Autofluorescence-guided hemithyroidectomy in a low-volume thyroid institution with no experience in parathyroid surgery: randomized clinical trial.

BACKGROUND: Recent studies suggest that low-volume surgeons with no experience in parathyroid surgery are at increased risk of causing parathyroid gland damage during thyroid surgery. The aim of this RCT was to evaluate the impact of using autofluorescence in hemithyroidectomy on parathyroid gland identification and preservation in a low-volume institution with no experience in parathyroid surgery. METHODS: Patients referred for hemithyroidectomy were randomized 1 : 1 to either autofluorescence-guided hemithyroidectomy (the near-infrared autofluorescence group) or conventional hemithyroidectomy (the control group). The primary outcome was parathyroid gland identification rate. Secondary outcomes were the rate of parathyroid gland autotransplantation and the rate of inadvertent parathyroid gland excision. RESULTS: A total of 170 patients were randomized to either autofluorescence-guided hemithyroidectomy (84 patients) or conventional hemithyroidectomy (86 patients). In the near-infrared autofluorescence group, 81.0% of parathyroid glands were identified, compared with 57.0% in the control group (P < 0.001). Autofluorescence enabled parathyroid gland visualization before the naked eye in 46.3% of cases. Surgeons had lower confidence in the parathyroid gland identification process in the control group than in the near-infrared autofluorescence group (59.1% versus 87.5% respectively; P < 0.001). In the near-infrared autofluorescence group, the parathyroid gland autotransplantation rate was initially high, but declined over time. There was no difference in the rate of inadvertent parathyroid gland excision. CONCLUSION: Autofluorescence guidance significantly improved the parathyroid gland identification rate in hemithyroidectomy in a low-volume institution with no experience in parathyroid surgery and provided an increase in surgical confidence. The pattern of parathyroid gland autotransplantation in autofluorescence-guided surgery indicates the presence of a learning curve. REGISTRATION NUMBER: NCT05044351 (http://www.clinicaltrials.gov).

Damage to the parathyroid glands is common during thyroid surgery. The main reason for that is that they can be difficult to see during surgery. The aim of this study was to see if the use of a new near-infrared camera during thyroid surgery could make it easier to see the parathyroid glands. Patients, where removal of part of their thyroid gland was planned, were randomly assigned to one of two groups. In the first group, the near-infrared camera was used, whereas it was not used in the other group. When the near-infrared camera was used, more parathyroid glands were found and the surgeons felt more secure in their handling of parathyroid glands.

Clinico-pathologic profile and outcomes of pediatric endocrine patients managed by endocrine surgeons: Experience over three decades in a tertiary center in India.

BACKGROUND: Pediatric endocrine disorders requiring surgical intervention are rare and so are experienced surgeons dealing with these. The aim of the current study was to investigate disease profile and perioperative outcome of pediatric patients with surgical endocrine disorders in an endocrine surgery unit. METHODS: This retrospective study (Sep 1989-Aug 2019) consisted of pediatric endocrine surgery patients (<18 years) who were managed by a team of pediatric endocrinologists and endocrine surgeons at our center. Patients were divided into three cohorts consisting of a decade each. Clinico-pathologic variables, perioperative events operative and follow-up details were recorded. RESULTS: A total of 332 children were included and their mean age was 14.6 ± 3.9 years (M:F = 1:1.6). Thyroid disorders were most prevalent (59.8%), followed by adrenal (28.2%), parathyroid (10.4%), and pancreas (1.5%). Incidence of benign, malignant, and congenital/developmental disorders were 65.4, 28.1 and 8.3, respectively. Familial association was observed in 8.9% children, which is highest among pheochromocytoma patients. Overall, 201 thyroidectomies + associated procedures, 35 parathyroidectomies, 96 adrenal and paraganglioma resections, and 5 pancreatic procedures were performed. Median hospital stay was 5.6 ± 4.1 days. The number of cases increased significantly over 3 decades. Clinical profile and outcome did not vary except for significant decrease in incidence of malignant pathology (p = 0.04) and increase in VHL cases (p = 0.04) in the last decade though overall increase in familial cases was nonsignificant (p = 0.11). No perioperative mortality was observed except for 3% after adrenalectomy. CONCLUSION: A team of dedicated endocrine surgeons and pediatric endocrinologists is effective in management of pediatric endocrine surgery.

[Gender medicine: endocrine and neuroendocrine diseases : Implications for surgery and perioperative management]. / Gendermedizin: endokrine und neuroendokrine Erkrankungen : Besonderheiten für Chirurgie und perioperatives Management.

Gender medicine is also becoming increasingly more important in the field of surgery of endocrine and neuroendocrine diseases. Gender differences in the incidence, symptoms and disease progression are common to all (neuro)endocrine diseases. Understanding these special features, which include socioeconomic aspects as well as different anatomical and biological factors, is essential for the selection of optimal diagnostics and treatment but in some cases further scientific research is required. To date, there is a paucity of gender-specific recommendations in established guideline recommendations. There is an enormous potential in all areas of endocrine surgery to take advantage of differences between men and women in the diagnostics, surgical treatment and perioperative management. Individualized approaches could lead to improved surgical outcomes, reduced perioperative complications and improved follow-up.

A multi-institutional study from the US ROPE consortium examining factors associated with endocrine surgery exposure for general surgery residents.

BACKGROUND: Prior analyses of general surgery resident case logs have indicated a decline in the number of endocrine procedures performed during residency. This study aimed to identify factors contributing to the endocrine operative experience of general surgery residents and compare those who matched in endocrine surgery fellowship with those who did not. METHODS: We analyzed the case log data of graduates from 18 general surgery residency programs in the US Resident Operative Experience Consortium over an 11-year period. RESULTS: Of the 1,240 residents we included, 17 (1%) matched into endocrine surgery fellowships. Those who matched treated more total endocrine cases, including more thyroid, parathyroid, and adrenal cases, than those who did not (81 vs 37, respectively, P < .01). Program-level factors associated with increased endocrine volume included endocrine-specific rotations (+10, confidence interval 8-12, P < .01), endocrine-trained faculty (+8, confidence interval 7-10, P < .01), and program co-location with otolaryngology residency (+5, confidence interval 2 -8, P < .01) or endocrine surgery fellowship (+4, confidence interval 2-6, P < .01). Factors associated with decreased endocrine volume included bottom 50th percentile in National Institute of Health funding (-10, confidence interval -12 to -8, P < .01) and endocrine-focused otolaryngologists (-3, confidence interval -4 to -1, P < .01). CONCLUSION: Several characteristics are associated with a robust endocrine experience and pursuit of an endocrine surgery fellowship. Modifiable factors include optimizing the recruitment of dedicated endocrine surgeons and the inclusion of endocrine surgery rotations in general surgery residency.

Health Care Disparities in Endocrine Surgical Disorders.

While there has been great progress in the past few decades in the management of endocrine surgery disorders, with adoption of new technologies and approaches, standardization of practice patterns, and guideline recommendations, unequal implementation of these improvement has led to differences in access and outcomes. Health disparities are well documented in this population; however, literature lacks discussion of strategies to decrease disparities. In this article, the authors will describe the current status of health care-related disparities in endocrine surgical care, and discuss opportunities for future investigation and issue an urgent call to action items.

Bridging the Gap: A Qualitative Assessment of General Surgery Resident Confidence and Knowledge Deficits in Managing Surgical Endocrinopathy.

BACKGROUND: Most thyroid and parathyroid surgeries are performed by nonfellowship trained, low-volume surgeons with associated higher complication rates. Furthermore, the average number of endocrine procedures performed by general surgery residents is decreasing. While previous studies have documented a lack of general surgery resident confidence in performing these procedures, the specific knowledge gaps in endocrine surgery remain unexplored. METHODS: We conducted semi-structured interviews with surgical residents (clinical PGY3-PGY5) at a high-volume academic center with an endocrine surgery fellowship to discuss their experience, knowledge, and deficits managing patients with surgical thyroid and parathyroid disease. Interviews were audio-recorded, de-identified, and transcribed verbatim. Content analysis was used to identify areas of confidence and knowledge deficits in all phases of care. RESULTS: Overall, 14 trainees participated in the study (50% women, mean PGY: 3.8). Preoperatively, residents were confident with thyroid nodule and primary hyperparathyroidism work-up, but less comfortable with rare conditions. Residents were uncomfortable using ultrasound to identify suspicious lymph nodes or abnormal parathyroid glands. Residents perceived knowledge deficits in the multidisciplinary care and work-up of patients with advanced thyroid cancer. Intraoperatively, most residents were confident performing thyroidectomy and focused parathyroidectomy, but less comfortable performing 4-gland explorations or neck dissections. Several had concern with independently identifying and protecting the recurrent laryngeal nerve or locating parathyroid glands in the setting of negative localization. Residents noted a lack of autonomy in both thyroidectomy and parathyroidectomy. Postoperatively, residents felt confident in the acute management of patients, but identified deficits in long-term management of patients with thyroid cancer or chronic complications. CONCLUSIONS: Despite confidence in managing "bread and butter" cervical endocrine surgery in all phases of care, residents perceive a lack of meaningful autonomy intraoperatively. Further educational endeavors may be required to ensure graduating residents are "practice ready" for straightforward cases they may encounter in practice as a general surgeon. A lack of exposure to complex endocrinopathy even at a high-volume center suggests that comprehensive endocrine surgery fellowship remains critical.

[Endocrine oncology : An update on surgical treatments]. / Endokrine Onkologie : Neues zu chirurgischen Therapien.

BACKGROUND: In the management of solid tumours, routine concepts are increasingly being transformed into individualized patient treatment. Endocrine surgery is traditionally characterized by resection strategies that are adapted to phenotype and genotype of the underlying disease. As complication rates in surgery correlate with the extent of resection, continuous efforts are made to identify selection criteria in order to limit the extent of surgery without compromising the oncological outcome. The aim is to design risk-stratified precision endocrine surgery. MATERIALS AND METHODS: A search was carried out in PubMed for new and modern strategies and approaches for oncological endocrine surgery. RESULTS: Several developments in surgical technique and technology, molecular pathology, medical therapy, and study data identify the potential to adapt the surgical strategy in all areas of endocrine surgery. CONCLUSION: According to prevalent data, limited extent of resection in thyroid cancer surgery shows a reduction in complication rates while preserving oncological outcome when adequate selection criteria are implemented. New insights and innovative technologies also influence additional areas in oncological endocrine surgery for parathyroid, adrenal, and neuroendocrine neoplasia. However, the broad practice of these new concepts needs to be evaluated with regard to long-term oncological outcome.

Tratamiento del hipoparatiroidismo postquirúrgico permanente, servicio endocrinología, Centro Médico Nacional 20 de noviembre, México 2020 / Permanent post-surgical hypoparathyroidism treatment response, outpatient consultation Endocrinology Service, ISSSTE, 2020

El hipoparatiroidismo postquirúrgico se caracteriza por hipocalcemia, hiperfosfatemia, e hipercalciuria, secundarios a concentraciones bajas de la hormona paratiroidea. La prevalencia en Estados Unidos es 23-37 casos/100.000 años-persona. Tras la cirugía de cuello ocurre como complicación en 78% de los casos; 75% resuelve espontáneamente en los primeros 6 meses y en el 25% restante es permanente. El tratamiento requiere administrar calcio oral y análogos de vitamina D (calcitriol y alfacalcidol) de forma crónica; en casos complicados se puede emplear calcio intravenoso en el postquirúrgico inmediato y mediato; algunos pacientes no responden a la terapia estándar. Objetivo: describir las características clínicas y la respuesta al tratamiento médico en pacientes con hipoparatiroidismo postquirúrgico permanente. Material y métodos: estudio descriptivo, transversal, con componente analítico mediante revisión de expedientes clínicos de pacientes que asistieron a la consulta externa del Servicio de Endocrinología del Centro Médico Nacional 20 de Noviembre; universo 88 expedientes, muestra por conveniencia 55 expedientes. Resultados: 35(63.6%) pacientes alcanzaron control óptimo de tratamiento a dosis de calcio elemental de 5.7-9.79g/24h (p= 0.0001 chi cuadrado), mostrando calcio sérico promedio 8.36 0.55 mg/dl y calcitriol con mediana de 0.5µg/24 h. 15(27.2%) pacientes presentaron efectos secundarios al uso de calcio oral, 3 de ellos requirieron manejo con Hormona Paratiroidea Recombinante Humana para alcanzar control óptimo. Conclusión: el calcio elemental por vía oral continúa siendo la piedra angular en el tratamiento del hipoparatiroidismo post quirúrgico permanente, con pocos efectos adversos. Se recomiendan más estudios aleatorizados para identificar las características de los pacientes candidatos al manejo con Hormona Paratiroidea Recombinante Humana...(AU)

Prevención de morbilidades post-tiroidectomía total y subtotal: una revisión bibliográfica / Prevention of total and subtotal post-thyroidectomy morbidities: a bibliographic review

Las enfermedades tiroideas han presentado un auge en los últimos tiempos, aumentando consigo mismo el reporte de las intervenciones quirúrgicas. La tiroidectomía es una de las cirugías más practicadas en endocrinología y tras su realización se han descrito complicaciones, siendo éstas vinculadas a ciertos factores de riesgos que potencian su aparición. Se realizó búsqueda bibliográfica en el período comprendido entre febrero de 2018 a diciembre de 2019, en bases de datos internacionales (PubMed, Cochrane, SCIELO, LILACS y Redalyc) y búsqueda manual en Google Scholar, utilizando los términos complicaciones de tiroidectomías, complicaciones post-quirúrgicas, cirugía de tiroides y tiroidectomías. Se identificaron tres agrupaciones generales de factores de riesgo postquirúrgico: Factores intrínsecos de la enfermedad, comorbilidades del paciente y asociados al procedimiento quirúrgico. Es indispensable identificar y corregir comorbilidades para la prevención de complicaciones postquirúrgicas, puesto que las complicaciones continúan siendo una causa de considerable preocupación.

There are currently several developing areas for the application of fluorescence in endocrine surgery, including the use of fluorescence with indocyanine green in adrenal gland surgery, the identification and prediction of parathyroid perfusion with indocyanine green, and autofluorescence of the parathyroid glands. The objective of this article is to review the current applications of fluorescence in endocrine surgery

Hiperparatiroidismo primario asociado a neoplasia endocrina múltiple tipo 1 (MEN 1). Experiencia en 71 casos / Primary hyperparathyroidism associated with MEN 1: Experience in 71 cases

INTRODUCCIÓN: El hiperparatiroidismo (HPT) asociado al MEN 1 se caracteriza por ser una afectación multiglandular, no afectándose todas las glándulas en el mismo momento. Suele ser asintomático, aunque la afectación ósea es elevada en los pacientes jóvenes. Las tasa de recidiva y persistencias es de 25-35%. Los objetivos fueron: a) estudiar HPT-MEN 1; y b) analizar las variables relacionadas con la presencia o no de clínica y con la persitencia. MÉTODO: De 97 sujetos con MEN 1 diagnosticados en el HUVA, Murcia, pertenecientes a 16 familias, se han estudiado restrospectivamente 71 pacientes con afectación paratiroidea. Las variables estudiadas son: mutación, edad de diagnóstico, clínica, los valores de calcio, fóforo y PTHi, MIBI, técnica quirúrgica, valores de la PTHi y tasa de recidiva. RESULTADOS: La edad media fue de 38 años, y 50 estaban asintomáticos en el momento del diagnóstico. La técnica quirúgica realizada fue: paratiroidectomía subtotal (n = 55), paratiroidectomía de 3 glándulas (n = 7) y resección de menos de 3 glándulas (n = 9). Se asoció timectomía transcervical en 53. El seguimiento medio ha sido de 102,9 meses. Se han encontrado 21 recidivas (10 cirugía incompleta). Encontramos una relación estadísticamente significativa entre: la edad de diagnóstico (p < 0,0005) y los valores elevados de calcio (p < 0,008) y la presencia de clínica en el momento del diagnóstico, la técnica quirúrgica incompleta (p < 0,003), no timectomía (p < 0,0001) y seguimiento (p < 0,001) y la recidiva tras la cirugía. CONCLUSIÓN: La realización de screening genético y clínico nos permite un diagnóstico en fase asintomática y tratamiento precoz, evitando así complicaciones secundarias a la evolución del HPT. La tasa de recidiva del HPT en el MEN 1 es elevada, siendo los factores de recidiva el tiempo de seguimiento y la técnica quirúrgica realizada

INTRODUCTION: Primary hyperparathyroidism (pHPT) in MEN 1 is characterized by multiglandular disease and early involvement of parathyroid glands at different times. Persistence and recurrence range from 25%-35%. The purpose was: a) to describe the experience and the treatment of patients with pHPT in MEN 1; b) to analyze the variables related with clinical presentation and recurrence. METHOD: A total of 97 patients with MEN 1 were diagnosed in a tertiary hospital. A retrospective analysis was made in patients with pHPT (n = 71). Study variables: age at diagnosis, mutation, clinical presentation, laboratory tests, surgical technique, and recurrence of HPT. RESULTS: Mean age was 38 years, and 50 patients were asymptomatic. The surgical technique was: subtotal parathyroidectomy (n = 55), resection of three glands (n = 7), and resection of less glands (n = 9). Transcervical thymectomy was performed in 53 patients. Mean follow-up was 102.9 months. There were 21 recurrences, There were correlations between age at diagnosis and serum calcium levels with the presence of symptoms (P < .0001). There were also correlations between recurrence and surgical technique (P < .03), non-association with thymectomy (P < .0001), and follow-up time (P < .03). CONCLUSION: Performing genetic and clinical screening allows us to make a diagnosis in the asymptomatic period and to provide early treatment for HPT in MEN 1. The recurrence rate is high, and follow-up time and the surgical technique used are risk factors for recurrence
