Indicación, realización y resultado del cateterismo de venas adrenales en pacientes con hiperaldosteronismo primario / Indication, performance and outcomes of adrenal vein sampling in patients with primary hyperaldosteronism

El hiperaldosteronismo primario (HAP) es una causa importante de hipertensión arterial (HTA) secundaria. El estudio del mismo precisa de una alta sospecha clínica, además de un estudio hormonal que confirme la hipersecreción hormonal. Es importante iniciar el tratamiento adecuado una vez se confirma el diagnóstico, y para ello es preciso demostrar si la hipersecreción hormonal es unilateral (pacientes que podrían ser tributarios a tratamiento quirúrgico) o bilateral (pacientes que son tributarios a tratamiento únicamente farmacológico). En el Hospital del Mar desde el año 2016 existe un equipo de trabajo multidisciplinar en el que participan nefrólogos, endocrinólogos, radiólogos y cirujanos para evaluar los casos con sospecha de hiperaldosteronismo y consensuar el mejor abordaje diagnóstico-terapéutico de estos pacientes, incluyendo la necesidad de cateterismo venoso adrenal, que es una técnica que en los últimos años se ha erigido como gold standard para el estudio del HAP. En el presente estudio recogemos la experiencia de nuestro centro en la realización de cateterismo venoso adrenal y en la utilidad de este para el manejo de tales pacientes (AU)

Primary hyperaldosteronism (PAH) is an important cause of secondary hypertension (HTN). The study of the same requires a high clinical suspicion in addition to a hormonal study that confirms hormonal hypersecretion. It is important to start the appropriate treatment once the diagnosis is confirmed, and for this is necessary to demonstrate whether the hormonal hypersecretion is unilateral (patients who could be candidates for surgical treatment) or bilateral (patients who are candidates for pharmacological treatment only). At the Hospital del Mar since 2016 there has been a multidisciplinary work team in which Nephrologists, Endocrinologists, Radiologists and Surgeons participate to evaluate cases with suspected hyperaldosteronism and agree on the best diagnostic-therapeutic approach for these patients, including the need for adrenal vein sampling, which is a technique that in recent years has become the gold standard for the study of PAH. In the present study we collect the experience of our center in performing adrenal vein catheterization and its usefulness for the management of these patients (AU)

THERAPY OF ENDOCRINE DISEASE: Central neck dissection: a step forward in the treatment of papillary thyroid cancer.

Since its introduction in the '70s and '80s, CND for papillary cancer is here to stay. Compartment VI should always be explored during surgery for papillary thyroid carcinoma (PTC) for obvious lymph node metastases. These can be easily spotted by an experienced surgeon or, eventually, by frozen section. No doubt, obvious nodal disease in the Delphian, paratracheal and subithsmic areas should be dissected in a comprehensive manner (therapeutic central neck dissection), avoiding the selective removal of suspicious nodes. Available evidence for routine prophylactic CND is not completely satisfactory. Our group's opinion, however, is that it reduces or even eliminates the need for repeat surgery in the central neck, better defines the extent (and stage) of the disease and provides a further argument against routine radioiodine ablation. Thus, PTC is becoming more and more a surgical disease that can be cured by optimized surgery alone in the majority of cases. Prophylactic CND, however, involves a higher risk for the parathyroid function and should be skilfully performed, preferably only on the same side as the primary tumour and preserving the cervical portion of the thymus.

Utilidad de la escala Obesity surgery mortality risk score en la predicción de complicaciones tras cirugía bariátrica por vía laparoscópica / Obesity surgery mortality risk score for the prediction of complications after laparoscopic bariatric surgery

INTRODUCCIÓN: La morbimortalidad tras la cirugía bariátrica varía según las características de los pacientes y las comorbilidades asociadas. El objetivo de este estudio fue evaluar la posible utilidad de la escalaObesity sugery mortality risk score (OS-MRS) para prever el riesgo de complicaciones postoperatorias tras cirugía bariátrica. MÉTODOS: Estudio retrospectivo de una serie prospectiva de pacientes intervenidos de cirugía bariátrica a los que se aplicó antes de la operación la escala OS-MRS. Se clasificaron las complicaciones postoperatorias siguiendo la propuesta de Dindo-Clavien. Se analizó la relación entre las categorías de la escala OS-MRS: A) bajo riesgo; B) riesgo intermedio y C) riesgo elevado, y la presencia de complicaciones. RESULTADOS: Entre mayo del 2008 y junio del 2012 se incluyó a 198 pacientes (85 [42,9%] a los que se realizó un bypass gástrico y 113 [57,1%] con una gastrectomía vertical). Utilizando la escala OS-MRS, 124 pacientes se clasificaron como clase A (62,6%), 70 como clase B (35,4%) y 4 como clase C (2%). La tasa de morbilidad global fue del 12,6% (25 pacientes). Se demostró una asociación significativa entre la escala OS-MRS y la tasa de complicaciones (7,3, 20 y 50%, respectivamente; p = 0,004). El bypass gástrico se asociaba a mayor número de complicaciones que la gastrectomía vertical (p = 0,007). En el análisis multivariado, la escala OS-MRS y la técnica quirúrgica fueron los únicos factores con valor predictivo. CONCLUSIONES: La escala OS-MRS es una herramienta útil para predecir el riesgo de complicaciones y puede orientar a la hora de escoger el tipo de cirugía bariátrica

INTRODUCTION: Morbimortality after bariatric surgery varies according to patient characteristics and associated comorbidities. The aim of this study was to evaluate the usefulness of the obesity surgery mortality risk score scale (OS-MRS) to predict the risk of postoperative complications after bariatric surgery. METHODS: A retrospective study was performed on a prospective series of patients undergoing bariatric surgery in which the OS-MRS scale was applied preoperatively. Postoperative complications were classified as proposed by Dindo-Clavien. We analysed the relationship between the categories of OS-MRS scale: (A) low risk, (B) intermediate risk, and (C) high risk and the presence of complications. RESULTS: Between May 2008 and June 2012, 198 patients were included (85 [42.9%] after gastric bypass and 113 [57.1%] after sleeve gastrectomy). Using the OS-MRS scale, 124 patients were classified as class A (62.6%), 70 as class B (35.4%) and 4 as class C (2%). The overall morbidity rate was 12.6% (25 patients). A significant association between OS-MRS scale and rate of complications (7.3, 20 and 50%, respectively, P=.004) was demonstrated. The gastric bypass was associated with a higher complication rate than sleeve gastrectomy (P=.007). In multivariate analysis, OS-MRS scale and surgical technique were the only significant predictive factors. CONCLUSIONS: The OS-MRS scale is a useful tool to predict the risk of complications and can be used as a guide when choosing the type of bariatric surgery

Impacto de un programa de rehabilitación multimodal en cirugía electiva colorrectal sobre los costes hospitalarios / Multimodal rehabilitation program in elective colorectal surgery: Impact on hospital costs

Introducción Los programas de rehabilitación multimodal (RHMM) en cirugía han demostrado un beneficio en la recuperación funcional de los pacientes. Nuestro objetivo fue evaluar el impacto de un programa de RHMM en los costes hospitalarios.Material y métodosEstudio prospectivo comparativo de cohortes consecutivas de pacientes intervenidos de cirugía colorrectal electiva. En la primera cohorte analizamos 134 pacientes que recibieron un control postoperatorio convencional (grupo control). En la segunda cohorte se incluye a 231 pacientes tratados con un programa de RHMM (grupo RHMM). Se analiza el cumplimiento del protocolo y la recuperación funcional de los pacientes del grupo RHMM. Se comparan las complicaciones postoperatorias, la estancia hospitalaria y los reingresos en ambos grupos. El análisis de costes se ha basado en la contabilidad analítica del centro.ResultadosLas características demográficas y clínicas de los pacientes fueron similares entre grupos. No encontramos diferencias en la morbimortalidad global. La estancia media postoperatoria fue 3 días menor en el grupo RHMM. No se observaron diferencias significativas en la tasa de reingresos. Los costes totales por paciente fueron significativamente menores en el grupo RHMM (RHMM: 8.107 ± 4.117 euros vs. control: 9.019 ± 4.667 euros; p = 0,02). El principal factor que contribuyó a la reducción de los costes fue el descenso de los gastos de la Unidad de Hospitalización.ConclusionesLa aplicación de un protocolo de RHMM en cirugía electiva colorrectal reduce, no solo la estancia hospitalaria, sino también los costes hospitalarios, sin aumentar la morbilidad postoperatoria ni el porcentaje de reingresos (AU)

Introduction Multimodal rehabilitation (MMRH) programs in surgery have proven to be beneficial in functional recovery of patients. The aim of this study is to evaluate the impact of a MMRH program on hospital costs.MethodA comparative study of 2 consecutive cohorts of patients undergoing elective colorectal surgery has been designed. In the first cohort, we analyzed 134 patients that received conventional perioperative care (control group). The second cohort included 231 patients treated with a multimodal rehabilitation protocol (fast-track group). Compliance with the protocol and functional recovery after fast-track surgery were analyzed. We compared postoperative complications, length of stay and readmission rates in both groups. The cost analysis was performed according to the system «full-costing».ResultsThere were no differences in clinical features, type of surgical excision and surgical approach. No differences in overall morbidity and mortality rates were found. The mean length of hospital stay was 3 days shorter in the fast-track group. There were no differences in the 30-day readmission rates. The total cost per patient was significantly lower in the fast-track group (fast-track: 8.107 ± 4.117 euros vs. control: 9.019 ± 4.667 Euros; P=.02). The main factor contributing to the cost reduction was a decrease in hospitalization unit costs.ConclusionThe application of a multimodal rehabilitation protocol after elective colorectal surgery decreases not only the length of hospital stay but also the hospitalization costs without increasing postoperative morbidity or the percentage of readmissions (AU)

No hubo diferencias en las características de los pacientes entre los 2 grupos. No hubo diferencias en el porcentaje de fracaso del tratamiento entre los 2 grupos (5,5 vs. 4,3%; p = 0,7). El coste global por episodio fue de 882 ± 462 euros en el grupo ambulatorio frente a 2.376 ± 830 euros en el grupo hospitalario (p = 0,0001).Conclusiones El tratamiento ambulatorio de la diverticulitis aguda no solo es seguro y eficaz sino que también reduce más de un 60% los costes sanitarios (AU)

Background Outpatient treatment of uncomplicated acute diverticulitis is safe and effective. The aim of this study was to determine the impact of outpatient treatment on the reduction of healthcare costs. Patients and methods A retrospective cohort study comparing 2 groups was performed. In the outpatient treatment group, patients diagnosed with uncomplicated acute diverticulitis were treated with oral antibiotics at home. In the hospital treatment group, patients met the criteria for outpatient treatment but were admitted to hospital and received intravenous antibiotic therapy. Cost estimates have been made using the hospital cost accounting system based on total costs, the sum of all variable costs (direct costs) plus overhead expenses divided by activity (indirect costs).Results A total of 136 patients were included, 90 in the outpatient treatment group and 46 in the hospital group. There were no differences in the characteristics of the patients in both groups. There were also no differences in the treatment failure rate in both groups (5.5% vs. 4.3%; P=.7). The total cost per episode was significantly lower in the outpatient treatment group (882 ± 462 vs. 2.376 ± 830 euros; P=.0001).Conclusions Outpatient treatment of acute diverticulitis is not only safe and effective but also reduces healthcare costs by more than 60% (AU)

Technical hints and potential pitfalls in modified radical neck dissection for thyroid cancer.

Modified radical neck dissection (MRND) is often performed in conjunction with total thyroidectomy for the management of thyroid cancer. Prevention of postoperative sequelae after MRND is closely dependent on the avoidance of technical mistakes that may lead to significant complications and long-term morbidity. A thorough technical discussion with emphasis on potential pitfalls is made of the most relevant steps of MRND using the extrafascial approach: fascial dissection, approach to the accessory nerve, posterior limits, upper internal jugular vein (IJV), transverse cervical vessels, thoracic duct and compartment V dissection. Some anatomical hints are emphasized to help the novice surgeon to develop a refined surgical technique, the key to an uneventful postoperative course.
