Tratamiento quirúrgico de las neoplasias en la glándula parótida / Surgical treatment of the neoplasmsof the parotid gland

Objetivo: Caracterizar a pacientes con diagnóstico de neoplasias en glándula parótida, según el procedimiento quirúrgico efectuado, la técnica de identificación del nervio facial, y la relación de los hallazgos patológicos definitivos con los estudios de muestreo histológico preoperatorio. Métodos: Estudio multidisciplinario, multiinstitucional, descriptivo, cuantitativo y retrospectivo de 26 pacientes con diagnóstico de neoplasias en glándula parótida entre el año 2018 al 2023. Se dividieron de acuerdo a la histología en benignas y malignas. Las distintas frecuencias fueron expresadas en número y porcentaje. Se calculó la sensibilidad y especificidad de la punción con aguja fina como prueba de muestreo histológico. Resultados: Categoría benigna: 16 pacientes (61,5% %). El resto de la serie, diez pacientes, de la categoría de tumores malignos (38,5%). La lobectomía superficial parotídea fue el procedimiento más frecuente en las neoplasias benignas (75%) y malignas (60%). La técnica anterógrada de identificación del nervio facial fue la más común. Entre 25% a 30% de parálisis temporales en ambos grupos. La sensibilidad y especificidad de la punción con aguja fina para el diagnóstico de neoplasias benignas fue de 92,3% y 50%, el porcentaje de falsos negativos de 5,8%. Conclusión: La lobectomía superficial de la glándula parótida y la técnica anterógrada representaron el procedimiento quirúrgico y la técnica de identificación del nervio facial más frecuentemente realizado en ambas categorías. La baja especificidad de la punción con aguja fina y el porcentaje de falsos negativos representaron algunas de las dificultades a afrontar para decidir la extensión del tratamiento quirúrgico(AU)

Metástasis pulmonares aisladas de adenocarcinoma ductal de páncreas: una población con supervivencia prolongada / Isolated pulmonary metastases from pancreatic ductal adenocarcinoma: a population with prolonged survival

RESUMEN La incidencia de metástasis pulmonares aisladas en adenocarcinoma ductal de páncreas es aproximadamente del 13%. La resección de estas metástasis es infrecuente; sin embargo, los pacientes que se presentan únicamente con metástasis pulmonares tienen una mejor supervivencia comparadas con otras localizaciones. Presentamos el caso de una paciente a quien se le realizó una lobectomía pulmonar por metástasis de adenocarcinoma ductal de páncreas. Luego de la resección, el período libre de recurrencia y la supervivencia libre de enfermedad específica fueron de 84 y 152 meses, respectivamente. Consideramos que el siguiente paso en el tratamiento de esta subpoblación es poder seleccionar a los pacientes con una biología tumoral favorable y que una estrategia de tratamiento enérgica estaría justificada.

ABSTRACT The incidence of isolated pulmonary metastases in pancreatic ductal adenocarcinoma is about 13%. Resection of these metastases is uncommon; however, patients presenting only with pulmonary metastases have better survival compared to those with metastases on other locations. We report the case of a female patient who underwent lobectomy for metastases from pancreatic ductal adenocarcinoma. After resection, disease-free interval and specific diseases-free survival were 84 and 152 moths, respectively. We consider that the next step in the treatment of this subpopulation of patients is to select those patients with favorable tumor biology who would benefit from a more aggressive approach.

Surgical treatment of temporal lobe epilepsy: comparative results of selective amygdalohippocampectomy versus anterior temporal lobectomy from a referral center in Brazil / Tratamento cirúrgico da epilepsia do lobo temporal: resultados comparativos da amigdalohipocampectomia seletiva versus lobectomia temporal anterior em um centro de referência no Brasil

Abstract Background Temporal lobe epilepsy (TLE) is a high prevalence neurological disorder. Surgery has emerged as a promising treatment. Objective The objective of this work is to compare the surgical results of anterior temporal lobectomy (ATL) versus selective amygdalohippocampectomy (SAH) in a cohort of 132 patients. Methods We performed a retrospective study of 146 patients operated for TLE from 2008 to 2019. Initially, 13 patients were excluded from the study due to insufficient medical record data or follow-up loss. One patient was excluded from the analysis of the results due to death in the first postoperative week. We used the ILAE scale to classify seizure control after surgery. In patients with left hippocampal sclerosis, SAH was performed and in right temporal lobe epilepsy, ATL was the approach of choice. Results The mean follow-up time after surgery was 57.2 months (12-137). In our data analysis, we found that the group of patients undergoing ATL had a higher prevalence of being completely seizure-free (ILAE I) (57.1% versus 31%) and a higher rate of satisfactory seizure control (88.6% versus 69.3%) p = 0,006, when compared with patients undergoing SAH. Conclusions The literature is still controversial about seizure control concerning the technique used due to the lack of a robust methodology. Our data analysis identified the superiority of ATL over SAH in seizure outcomes. ATL may be the best option for adequately controlling seizures with minimal additional morbidity in countries with a cost limitation for extended propaedeutics.

Resumo Antecedentes A epilepsia do lobo temporal (TLE) é uma desordem neurológica de alta prevalência. A cirurgia surgiu como um tratamento promissor. Objetivo O objetivo deste trabalho é comparar os resultados da lobectomia temporal anterior (ATL) versus amigdalohipocampectomia seletiva (SAH) em uma coorte de 132 pacientes. Métodos Realizamos um estudo retrospectivo de 146 pacientes operados por TLE de 2008 a 2019. Inicialmente, 13 pacientes foram excluídos por insuficiência de dados em prontuário ou perda de seguimento. Um paciente foi excluído da análise por óbito na primeira semana de pós-operatório. Usamos a escala ILAE para classificar o controle das crises após a cirurgia. Em pacientes com esclerose hipocampal à esquerda, foi realizada a SAH, e na epilepsia do lobo temporal à direita, a ATL foi a abordagem de escolha. Resultados O tempo médio de seguimento após a cirurgia foi de 57,2 meses (12-137). Em nossa avaliação, encontramos que o grupo de pacientes submetidos à ATL apresentou maior prevalência de ausência total de crises (ILAE I) (57,1% versus 31%) e maior taxa de controle satisfatório da epilepsia (88,6% versus 69,3%) p = 0,006, quando comparado ao grupo submetido à SAH. Resultados A literatura ainda é controversa em relação à redução das crises de acordo com a técnica utilizada devido a falta de uma metodologia robusta. Nosso estudo identificou superioridade da ATL sobre a SAH nos desfechos convulsivos. ATL pode ser a melhor opção para controlar adequadamente as convulsões com morbidade adicional mínima em países com limitação de custo para propedêutica estendida.

Tiroidectomía endoscópica transoral por vía vestibular: resultados de los 53 primeros casos / Transoral endoscopic thyroidectomy vestibular approach: Results after 53 first cases

Introducción: La tiroidectomía endoscópica transoral por vía vestibular permite el acceso al tiroides sin cicatrices visibles y con el mejor resultado cosmético posible. Métodos: Estudio observacional prospectivo de 53 pacientes sometidos a tiroidectomía endoscópica transoral desde julio de 2017 hasta junio de 2021. Resultados: Cincuenta y dos casos (98,1%) fueron mujeres con una mediana de edad de 44 años. El nódulo tiroideo fue la indicación quirúrgica más frecuente (73,6%). Se realizaron 42 lobectomías,11 tiroidectomías totales y en 4 casos se asoció vaciamiento ganglionar del compartimento central izquierdo. La mediana de tiempo para la colocación de trócares fue de 14min, y para la lobectomía, la tiroidectomía total y el vaciamiento ganglionar del compartimento central izquierdo, de 80, 140 y 30min, respectivamente. La mediana de estancia hospitalaria fue de 2 días. Cuatro pacientes presentaron disfonía (7,5%), pero la laringoscopia solo confirmó lesión del recurrente en 2 casos, una de ellas permanente (1,6%). En los pacientes con tiroidectomía total la frecuencia de hipoparatiroidismo transitorio fue del 18,2% y el permanente de 0%. Dentro de las complicaciones asociadas al abordaje, en todos los pacientes se presentó anestesia de la región mentoniana transitoria y de intensidad variable. Conclusiones: La cirugía transoral es un abordaje de aplicación reciente en nuestra unidad. Los resultados en nuestros primeros pacientes muestran que es un abordaje eficaz y seguro cuando se realiza en pacientes bien seleccionados, con el mejor resultado cosmético y con complicaciones nuevas, asociadas al abordaje, transitorias en nuestra serie.

Introduction: Transoral endoscopic thyroidectomy through vestibular approach allows access to the thyroid with the best cosmetic results as there are no visible scars. Methods: Here we present a prospective observational study of 53 patients which underwent transoral endoscopic thyroidectomy from July 2017 to June 2021. Results: Fifty-two cases (98.1%) were women (median age 44 years old). Thyroid nodule was the main surgical indication accounting 73.6% of cases. We performed 42 lobectomies and 11 total thyroidectomies; 4 left central neck dissection were also associated. The median surgical time for port placement was 14min, and for lobectomy, total thyroidectomy and left central neck dissection were 80, 140 and 30min, respectively. The median of hospital stay was 2 days. Dysphonia was present in 4 patients (7.5%); however, laryngoscopy only confirmed laryngeal nerve impairment in 2 cases, one of them classified as permanent (1.6%). In those patients that underwent total thyroidectomy, the rate of transient hypoparathyroidism was 18.2% whereas permanent was 0%. Regarding complications associated to the new approach, transient chin numbness appeared in all patients with a variable degree of intensity. Conclusions: Transoral surgery is a recent approach in our unit. Our results, based on the first 53 patients, show that it is a safe and effective approach when performed in appropriately selected patients offering the best cosmetic result. Besides, new complications associated to the approach has been shown to be transient. (AU)

Factores predictores de estancia hospitalaria prolongada tras resección pulmonar anatómica / Predictive factors of prolonged postoperative length of stay after anatomic pulmonary resection

Introducción: El objetivo de este estudio es crear un modelo predictivo de estancia postoperatoria prolongada (EPP) en pacientes sometidos a resección pulmonar anatómica, validarlo en una serie externa y evaluar la influencia de la EPP en el reingreso y la mortalidad a 90 días. Métodos: Se incluyeron todos los pacientes registrados en la base de datos del GEVATS dados de alta tras la intervención. Definimos la EPP como la permanencia postoperatoria en días por encima del percentil 75 de estancia de todos los pacientes de la serie. Se realizó un análisis univariable y multivariable mediante regresión logística y el modelo fue validado en una cohorte externa. Se analizó la posible asociación entre la EPP y el reingreso y la mortalidad a 90 días. Resultados: Se incluyeron en el estudio 3473 pacientes. La mediana de estancia postoperatoria fue de 5 días (RIQ:4-7). Ochocientos quince pacientes tuvieron una EPP (≥8 días), de los que el 79,9% presentaron complicaciones postoperatorias. El modelo final incluyó como variables: edad, IMC, sexo varón, VEF1%ppo, DLCO%ppo y toracotomía; el AUC en la serie de derivación fue de 0,684 (IC95%: 0,661-0,706) y en la de validación de 0,73 (IC95%: 0,681-0,78). Se encontró una asociación significativa entre la EPP y el reingreso (p<0,000) y la mortalidad a 90 días (p<0,000). Conclusiones: Las variables edad, IMC, sexo varón, VEF1%ppo, DLCO%ppo y toracotomía afectan a la EPP. La EPP se asocia con un incremento del riesgo de reingreso y mortalidad a 90 días. El 20% de las EPP no se relacionan con la ocurrencia de complicaciones postoperatorias. (AU)

Introduction: The objective of this study is to create a predictive model of prolonged postoperative length of stay (PLOS) in patients undergoing anatomic lung resection, to validate it in an external series and to evaluate the influence of PLOS on readmission and 90-day mortality. Methods: All patients registered in the GEVATS database discharged after the intervention were included. We define PLOS as the postoperative stay in days above the 75th percentile of stay for all patients in the series. A univariate and multivariate analysis was performed using logistic regression and the model was validated in an external cohort. The possible association between PPE and readmission and mortality at 90 days was analyzed. Results: 3473 patients were included in the study. The median postoperative stay was 5 days (IQR: 4–7). 815 patients had PLOS (≥8 days), of which 79.9% had postoperative complications. The final model included as variables: age, BMI, male sex, ppoFEV1%, ppoDLCO% and thoracotomy; the AUC in the referral series was 0.684 (95% CI: 0.661–0.706) and in the validation series was 0.73 (95% CI: 0.681–0.78). A significant association was found between PLOS and readmission (p<.000) and 90-day mortality (p<.000). Conclusions: The variables age, BMI, male sex, ppoFEV1%, ppoDLCO% and thoracotomy affect PLOS. PLOS is associated with an increased risk of readmission and 90-day mortality. 20% of PLOS are not related to the occurrence of postoperative complications. (AU)

Transoral endoscopic thyroidectomy vestibular approach: Results after 53 first cases.

INTRODUCTION: Trans Oral Endoscopic Thyroidectomy through Vestibular Approach (TOETVA) allows access to the thyroid with the best cosmetic results as there are no visible scars. METHODS: Here we present a prospective observational study of 53 patients which underwent TOETVA from July 2017 to June 2021. RESULTS: Fifty-two cases (98.1%) cases were women (median age 44 years old). Thyroid nodule was the main surgical indication accounting 73.6% of cases. We performed 42 lobectomies and 11 total thyroidectomies; 4 left Central Neck Dissection (CND) were also associated. The median surgical time for port placement was 14 min and for lobectomy, total thyroidectomy and left CND were 80, 140 and 30 min, respectively. The median of hospital stay was 2 days. Dysphonia was present in 4 patients; however, laryngoscopy only confirmed laryngeal nerve impairment in 2 cases, one of them classified as permanent (1.6%). In those patients that underwent total thyroidectomy, the rate of transient hypoparathyroidism was 18.2% whereas permanent was 0%. Regarding complications associated to the new approach, transient chin numbness appeared in all patients with a variable degree of intensity. CONCLUSTIONS: Transoral surgery is a recent approach in our Unit. Our results, based on the first 53 patients, show that it is a safe and effective approach when performed in appropriately selected patients offering the best cosmetic result. Besides, new complications associated to the approach has been shown to be transient.

Caracterización de pacientes sometidos a cirugía torácica atendidos en la unidad de cuidados intensivos

Introducción: La cirugía torácica representa una de las causas de ingreso más frecuentes en la unidad de cuidados intensivos. Objetivo: Describir las variables edad, sexo, diagnóstico preoperatorio, técnica quirúrgica empleada, analgesia, complicaciones y evolución de los pacientes sometidos a cirugía torácica, en una unidad de cuidados intensivos. Métodos: Se realizó un estudio de corte transversal de 42 pacientes de cirugía torácica, ingresados en una unidad de cuidados intensivos. Se estudiaron las variables edad, sexo, diagnóstico, técnica quirúrgica empleada, analgesia, complicaciones y evolución, con las cuales se realizó un análisis de frecuencias. Resultados: El grupo etario predominante fue el de mayores de 60 años (42,9 %). El sexo representativo fue el masculino (78,5 %). El diagnóstico más frecuente para cirugía torácica fue el cáncer de pulmón (47,6 %). La técnica más empleada fue la lobectomía (28,6 %). La dipirona fue la analgesia más utilizada (35,7 %). La mayoría de los pacientes no presentó complicaciones (83,3 %). Prevalecieron los pacientes egresados vivos (97,6 %) sobre los fallecidos (2,4 %). Conclusiones: El cáncer de pulmón representó la causa más frecuente de cirugía torácica en ambos sexos, en consecuencia, la toracotomía con lobectomía fue la técnica más empleada. Este tipo de intervención siempre implica alteraciones funcionales que pueden ser inaparentes y controlables; el manejo postoperatorio en la unidad de cuidados intensivos de estos pacientes determinará en gran medida su evolución.

Introduction: Thoracic surgery represents one of the most frequent causes of admission to the intensive care unit. Objective: To describe the variables age, sex, preoperative diagnosis, surgical technique used, analgesia, complications and evolution of patients undergoing thoracic surgery in an intensive care unit. Methods: A cross-sectional study of 42 thoracic surgery patients admitted to an intensive care unit was conducted. The variables age, sex, diagnosis, surgical technique used, analgesia, complications and evolution were studied, with which a frequency analysis was performed. Results: The predominant age group was older than 60 years (42.9 %). The representative sex was male (78.5 %). The most frequent diagnosis for thoracic surgery was lung cancer (47.6 %). The most used technique was lobectomy (28.6 %). Dipyrone was the most used analgesia (35.7 %). Most of the patients did not present complications (83.3 %). Patients discharged alive prevailed (97.6 %) over deceased patients (2.4 %). Conclusions: Lung cancer represented the most frequent cause of thoracic surgery in both sexes. Consequently, thoracotomy with lobectomy was the most used technique. This type of intervention always implies functional alterations that can be inapparent and controllable; Postoperative management in the intensive care unit of these patients will largely determine their evolution.

Similar outcomes after newly implemented rats approach compared to standard vats for anatomical lung resection. A propensity-score matched analysis / Resultados similares de un abordaje robótico (RATS) recientemente implementado comparado con un abordaje VATS convencional para resecciones pulmonares anatómicas: análisis de datos emparejados por puntuación de propensión

Introduction Outcomes after the introduction of surgical innovations can be impaired by learning periods. The aim of this study is to compare the short-term outcomes of a recently implemented RATS approach to a standard VATS program for anatomical lung resections. Methods Retrospective review of consecutive patients undergoing pulmonary anatomical resection through a minimally invasive approach since RATS approach was applied in our department (June 01, 2018, to November 30, 2019). Propensity score matching was performed according to patients’ age, gender, ppoFEV1, cardiac comorbidity, type of malignancy, and type of resection. Outcome evaluation includes: overall morbidity, significant complications (cardiac arrhythmia, pneumonia, prolonged air leak, and reoperation), 30-day mortality, and length of hospital stay. Data were compared by two-sided chi-square or Fisher's exact test for categorical and Mann–Whitney U test for continuous variables. Results A total of 273 patients (206 VATS, 67 RATS) were included in the study. After propensity score matching, data of 132 patients were analyzed. The thirty-days mortality was nil. Overall morbidity (RATS: 22.4%, VATS: 29.2%; p=0.369), major complications (RATS: 9% vs VATS: 9.2%; p=0.956) and the rates of specific major complications (cardiac arrhythmia RATS: 4.5%, VATS: 4.6%, p=1; pneumonia RATS:0%, VATS:4.6%, p=0.117; prolonged air leak RATS: 7.5%; VATS: 4.6%, p=0.718) and reoperation (RATS: 3%, VATS: 1.5%, p=1) were comparable between both groups. The median length of stay was 3 days in both groups (p=0.101) (AU)

Introducción La introducción de innovaciones quirúrgicas se asocia con períodos de aprendizaje que pueden afectar a los resultados. El objetivo de este estudio es comparar los resultados postoperatorios de un abordaje RATS para resecciones pulmonares anatómicas implementado recientemente frente a los de un abordaje VATS convencional. Métodos Revisión retrospectiva de los pacientes sometidos a resección pulmonar anatómica mediante un abordaje mínimamente invasivo en nuestro centro desde el inicio del programa de cirugía RATS (junio de 2018) hasta noviembre de 2019. Los pacientes fueron emparejados por puntuación de propensión según variables de riesgo. Los resultados analizados fueron: morbilidad global, complicaciones (mayores, arritmia, neumonía, fuga aérea prolongada y reintervención), mortalidad a los 30 días y estancia hospitalaria. Los datos se compararon mediante la prueba de chi-cuadrado o la exacta de Fisher para variables categóricas y la prueba de U de Mann-Whitney para variables continuas. Resultados Se incluyeron en el estudio 273 pacientes (206 VATS, 67 RATS). Tras el emparejamiento, se analizaron los datos de 132 pacientes. La mortalidad a los 30 días fue nula. La morbilidad global (RATS: 22,4%, VATS: 29,2%; p=0,369), complicaciones mayores (RATS: 9%, VATS: 9,2%; p=0,956), arritmia (RATS: 4,5%, VATS: 4,6%, p=1); neumonía (RATS: 0%, VATS: 4,6%, p=0,117); fuga aérea prolongada (RATS: 7,5%; VATS: 4,6%, p=0,718) y reintervención (RATS: 3%, VATS: 1,5%, p=1) fueron comparables entre ambos grupos. La mediana de la estancia hospitalaria fue de 3 días en ambos grupos (p=0,101). Conclusiones Un programa RATS para resecciones pulmonares anatómicas puede implementarse de manera segura por cirujanos experimentados en VATS sin aumentar los índices de morbilidad (AU)

Retrospective analysis of low-risk differentiated thyroid tumours: is lobectomy the adequate approach? / Kis rizikójú differenciált pajzsmirigydaganatok retrospektív analízise: lobectomia a megfelelo választás?

Introduction: According to the recommendation of the American Thyroid Association 2015 guideline, the treatment of 1-4 cm (T1b-2) low-risk differentiated thyroid cancer (DTC) is lobectomy without radioiodine therapy. Objective: Retrospective analysis of multifocality in surgical and histological data of T1-2 patients living on moderate iodine intake. Methods: Analysis of the pathological characterisation of 81 low-risk (T1-2) DTC patients who underwent total thy-roidectomy. Patients were treated at Flor Ferenc Hospital, Kistarcsa, Hungary, between 2013 and 2019. Results: 64 patients had T1, while 17 patients had T2 status. 65/81 (80.2%) patients had papillary, and 16/81 (19.8%) had follicular subtype. Lymph node metastasis was detected up to 18.4% in papillary and 18% in follicular patients. Multifocal tumours were detected in 25% (16/64) of T1 patients, of these 10.9% (7/64) was unilateral and 14.1% (9/64) was bilateral. Multifocal tumours were detected in 11.7% (2/17) of T2 patients; both were bilateral. Distribution of T1-2 bilateral multifocal patients (11/81; 13.5%) was n = 3 T1a-, n = 6 T1b and n = 2 T2 stadium, from these 10 patients received radioiodine treatment. The sizes of contralateral tumours were <5 mm in 9 patients, and >5 mm in 2 patients. Conclusions: Due to the frequent (13.5%) bilateral multifocality in T1-2 DTC patients, we suggest total thyroidec-tomy instead of lobectomy. After lobectomy, the follow-up of the contralateral tumours is almost impossible by ul-trasonography due to the small tumour size (on average 2.8 mm) and frequently detected benign nodules; therefore the multifocality might remain undetected, which can distort the plan for adjuvant treatment.

Similar outcomes after newly implemented rats approach compared to standard vats for anatomical lung resection. A propensity-score matched analysis.

INTRODUCTION: Outcomes after the introduction of surgical innovations can be impaired by learning periods. The aim of this study is to compare the short-term outcomes of a recently implemented RATS approach to a standard VATS program for anatomical lung resections. METHODS: Retrospective review of consecutive patients undergoing pulmonary anatomical resection through a minimally invasive approach since RATS approach was applied in our department (June 01, 2018, to November 30, 2019). Propensity score matching was performed according to patients' age, gender, ppoFEV1, cardiac comorbidity, type of malignancy, and type of resection. Outcome evaluation includes: overall morbidity, significant complications (cardiac arrhythmia, pneumonia, prolonged air leak, and reoperation), 30-day mortality, and length of hospital stay. Data were compared by two-sided chi-square or Fisher's exact test for categorical and Mann-Whitney U test for continuous variables. RESULTS: A total of 273 patients (206 VATS, 67 RATS) were included in the study. After propensity score matching, data of 132 patients were analyzed. The thirty-days mortality was nil. Overall morbidity (RATS: 22.4%, VATS: 29.2%; p=0.369), major complications (RATS: 9% vs VATS: 9.2%; p=0.956) and the rates of specific major complications (cardiac arrhythmia RATS: 4.5%, VATS: 4.6%, p=1; pneumonia RATS:0%, VATS:4.6%, p=0.117; prolonged air leak RATS: 7.5%; VATS: 4.6%, p=0.718) and reoperation (RATS: 3%, VATS: 1.5%, p=1) were comparable between both groups. The median length of stay was 3 days in both groups (p=0.101). CONCLUSIONS: A RATS program for anatomical lung resection can be implemented safely by experienced VATS surgeons without increasing morbidity rates.

Predictive factors of pathological complete response after induction (ypT0N0M0) in non-small cell lung cancer and short-term outcomes: Results of the Spanish Group of Video-assisted Thoracic Surgery (GE-VATS).

INTRODUCTION: To analyze the predictors of pCR in NSCLC patients who underwent anatomical lung resection after induction therapy and to evaluate the postoperative results of these patients. METHODS: All patients prospectively registered in the database of the GE-VATS working group undergone anatomic lung resection by NSCLC after induction treatment and recruited between 12/20/2016 and 3/20/2018 were included in the study. The population was divided into two groups: patients who obtained a complete pathological response after induction (pCR) and patients who did not obtain a complete pathological response after induction (non-pCR). A multivariate analysis was performed using a binary logistic regression to determine the predictors of pCR and the postoperative results of patients were analyzed. RESULTS: Of the 241 patients analyzed, 36 patients (14.9%) achieved pCR. Predictive factors for pCR are male sex (OR: 2.814, 95% CI: 1.015-7.806), histology of squamous carcinoma (OR: 3.065, 95% CI: 1.233-7.619) or other than adenocarcinoma (OR: 5.788, 95% CI: 1.878-17.733) and induction therapy that includes radiation therapy (OR: 4.096, 95% CI: 1.785-9.401) and targeted therapies (OR: 7.625, 95% CI: 2.147-27.077). Prevalence of postoperative pulmonary complications was higher in patients treated with neoadjuvant chemo-radiotherapy (p = 0.032). CONCLUSIONS: Male sex, histology of squamous carcinoma or other than ADC, and induction therapy that includes radiotherapy or targeted therapy are positive predictors for obtaining pCR. Induction chemo-radiotherapy is associated with a higher risk of postoperative pulmonary complications.

Rehabilitación neuropsicológica en pacientes pre y posquirúrgicos de lobectomía temporal por epilepsia fármaco resistente / Neuropsychological rehabilitation in pre- and post-surgical temporal lobectomy patients for drug-resistant epilepsy

Introducción. La epilepsia del lóbulo temporal suele producir déficits mnésicos, atencionales y del lenguaje. En la mayoría de los casos, se trata con fármacos an-tiepilépticos, pero falla en un tercio de ellos. Por tal razón, una opción terapéutica es la lobectomía temporal, que contribuye a menguar las crisis. Sin embargo, los procedimientos quirúrgicos pueden conllevar secuelas, entre ellas consecuencias a nivel cognitivo. Para contrarrestar dichos efectos, se acostumbra llevar a cabo una rehabilitación neuropsicológica que va en pro de recuperar, fortalecer y sostener en el tiempo habilidades que ya venían afectándose desde antes de la cirugía. Objetivo. Brindar una reflexión en torno a la intervención neuropsicológica de la epilepsia en el lóbulo temporal. Método. La reflexión sobre el tema parte de un interés clínico y posteriormente se fue ampliando a partir de la revisión de la literatura en diferentes bases de datos como PubMed, Medline y Scopus entre los años 2000 y 2021. Reflexión. Son amplias las opciones terapéuticas a nivel neuropsicológico y pueden contribuir de manera positiva en la recuperación del paciente, por lo cual los profe-sionales requieren conocer las posibilidades de ello para poder utilizar las estrategias más adecuadas según cada caso y brindar opciones que beneficien la calidad de vida, teniendo en cuenta que ninguna es más efectiva que otra. Conclusión. Como resultado, se presenta un panorama general de la rehabilitación neuropsicológica en pacientes pre y posquirúrgicos con lobectomía, haciendo énfasis en la rehabilitación neuropsicológica tradicional y la rehabilitación basada en inteli-gencia artificial, realidad virtual y computación

Introduction. Temporal lobe epilepsy usually produces mnestic, attentional, and language deficits. In most cases, it is treated with antiepileptic drugs, but one third of them fail, so one therapeutic option is temporal lobectomy, which helps to reduce seizures. However, surgical procedures can have sequelae, including cognitive con-sequences. To counteract these effects, neuropsychological rehabilitation is usually carried out in order to recover, strengthen, and sustain in time skills that were already affected before the surgery. Objective. To provide a reflection on the neuropsychological intervention of tem-poral lobe epilepsy. Method. The reflection on the subject starts from a clinical interest and was sub-sequently expanded from the review of the literature in different databases such as PubMed, Medline, and Scopus between 2000 and 2021. Reflection. There are many therapeutic options at the neuropsychological level and they can contribute positively to the patient's recovery, so professionals need to know the possibilities in order to use the most appropriate strategies according to each case and provide options that benefit the quality of life, taking into account that none is more effective than the other one.Conclusion. As a result, an overview of neuropsychological rehabilitation in pre- and post-surgical patients with lobectomy is presented, with emphasis on traditional neuropsychological rehabilitation and rehabilitation based on artificial intelligence, virtual reality, and computation

Alteraciones psiquiátricas tras lobectomía temporal anterior: reporte de casos / Psychiatric alterations after previous temporal lobectomy: Report of cases and review

RESUMEN Introducción: La lobectomía temporal anterior (LTA) es un procedimiento quirúrgico comúnmente utilizado para el tratamiento de la epilepsia del lóbulo temporal refractario al tratamiento médico, con altas tasas de éxito en el control de las crisis. Sin embargo, se ha descrito una asociación importante con enfermedades psiquiátricas que puede afectar al resultado posquirúrgico en estos pacientes. Métodos: Se exponen 2 casos representativos de pacientes que sufrieron complicaciones psiquiátricas en el posoperatorio de lobectomía temporal anterior, a pesar del control exitoso de las crisis. Resultados: Un varón sin antecedentes de enfermedad mental que sufre un episodio depresivo mayor en el periodo posoperatorio mediato, y una mujer con psicosis previa que evidencia exacerbación de su afección como complicación quirúrgica. Conclusiones: La enfermedad psiquiátrica se puede presentar en pacientes posoperatorios de epilepsia de lóbulo temporal tanto con antecedentes de enfermedad mental como sin ellos. Las alteraciones más frecuentes reportadas son depresión, ansiedad, psicosis y trastornos de la personalidad. La inclusión de evaluaciones psiquiátricas en los protocolos prequirúrgicos y posquirúrgicos pueden llevar a una mejora en el pronóstico de los resultados neurológicos y mentales de los pacientes sometidos a la intervención.

ABSTRACT Introduction: Anterior temporal lobectomy (LTA) is a surgical procedure commonly used for the treatment of temporal lobe epilepsy refractory to medical management, with high success rates in the control of seizures. However, an important association with psychiatric illnesses has been described that can alter the postoperative outcome in these patients. Methods: A series of 2 cases of patients who, despite successful crisis control, developed psychiatric complications in the postoperative period of anterior temporal lobectomy. Results: The cases included a male patient with no history of previous mental illness, who developed a major depressive episode in the postoperative period, and a female patient with previous psychosis who presented as a surgical complication exacerbation of psychosis, diagnosed with paranoid schizophrenia. Conclusions: Psychiatric disorders can occur in postoperative temporal lobe epilepsy patients with or without a history of mental illness. The most frequent alterations reported are depression, anxiety, psychosis and personality disorders. The inclusion of psychiatric evaluations in the pre- and post-surgical protocols can lead to an improvement in the prognosis of the neurological and mental outcomes of the patients undergoing the intervention.
