- W3106175032 abstract "La causa más frecuente de hiperparatiroidismo primario (HPP) es el adenoma paratiroideo (único en el 80 a 85% de los casos y doble en un 4%, aproximadamente). El resto de los casos obedece a una hiperplasia de las glándulas paratiroides, o de forma más infrecuente, a un carcinoma paratiroideo. Nuestro objetivo es determinar la utilidad de la hormona paratiroidea intraoperatoria (PTHio) en pacientes con ecografía cervical y centellograma coincidentes preoperatorios, en el HPP por un adenoma simple. Se realizó un estudio retrospectivo, unicéntrico, incluyendo a todos los pacientes sometidos a paratiroidectomía mini-invasiva (PMI) por HPP, por adenoma simple. Definimos estudios coincidentes cuando ambos localizaron el adenoma. La PTHio fue medida en tres ocasiones: en la inducción anestésica, inmediatamente antes y a los 15 minutos de la escisión de la glándula. El éxito se definió como la caída de al menos el 50% del valor máximo de la hormona paratiroidea (PTH) luego de remover la glándula. Se analizaron variables demográficas, intraoperatorias, postoperatorias y la utilidad de la PTHio. Se realizaron un total de 499 paratiroidectomías, de estas, 218 presentaron un adenoma localizado en la ecografía y gammagrafía. La edad fue de 60,1 años y 85% eran mujeres. Luego de 15 minutos de la escisión del adenoma, la PTHio no descendió en nueve pacientes (4,2% OR 1,9 a 7,69%); todos ellos fueron a una exploración cervical bilateral. El valor agregado de la PTHio para la cura de la enfermedad fue de 3,6%. Hubo un 99% de curación de enfermedad. El tiempo operatorio fue de 66,4 minutos y el de espera de la PTHio fue de 31 minutos. La PTHio encareció el procedimiento al doble. La ecografía y el centellograma preoperatorios coincidentes para la localización de un adenoma en HPP podrían evitar la medición de la PTHio durante las PMI. We aim to determine the utility of intraoperative parathyroid hormone (IOPTH) monitoring in patients with matching preoperative ultrasound and mibi SPECT for primary hyperparathyroidism for a single adenoma. All patients who underwent minimally invasive parathyroidectomy (MIP) for pseudohypoparathyroidism (PHP) for a single parathyroid adenoma, were included. An Ultrasound and mibi SPECT were performed in all patients. We defined matching studies when both coincided in the localization of the adenoma. IOPTH was performed in all patients and analyzed in three occasions: a baseline measurement at the anesthetic induction, immediately before, and 15 minutes after gland excision. Success was defined during the third measurement as a drop of IOPTH of at least 50%compared to the previous maximum value after gland excision. Demographics, intraoperative, postoperative variables and the utility of IOPTH monitoring were analyzed. A total of 218 MIP were performed. The average age was 60.1 years and 85% were female. Preoperative ultrasound and mibi SPECT coincided 100%. When the adenoma was localized, 15 minutes after its excision, IOPTH did not decrease in 9 patients (4.2% OR 1.9% - 7.69%); all of them underwent a bilateral neck exploration. The added-value of IOPTH accuracy for disease cure was 3.6%. There was a 99% of cure rate. The mean surgical time was 66.4 minutes and the waiting time for the third IOPTH result was 31minutes. Performing IOPTH monitoring made the surgery about twice more expensive. Preoperative matching ultrasound and mibi SPECT for parathyroid adenoma localization in PHP, could avoid IOPTH monitoring in minimally invasive parathyroidectomies." @default.
