Bocio endotorácico / Endothoracic Goiter

Introducción: Un bocio se considera intratorácico cuando más de un 50 por ciento de la glándula tiroides está en el mediastino, o sea, por debajo del nivel del estrecho torácico superior. Se trata de una enfermedad poco frecuente que padece aproximadamente el 3 por ciento de los pobladores del mundo. La incidencia del bocio nodular ha disminuido debido a la ingestión en algunos países de sal yodada y alimentos ricos en yodo. Esta enfermedad alcanza alrededor del 10 por ciento de las masas mediastínicas. Objetivo: Presentar el caso de un paciente masculino, operado de bocio endotorácico en la provincia de Cienfuegos. Presentación de caso: Se presenta un paciente masculino, de 48 años de edad, que acude a consulta y refiere aumento de volumen del cuello en la región anterior, que se acompaña de decaimiento y en ocasiones disfagia tanto a los alimentos líquidos como a los sólidos. Además, refiere ligera disnea que tolera adecuadamente cuando realiza las actividades de la vida diaria. Por tratarse de una enfermedad poco frecuente, se considera de interés científico publicar el caso para conocimiento de los profesionales dedicados al estudio y tratamiento de las afecciones tiroideas. Conclusiones: El bocio endotorácico es una entidad poco frecuente y en todos los casos requiere de intervención quirúrgica(AU)

Introduction: A goiter is considered intrathoracic when more than 50 percent of the thyroid gland is in the mediastinum; in other words, below the level of the superior thoracic outlet. It is a rare disease that affects approximately 3 percent of the world's population. The incidence of nodular goiter has decreased due to the ingestion of iodized salt and iodine-rich foods in some countries. This disease accounts for about 10 percent of mediastinal masses. Objective: To present the case of a male patient operated on for endothoracic goiter in the province of Cienfuegos. Case presentation: The case is presented of a 48-year-old male patient who comes for consultation referring a volume increase in the anterior neck region, accompanied by decay and sometimes dysphagia to both liquid and solid food. In addition, he reports slight dyspnea that he tolerates adequately when performing daily living activities. Since this is a rare disease, it is considered of scientific interest to publish the case for the knowledge of professionals dedicated to studying and treating thyroid disorders. Conclusions: Endothoracic goiter is a rare entity and, in all cases, requires surgical intervention(AU)

Surgical management of goiter with intrathoracic extension at the Philippine General Hospital Department of Otolaryngology Head and Neck Surgery

Objective@#To describe the demographic and clinical characteristics of patients diagnosed with intrathoracic thyroid masses managed surgically in our institution, determine associated factors affecting eventual operative approaches for these patients, and assess postoperative outcomes and complications associated with surgical intervention.@*Methods@#Design: Retrospective descriptive case series. Setting:Tertiary National University Hospital. Participants: 24 patients.@*Results@#The mean age of patients diagnosed with intrathoracic goiters was 55.71 years old, with a 1:1.4 male to female ratio; with most having an intrathoracic extent of Huins Grade 1 (67%) compared to others having Huins Grade 2-3. Majority of patients pre-operatively had a Fine Needle Aspiration (FNA) Bethesda Thyroid Nodule Classification of Category II (benign); 79% of total patients underwent excision of thyroid mass utilizing a transcervical approach alone. As Intrathoracic Extension (ITE) grade increased, additional transthoracic approaches were performed; duration of operation, average estimated blood loss, length of hospital stay was also noted to increase. Majority of post operative surgical histopathology results revealed malignant thyroid masses, in contrast to pre-operative FNA. Post-operative transient hypocalcemia was the most reported immediate complication. @*Conclusions@#Management of intrathoracic goiter is often multidisciplinary. Referral to the thoracic vascular service is warranted for access to the thoracic inlet. Classification by grade of intrathoracic goiters is helpful to determine the most appropriate operative approach and may be predictive of intraoperative and postoperative outcomes. Postoperative histopathology across all ITE grades mostly yield malignant results; hence, preoperative FNA results should be used with caution.

Bocio endotorácico en un adulto / Endothoracic goiter in an adult

Se presenta el caso clínico de un paciente de 48 años de edad, quien acudió a la consulta de Patología de Tiroides del Hospital Provincial Dr. Gustavo Aldereguía Lima de Cienfuegos, por presentar aumento de volumen del cuello en la región anterior, decaimiento, ocasionalmente disfagia y ligera disnea. Al examen físico se constató un tumor en la región anteroinferior y lateral derecha del cuello, movible, que se prolongaba hacia abajo a la parte superior del tórax. Se realizó hemitiroidectomía derecha con exéresis de la prolongación endotorácica. El paciente evolucionó favorablemente.

The case report of a 48 years patient is presented. He went to the Thyroid Pathology Service of Dr. Gustavo Aldereguía Lima Provincial Hospital from Cienfuegos, due to an increase of volume in the anterior region of the neck, weakness, occasionally deglutition disorders and light dyspnea. A tumor was verified in the anteroinferior and lateral right region of the neck, movable, that was prolonged downward to the superior part of the thorax when the physical exam was carried out. A right hemithyroidectomy was carried out with exeresis of the endothoracic extension. The patient had a favorable clinical course.

Goitre plongeant Particularités cliniques et thérapeutiques / Sub-sternal goitre: Clinical and therapeutic features

Etudier les caractéristiques cliniques, radiologiques et thérapeutiques des goitres plongeants et établir un arbre décisionnel de prise en charge Méthodes: Nous rapportons une étude rétrospective portant sur 67 cas de goitre plongeant colligés sur une période de 27 ans entre 1990 et 2016. Résultats: L'âge moyen des patients était de 53 ± 15,1 ans et le sex-ratio de 0,24. La tuméfaction basicervicale antérieure était le motif de consultation le plus fréquent, rapportée dans 82% des cas associée à des signes de compression dans 31% des cas. Une paralysie récurrentielle unilatérale a été objectivée dans quatre cas. Une radiographie de thorax a montré une opacité médiastinale dans 75% des cas et une déviation trachéale dans 85% des cas. Un scanner cervico-thoracique pratiquée dans 73% des cas a confirmé le diagnostic en objectivant cinq prolongements dépassant la crosse de l'aorte. Le traitement chirurgical était mené par voie cervicale dans 99% des patients et une sternotomie a été réalisée devant l'échec d'extraction par cervicotomie. Une paralysie récurrentielle postopératoire a été observée dans un cas et l'hypoparathyroïdie définitive a été rapportée chez six malades avec un recul moyen de trois ans. Conclusion: Les goitres plongeants sont devenus rares en Tunisie du fait de la prise en charge plus précoce des nodules thyroïdiens. Le scanner cervico-thoracique représente le gold standard pour l'étude et la confirmation du diagnostic du goitre plongeant ainsi que pour l'attitude thérapeutique. L'indication chirurgicale est toujours impérative devant le risque vital qu'il pose.

Surgical management of intrathoracic goiters: 20 years experience

Background: Surgery is necessary for intrathoracic goiters (ITG) even in asymptomatic forms considering the risks of compression and malignancy. The major problem is the adequate approach.  Intrathoracic goiter’s removal can be performed via a cervical approach, whereas sternotomy might be required intraoperatively in some cases.Methods: A retrospective analysis of twenty years on 122 cases of intrathoracic goiters in a referral centre for thoracic surgery was carried out.  We included secondary substernal goiters and ectopic thoracic goiters.Our aim was to define the specifities of this surgery and its outcomes. Postoperative data were examined as well as morbidity and mortality factors.Results: The most common symptoms included dyspnea, cough and dysphagia. Whereas Twenty-two patients were asymptomatic. One hundred sixteen patients underwent a successful transcervical incision without thoracic approach. Six cases of primary goiters were noted, of whom 3 were extracted via a cervical approach. Two cases showed unilateral recurrent nerve paralysis and two cases a hypoparathyroidism.Conclusions: Surgical management of intrathoracic goiter was correlated with low morbidity and mortality The cervical approach was performed in the vast majority of cases without an extra cervical procedure.  Intrathoracic approaches were restricted to some selected indications.

Substernal Goiter: a case to remember

SUMMARY Goiter is a localized or generalized thyroid hypertrophy. It can remain within the cervical region or grow down until it invades the mediastinum. The signs and symptoms depend on the size and location of the goiter. Although drugs and radioactive iodine are often used to treat thyroid disease, the presence of symptomatic substernal goiter is a clear indication for surgery. Death or postoperative complications rarely occur. We present a case of a 71-year-old man with recurrent thyroid pathology in the form of substernal goiter and hyperthyroidism even after partial thyroidectomy. The importance of this relates to the clinical evolution, volume, and location of the goiter as well as the surgical and pharmacological approach.

RESUMO O bócio é a hipertrofia da glândula tiroide localizada ou generalizada. Esta pode localizar-se na região cervical ou crescer através do mediastino. Os sinais e sintomas dependem do tamanho e da localização do bócio. Embora os fármacos e o iodo radioativo sejam frequentemente usados para tratar doenças tireoidianas, a presença do bócio subesternal sintomático é uma clara indicação para a cirurgia. A morte ou complicações pós-operatórias são raras. Apresentamos o caso de um homem de 71 anos com recorrência de patologia tireoidiana sob a forma de bócio subesternal e hipertireoidismo após tireoidectomia parcial. A importância desse caso relaciona-se com a evolução clínica, o volume e a localização do bócio e a abordagem cirúrgica e farmacológica desse tipo de patologia.

Substernal goiter and laryngopharyngeal reflux

ABSTRACT Objective This study aims to compare the prevalence of laryngopharyngeal reflux signs between two groups of patients undergoing thyroidectomy for voluminous goiter: substernal goiters and voluminous cervical goiter without thoracic extension. Subjects and methods A retrospective case-control study was performed with data retrieved of the charts of the patients submitted to thyroidectomies occurred at a tertiary care center (Head and Neck Surgery Department, University of São Paulo Medical School) between 2010 and 2014. The selected thyroidectomies were allocated in two groups for study: patients with substernal goiters and patients with voluminous cervical goiter without thoracic extension. Cervical goiters were selected by ultrasonography mensuration. Clinical criterion was used to define substernal goiter. Results The average thyroid volume in patients with substernal goiter was significantly greater than the average volume in patients with only cervical goiter (p < 0.001). The prevalence of signs of reflux laryngitis at laryngoscopy was significantly greater in substernal goiter patients (p = 0.036). Moreover, substernal goiter was considered as the unique independent variable for high reflux laryngitis signs at laryngoscopy (OR = 2.75; CI95%: 1.05-7.20; p = 0.039) when compared to only cervical goiter patients. Conclusion This study shows a significant association between substernal goiters and signs of laryngopharyngeal reflux at preoperative laryngoscopy. Therefore, when compared with voluminous cervical goiters, the substernal goiters increase the chance of reflux laryngitis signs in patients.

Assessment and surgical treatment for 58 substernal goiter / 中华耳鼻咽喉头颈外科杂志

Objective@#To investigate the diagnosis and treatment of substernal goiter.@*Methods@#A total of 58 cases with substernal goiters undergoing surgery between January 2005 and December 2015 were analysed retrospectively. There were 10 males and 48 females and their age ranged from 38 to 82 years with a median age of 58 years. According to enhanced CT and clinical signs of substernal goiters, there were 40 cases for typeⅠ, 17 cases for type Ⅱ, and 1 case for type Ⅲ.@*Results@#Patients with typeⅠand Ⅱ substernal goiters (8 cases of papillary carcinoma) underwent low neck and collar-type incision, and patients with type Ⅲ substernal goiters received carotid chest surgery. The use of harmonic scalpel in sternal goiter surgery provided with clearer surgical field, less bleeding. All the operations were successful, and recurrent laryngeal nerve was visually identified in all patients. Postoperative complications included trachyphonia (2 cases), without difficult breathing and tracheal stenosis.@*Conclusions@#Enhanced CT is the best means of preoperatively assessment of substernal goiter. It is feasible to treat patients with typeⅠand Ⅱ substernal goiters by lower neck and collar-type incision. Use of harmonic scalpel in substernal goiter surgery can reduce operation time and bleeding.

Necessity of Bone Wax Stanching Bleeding at Sternal Edge in Patients With Cardiac Surgery by Median Sternotomy / 中国循环杂志

Objective: To explore the necessity for application of bone wax stanching bleeding at sternal edge in cardiac surgery by median sternotomy. Methods: A total of 445 patients who receive cardiac surgery by the same surgeon performing median sternotomy in our hospital from 2011-01 to 2014-12 were studied. According to application of bone wax stanching bleeding, the patients were divided into 2 groups: Bone wax group,n=210 and Non-bone wax group,n=235. Re-thoracotomy for hemostasis, 12 h, 24 h and total draining volume after the operation and time of closing incision were compared between 2 groups. Results: There were 2 patients and 1 patient received re-thoracotomy for hemostasis in Bone wax group and Non-bone wax group respectively, which was not related to bone marrow cavity bleeding. In Bone wax group and Non-bone wax group, the draining volume at 12 h post-operation were (451 ± 240) ml vs (483 ± 238) ml, at 24 h post-operation were (615 ± 304) ml vs (639 ± 285) ml and the total volume were (842 ± 467) ml vs (842 ± 364) ml, allP>0.05; the time of closing incision were (68.0 ± 23.0 ) min vs (66.0 ± 19.0 ) min,P>0.05; the total transfusion rates were 21% vs 19%,P>0.05. Conclusion: Application of bone wax at sternum edge could neither affecting the drainage nor the speed of closing incision in cardiac surgery and therefore, it might be given up.

Combined Cervical and Video-Assisted Thoracoscopic Approch for Huge Substernal Goiter

Substernal goiter is defined as a thyroid mass of which more than half is located below the thoratic inlet. Substernal goiters must be removed surgically due to relation to compressive symptoms, potential airway compromise, and the possibility of an association with malignancy. Thyroidectomy for substernal goiter is usually carried out through a standard cervical approach. However, a few patients with various factors require an extracervical approach, usually by sternotomy. Recently, we successfully removed a substernal goiter that extended to the lower level of the aorta and tracheal carina though the combined cervical and video-assisted thoracoscopic approach. We present this case with a review of the literature.

Surgical treatment of substernal goiter : analysis of 102 patients / 中华普通外科杂志

Objective To summarize surgical experience for the treatment of substernal goiter.Methods 102 cases of substernal goiter underwent surgical resection,in 74 by low collar incision,12 cases by larger low collar incision and pillowing the shoulder pad about 20 degrees for neck hyperextension,8 cases by unilateral or bilateral infrahyoid muscles transection,8 cases by low collar and up-mid-sternal incision plus horizontal sawing in 2 and 3 ribs.Results Resection was performed successfully in all cases.Hoarseness occurred in 7 cases,4 cases recovered after one month,3 cases did not improve because of tumor invasion of laryngeal recurrent nerve.Postoperative transient hypocalcemia in 9 cases recovered after 2 to 3 months.102 patients were followed up for 1 to 3 years without recurrence.Conclusions Substernal goiter can be resected successfully through a transcervical approach or mid-sternal incision.CT scanning and chest X radiograph are decisive for the surgical approach.

Bocio intratorácico / Intra-thoracic goiter

Introducción: el bocio constituye la afección de la glándula tiroides que más es tratado en los servicios quirúrgicos, sin embargo, su posición anómala no es frecuente. Presentación de caso: paciente de 51 años de edad, con antecedentes de asma bronquial. Hace 3 años presentó un aumento de volumen de la región lateral izquierda del cuello y presencia de decaimiento, palpitaciones y disfagia ocasional, para lo cual llevó el tratamiento con levotiropsina sódica. Se indicaron estudios de la función tiroidea, radiografías de tórax (vista anteroposterior), ecografía de la tiroides y biopsia por aspiración con aguja fina. A través de la vía cervical se le realizó la tiroidectomía total corroborando que más del 50% de la glándula estaba en posición intratorácica, nódulos en ambos lóbulos y sin complicaciones; resultó ser un bocio coloide multinodular. Conclusiones: el bocio intratorácico responde poco al tratamiento médico, de preferencia se utiliza la tiroidectomía total por vía cervical ante síntomas de compresión siempre que sea posible.

Introduction: goiter constitutes the most treated condition of thyroid gland in surgical services, even though its anomalous position is not frequent. Case report: a 51 year-old patient with history of bronchial asthma. Three years ago the patient presented growth of volume of the lateral-left region of neck and presence of weakness, palpitations and occasional dysphagia, being treated with levothyroxine sodium. Studies of thyroidal function, thoracic radiographies (anteroposterior view), thyroid echography and fine needle aspiration biopsy were performed. Through the cervical line, total thyroidectomy was performed, confirming that more than 50% of the gland was in intra-thoracic position, there were nodules in both lobules without complications; it was a multinodular colloid goiter. Conclusions: intra-thoracic goiter has not a good response to medical treatment; when symptoms of compression are present, total thyroidectomy by cervical line is preferred whenever possible.

Relato de caso de bócio mergulhante (BM) em idosa com longa história de bócio nodular tóxico (BNT) e que evoluiu com insuficiência respiratória aguda enquanto aguardava cirurgia eletiva para extirpação do bócio. A evolução das complicações respiratórias dessa paciente sugere que o tratamento cirúrgico do BM em idosos deveria ser feito o mais breve possível, após o surgimento de sintomatologia respiratória, para evitar complicações.

Case report of substernal thyroid goiter in an elderly woman with long record of toxic nodular goiter that progressed to acute respiratory insufficiency while waiting for elective surgery for extirpation of goiter. The development of respiratory complications suggests that the surgical treatment of substernal thyroid goiter affecting elderly people should be pursuit as soon as possible after the appearance of respiratory symptomatology as a means of avoiding complications.

A Case of Minimally Invasive Cardiac Surgery by the Small Right Intercostal Thoracotomy for Left Atrial Myxoma after Substernal Reconstruction of the Esophagus / 日本心臓血管外科学会雑誌

We report a case of minimally invasive cardiac surgery treated by small right intercostal thoracotomy for left atrial myxoma after substernal reconstruction of the esophagus using gastric interposition. This technique could not only alleviated risk at the second median sternotomy, but was also minimally invasive. A 63-year old man was admitted to our hospital for complaints of right upper limb asthenia and slight fever. Computed tomography showed cerebral infarction. Moreover, cardiac ultrasonography showed a giant myxoma in the left atrium. We thought that it was impossible to reperform median sternotomy, because there was high risk of injury to the reconstructed esophagus using a gastric duct behind the sternum. The patient underwent excision of the myxoma by the right intercostal thoracotomy approach, and did well. He was discharged from the hospital without any complications.

Avaliação crítica de 33 pacientes com bócio mergulhante tratados cirurgicamente por cervicotomia / A critical analysis of 33 patients with substernal goiter surgically treated by neck incision

A possibilidade de ser necessário um acesso combinado, com uma incisão cervical e outra torácica, torna o tratamento do bócio mergulhante um desafio tanto no pré quanto no intra-operatório. Discutimos uma padronização da técnica cirúrgica para minimizar a necessidade da abordagem torácica, tornando o bócio mergulhante uma patologia tratável cirurgicamente, por uma única incisão cervical, e com baixos índices de complicações. OBJETIVO: Avaliar a abordagem cirúrgica do bócio mergulhante por cervicotomia e analisar as complicações cirúrgicas. MATERIAL E MÉTODOS: Foi realizada uma coorte histórica com corte transversal por análise retrospectiva dos prontuários de pacientes submetidos à tireoidectomia no período de maio de 2002 a julho de 2007. Um total de 316 pacientes foi submetido à tireoidectomia sendo 33 (10,4 por cento) por bócio mergulhante. RESULTADOS: Todos os 33 pacientes foram tratados cirurgicamente por via cervical sem necessidade de esternotomia. Não foram observadas lesões definitivas de nervo laríngeo inferior ou hipoparatireoidismo definitivo. Apenas 2 pacientes apresentaram paresia de nervo recorrente e 2 pacientes foram reabordados por hematoma cervical. CONCLUSÃO: Pacientes com bócio mergulhante podem ser tratados cirurgicamente por uma única incisão cervical com segurança e baixos índices de complicação.

The possibility of needing a combined access, with neck and chest incisions makes the treatment of substernal goiter a challenge both in the pre-op and the intraoperative. We hereby, discuss a standardization of the surgical technique to minimize the need for a chest approach, making the substernal goiter a surgically treatable disease, through a single neck incision, and with low indices of complication. AIM: to assess the substernal goiter surgically approach through a neck incision and to analyze the surgical complications. MATERIALS AND METHODS: we carried out a historical cohort by retrospective analysis of the charts of patients submitted to thyroidectomy, and 33 of them (10.4 percent) had substernal goiter. RESULTS: all 33 patients were surgically treated through a neck incision without the need for sternotomy. We did not observe definitive lesions in the inferior laryngeal nerve or definitive hypoparathyroidism. Only 2 patients had recurrent nerve paresis; and 2 patients were re-operated because of a neck hematoma. CONCLUSION: patients with substernal goiter can be safely treated surgically through a single neck incision, bearing low complication rates.

A study of comparison between small incision of cardiac operation and regular incision / 中国医师进修杂志

Objective To guide clinical operation,the invasion,efficacy,convalescence by different operating ways on cardiac surgery were studied.Methods Left axillary minithoracotomy was applied to 41 patients with ductus atteriosus(A group);right axillary minithoracotomy was applied to 46 patients with atrial soptal defect (ASD),ventricular septal dofect(VSD),triple-symptom complex of Fallot(C group);49 patients with replacement of valvular heart,VSD,ASD,totralogy of Fallot,left atrial myxoma were operated in substernal segment minithoracotomy (D group).The comparison between above groups and the regular left chest posterolateral operation on 42 patients (B group) and the sternal median operation on 77 patients (E group)was carried out.Results (1) A group had such advantages as the operation time,hemorrhage volume,hospital day,compared with B group [(38±13) min vs (64±14) min,(17±12) ml vs (200±100) ml,(6±2) d vs(11±3) d,respectively](P<0.01).(2) There were difference in extra corporeal circulation time,bemorrhage volume and hospital day between C group and E group[(39±8) min vs (68±8)min,(150±150) ml vs (700±300)ml,(8±3)d vs(12±4)d,respectively](P<0.01 or <0.05).There were difference in hemorrhage volume,fluence between D group and E group (P<0.05).Conclusion Small incision,slight trauma,less hemorrhage,slight ache,quick recovery,concealed incision and so on are characteristic of the left subaxillary minithoracotomy for ligation of ductus arteriosus,the right subexillary minithoracotomy for opening heart operation with heart beating and the substernal segment minithoracotomy for opening heart operation with extra corporeal circulation.
