Vaiman M, Mizrakli Y, Taha A, Gavriel H. An individual approach to intraoperative parathyroid hormone measurement during total thyroidectomy. Am J Otolaryngol 2024; 45:104159. [PMID: 38113776 DOI: 10.1016/j.amjoto.2023.104159] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2022] [Revised: 12/03/2023] [Accepted: 12/03/2023] [Indexed: 12/21/2023]
Abstract
PURPOSE Hypocalcemia is a common complication of thyroidectomy. Measurement of the intraoperative serum parathyroid hormone (PTH) levels became an established technique but it requires further improvements. We aimed to assess intraoperative PTH level testing results against the hypothesis that the PTH assay may be performed almost immediately after thyroid gland removal. METHODS A retrospective cohort study. During total thyroidectomy surgery, the patients had PTH levels measured at the cutting time and again immediately after the thyroid gland is removed. Post-operatively, serial total blood calcium levels were obtained twice daily and recorded. RESULTS Among 63 enrolled patients, 39 had multinodular goiter, 15 thyroid carcinoma, and nine had Graves' disease. The mean age was 59.8 ± 15.3 years, 43 females. The mean PTH level before surgery was 45.8 ± 22.0 pg/mL. Post-operatively, 11/63 patients developed hypocalcemia with serum calcium levels <8 mg/dL. Four patients with ≥50 % decrease in PTH concentration were normocalcemic a day after surgery and were discharged early. Four patients with ≥70 % PTH decrease were treated accordingly during prolonged hospitalization and did not suffer from permanent hypocalcemia. The cut-off value of 70 % decrease after the gland removal was able to predict postoperative hypocalcemia with a sensitivity of 100 %, specificity 82.9 %, PPV 60.0 % and NPV 100 %. CONCLUSION Measurements of intraoperative PTH may not be performed at fixed time intervals but after 1-2 min after removal of the thyroid gland. Defining those not at risk would allow the majority of patients to be waived from post-operative blood calcium testing and safely discharged early after surgery.

Wu J, Ebrahim AK. Ethnic disparities for thyroid surgery. ANZ J Surg 2020; 90:2527-2531. [PMID: 33135832 DOI: 10.1111/ans.16410] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2020] [Revised: 09/27/2020] [Accepted: 10/03/2020] [Indexed: 01/25/2023]
Abstract
BACKGROUND Significant health disparities exist between Māori and non-Māori patients in New Zealand. Māori patients treated medically for their thyroid disease are less likely to be euthyroid. The prevalence of thyroid disease and characteristics of Māori presenting for thyroid surgery has not been well studied. We aim to assess the differences in ethnic representation for thyroid surgery. METHODS A retrospective analysis of cases performed between 2009 and 2019 at the Otolaryngology/Head and Neck Department in Waikato District Health Board (DHB) was completed. All patients who received a thyroid operation were included and divided into Māori and non-Māori groups. Clinical and operation notes were reviewed and the duration of presenting symptoms, weight, volume and diagnosis of the thyroid gland were assessed. RESULTS A total of 93 patients were included in our study, of whom 71 patients were female and 22 male with 37 being Māori and 56 non-Māori. Māori patients had significantly higher rates of retrosternal extension, compressive symptoms, post-operative complications, delayed presentation and larger thyroid goitres when compared to non-Māori (P < 0.05). CONCLUSION Our study confirms that there is a significant ethnic disparity for Māori patients requiring thyroid surgery. This highlights an additional poor health outcome for Māori compared to non-Māori patients.

Gland Surg 2020; 9:392-400. [PMID: 32420264 PMCID: PMC7225497 DOI: 10.21037/gs.2020.03.43] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2019] [Accepted: 03/05/2020] [Indexed: 11/06/2022]
Abstract
BACKGROUND Retrosternal goiter refers to when the thyroid gland extends from the neck to the substernal portion, descending below the thoracic inlet into the mediastinum. It is typically accompanied by compressive symptoms, and most patients need to undergo surgery. This retrospective study set out to analyze the surgical approach to retrosternal goiter and to evaluate perioperative complications, with the aim of recommending best surgical technique. METHODS We carried out retrospective analysis of 115 patients with retrosternal goiter treated at our center between May 4, 2011 and March 19, 2019. We analyzed patient characteristics, surgical methods, and perioperative complications using SPSS. RESULTS Of the 115 patients in our study, 112 underwent thyroidectomy by cervical approach, with only 3 requiring an extracervical approach. The median age of the patients was 52.3 years, and the majority were female (81.74%). Most of the patients (73.91%) experienced no symptoms but were diagnosed with tracheal compression during surgery or preoperative imaging examination. Ninety-eight (85.22%) of our patients underwent preoperative evaluation of their condition by CT imaging. No obvious surgical contraindications were found before thyroid function tests. The mean operation time was 115.11 min, and the average amount of bleeding during surgery was 54.43 mL. The mean postoperative hospital stay was 5.38 days. In 109 cases (94.78%), the goiter was found to be benign, and malignancy was diagnosed in 6 patients (5.22%). Of the 112 patients who were treated with the cervical approach, 7 (6.25%) experienced recurrent laryngeal nerve palsy; 6 of these cases were transitory and 1 was permanent. The number of patients treated by cervical and extracervical approach who experienced transient hypocalcaemia was 23 (20.54%) and 2, respectively. Transient hypoparathyroidism affected 16 patients (14.29%) treated by cervical approach. Two patients had tracheomalacia phenomenon and one patient had pleural effusion after surgery. No cases experienced permanent hypocalcemia, permanent hypoparathyroidism, postoperative hematoma, tracheostomy, or death. CONCLUSIONS Retrosternal goiter surgery is challenging for surgeons. The best surgical approach for the patient should be based on CT scan evaluation. In our study, based on preoperative CT imaging and in-operation evaluation, 50% of the tumor volume was located below the thoracic inlet and 50% of the tumor volume was located above the thoracic inlet in almost all of the patients. Both sections could be successfully removed via a cervical incision, and no obvious complications were observed during the perioperative period. With careful planning and execution before surgery and meticulous operation during surgery, most retrosternal goiters can be safely treated by cervical approach.

CLINICAL PATHOLOGY (THOUSAND OAKS, VENTURA COUNTY, CALIF.) 2020; 13:2632010X20916741. [PMID: 32363342 PMCID: PMC7180302 DOI: 10.1177/2632010x20916741] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/25/2019] [Accepted: 03/10/2020] [Indexed: 11/17/2022]
Abstract
BACKGROUND The term goiter is used to describe any abnormal growth of the thyroid gland, which can be diffuse or nodular, and can be associated with normal, diminished, or increased thyroid function. Multinodular goiter is a common disease whose prevalence increases at age 50. Clinical manifestations can be due to thyroid function impairment or related to size and location of the gland with compressive symptoms. Intrathoracic location is less frequent, can be mistaken with pulmonary lesions and usually implies a difficult surgical approach. CASE PRESENTATION A 66-year-old woman with a history of subtotal thyroidectomy presented with 7-month dyspnea, dry cough. There was no evidence of neck masses, or jugular engorgement. Physical examination was normal. Chest x-ray showed an 11 cm mass in the upper right hemithorax. Computed tomography (CT)-scan, showed calcifications, and compression of the superior vena cava without infiltration, the right subclavian vein and left displacement of the trachea. Distinction between intrapulmonary or mediastinal location was not clear. Biopsy showed thyroid origin, and bilateral thoracotomy was performed with confirmation of a giant multinodular goiter. CONCLUSIONS Intrathoracic goiter should undergo surgical or ablative management if compressive symptoms of the airway and cervical or thoracic vessels are present. The large size of the tumor along with the presentation after thyroidectomy and the seeming location in the right upper lobe made this particular case striking. Specially in the elderly, multidisciplinary perioperative management is key for a successful recovery.
