Abstract
INTRODUCTION Quality of life (QoL) in thyroid cancer patients is comparable to patients with other tumours with worse prognosis. The aim was to evaluate QoL in Colombian patients with thyroid carcinoma and to explore the association of QoL scores with patient features. METHODS This is a cross-sectional study. The present research was carried out from data obtained for the validation study of the Spanish version of the THYCA-QoL. Adult patients with thyroid carcinoma who underwent total or partial thyroidectomy were included and asked to complete the Spanish-validated versions of the THYCA-QoL and EORTC QLQ-C30 questionnaires. The scores of each domain and single items underwent linear transformation to values of 0-100. Comparisons of scale scores with clinical variables were performed. RESULTS We included 293 patients. The global EORTC QLQ-C30 score was 73.2±22.1 and the domains with poorer values were emotional and cognitive and the symptoms with poorer values were insomnia and fatigue. The global THYCA-QOL score was 28.4±17.8. The domains with poorer values were neuromuscular and psychological and the single items with poorer values were headaches and tingling hands/feet. CONCLUSION Colombian patients with thyroid cancer have a good prognosis, but they experience important problems related to QoL. QoL was influenced by demographic and clinical factors such as age, sex functional status and clinical stage.

Unilateral axilo-breast approach (UABA) with gas insufflation versus open conventional hemithyroidectomy: A prospective comparative study. Cir Esp 2023; 101:107-115. [PMID: 36100055 DOI: 10.1016/j.cireng.2022.09.014] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2021] [Accepted: 02/17/2022] [Indexed: 11/16/2022]
Abstract
BACKGROUND The objective of this study was to compare with the conventional open approach, the surgical and aesthetic results of endoscopic thyroidectomy via unilateral axillo-breast approach (UABA) with gas insufflation in patients with a unilateral thyroid nodule. METHODS Between August 2017 and August 2020, a prospective comparative cohort study was carried out in patients proposed for hemithyroidectomy. The patients were assigned to one type of approach (Open or Endoscopic) in a successive manner. Surgical results and aesthetic satisfaction at hospital discharge and during the 12-month follow-up were evaluated and compared between both groups. RESULTS A total of 200 patients were included in the study: 100 for the Open approach and 100 for the Endoscopic. The baseline patient characteristics were similar between both groups. Total operative time was longer in the Endoscopic approach, due to the time required for subcutaneous dissection (the hemithyroidectomy time was similar in both groups). There was no significant difference in the frequency of major complications. The length of hospital stay was longer (for 1 day) in the Endoscopic group. The aesthetic satisfaction of the patients was significantly higher in the Endoscopic than in the Open group (p < 0.001), at hospital discharge and at 12-month follow-up. CONCLUSION UABA with gas insufflation for hemithyroidectomy represents a safe and effective therapeutic option for the treatment of unilateral benign thyroid pathologies.

Abstract
INTRODUCTION Trans Oral Endoscopic Thyroidectomy through Vestibular Approach (TOETVA) allows access to the thyroid with the best cosmetic results as there are no visible scars. METHODS Here we present a prospective observational study of 53 patients which underwent TOETVA from July 2017 to June 2021. RESULTS Fifty-two cases (98.1%) cases were women (median age 44 years old). Thyroid nodule was the main surgical indication accounting 73.6% of cases. We performed 42 lobectomies and 11 total thyroidectomies; 4 left Central Neck Dissection (CND) were also associated. The median surgical time for port placement was 14 min and for lobectomy, total thyroidectomy and left CND were 80, 140 and 30 min, respectively. The median of hospital stay was 2 days. Dysphonia was present in 4 patients; however, laryngoscopy only confirmed laryngeal nerve impairment in 2 cases, one of them classified as permanent (1.6%). In those patients that underwent total thyroidectomy, the rate of transient hypoparathyroidism was 18.2% whereas permanent was 0%. Regarding complications associated to the new approach, transient chin numbness appeared in all patients with a variable degree of intensity. CONCLUSTIONS Transoral surgery is a recent approach in our Unit. Our results, based on the first 53 patients, show that it is a safe and effective approach when performed in appropriately selected patients offering the best cosmetic result. Besides, new complications associated to the approach has been shown to be transient.

Abstract
BACKGROUND Hypocalcemia is a common complication of total thyroidectomy; transient hypocalcemia has been reported in up to 68% of the patients. MATERIALS AND METHODS Chart review of all patients undergoing total thyroidectomy from 2016 to 2020. Clinical, biochemical, and pathological information was registered. We sought correlations between the different variables and the occurrence of post-operative hypocalcemia. This is a retrospective study carried out at a tertiary care teaching hospital. OBJECTIVES The aim of the study was to ascertain the incidence of hypocalcemia after thyroidectomy and to establish potential clinical and pathological risk factors for its development. RESULTS Three hundred and thirty-seven patients were included in this study (78% female), with a median age of 47 years. The majority (75%) harbored thyroid neoplasms. Post-operative hypocalcemia developed in 43 patients (12.7%). On bivariate analysis, the most significant risk factor was an intraoperative injury of the parathyroid glands (OR = 2.49, 95% CI = 1.11-5.59), followed by a surgical time > 2.5 h (OR = 2.0, 95% CI = 1.03-4.19), concomitant lymph node dissection (OR = 2.45, 95% CI = 1.2-4.9), and placement of drains (OR = 2.40, 95% CI = 1.19-4.87). Only parathyroid injury remained statistically significant on multivariable analysis. CONCLUSIONS The most significant risk factor for the development of post-operative hypocalcemia after thyroidectomy is injury of the parathyroid glands, which is usually noticed by the surgeon.

Abstract
Transoral Endoscopic Thyroidectomy Vestibular Approach (TOETVA) is a novel technique that allows the thyroid to be approached without visible scars, as it is performed through a natural orifice. It was first described and developed in Asia where due to sociocultural reasons neck scars are considered a stigma. This technique, as we now nowadays, and its preliminary results, were first reported by Angkoon Anuwong in August 2015 at the International Association of Endocrine Surgeons (IAES) world surgery congress held in Bangkok. Here we present the TOETVA approach, step-by-step, in order it could be safely replicated, aiming also it can be spread within the therapeutic framework of endocrine surgery. However, it is important to remark that, as happens in most of remote approaches, it is only suitable for a small percentage of patients.

Abstract
INTRODUCTION Hypoparathyroidism (HP) is the most common complication of total thyroidectomy and can be an emergency. OBJECTIVES To describe the prevalence of HP after total thyroidectomy in children under 14 years of age, the variables related to its appearance and its clinical expression. PATIENTS AND METHODS Retrospective study at a children's hospital in the last 20 years. HP was defined by the need to supplement calcium after the intervention and was considered permanent if it could not be suspended within 12 months. Fisher's statistical method of comparison of proportions. RESULTS Thirty-nine children and adolescents (26 females) with an age range of 3.67-14.00 years. In 25 patients, the intervention was prophylactic and in 14 it was therapeutic; 14 suffered accidental excision of some parathyroid gland, but none more than two of them; 12 presented HP, of which 3 were permanent; 5 presented clinical symptoms; 1 of them was an emergency. The frequency of HP was 4/4 when 2 parathyroids were dissected, 2/10 when one was dissected, and 6/25 when none were dissected (p = 0.02). In the prophylactic interventions, it was 6/25 compared to 6/14 in the therapeutic ones (p = 0.29). The three cases of permanent HP were in children under 6 years of age, and it did not occur in any older children (p = 0.09). CONCLUSIONS HP is a common and sometimes serious complication in children after total thyroidectomy. It can occur, and even be permanent, even if the intervention is prophylactic and parathyroid glands remain in situ. Younger age could be a risk factor.

Abstract
OBJECTIVE We aimed to study the predictive factors for recovery of parathyroid function in hypoparathyroid patients after total thyroidectomy for thyroid cancer. METHODS We designed a retrospective, multicentre and nation-wide analysis of patients with total thyroidectomy who were seen in twenty endocrinology departments from January to March 2018. We selected patients with histologically proven thyroid cancer and retrieved information related to surgical procedure and thyroid cancer features. Survival analysis and Cox regression analysis were used to study the relationship between these variables and the recovery of parathyroid function. RESULTS From 685 patients with hypoparathyroidism at discharge of surgery, 495 (72.3%) recovered parathyroid function over time. Kaplan-Meier analysis showed that this recovery was significantly related to the presence of specialized surgical team (P<0.001), identification of parathyroid glands at surgery (P<0.001), papillary histopathology (P=0.040), and higher levels of postoperative calcium (Ca) (P<0.001) and parathyroid hormone (PTH) (P<0.001). Subjects with gross extrathyroidal extension (P=0.040), lymph node metastases (P=0.004), and surgical re-intervention after initial surgery (P=0.024) exhibited a significant risk of persistence of hypoparathyroidism. Multivariate Cox regression analysis showed that the significant and independent factors for recovery of parathyroid function were postoperative concentrations of Ca (P=0.038) and PTH (P=0.049). The presence of lymph node metastases was a negative predictor of recuperation of parathyroid function (P=0.042) in this analysis. CONCLUSION In patients with thyroid cancer, recovery of parathyroid function after total thyroidectomy was directly related to postoperative Ca and PTH concentrations, and inversely related to lymph node metastases.

Abstract
OBJETIVO Determinar la utilidad del gasto urinario alto como predictor temprano de bajo costo para hipoparatiroidismo posoperatorio. MÉTODO Se realizó un estudio retrospectivo unicéntrico a 1 año en adultos sometidos a tiroidectomía total en The American British Cowdray Medical Center I.A.P., calculando el gasto urinario en 24 horas, utilizando valores de calcio sérico corregido por albúmina con una tabla de correlación e identificando a los pacientes que recibieron calcio suplementario en las primeras horas de posoperatorio. Se dividieron en pacientes con hipoparatiroidismo posoperatorio y con valores normales de calcio en el primer día, diferenciando a los que recibieron suplementación oral de calcio profiláctico. RESULTADOS Se estudiaron 47 pacientes, 19 (40%) en el grupo con hipocalcemia posoperatoria y 28 (59.5%) en el grupo sin hipocalcemia posoperatoria. La media de gasto urinario en las primeras 8 horas de posoperatorio fue mayor en el grupo de hipocalcemia posoperatoria en comparación con el grupo sin hipocalcemia, sin diferencia significativa (p = 0.392), y tampoco durante las primeras 16 horas (p = 0.435). CONCLUSIONES En nuestro estudio no existe relación entre el incremento del gasto urinario y la predicción de hipoparatiroidismo posoperatorio. Se necesitan estudios con muestras de mayor tamaño y con un diseño metodológico más fuerte (prospectivo) para determinar si en realidad la diferencia obtenida puede figurar como predictor. OBJECTIVE to determine the usefulness of high urine output as a low-cost early predictor for postoperative hypoparathyroidism.. METHOD A study was conducted inside The American British Cowdray Medical Center I.A.P. for a year in adult patients who underwent total thyroidectomy divided in two groups: those with post-surgical hypocalcemia and without post-surgical hypocalcemia using the 24-hour calcium levels. Urinary output of each patient was verified searching for the relation between this measurement and the probability of developing post-surgical hypoparathyroidism. RESULTS A total of 47 patients were studied, of whom 19 (40%) were classified with post-surgical hypocalcemia and 28 (59.5%) with no post-surgical hypocalcemia. The urinary output mean on the first 8 hours post-operatory was higher in the post-surgical hypocalcemia group in comparison with the group with no evidence of hypocalcemia, showing no significant difference (p = 0.392). Urinary output 16 hours post-surgical was no significant either (p = 0.435). CONCLUSIONS In our study, there was no relation found between the increase of the urinary output and the post-surgical hypoparathyroidism prediction. Further studies with a bigger sample and a stronger methodologic design (prospective) are needed to determine if the difference obtained may be useful as a predictor.

Abstract
Metastases to the thyroid gland are unusual, especially from a colorectal cancer. We present the case of an 85-year-old female with a history of colon cancer in 2004 treated with surgery, who 14 years later develop dysphonia and dysphagia associated to an elevation of carcinoembryonic antigen. A pathologic thyroid mass was evidenced in a positron emission tomography-computed tomography. The colorectal origin of the mass was confirmed with a biopsy. The patient received surgical treatment doing the right hemithyroidectomy. This entity must be suspected in patients with oncological history and a new thyroid nodule. Surgery is a therapeutic option with either curative or palliative intent.

Abstract
Thyroidectomy is the most frequent procedure in endocrine surgery. The conventional approach through a collar incision, as described by Kocher in XIXth century, has become the "gold standard". It is continuously evolving in spite of, many years ago, it showed to be safe and efficient with quality standards difficult to beat. Endoscopic and robotic surgery have developed "new approaches" to thyroid in order to improve the cosmetic results, looking even for invisible scars. We have done a thoughtful review of most of them trying to understand their benefits and drawbacks. Currently none of these "new approaches" have been shown to be better than conventional open thyroidectomy beyond offering a better cosmetic result. Besides, only a small percentage of patients can benefit of them. However, most of these approaches will remain if they treat the diseased thyroid and also improve the quality of life of our patients.

Abstract
There is controversy regarding the performance of preoperative laryngoscopy (LP) in thyroid surgery, with different recommendations being made, based on observational studies, in various publications. The aim of the study was to know the prevalence of laryngeal paralysis found in the LPs of patients who underwent thyroidectomy in benign and malignant pathology. A systematic review was carried out with 29 articles included for the qualitative study and a meta-analysis of 13 articles in which the data could be obtained to evaluate the same effect (in all patients in which an LP was carried out, those with preoperative laryngeal paralysis were included, and assigned to malignant or benign postoperative histology groups). The pooled prevalence of preoperative paralysis in benign pathology was 1.1% (95% CI 0.7 to 1.7%, 71% I2) and in 6.3% malignant pathology (95% CI 3.8 to 9.4%; I2 85%). The prevalence was significantly higher among patients with malignant pathology with an estimated effect RR 5.66, 95% CI, 2.48, 12.88. The studies analyzed present biases that will need to be corrected in future research, eliminating blinding biases in the selection and allocation of patients or in the laryngoscopy technique used. The LP in thyroid surgery evaluates possible disorders of laryngeal motility. The prevalence of laryngeal paralysis in thyroid pathology found in LPs in patients with a postoperative diagnosis of malignant pathology was higher than in the benign pathology group. This information is necessary for interpreting the intraoperative neuromonitoring signal and for making informed decisions.

Abstract
Hypoparathyroidism is the most common complication after total or completion thyroidectomy. It is defined as the presence of hypocalcemia accompanied by low or inappropriately normal parathyroid hormone (PTH) levels. Acute hypocalcemia is a potential lethal complication. Hypocalcemia treatment is based on endovenous or oral calcium supplements as well as oral calcitriol, depending on the severity of the symptoms. The risk of clinical hypocalcemia after bilateral thyroidectomy is considered very low if postoperative intact PTH decrease less than 80% with respect to preoperative levels. These patients could be discharged home without treatment, although this threshold may vary between institutions, and we recommend close surveillance in cases with increased risk (Graves disease, large goiters, reinterventions or evidence of parathyroid gland removal). Long-term treatment objectives are to control the symptoms and to keep serum calcium levels at the lower limit of the normal range, while preserving the calcium phosphate product and avoiding hypercalciuria.

Abstract
Objective To present our experience treating 38 patients with pediatric thyroid carcinoma. Method We received 44 pediatric patients with thyroid cancer between 2008 and 2016 in a specialized cancer center. A team of two surgeons treated all patients. We reviewed patient charts, treatment, pathology report, recurrence, and mortality. Qualitative variables were analyzed using Chi-square. Quantitative variables have a 95% confidence interval. Results 82% (n = 31) of cases were female. Average age at diagnosis was 12 years. The most frequent symptom was a thyroid nodule (74%), and the most frequent method of diagnosis was fine needle aspiration. 11 patients (29%) had pulmonary metastasis. All patients underwent total thyroidectomy, and 33 cases (86%) also had lymph node dissection. There were 5 (13%) postoperative complications. 33 cases received radioactive iodine treatment after surgery. Conclusions Pediatric thyroid cancer usually presents with multifocal disease. Female adolescents are affected more frequently than males. Differentiated thyroid cancer is the most frequent type, and it has excellent survival rates.

[PMID: 30032865 DOI: 10.1016/j.ciresp.2018.06.013] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2018] [Revised: 06/16/2018] [Accepted: 06/18/2018] [Indexed: 11/26/2022]
Abstract
In thyroid and parathyroid surgical procedures, good visibility of the thyroid gland is essential. This is traditionally achieved by means of traction sutures of the dermo-plastysmal flaps to the drapes of the operative field, producing tension and even damage to the skin. The Alexis® retractor ring improves exposure and facilitates stable access to the thyroid, protecting the skin from injury during the intervention.

Abstract
INTRODUCTION AND OBJECTIVES Radioiodine is the principal treatment for differentiated thyroid carcinomas. The aim of this study is to present our experience in the management of these tumours. MATERIAL AND METHOD We present a retrospective study of 55 patients operated for differentiated thyroid carcinoma in our hospital between 2007 and 2011. RESULTS The mean age at time of diagnosis was 49 years, and females predominated (78% of cases). Seventy eight percent of the patients were in the initial stages (stages i and ii). The definitive histopathological diagnosis was papillary carcinoma in 84% and follicular carcinoma in the remaining 16%. All of the patients, with the exception of 2 (4%), underwent total thyroidectomy, with lymphadenectomy in 58% of cases. Nine percent of the patients had permanent hypoparathyroidism and although 18% suffered transitory unilateral paralysis, 40% of these female patients had completely recovered after 6 months. Eighty-nine percent of the patients were given radioiodine postoperatively. There was a recurrence rate of 40% most of which was at cervical level (29% of the patients). Survival at 5 years was 87%, 95% of the papillary subtype, falling to 56% of the follicular subtype (P=.001). DISCUSSION/CONCLUSIONS The prognosis for differentiated thyroid carcinomas is excellent after appropriate surgical treatment, thorough preoperative assessment,and strict postoperative follow-up due to the significant recurrence rates.

Comparison of clinical characteristics of patients with follicular thyroid carcinoma and Hürthle cell carcinoma. ACTA ACUST UNITED AC 2018; 65:136-142. [PMID: 29433918 DOI: 10.1016/j.endinu.2017.12.006] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2017] [Revised: 10/28/2017] [Accepted: 12/01/2017] [Indexed: 11/16/2022]
Abstract
INTRODUCTION Hürthle cell carcinoma (HCC) is an uncommon thyroid cancer historically considered to be a variant of follicular thyroid carcinoma (FTC). The aim of this study was to assess the differences between these groups in terms of clinical factors and prognoses. PATIENTS AND METHODS A total of 230 patients (153 with FTC and 77 with HCC) with a median follow-up of 13.4 years were studied. The different characteristics were compared using SPSS version 20 statistical software. RESULTS Patients with HCC were older (57.3±13.8 years vs. 44.6±15.2 years; P<.001). More advanced TNM stages were also seen in patients with HCC and a greater trend to distant metastases were also seen in patients with HCC (7.8% vs. 2.7%, P=.078). The persistence/recurrence rate at the end of follow-up was higher in patients with HCC (13% vs. 3.9%, P=.011). However, in a multivariate analysis, only age (hazard ratio [HR] 1.10, confidence interval [CI] 1.04-1.17; P=.001), size (HR 1.43, CI 1.05-1.94; P=.021), and histological subtype (HR 9.79, CI 2.35-40.81; P=.002), but not presence of HCC, were significantly associated to prognosis. CONCLUSION HCC is diagnosed in older patients and in more advanced stages as compared to FTC. However, when age, size, and histological subtype are similar, disease-free survival is also similar in both groups.

Hypoparathyroidism following thyroidectomy: Predictive factors. ACTA OTORRINOLARINGOLOGICA ESPANOLA 2016; 68:106-111. [PMID: 27776803 DOI: 10.1016/j.otorri.2016.06.008] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2016] [Revised: 06/02/2016] [Accepted: 06/10/2016] [Indexed: 10/20/2022]
Abstract
OBJECTIVE To evaluate the incidence and predictive factors for transient and permanent hypocalcemia and hypoparathyroidism following thyroidectomy. METHOD We studied all the 162 patients that underwent thyroid surgery in the ENT department of the Centro Hospitalar Vila Nova Gaia/Espinho from January 2005 to December 2014. We reviewed pre-operative, 6h and 12h after surgery ionized calcium and PTH levels. All patients were reviewed and evaluated according to the following criteria: gender, age, thyroid function, histologic diagnosis of the specimen, surgery extension and presence or absence of hypoparathyroidism. RESULTS There were 31 (19.1%) cases of transient hypoparathyroidism and 8 (5%) of permanent hypoparathyroidism. No significant difference was found for transient hypoparathyroidism when patients were analyzed by gender. However, all cases of permanent hypoparathyroidism were observed in female individuals. Comparing hemithyroidectomy with all other surgical procedures, we found that extension of surgery was a great predictor of transient (p=0.0001) and permanent (p=0.001) hypoparathyroidism. Diagnosis of malignancy was a strong predictor of transient hypoparathyroidism (p=0.002). It was also associated with permanent hypoparathyroidism, although differences did not reach statistical significance (p=0.096). CONCLUSION Extension of surgery (total thyroidectomy) and diagnosis of malignancy are predictors of transient and permanent hypoparathyroidism.

Thyroid surgery at a volunteer program in Sub-Saharan Africa. Cir Esp 2016; 94:404-9. [PMID: 27402179 DOI: 10.1016/j.ciresp.2016.05.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2015] [Revised: 05/25/2016] [Accepted: 05/26/2016] [Indexed: 11/23/2022]
Abstract
INTRODUCTION The aim of this study is to demonstrate our experience at a volunteer surgical program in Cameroon, which is of special interest given to the inability to adopt international treatment guidelines for thyroid surgery in areas of limited resources due to the lack of preoperative testing and to the difficulty to obtain sustitutive hormonal treatment. METHODS This is a prospective observational study that includes 16 cases of thyroid surgery in Dschang (Cameroon) during June 2015. The patients were previously selected by a local medical team. All patients were black, 15 women and one man, with a mean age of 41 years. The surgical technique used for the removal of unilateral disease was hemithyroidectomy with isthmectomy and bilateral subtotal thyroidectomy for bilateral disease. RESULTS Five subtotal thyroidectomies, 9hemithyroidectomies and 2isthmectomies were performed. Prethyroid muscles were divided only in one case. We visualized 86% of the parathyroid glands and 84% of the recurrent laryngeal nerves. The main complications observed were one symptomatic cervical haematoma that required reoperation and 2surgical wound infections. There were no clinical episodes of hypocalemia or recurrent nerve lesion. The mean length of stay was 2.3 days. At follow-up, all bilateral thyroidectomies developed high TSH levels. CONCLUSIONS Thyroid surgery is safe in developing countries adopting protocols and techniques we use in our environment (avoiding total thyroidectomy). Bilateral thyroidectomies should not be performed unless functional studies are available in the follow-up and a thyroid hormone supplement stock guaranteed whenever necessary.

[Application of fibrin sealant in patients operated on for differentiated thyroid cancer. What do we improve?]. CIR CIR 2015; 84:282-7. [PMID: 26707252 DOI: 10.1016/j.circir.2015.02.004] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2015] [Accepted: 02/05/2015] [Indexed: 10/22/2022]
Abstract
BACKGROUND In recent years, several publications have shown that new adhesives and sealants, like Tissucol(®), applied in thyroid space reduce local complications after thyroidectomies. STUDY AIMS To demonstrate the effectiveness of fibrin glue Tissucol(®) in reducing the post-operative hospital stay of patients operated on for differentiated thyroid carcinoma in which total thyroidectomy with central and unilateral node neck dissection was performed (due to the debit drains decrease), with consequent cost savings. MATERIAL AND METHODS A prospective randomised study was conducted during the period between May 2009 and October 2013 on patients with differentiated thyroid carcinoma with cervical nodal metastases, and subjected to elective surgery. Two groups were formed: one in which Tissucol(®) was used (case group) and another where it was not used (control group). Patients were operated on by surgeons specifically dedicated to endocrine surgical pathology, using the same surgical technique in all cases. RESULTS A total of 60 total thyroidectomies with lymph node dissection were performed, with 30 patients in the case group, and 30 patients in control group. No statistically significant differences were observed in most of the studied variables. However, the case group had a shorter hospital stay than the control group with a statistically significant difference (p<0.05). CONCLUSION Implementation of Tissucol(®) has statistically and significantly reduced the hospital stay of patients undergoing total thyroidectomy with neck dissection, which represents a significant reduction in hospital costs. This decrease in hospital stay has no influence on the occurrence of major complications related to the intervention.

Primary papillary carcinoma in thyroglossal cysts. Case reports and literature review. ACTA OTORRINOLARINGOLOGICA ESPANOLA 2015; 67:102-6. [PMID: 26277736 DOI: 10.1016/j.otorri.2015.04.002] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2015] [Revised: 04/05/2015] [Accepted: 04/09/2015] [Indexed: 11/24/2022]
Abstract
The thyroglossal cyst can exceptionally appear as a primary cyst carcinoma. We discuss a series of 6 adult patients, assessed for long-lasting asymptomatic suprahyoid or lateral-to-larynx mass. The images showed a heterogeneous mass invading adjacent soft tissues. Fine needle aspiration biopsy did not contribute to diagnosis. We performed a Sistrunk procedure in all cases, 3 combined with total thyroidectomy and 1 with neck dissection. The postoperative course was favourable. No additional treatment was required, without evidence of recurrence in follow-up. The management is controversial due to the limited number of cases reported. Some classifications based on size and extent have been proposed to define the surgical treatment of such cysts.

Clinical Pathway for Thyroidectomy. Cir Esp 2015; 93:283-99. [PMID: 25732107 DOI: 10.1016/j.ciresp.2014.11.010] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2014] [Revised: 11/17/2014] [Accepted: 11/29/2014] [Indexed: 12/14/2022]
Abstract
Clinical pathways are care plans applicable to patient care procedures that present variations in practice and a predictable clinical course. They are designed not as a substitute for clinical judgment, but rather as a means to improve the effectiveness and efficiency of the procedures. This clinical pathway is the result of a collaborative work of the Sections of Endocrine Surgery and Quality Management of the Spanish Association of Surgeons. It attempts to provide a framework for standardizing the performance of thyroidectomy, the most frequently performed operation in endocrine surgery. Along with the usual documents of clinical pathways (temporary matrix, variance tracking and information sheets, assessment indicators and a satisfaction questionnaire) it includes a review of the scientific evidence around different aspects of pre, intra and postoperative management. Among others, antibiotic and antithrombotic prophylaxis, preoperative preparation in hyperthyroidism, intraoperative neuromonitoring and systems for obtaining hemostasis are included, along with management of postoperative hypocalcemia.

[Contribution of neuromonitoring to the safety of tracheal extubation after total thyroidectomy. Prospective study with needle electrodes]. REVISTA ESPANOLA DE ANESTESIOLOGIA Y REANIMACION 2013; 60:563-570. [PMID: 24050607 DOI: 10.1016/j.redar.2013.06.011] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/02/2013] [Revised: 06/18/2013] [Accepted: 06/24/2013] [Indexed: 06/02/2023]
Abstract
INTRODUCTION AND OBJECTIVES Bilateral laryngeal paralysis cause serious respiratory complications. In thyroid surgery, neuromonitoring helps in identifying the recurrent laryngeal nerve, reports on its functioning at the end of surgery, supports decision making, and may reduce the risk of bilateral paralysis. Our objective was to estimate the influence of neuromonitoring in operative strategy and extubation safety in total thyroidectomy. METHODS A non-randomized prospective study was conducted on 210 patients undergoing total thyroidectomy (420 laryngeal nerves stimulated included). We collected qualitative neuromonitoring variables (presence or absence of final signal after stimulation of the vagus nerve), and postoperative indirect laryngoscopy (normal motility or paralysis), performed until 3rd day after the surgery. RESULTS The accuracy of the test was 99.5% (95% CI 98.3 to 99.9). The positive predictive value was 100% (95% CI 99.1 to 100), which showed the high ability of neuromonitoring to predict paralysis in case of loss of signal, and the negative predictive value was 99.5% (95% CI 98.3 to 99.9), which indicated its predictive capacity for normal motility when there is a normal signal. CONCLUSIONS In our group of patients, recurrent laryngeal nerve monitoring was useful in total thyroidectomy as it provided information on the prognosis of laryngeal motility, and helped in making decisions during surgery when there was signal loss. Due to the risk of serious respiratory complications due to bilateral recurrent laryngeal nerve paralysis, we opted for the performing of the 2-stage total thyroidectomy in case of signal loss in the first lobectomy. Thereby, neuromonitoring contributed to the safety of the airway in tracheal extubation, aiding in the prevention of a possible bilateral laryngeal paralysis.

Best approach for posterior mediastinal goiter removal: transcervical incision and lateral thoracotomy. Arch Bronconeumol 2013; 50:255-7. [PMID: 24239133 DOI: 10.1016/j.arbres.2013.09.009] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2013] [Revised: 09/13/2013] [Accepted: 09/16/2013] [Indexed: 11/30/2022]
Abstract
Surgical removal of intrathoracic goiter can be performed by a cervical approach in the majority of patients. Review of literature shows that experienced surgeons need to perform an extracervical approach in 2-3% of cases. In spite of surgical management of substernal goiter is well defined, there is little available information about surgical approach of intrathoracic goiters extending beyond the aortic arch into the posterior mediastinum. We report two cases and propose combination of cervical incision and muscle-sparing lateral thoracotomy for posterior mediastinal goiter removal. In such cases, we do not favour sternotomy as posterior mediastinum is inaccessible due to the presence of heart and great vessels anterior to the thyroidal mass that would lead to perform a perilous blind dissection. Based in our experience, transcervical and thoracotomy approach is indicated for a complete and safe posterior mediastinal goiter removal.

Abstract
Recurrent laryngeal nerve injury remains one of the main complications in thyroid and parathyroid surgery. When this injury is bilateral, an acute upper airway obstruction may occur, leading to a potentially life-threatening situation for the patient. The visual identification of the nerve during surgery is the best way to preserve its integrity. However identification of the nerves by means of electromyographic stimuli through electrodes attached to endotracheal tubes could help in decreasing nerve injury. In these cases the experience and role of the anesthetist is essential to correctly place the electromyographic endotracheal tube and ensure that the electrodes are in touch with the vocal cords during the surgery. Moreover, the results of the electromyography can be affected by the neuromuscular blocking agents. Therefore, the choice and dose must be adapted, in order to ensure a suitable anesthetic depth, and adequate response.

Abstract
OBJECTIVE To analyse the potential advantages and outcomes of the new Harmonic Focus™ (Focus) device compared to the Harmonic Scalpel™ ACS-14C in benign thyroid surgery. METHODS A controlled randomised study was conducted in which the Focus was compared to former ACS-14C device in patients undergoing total thyroidectomy for multinodular goitre. The primary endpoint was time of surgery. The secondary endpoints were time of use of the device, number of ligatures, blood loss, hypocalcaemia, laryngeal nerve impairment, postoperative pain and quality of life. RESULTS Two groups of patients were included, 26 patients in group i (ACS-14C) and 28 in group ii (Focus). There was a 16% reduction in surgical time (78.7 ± 22.01 vs. 66 ± 17.0 min; P<.05) between group i and ii respectively. The Focus was used longer than ACE-14S, both in absolute time (26.0 ± 7.7 vs. 10.0 ± 3.5 minutes; P<.05), as well as in relative time (40.7 ± 11.8% vs. 13.1 ± 4.1%; P<.05), respectively. A significant reduction in number of ligatures in Focus patients was also observed (0,3 ± 0,8 vs. 2.9 ± 3.6; P<.05). Budget impact analysis showed an additional average savings per procedure of 179.74 €. CONCLUSIONS Focus ergonomics significantly improved the operation time in thyroidectomy causing a positive impact on the budget. Focus also adds further benefits to those previously achieved by Harmonic technology, and it is by itself more cost-effective in total thyroidectomy than ACS-14C.
