and after surgery. Therefore, it is a very important task to study the effect of using vitamin D3 (cholecalciferol), which has a better effect on the human body, on the prevention of hypocalcemia after total thyroidectomy with a long follow-up period after surgery. The department of surgery in Seoul National University Hospital intends to analyze the preventive effect "D-mac 30,000 IU" on postoperative hypocalcemia and safety of 'D-mac 30,000 IU" through a prospective randomized clinical trial. The incidence of postoperative hypocalcemia of the group taking orally taking vitamin D3 (cholecalciferol) before surgery will be compared with that of the group not taking vitamin D3 before surgery. Patients who are enrolled in this RCT are allocated to the case group and the control group. Patients in the case group are taking 30,000 IU of vitamin D3 (cholecalciferol) orally, and patients in the control group are not taking any drugs. Primary endpoint of this study is to evaluate the incidence of hypocalcemia. And secondary endpoints are to evaluate the recovery duration from postoperative hypocalcemia and the risk factors for postoperative hypocalcemia.
NCT06924242
This study aims to investigate, based on existing knowledge, the incidence of occult thyroid carcinoma in a cohort of patients with MNG, providing new insights into the prevalence and characteristics of thyroid malignancies in MNG. It seeks to contribute to optimizing diagnostic evaluations for patients with multinodular goiter.
NCT02167529
The purpose of this study is to evaluate the evolution of quality of life and voice function with different questionnaires (VIH, SF36) before and after total thyroidectomy.
NCT02089542
Reliable identification of parathyroid glands is critical to the success of thyroid and parathyroid surgery. In thyroid surgery, inadvertent injury to parathyroid glands may cause temporary or permanent hypoparathyroidism (low calcium levels needing long term treatment). In parathyroid surgery, early identification of normal and/or enlarged parathyroid glands helps in deciding on the extent of surgery and increases the chances of postoperative normal calcium levels. Methylene Blue (Methylthioninium chloride, MB) is a dye that when given intravenously in high doses, is taken up differently by thyroid and parathyroid tissue. It is currently used during parathyroid surgery by some surgeons to help identify enlarged parathyroid glands by visual examination alone. Such visual examination is unhelpful in the identification of 'normal' parathyroid tissue. MB exhibits fluorescent properties in the near-infrared range (light just beyond the visible spectrum). This can be picked up by an appropriate imaging system. This has potential to identify and differentiate between 'normal' parathyroid, 'abnormal' parathyroid and thyroid tissue during surgery. The investigators have established the feasibility of the intra-operative use of a near infra-red fluorescent imaging device called Fluobeam® and demonstrated the ability of this device to pick up near infra-red fluorescence from human tissue after administration of intravenous MB. Animal experiments have shown that doses as low as 0.1mg/kg of MB given intravenously enable fluorescent visualisation of thyroid and parathyroid glands. This study will aim to optimise the dose and timing of administration of MB in human thyroid and parathyroid surgery and to develop a protocol which would then subsequently be assessed for effectiveness in a multi-centred randomized controlled setting.
NCT01865006
The purpose of this study is to compare effect of sutureless thyroidectomy with vessel closure devices and conventional thyroidectomy with suturing on voice quality with phoniatric evaluation.
NCT01649154
The Harmonic Focus and Ligasure small-Jaw are the last device designed for thyroid surgery. The aim is to assess: 1. decrease of operative time (minutes); 2. decrease of post-operative blood loss (milliliters); 3. decrease of post-operative stay (days); decrease of post-operative complications (%, hypocalcemia, laringeal nerve demage), compared to traditional dissection in a prospective randomized trial of total thyroidectomy procedures, for benign disease.
