ABSTRACT

Objective:To quantitatively evaluate the risk of recurrence in patients with secondary hyperparathyroidism after parathyroidectomy. Methods:The clinical data of 168 patients who underwent parathyroidectomy(PTX) from June 2017 to May 2019 were collected. The prediction model was constructed by using Akaike information criterion(AIC) to screen factors. A total of 158 patients treated with PTX from June 2019 to September 2021 were included in the validation set to conduct external validation of the model in three aspects of differentiation, consistency and clinical utility. Results:The prediction model we constructed includes different dialysis methods, ectopic parathyroid gland, the iPTH level at one day and one month after surgery, the number of excisional parathyroid and postoperative blood phosphorus. The C index of external validation of this model is 0.992 and the P value of the Calibration curve is 0.886[KG0.5mm]1. The decision curve analysis also shows that the evaluation effect of this model is perfect. Conclusion:The prediction model constructed in this study is useful for individualized prediction of recurrence after PTX in patients with secondary hyperparathyroidism.

ABSTRACT

El hiperparatiroidismo primario es el tercer trastorno endocrino más común, alrededor del 85% de los casos se debe a adenomas paratiroideos. El tratamiento definitivo es la paratiroidectomía, siendo la causa más común de fracaso la resección inadecuada y la localización de tejido ectópico, representando un desafío para el cirujano. En el presente trabajo se presenta el caso de un paciente con diagnóstico de adenoma paratiroideo mediastínico gigante, siendo este el de mayor longitud descrito en la literatura en los últimos 10 años. Caso clínico: Paciente masculino de 70 años de edad quien consulta por presentar convulsiones, polidipsia y poliuria. Se determinan niveles elevados de PTH, hipercalcemia e hipofosfatemia. Estudios de imagen describen lesión alargada localizada en espacio paratraqueal derecho extendiéndose hasta el polo inferior de lóbulo tiroideo derecho. Se decide resolución quirúrgica, mediante la realización de cervicotomía y toracoscopia con evolución satisfactoria del paciente. Conclusión: Los adenomas paratiroideos ectópicos constituyen una causa común de falla quirúrgica e hiperparatiroidismo persistente, su sospecha es de gran importancia. El tratamiento definitivo es la cirugía. La localización preoperatoria por pruebas de imagen es fundamental para seleccionar correctamente la técnica quirúrgica y garantizar el éxito de la cirugía. El abordaje cervical y toracoscópico es una alternativa segura y eficaz(AU)


Primary hyperparathyroidism is the third most common endocrine disorder, about 85% of cases are due to parathyroid adenomas. The definitive treatment is parathyroidectomy, being the most frequent cause of failure the inadequate resection and the location of ectopic tissue. The ectopic parathyroid adenomas represent a challenge for the surgeon. In this paper a case of a patient diagnosed with giant mediastinal parathyroid adenoma is presented, and is the largest reported in the literature in the last 10 years. Clinical case: 70-year-old male patient presented with seizures, polydipsia and polyuria, reason for which he consults. Elevated PTH levels, hypercalcemia, and hypophosphatemia are determined. Imaging studies report an elongated lesion located in the right paratracheal space that extends to the lower pole of the right thyroid lobe. Surgical resolution was decided, by performing cervicotomy and thoracoscopy with satisfactory recovery of the patient. Conclusion: Ectopic parathyroid adenomas are a common cause of surgical failure and persistent hyperparathyroidism; their suspicion is of great importance. The definitive treatment is surgery. Preoperative localization through imaging tests is essential to correctly select the surgical technique and guarantee the success of the surgery, the cervical and thoracoscopic approach is a safe and effective alternative(AU)

ABSTRACT

Resumen Introducción: A pesar de que el carcinoma de paratiroides es uno de los cánceres menos frecuentes del mundo, es importante tenerlo en cuenta al plantear el diagnóstico diferencial del hiperparatiroidismo primario, ya que su diagnóstico temprano tiene repercusiones en el tratamiento y el pronóstico vital del paciente. Caso Clínico: A continuación, se expone un caso clínico de un paciente con sintomatología abigarrada de hiperfunción paratiroidea que, dada la sospecha clínica de carcinoma de paratiroides y la no infiltración de estructuras adyacentes, fue tratado con una paratiroidectomía. Conclusión: Esta cirugía supone una menor morbilidad, sin suponer un detrimento para la supervivencia global del paciente.


Introduction: Parathyroid carcinoma should be taken into consideration among the differential diagnosis of primary hyperparathyroidism, even though it is one of the less common malignant tumours in the world, because an early diagnosis is essential for the treatment and the prognosis of the patient. Case Report: We present the case of a patient whose symptoms were compatible with hyperfunction of parathyroid gland. Due to the malignant disease suspicion and the non-invasion of adjacent tissue, he was treated with a parathyroidectomy. Conclusión: This type of treatment supposes a lower morbidity without decrease in overall survival, according to bibliography.

ABSTRACT Background: Kocher's cervicotomy has been the classic approach for thyroid and parathyroid surgery. The greater concern about neck scarring has generated an increasing interest in reducing scar size or leaving the scar in less visible places. In 2016 Anuwong published 60 cases of TOETVA/TOEPVA with optimal outcomes. Objectives: The aim of this study is to report the initial experience with transoral endoscopic thyroidectomy and parathyroidectomy vestibular approach in Hospital Universitario Austral. Material and methods: We conducted a retrospective analysis of 18 prospective procedures performed between May 2019 and March 2020. The procedures performed were 2 parathyroidectomies, 13 lobectomies, 4 total thyroidectomies, 1 with central lymph node dissection; one patient presented a parathyroid adenoma and a benign thyroid nodule. Cytology report according to the Bethesda system: category II in 7 cases, VI in 9 and indeterminate in 1. Results: 18 female patients. Median age: 41 years. Mean nodule size: 30 mm. Mean gland volume: 24 mL. Conversion. 1 case. Mean operative time: lobectomy, 260 minutes; total thyroidectomy, 262 minutes. Definite histology: papillary thyroid carcinoma,11; benign nodular goiter, 6; parathyroid adenoma, 2. Complications: mild ecchymosis, 12 patients; temporary hyperparathyroidism, 1 case; temporary recurrent laryngeal palsy, 1 case; temporary numbness of the mental region in 1 case. In the two cases undergoing total thyroidectomy due to cancer, thyroglobulin level 6 weeks after surgery was < 0.1 μIU/mL. Conclusions: 1) The transoral approach is a safe and feasible procedure that offers excellent cosmetic results. 2) It can be implemented using conventional endoscopic equipment, has a short learning curve and low morbidity rate. 3)It constitutes an alternative for the treatment of low-risk papillary thyroid carcinoma. 4) Patient's safety should be guaranteed.

ABSTRACT

Abstract Introduction: Some authors advise in favor of delayed sampling of intraoperative parathormone testing (ioPTH) during parathyroidectomy in dialysis and kidney-transplanted patients. The aim of the present study was to evaluate the intensity and the role of delayed sampling in the interpretation of ioPTH during parathyroidectomy in dialysis patients (2HPT) and successful kidney-transplanted patients (3HPT) compared to those in single parathyroid adenoma patients (1HPT). Methods: This was a retrospective study of ioPTH profiles in patients with 1HPT, 2HPT, and 3HPT operated on in a single institution. Samples were taken at baseline ioPTH (sampling at the beginning of the operation), ioPTH-10 min (10 minutes after excision of the parathyroid glands), and ioPTH-15 min (15 minutes after excision of the parathyroid glands). The values were compared to baseline. Results: Median percentage values of ioPTH compared to baseline (100%) were as follows: 1HPT, ioPTH-10 min = 20% and ioPTH-15 min = 16%; 2HPT, ioPTH-10 min = 14% and ioPTH-15 min = 12%; 3HPT, ioPTH-10 min = 18% and ioPTH-15 min = 15%. Discussion: The reduction was equally effective at 10 minutes in all groups. In successful cases, ioPTH decreases satisfactorily 10 minutes after parathyroid glands excision in dialysis and transplanted patients, despite significant differences in kidney function. The postponed sampling of ioPTH appears to be unnecessary.


Resumo Introdução: Alguns autores aconselham a favor de se fazer uma amostragem tardia de teste de paratormônio intraoperatório (PTHIO) durante paratireoidectomia em pacientes transplantados renais e em diálise. O objetivo do presente estudo foi avaliar a intensidade e o papel da amostragem tardia na interpretação do PTHIO durante paratireoidectomia em pacientes em diálise (2HPT) e pacientes com transplante renal bem sucedido (3HPT) em comparação com aqueles em pacientes com adenoma único de paratireoide (1HPT). Métodos: Este foi um estudo retrospectivo dos perfis de PTHIO em pacientes com 1HPT, 2HPT, e 3HPT operados em uma única instituição. Foram coletadas amostras de PTHIO basal (amostragem no início da operação), PTHIO-10 min (10 minutos após a excisão das glândulas paratireoides), e PTHIO-15 min (15 minutos após a excisão das glândulas paratireoides). Os valores foram comparados aos resultados basais. Resultados: Os valores percentuais medianos do PTHIO em comparação aos basais (100%) foram os seguintes: 1HPT, PTHIO-10 min = 20% e PTHIO-15 min = 16%; 2HPT, PTHIO-10 min = 14% e PTHIO-15 min = 12%; 3HPT, PTHIO-10 min = 18% e PTHIO-15 min = 15%. Discussão: A redução foi igualmente eficaz aos 10 minutos em todos os grupos. Em casos de sucesso, o PTHIO diminui satisfatoriamente 10 minutos após a excisão das glândulas paratireoides em pacientes em diálise e transplantados, apesar das diferenças significativas na função renal. A amostragem tardia de PTHIO parece ser desnecessária.

ABSTRACT

Parathyroid carcinoma is a rare malignant disease that presents as a sporadic or familial primary hyperparathyroidism (PHP). The latter is associated with some genetic syndromes. It occurs with equal frequency in both sexes, unlike PHP caused by parathyroid adenoma that is more common in women. It should be suspected in cases of severe hypercalcemia, with high parathyroid hormone levels and a palpable cervical mass. Given the difficulty in distinguishing between parathyroid carcinoma and adenoma prior to the surgery, the diagnosis is often made after parathyroidectomy. The only curative treatment is complete surgical resection with oncologic block resection of the primary tumor to ensure free margins. Adjuvant therapies with chemotherapy or radiation therapy do not modify overall or disease-free survival. Recurrences are common and re-operation of resectable recurrent disease is recommended. The palliative treatment of symptomatic hypercalcemia is crucial in persistent or recurrent disease after surgery since morbidity and mortality are more associated with hypercalcemia than with tumor burden.

ABSTRACT

Resumen: Introducción: el hiperparatiroidismo primario por un adenoma gigante de paratiroides es infrecuente. Los adenomas de mayor tamaño reportados ocurrieron sobre paratiroides ectópicas (mediastinales). Comparte con el carcinoma su gran tamaño y elevadas cifras de calcemia y de hormona paratiroidea, hecho que dificulta el diagnóstico. Su tratamiento quirúrgico es la paratiroidectomía mediante una cervicotomía transversa centrada en la región infrahioidea. Objetivo: presentar un caso clínico de hiperparatiroidismo primario por un adenoma gigante de paratiroides tratado quirúrgicamente mediante un abordaje selectivo. Caso clínico: paciente de 53 años, sexo femenino, con antecedentes de litiasis ureteral, dolores óseos y tumoración infrahiodea de 4 cm de diámetro que imagenológicamente presentó las características de un adenoma paratiroideo inferior izquierdo. La valoración funcional confirmó hiperparatiroidismo. Con diagnóstico de hiperparatiroidismo primario por adenoma gigante se trató quirúrgicamente a través de una incisión pequeña y centrada en la tumoración, realizándose la paratiroidectomía inferior izquierda con la cual remitió la sintomatología y normalizó la funcionalidad paratiroidea. Discusión: el hiperparatiroidismo primario por adenoma gigante de paratiroides tiene indicación quirúrgica y es curativo. El caso presentado demuestra la factibilidad y seguridad de un abordaje selectivo a lo que suma una menor afectación cosmética, dejando indemne la logia tiroidea contralateral ante futuras cirugías sobre ésta.


Summary: Introduction: primary hyperparathyroidism caused by giant parathyroid adenoma is a rather unusual condition. Reported large adenomas occurred in ectopic parathyroid glands (mediastinal). Just like carcinomas, they are large, present high calcemia and parathyroid hormone values, what complicates diagnosis. Surgical treatment consists in parathyroidectomy by means of transversal cervicotomy around the infrahyoid region. Objective: the study presents the clinical case of primary hyperparathyroidism caused by giant parathyroid adenoma that was treated by selective surgery approach. Clinical case: 53 year-old female patient with a history of uretheral lithiasis, bone pain and 4-cm-diameter infrahyoid tumor. Imagenology studies revealed the characteristics of lower left parathyroid adenoma. Functional assessment confirmed hyperparathyroidism. Upon the diagnosis of primary hyperparathyroidism caused by giant parathyroid adenoma it was surgically addressed by means of a small cut around the tumour and performing a lower left parathyroidectomy, what resulted in the remission of symptoms and normalized parathyroid functionality. Discussion: primary hyperparathyroidism caused by giant parathyroid adenoma has an indication for surgery and is therapeutic. The case presented shows the feasibility and safety of a selective approach, as well as its smaller cosmetic harm, managing to keep the contralateral thyroid loggia intact, in view of future surgeries involving it.

Compartilha com o carcinoma seu grande tamanho e altos níveis de cálcio e hormônio da paratireoide, o que torna o diagnóstico difícil. Seu tratamento cirúrgico é a paratireoidectomia por meio de cervicotomia transversa com foco na região infra-hióidea. Objetivo: apresentar um caso clínico de hiperparatireoidismo primário por adenoma gigante da paratireoide tratado cirurgicamente por abordagem seletiva. Caso clínico: paciente do sexo feminino, 53 anos, com história de litíase ureteral, dor óssea e tumor infra-hióideo de 4 cm de diâmetro que apresentava características de imagem de adenoma de paratireoide inferior esquerdo. A avaliação funcional confirmou hiperparatireoidismo. Com diagnóstico de hiperparatireoidismo primário por adenoma gigante, foi tratada cirurgicamente por meio de pequena incisão focada no tumor, realizando paratireoidectomia inferior esquerda com remissão dos sintomas e normalização da funcionalidade da paratireoide. Discussão: o hiperparatireoidismo primário devido ao adenoma gigante da paratireoide tem indicação cirúrgica e é curativo. O caso apresentado demonstra a viabilidade e segurança de uma abordagem seletiva que apresenta um menor envolvimento estético, deixando o espaço contralateral da tireoide sem danos para futuras cirurgias.

ABSTRACT

SUMMARY OBJECTIVE: The parathormone level after parathyroidectomy in dialysis patients are of interest. Low levels may require cryopreserved tissue implantation; however, the resection is necessary in case of recurrence. We analyzed post parathyroidectomy parathormone levels in renal hyperparathyroidism. METHODS: Prospective observation of postoperative parathormone levels over defined periods in a cohort of dialysis patients that underwent total parathyroidectomy and immediate forearm autograft from 2008 to 2010, at a single tertiary care hospital. RESULTS: Of 33 patients, parathormone levels until 36 months could be divided into four patterns. Patients with stable function (Pattern 1) show relatively constant levels after two months (67% of the cases). Early function and later failure (Pattern 2) were an initial function with marked parathormone reduction before one year (18%). Graft recurrence (Pattern 3) showed a progressive increase of parathormone in four cases (12%). Complete graft failure (Pattern 4) was a nonfunctioning implant at any period, which was observed in one patient (3%). Parathormone levels of Pattern 3 became statistically different of Pattern 1 at 36 months. CONCLUSIONS: Patients that underwent the total parathyroidectomy and autograft present four different graft function patterns with a possible varied therapeutic management.

ABSTRACT

Durante las últimas décadas, la incidencia del hiperparatiroidismo primario ha venido en aumento, muy probablemente relacionado con la mayor accesibilidad a los estudios diagnósticos; sin embargo, la forma más común de presentación clínica del hiperparatiroidismo primario es asintomática, en más del 80 % de los pacientes. En la actualidad, es menos frecuente el diagnóstico por las complicaciones renales (urolitiasis) u óseas (osteítis fibrosa quística) asociadas. Un tumor benigno de la glándula paratiroides (adenoma único), es la principal causa de esta enfermedad. Por tanto, su tratamiento usualmente es quirúrgico. A pesar de ello, no es frecuente el manejo de esta patología por el cirujano general. En este artículo se revisan conceptos claves para el diagnóstico y manejo de esta enfermedad para el médico residente y especialista en Cirugía general


During the last decades, the incidence of primary hyperparathyroidism has been increasing, most probably related to the greater accessibility to diagnostic studies; however, the most common form of clinical presentation of primary hyperparathyroidism is asymptomatic in more than 80% of patients. Diagnosis is less frequent due to associated renal (urolithiasis) or bone (osteitis fibrosa cystica) complications. A benign tumor of the parathyroid gland (single adenoma) is the main cause of this disease. Therefore, its treatment is usually surgical. Despite this, the management of this pathology by the general surgeon is not frequent. This article reviews key concepts for the diagnosis and management of this disease for the resident physician and specialist in General Surgery

ABSTRACT

@#Giant parathyroid adenoma (GPA) is defined as adenoma larger than 3.5 g. Twenty-one cases of parathyroid mass >3.5 g in patients with primary hyperparathyroidism who underwent parathyroidectomy in Hospital Putrajaya, Malaysia were identified. Most cases presented with nephrolithiasis. Two cases are reported as parathyroid cancer. GPA has significantly higher serum calcium and iPTH levels and can be asymptomatic. Parathyroid carcinoma patients are frequently symptomatic, with large tumors. Differentiating GPA from parathyroid cancer is important as it determines the subsequent surgical intervention.

ABSTRACT

Objective: To explore the influencing factors for serum potassium >4.4 mmol/L in the morning of parathyroidectomy in hemodialysis patients with secondary hyperparathyroidism (SHPT). Methods: The clinical data of 72 patients with SHPT who received regular hemodialysis and underwent parathyroidectomy in Guangdong Provincial People's Hospital from January 2012 to December 2018 were analyzed retrospectively. There were 37 males and 35 females, aged from 25 to 69 years, and the dialysis timespan was from 0.5 to 11 years. The levels of parathyroid hormone, serum potassium and serum calcium before hemodialysis were examined one day before operation, and hemodialysis time and dewatering volume after hemodialysis without heparin were recorded, and also the level of serum potassium in the morning of parathyroidectomy was detected. The occurrences of hyperkalemia during and after operation were studied. The factors related to hyperkalemia in the morning of parathyroidectomy were evaluated by Pearson or Spearman correlation analysis, and the cut-off values of risk factors were calculated by receiver operating characteristic (ROC) curve. Results: Serum potassium >4.4 mmol/L in the morning of parathyroidectomy existed in 23 of 72 patients. Correlation analysis showed that serum potassium one day before operation ((4.93±0.56)mmol/L, r=0.656, P<0.001) and dehydration volume ((2.37±0.75)L, r=0.261, P=0.027) were positively correlated with serum potassium in the morning of parathyroidectomy((4.16±0.54)mmol/L). Serum potassium before hemodialysis one day before operation was a main predictor for serum potassium in the morning of parathyroidectomy (AUC=0.791, P<0.001). The cut-off value of serum potassium before hemodialysis one day before operation was 5.0 mmol/L. Conclusion: Serum potassium before hemodialysis one day before operation in patients with SHPT can predict serum potassium in the morning of parathyroidectomy, offering imformation for the safety of operation.

ABSTRACT

Objective: To explore the values of intraoperative fine-needle aspiration (IFNA) and parathyroid hormone (PTH) detection in the eluate of aspirated tissue during parathyroidectomy. Methods: Fifty-four patients with secondary hyperparathyroidism (SHPT) including 24 males and 30 females, aged 20-83 years, admitted to Zhongnan Hospital of Wuhan University from January 2019 to October 2019, were included. All patients received subtotal parathyroidectomy with autologous transplantation, during surgery, IFNA and PTH detection in the eluate of aspirated tissue were performed, and also routine postoperative pathological examination was performed. The results of PTH detection in the eluate of aspirated tissue and postoperative pathological examinations were compared and analyzed by SPSS and R software for evaluating of the sensitivity, specificity, positive predictive value, negative predictive value, misdiagnosis rate, missed diagnosis and accuracy. Results: Surgery was completed successfully in all patients. After surgery, the symptoms were improved in the patients except two who were asymptomatic. None had any serious postoperative complications such as hypocalcaemia or hoarseness. A total of 231 aspirated tissue samples were tested, of which 216 were identified as parathyroid and 15 non-parathyroid based on intraoperative PTH detection in tissue eluate; while 217 were confirmed as parathyroid tissues and 14 non-parathyroid tissues with postoperative pathological examinations. The specificity and sensitivity of intraoperative IFNA and PTH detection in tissue eluate for identifying parathyroid tissues were 99.5% and 100.0%, respectively. Conclusion: The IFNA and PTH detection in tissue eluate is a rapid, simple, and accurate procedure, which helps the surgeon to identify parathyroid tissue and to ensure the endocrine activity of preserved or autografted parathyroid tissue during parathyroidectomy.

ABSTRACT

OBJECTIVE@#To summarize and analyze the clinical characteristics of primary hyperpara-thyroidism (PHPT) with normocalcemic parathormone elevation (NPE) after surgical treatment, so as to improve the therapeutic ability and standardized post-operative follow-up of PHPT patients.@*METHODS@#Nine patients who were diagnosed with PHPT in the Department of Endocrinology of China-Japan Friendship Hospital from August 2017 to November 2019 were selected as the subjects. They all developed NPE within 6 months after surgical treatment. The clinical features and outcomes were collected and analyzed retrospectively, in addition, the related literature was reviewed.@*RESULTS@#Clinical features: among the 9 patients, 6 were middle-aged and elderly females and 3 were male. The main clinical manifestations were bone pain, kidney stones, nausea and fatigue except for one case of asymptomatic PHPT. Pre-operative examination showed high serum calcium [(3.33±0.48) mmol/L], low serum phosphorus [0.76 (0.74, 0.78) mmol/L], high 24-hour urinary calcium [8.1(7.8, 12.0) mmol/24 h], obviously elevated intact PTH [(546.1±257.7) ng/L], vitamin D deficiency [25-hydroxyvitamin D3 (21.0±5.7) nmol/L]. Serum levels of bone alkaline phosphatase [7 patients 41.3(38.6, 68.4) μg/L, 2 patients >90 μg/L] and N-terminal midcourse osteocalcin (>71.4 μg/L) were significantly elevated. The estimated glomerular filtration rate decreased in 2 patients. Imaging examination: 7 patients had osteoporosis. Renal calculi were found in 3 patients by renal ultrasound. Imaging examination of parathyroid glands found definite lesions in all the patients, including 2 cases of multiple lesions and 7 cases of single lesions.@*TREATMENT AND OUTCOME@#two patients underwent parathyroidectomy, while other patients were treated with microwave thermal ablation. PTH increased 1 month after therapy [(255.0±101.4) ng/L], and no recurrent lesions were found by parathyroid ultrasound. After combined treatment with cal-cium and vitamin D for six months, PTH decreased significantly and the level of serum calcium remained normal at anytime during the follow-up period.@*CONCLUSION@#The occurrence of postoperative NPE may be related to the higher pre-operative PTH, vitamin D deficiency and lower creatinine clearance. However, NPE may not predict recurrent hyperthyroidism or incomplete parathyroidectomy. Adequate calcium and vitamin D supplementation after surgery seems to be beneficial for patients with NPE. Post-operative follow-up of PHPT patients should be standardized to prevent and treat post-operative NPE.

Leontiasis ossea is an uncommon complication of advanced chronic kidney disease that alters the facial bone and the airway, making its perioperative management more complex. We present a clinical case of a female with Leontiasis ossea presenting a difficult airway which requires parathyroidectomy. Assessment, planning and management of the airway by awake intubation is described.

ABSTRACT

ABSTRACT Background: Persistent hyperparathyroidism post-transplant is associated with increases in the incidence of cardiovascular events, fractures, and deaths. The aim of this study was to compare both therapeutic options available: parathyroidectomy (PTX) and the calcimimetic agent cinacalcet. Methods: A single center retrospective study including adult renal transplant recipients who developed hypercalcemia due to persistent hyperparathyroidism. Inclusion criteria: PTH > 65 pg/mL with serum calcium > 11.5 mg/dL at any time after transplant or serum calcium persistently higher than 10.2 mg/dL one year after transplant. Patients treated with cinacalcet (n=46) were compared to patients treated with parathyroidectomy (n=30). Follow-up period was one year. Clinical and laboratory data were analyzed to compare efficacy and safety of both therapeutic modalities. Results: PTX controlled calcemia faster (month 1 x month 6) and reached significantly lower levels at month 12 (9.1±1.2 vs 9.7±0.8 mg/dL, p < 0.05); PTX patients showed significantly higher levels of serum phosphate (3.8±1.0 vs 2.9±0.5 mg/dL, p < 0.05) and returned PTH to normal levels (45±51 pg/mL). Cinacalcet, despite controlling calcium and phosphate in the long term, decreased but did not correct PTH (197±97 pg/mL). The proportion of patients that remained with PTH above normal range was 95% in the cinacalcet group and 22% in the PTX group. Patients treated with cinacalcet had better renal function (creatinine 1.2±0.3 vs 1.7±0.7 mg/dL, p < 0.05). Conclusions: Surgical treatment was superior to cinacalcet to correct the metabolic disorders of hyperparathyroidism despite being associated with worse renal function in the long term. Cinacalcet proved to be a safe and well tolerated drug.


RESUMO Introdução: O hiperparatireoidismo persistente pós-transplante está associado a aumento na incidência de eventos cardiovasculares, fraturas e óbitos. O objetivo deste estudo foi comparar as opções terapêuticas disponíveis: paratireoidectomia (PTX) e o agente calcimimético cinacalcete. Métodos: Estudo retrospectivo de um único centro incluiu pacientes transplantados renais adultos que desenvolveram hipercalcemia devido a hiperparatireoidismo persistente. Critérios de inclusão: PTH > 65 pg/mL com cálcio sérico > 11,5 mg/dL a qualquer momento após o transplante, ou cálcio sérico persistentemente superior a 10,2 mg/dL um ano após o transplante. Os pacientes tratados com cinacalcete (n = 46) foram comparados aos pacientes tratados com paratireoidectomia (n = 30). O período de acompanhamento foi de um ano. Dados clínicos e laboratoriais foram analisados para comparar a eficácia e a segurança de ambas as modalidades terapêuticas. Resultados: a PTX controlou a calcemia mais rapidamente (mês 1 x mês 6) e atingiu níveis significativamente mais baixos no mês 12 (9,1 ± 1,2 v.s. 9,7 ± 0,8 mg/dL, p < 0,05); pacientes submetidos à PTX apresentaram níveis significativamente mais altos de fósforo sérico (3,8 ± 1,0 v.s. 2,9 ± 0,5 mg/dL, p < 0,05) e retornaram aos níveis normais de PTH (45 ± 51 pg/mL). O cinacalcete, apesar de controlar o cálcio e o fósforo no longo prazo, diminuiu, mas não corrigiu o PTH (197 ± 97 pg/mL). A proporção de pacientes que permaneceram com PTH acima da faixa normal foi de 95% no grupo cinacalcete e 22% no grupo PTX. Os pacientes tratados com cinacalcete apresentaram melhor função renal (creatinina 1,2 ± 0,3 v.s. 1,7 ± 0,7 mg/dL, p < 0,05). Conclusões: O tratamento cirúrgico foi superior ao cinacalcete para corrigir os distúrbios metabólicos do hiperparatireoidismo, apesar de estar associado a pior função renal no longo prazo. Cinacalcete provou ser um medicamento seguro e bem tolerado.

ABSTRACT

RESUMEN Introducción: El tratamiento quirúrgico ha evolucionado desde la exploración abierta bilateral del cuello hasta la cirugía de invasión mínima. En este momento, la paratiroidectomía mínimamente invasiva en pacientes con hiperparatiroidismo primario es la técnica de elección. Objetivo: Describir los resultados del tratamiento quirúrgico del hiperparatiroidismo primario con el uso de la sonda gamma transoperatoria. Métodos: Se realizó un estudio descriptivo y longitudinal, de tipo serie de casos. La muestra estuvo constituida por 29 pacientes con tratamiento quirúrgico radioguiada para el hiperparatiroidismo primario en el Hospital Clínico Quirúrgico Hermanos Ameijeiras entre marzo de 2007 a diciembre de 2014. Resultados: De los 29 pacientes, 21 no presentaban enfermedad tiroidea asociada, tenían una mediana de edad de 52 años, con predominio femenino (80,9 por ciento), la enfermedad renal resultó ser el síntoma más frecuente (52,4 por ciento), el adenoma paratiroideo fue el diagnóstico anatomopatológico con mayor por ciento (85,7 por ciento). Presentaron complicaciones posoperatorias el 38,1 por ciento y la hipocalcemia transitoria estuvo en un 28,6 por ciento. La media de la estadía posoperatoria fue de 3,37 días y la curación de 90,5 por ciento. En los ocho pacientes con enfermedad tiroidea asociada tenían una mediana de edad de 58 años y predominio femenino (62,5 por ciento). Prevaleció el dolor articular y la fatiga (50 por ciento) como síntomas previos y como diagnóstico anatomopatológico el adenoma paratiroideo (62,5 por ciento). Las complicaciones presentes en un 37,5 por ciento y la más frecuente la hipocalcemia transitoria (25,0 por ciento). La curación estuvo en 62,5 por ciento y la media de la estadía posoperatoria en 2,47 días. Conclusiones: Los resultados alcanzados evidencian la utilidad de la cirugía radioguiada en el tratamiento del hiperparatiroidismo primario(AU)


ABSTRACT Introduction: Surgical treatment has evolved from bilateral open neck exploration to minimally invasive surgery. Currently, minimally invasive parathyroidectomy in patients with primary hyperparathyroidism is the technique of choice. Objective: To describe the outcomes of surgical treatment of primary hyperparathyroidism with the use of the intraoperative gamma probe. Methods: A descriptive and longitudinal study of case series was carried out. The sample consisted of 29 patients who received radioguided surgical treatment for primary hyperparathyroidism at Hermanos Ameijeiras Clinical-Surgical Hospital between March 2007 and December 2014. Results: Of the 29 patients, 21 did not present associated thyroid disease. Their median age was 52 years. They were predominantly female (80.9%). Kidney disease was the most frequent symptom (52.4 percent). Parathyroid adenoma was the anatomopathological diagnosis with the highest percentage value (85.7 percent). 38.1 percent presented postoperative complications and transient hypocalcemia accounted for 28.6 percent. The mean for postoperative stay was 3.37 days and for healing was 90.5 percent. In the eight patients with associated thyroid disease, the mean age was 58 years, and there was predominance of the female sex (62.5 percent). Joint pain and fatigue, accounting for 50 percent, prevailed as previous symptoms; while parathyroid adenoma, accounting for 62.5 percent, prevailed as anatomopathological diagnosis. Complications were present in 37.5 percent and the most frequent was transient hypocalcemia (25.0 percent). Healing accounted for 62.5 percent and the mean postoperative stay was 2.47 days. Conclusions: The results obtained show the usefulness of radioguided surgery in the treatment of primary hyperparathyroidism(AU)
