Prevertebral cervical approach to posterior mediastinum parathyroid adenomas.

BACKGROUND: About 4 years ago, we described the pure endoscopic cervical approach to posterior mediastinum parathyroid adenomas, which we called the "prevertebral cervical approach". At that time, we had operated on three patients and did not have enough quality videos to demonstrate this approach. After broadening our experience, we present our results and show this technique through a video. METHODS: From June 2015 to January 2021, information on patients undergoing the prevertebral cervical approach was obtained from a specific prospective database, including clinical presentation, biochemistry, preoperative imaging, surgical approach and patient outcomes. The step by step technique is described for both right- and left-sided adenomas, by means of a short video clip. RESULTS: Ten patients were operated on using this technique. Seven adenomas were right-sided and three were left-sided. The mean surgical time was 33 ± 7 min. There were neither intraoperative nor major postoperative complications. Seven patients presented with a slight subcutaneous emphysema, which did not cause complaints. All patients were discharged the day after surgery, except for one patient with a previous open neck removal of four glands due to secondary hyperparathyroidism, which required calcium replacement. Calcium and parathyroid hormone levels were normalised in the other nine patients after surgery. One patient experienced a transient recurrent laryngeal nerve injury which was spontaneously resolved within 1 month. No permanent recurrent laryngeal nerve injury was found. The postoperative cosmetic outcomes were excellent. CONCLUSION: In our experience, the pure cervical endoscopic approach has shown a high feasibility and short operation time, with excellent postoperative results regarding patient comfort, length of stay and disease cure. This approach also offers a very reasonable procedure cost, and may result in a less aggressive surgical option when compared with thoracic approaches.

Efficacy and safety of preoperative preparation with Lugol's iodine solution in euthyroid patients with Graves' disease (LIGRADIS Trial): Study protocol for a multicenter randomized trial.

BACKGROUND: Currently, both the American Thyroid Association and the European Thyroid Association recommend preoperative preparation with Lugol's Solution (LS) for patients undergoing thyroidectomy for Graves' Disease (GD), but their recommendations are based on low-quality evidence. The LIGRADIS trial aims to provide evidence either to support or refute the systematic use of LS in euthyroid patients undergoing thyroidectomy for GD. METHODS: A multicenter randomized controlled trial will be performed. Patients ≥18 years of age, diagnosed with GD, treated with antithyroid drugs, euthyroid and proposed for total thyroidectomy will be eligible for inclusion. Exclusion criteria will be prior thyroid or parathyroid surgery, hyperparathyroidism that requires associated parathyroidectomy, thyroid cancer that requires adding a lymph node dissection, iodine allergy, consumption of lithium or amiodarone, medically unfit patients (ASA-IV), breastfeeding women, preoperative vocal cord palsy and planned endoscopic, video-assisted or remote access surgery.Between January 2020 and January 2022, 270 patients will be randomized for either receiving or not preoperative preparation with LS. Researchers will be blinded to treatment assignment. The primary outcome will be the rate of postoperative complications: hypoparathyroidism, recurrent laryngeal nerve injury, hematoma, surgical site infection or death. Secondary outcomes will be intraoperative events (Thyroidectomy Difficulty Scale score, blood loss, recurrent laryngeal nerve neuromonitoring signal loss), operative time, postoperative length of stay, hospital readmissions, permanent complications and adverse events associated to LS. CONCLUSIONS: There is no conclusive evidence supporting the benefits of preoperative treatment with LS in this setting. This trial aims to provide new insights into future Clinical Practice Guidelines recommendations. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT03980132.

Prevertebral cervical approach: a pure endoscopic surgical technique for posterior mediastinum parathyroid adenomas.

BACKGROUND: Parathyroid gland mediastinal ectopia is an unusual but challenging condition in surgical management of hyperparathyroidism. Posterior mediastinum parathyroid ectopia is rare, and glands need to be removed either with a broad open cervical or thoracic approach. In recent years, several minimally invasive approaches to mediastinal parathyroid glands have been described, but for posterior mediastinum adenomas, proposed techniques are transthoracic. METHODS: The aim of this paper is to describe, to our best knowledge for the first time, a standardized pure endoscopic cervical technique to approach posterior mediastinal parathyroid adenomas which we have used in three patients. RESULTS: The technique was applied in three patients which excellent surgical, postoperative, and cosmetic results. CONCLUSIONS: Endoscopic prevertebral approach is a feasible, sure and inexpensive standardized pure endoscopic cervical approach to posterior mediastinal parathyroid adenomas, which may result in a less aggressive surgical option when compared with thoracic approaches.

Compliance with recommendations on surgery for primary hyperparathyroidism-from guidelines to real practice: results from an Iberian survey.

PURPOSE: Knowledge about compliance with recommendations derived from the positional statement of the European Society of Endocrine Surgeons on modern techniques in primary hyperparathyroidism surgery and the Third International Workshop on management of asymptomatic primary hyperparathyroidism is scarce. Our purpose was to check it on a bi-national basis and determine whether management differences may have impact on surgical outcomes. METHODS: An online survey including questions about indications, preoperative workup, surgical approach, intraoperative adjuncts, and outcomes was sent to institutions affiliated to the endocrine surgery divisions of the National Surgical Societies from Spain and Portugal. A descriptive evaluation of the responses was performed. Finally, we assessed the correlation between the different types of management with the achievement of optimal results, defined as a cure rate equal or greater than the median of all interviewed institutions. RESULTS: Fifty-seven hospitals (41 Spanish, 16 Portuguese) answered the survey. First-ordered imaging tests were neck ultrasound and sestamibi scan. Facing negative or non-concordant results, 44 % of surgeons ordered additional tests before first-time surgery, and 84 % before reoperations. When indicated, selective parathyroidectomy was an acceptable option for 95 % of institutions as first-time surgery and for 51 % in reoperations. Intraoperative parathormone measurements were used by 92 % of departments. The surgical outcomes were good in most institutions (median cure rate 97 %) and were influenced mostly by the presence of an endocrine surgery unit in the surgical department (p = 0.038). CONCLUSIONS: Practice of Iberian endocrine surgeons is consistent with current recommendations on surgery for primary hyperparathyroidism, with variability in some areas.

[Adrenal surgery in Spain: final results of a national survey]. / Cirugía suprarrenal en España: resultados finales de una encuesta nacional.

INTRODUCTION: The indications for adrenalectomy could be changing by the availability of laparoscopy and the growing detection of incidentalomas. The Endocrine Surgery Section of the Spanish Association of Surgeons conducted a survey to analyse the current indications for adrenalectomy and their results in Spanish surgical departments. MATERIAL AND METHODS: Data was gathered as regards the type of hospital and department, volume of procedures, localisation studies and pre-surgical preparations, indications, surgical approach, and results in terms of morbidity and hospital stay. The results of the centres were compared as regards their volume of activity using the Mann-Whitney Test for the quantitative variables and chi squared for the qualitative ones. RESULTS: Thirty-six centres completed the questionnaire and 301 adrenalectomies were reported to be performed in 2008. Most frequent indications were pheochromocytoma (25.2%), non-functioning adenoma (16.2%), aldosteronoma (15.9%), Cushing adenoma (11.2%), metastasis (10.3%), myelolipoma (5.6%), and carcinoma (4.9%). Laparoscopic adrenalectomy was performed in 83.7% of cases (6.7% required conversion to laparotomy). The mean hospital stay was 3.9 days for laparoscopic adrenalectomy and 7.4 days for laparotomy. High-volume units (more than 10 per year) used more frequently the laparoscopic approach (P=.019), and had a shorter overall hospital stay (P<.0001). Laparoscopic adrenalectomy was also associated with a shorter hospital stay (P<.0001). CONCLUSIONS: Laparoscopy for adrenalectomy has become the standard practice in Spain, with good results in terms of morbidity and hospital stay. High volume centres have better results as regards the use of minimally invasive surgery and hospital stay.
