Survival and pulmonary function in stage IA non-small cell lung cancer after sublobar resection versus lobectomy: An updated meta-analysis.

Traditionally, lobectomy was standard for stage IA non-small-cell lung cancer (NSCLC). Recent RCTs suggest sublobar resection's comparable outcomes. Our meta-analysis, incorporating 30 studies (including four RCTs), assessed sublobar resection's efficacy. Employing a random-effects model and I2 statistics for heterogeneity, we found sublobar resection reduced DFS (HR 1.31, p < 0.01) and OS (HR 1.27, p < 0.01) overall. However, RCT subgroup analysis showed no significant differences in DFS (p = 0.28) or OS (p = 0.62). Sublobar resection is a viable option for well-selected patients.

Lobectomy in patients with differentiated thyroid cancer: experience of a Chilean tertiary center.

PURPOSE: Thyroid lobectomy (TL) is an appropriate treatment for up to 4 cm intrathyroidal differentiated thyroid cancer (DTC). There is scarce data regarding TL outside first-world centers. Our aim is to report a cohort of patients with DTC treated with TL in Chile. METHODS: We included DTC patients treated with TL, followed for at least 6 months, characterized their clinicopathological features and classified their risk of recurrence and response to treatment. RESULTS: Eighty-two patients followed for a median of 2.3 years (0.5-7.0). Seventy-three (89%) patients had papillary, 8 (9.8%) follicular and 1 (1.2%) high-grade DTC. The risk of recurrence was low in 56 (68.3%) and intermediate in 26 (31.7%). Eight (9.8%) patients required early completion thyroidectomy and radioiodine. At last follow-up, 52 (70.3%) had excellent, 19 (25.7%) had indeterminate, and 1 (1.4%) had structural incomplete response. CONCLUSION: In a developing country, TL is an adequate option for appropriately selected DTC patients.

Nuevas perspectivas en el tratamiento del cáncer de tiroides de bajo riesgo. Experiencia con la lobectomía tiroidea en una cohorte de 114 pacientes / New perspectives in the management of low-risk thyroid cancer. Experience with thyroid lobectomy in a cohort of 114 patients

RESUMEN Antecedentes: el tratamiento del carcinoma diferenciado de tiroides (CDT) de bajo riesgo es aún motivo de discusión. En las últimas décadas se observó una migración hacia tratamientos personalizados acordes con las características de cada paciente y de cada tumor. Las guías de práctica vigentes habilitan la lobectomía en pacientes seleccionados, con bajo riesgo de recurrencia. Objetivo: describir los resultados en una cohorte de pacientes con CDT de bajo riesgo de recurrencia tratados con lobectomía tiroidea. Material y métodos: estudio observacional descriptivo de una revisión retrospectiva de historias clínicas de 114 pacientes con CDT tratados con lobectomía tiroidea entre enero de 2015 y abril de 2023. Resultados: fueron operados 114 pacientes, con media de edad de 44 años ± 12; 90 (79%) fueron mujeres. La mediana del tamaño tumoral fue de 9,4 mm, RIC (rango intercuartílico 25-75% 7-13 mm), y 103 de los nódulos (90%) fueron ecográficamente sólidos. Solo 2 pacientes con invasión vascular mayor de 4 vasos requirieron completar la tiroidectomía total. No se registraron complicaciones de importancia, salvo una parálisis recurrencial transitoria. Con un seguimiento promedio de 33,4 meses, no se observaron recurrencias locorregionales ni a distancia en la población analizada. Conclusión: la lobectomía tiroidea en el tratamiento del CDT de bajo riesgo tuvo una baja morbilidad sin recurrencias en la serie presentada. La selección rigurosa de los pacientes y la interacción de un equipo multidisciplinario se consideran esenciales para la implementación exitosa de esta metodología terapéutica.

ABSTRACT Background: The treatment of low-risk differentiated thyroid cancer (DTC) is still a matter of debate. Over the past few decades, there has been a shift towards a more personalized approach, tailored to the individual risks of each patient and tumor. The current practice guidelines recommend lobectomy in selected patients, with low risk of recurrence. Objective: To describe the results of thyroid lobectomy in a cohort of patients with DTC with low risk of recurrence. Material and methods: We conducted a descriptive and observational study. The medical records of patients with DTC who underwent thyroid lobectomy between January 2015 and April 2023 were retrospectively reviewed. Results: A total of 114 patients were operated on; mean age was 44 ± 12 years and 90 (79%) were women. The median tumor size was 9.4 mm (IQR 25-75% 7-13 mm), and 103 nodules (90%) were solid on ultrasound. Only 2 patients with vascular invasion involving > 4 vessels required completion thyroidectomy. There were no major complications and only one patient developed temporary recurrent laryngeal palsy. There were no locoregional or distant recurrences during mean follow-up of 33.4 months. Conclusion: Thyroid lobectomy for low-risk DTC had low morbidity and no recurrences in the series presented. The rigorous selection of patients and the interaction of a multidisciplinary team are considered essential for the successful implementation of this therapeutic approach.

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.

Postsurgical outcomes in a cohort of patients with hippocampal sclerosis: Initial experience in a referral epilepsy center in Peru.

Mesial temporal lobe epilepsy, one of the most common forms of epilepsy, is often linked with drug resistance. Surgical intervention is a reliable and safe treatment option, though research into postsurgical outcomes in our locality remains limited. We performed a retrospective observational study included 91 patients with mesial temporal lobe epilepsy and hippocampal sclerosis who had undergone anterior temporal lobectomy between 2012 and 2020 at a surgical epilepsy center located in Lima, Peru. Postoperative outcomes were analyzed using bivariate and multivariate analysis based on the Engel classification. We found that after 12 months of follow-up, 78.65% of the 91 patients achieved an Engel IA classification, while 9.09% attained Engel IB classification and 11.24% were designated as Engel II, with only 1.12% classified as Engel IVA. The median QOLIE31 score was 84 (IQR: 75-90), with 74.16% of the participants successfully reintegrating into academic or employment activities. After 24 months, only 68 patients completed the follow-up, with 69.12% achieving an Engel IA classification. Individuals with a secondary education or higher were more likely to achieve an Engel IA classification at 12 months (OR: 5.11; P = 0.005; CI: 1.63-16.01), after adjusting for sex and age. We concluded that most patients exhibited favorable outcomes after 1 year of follow-up. However, lower educational attainment was linked to worse postsurgical outcomes.

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.

Rey-Osterrieth complex figure test: Comparison of traditional and qualitative scoring systems after unilateral temporal lobectomy.

OBJECTIVE: We compared the performance on the Rey-Osterrieth Complex Figure Test (ROCF) of patients that had undergone unilateral anterior temporal lobectomy under both Taylor's and Loring's scoring systems to identify the sensitivity and specificity of each item for differentiating visuospatial memory deficits. METHOD: We administered the ROCF to evaluate the visual memory of 37 left anterior temporal lobectomy (LATL) and 38 right anterior temporal lobectomy (RATL) patients with unilateral temporal lobe epilepsy who had undergone a standard unilateral anterior temporal lobectomy between 1996 and 2010. Fisher's exact and Qui-Quadrado tests were used to analyze the relationships between the qualitative variables. The Mann-Whitney U test was used to compare the quantitative variables from the right and left sides. RESULTS: RATL patients performed worse than LATL patients based on the total score for delayed recall (DR) (p = 0.012). The scoring system's showed a specificity of 97.2% & 78.9% and sensitivity of 10.5% & 62.2% on DR, for the Taylor and Loring systems respectively. Our detailed analysis of certain items showed that some differed between the groups in terms of the presence/absence, correct reproduction, and errors of those items. Loring' errors I, IV, and X on DR and errors IV and X on immediate recall were more frequent in the RATL group. CONCLUSIONS: The use of these two scoring systems combined may help maximize sensitivity and specificity with clinical populations. Further, our analyses showed that items could be clustered better and different weights could be given to them to maximize sensitivity and specificity.

Outcomes after sublobar resection versus lobectomy in non-small cell carcinoma in situ.

OBJECTIVE: Guidelines for treatment of non-small cell lung cancer identify patients with tumors ≤2 cm and pure carcinoma in situ histology as candidates for sublobar resection. Although the merits of lobectomy, sublobar resection, and lymphoid (LN) sampling, have been investigated in early-stage non-small cell lung cancer, evaluation of these modalities in patients with IS disease can provide meaningful clinical information. This study aims to compare these operations and their relationship with regional LN sampling in this population. METHODS: The National Cancer Database was used to identify patients diagnosed with non-small cell lung cancer clinical Tis N0 M0 with a tumor size ≤2 cm from 2004 to 2017. The χ2 tests were used to examine subgroup differences by type of surgery. Kaplan-Meier method and Cox proportional hazard model were used to compare overall survival. RESULTS: Of 707 patients, 56.7% (401 out of 707) underwent sublobar resection and 43.3% (306 out of 707) underwent lobectomy. There was no difference in 5-year overall survival in the sublobar resection group (85.1%) compared with the lobectomy group (88.9%; P = .341). Multivariable survival analyses showed no difference in overall survival (hazard ratio, 1.044; P = .885) in the treatment groups. LN sampling was performed in 50.9% of patients treated with sublobar resection. In this group, LN sampling was not associated with improved survival (84.9% vs 85.0%; P = .741). CONCLUSIONS: We observed no difference in overall survival between sublobar resection and lobectomy in patients with cTis N0 M0 non-small cell lung cancer with tumors ≤2 cm. Sublobar resection may be an appropriate surgical option for this population. LN sampling was not associated with improved survival in patients treated with sublobar resection.

Unilateral Thyroid Lobectomy as Day Care Procedure: A Cross Sectional Study with Literature Review on the Safety and Cost Effectiveness.

Introduction Thyroid nodules are common globally in almost one fifth of the adult population. The gold standard treatment for thyroid nodule is thyroid lobectomy or total thyroidectomy depending upon the diagnosis. Thyroidectomy has a few known complications but, as per the ATA consensus statement, it is a safe surgery to be done as a day care procedure. Objective To access the feasibility and safety of thyroid lobectomy as a day care surgery and its effect on decreasing overall financial burdens. Methods This retrospective chart review was done from 2006 to 2022. A total of 736 patients underwent thyroid lobectomy among which only 56 were done as day care surgery. Data analysis was done using the IBM SPSS Statistics for Windows, Version 23.0 (IBM Corp., Armonk, NY, USA). Results A total of 40% of the population was male. The mean age of the study population was 42 years. Bethesda II was the most encountered diagnosis, with a rate of 69%. The majority of patients were discharged after 6 hours of postoperative observation. The only complication encountered was seroma, which was seen in two patients. Conclusion Thyroid lobectomy appears to be a safe procedure with a drastic difference in overall cost as a day care procedure. We recommend switching the practice of inpatient thyroid lobectomy to a day care procedure in carefully selected candidates. The major hurdle in day care lobectomy can be approval from insurance.

[ Delay time from diagnosis to surgery in drug-resistant epilepsy]. / Tiempo de retraso desde el diagnóstico hasta la cirugía en la epilepsia refractaria.

Drug-resistant epilepsy, in a good number of cases, can benefit from surgery. It is essential to make a timely referral for the pre-surgical study. We retrospectively reviewed the clinical records of our center from 2011 to 2019. The patients who underwent temporal lobectomy were selected. After performing the data analysis, an average waiting time of 23 years was observed, similar to that observed in other countries of the American continent. There is an evident need to provide strategies to reduce the waiting time for epilepsy surgery in patients who benefit from the intervention.

La epilepsia refractaria, en una buena parte de los casos, puede beneficiarse de cirugía. Es importante realizar una referencia oportuna para el estudio prequirúrgico. Se revisaron de forma retrospectiva los registros clínicos de nuestro centro desde el año 2011 al 2019 y se seleccionaron a los pacientes sometidos a lobectomía temporal. Tras realizar el análisis de los datos se objetivó un tiempo de espera medio de 23 años, similar a lo observado en otros países del continente americano. Existe una necesidad evidente de proporcionar estrategias para disminuir el tiempo de espera para la cirugía de epilepsia en los pacientes que se beneficien de la intervención.

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.

Frequency of Thyroid Gland Invasion by Laryngeal Squamous Cell Carcinoma: The Role of Subglottic Extension

Abstract Introduction Management of the thyroid gland during laryngectomy has been controversial. The primary tumor may invade the thyroid gland by direct invasion or lymphovascular spread. Hypothyroidism and hypoparathyroidism are potential risks when lobectomy or total thyroidectomy are performed simultaneously. Objective To report the frequency of thyroid gland involvement by primary laryngeal squamous cell carcinoma in patients undergoing laryngectomy and to identify possible risk factors for thyroid gland involvement so that judicious excision of thyroid gland can be attained. Methods We performed a retrospective review of 9 years. Data was collected from medical records of patients dated from December 2009 to October 2018. All patients with laryngeal cancer who underwent laryngectomy with lobectomy or total thyroidectomy were included in the present study. Results We reviewed 151 laryngectomy records. A total of 130 surgeries included the thyroid gland with the excised specimen and were available for analysis. There were 124 males and 6 females. The mean age was 59.4 years old. The glottis was the most common subsite involved, in 70 patients, followed by 38 transglottic, 16 supraglottic and 03 subglottic tumors. On histology, 12 out of 130 excised thyroid glands were involved by squamous cell carcinoma. Only subglottic involvement (p = 0.01) was significantly associated with thyroid gland invasion (TGI). Type of laryngectomy, subsite of the primary tumor, thyroid cartilage involvement, neck nodal metastases, and perineural and lymphatic invasion by the primary tumor were not associated with TGI. Conclusion Only subglottic involvement is associated with TGI; therefore, preoperative and intraoperative assessment is necessary prior to considering excision of the thyroid gland.

Obesity in cases undergoing the surgical procedure of lung lobectomy: risk or benefit?

SUMMARY OBJECTIVE: The aim of the study was to evaluate the effect of body mass index on patients' short-term results following lung lobectomy. METHODS: In this retrospective study, we compared the perioperative and short-term postoperative results of obese (BMI≥30 kg/m2) versus non-obese patients (BMI<30 kg/m2) who underwent anatomical lung resection for cancer. The two groups had the same distribution of input risk factors and the same ratio of surgical approaches (thoracoscopy vs. thoracotomy). RESULTS: The study included a total of 144 patients: 48 obese and 96 non-obese patients. Both groups had the same ratio of thoracoscopic vs. thoracotomy approach (50/50%), and were comparable in terms of demographics and clinical data. The g roups did not significantly differ in the frequency of perioperative or postoperative complications. Postoperative morbidity was higher among non-obese patients (34.4 vs. 27.1%), but this difference was not statistically significant (p=0.053). Hospital stay was similar in both study groups (p=0.100). Surgery time was significantly longer among obese patients (p=0.133). Postoperative mortality was comparable between the study groups (p=0.167). CONCLUSIONS: Obesity does not increase the frequency of perioperative and postoperative complications in patients after lung lobectomy. The slightly better results in obese patients suggest that obesity may have some protective role.

Lobectomía por cirugía torácica videoasistida en el Centro Nacional de Cirugía de Mínimo Acceso / Lobectomy for Video-Assisted Thoracic Surgery at the National Center for Minimal Invasive Surgery

Introducción: La tasa de mortalidad de los tumores malignos de tráquea, bronquios y pulmón ocupa el segundo lugar en hombres y el primero en las mujeres. Según el anuario estadístico, hubo 5580 muertes por esta causa en 2020, con una tasa de mortalidad general en los hombres de 61,6 y de 38,1 en la mujer por 100 000 habitantes. Para el tratamiento del cáncer pulmonar en estadios tempranos la cirugía torácica videoasistida ha demostrado su seguridad y efectividad, con una baja morbilidad y una menor estancia posoperatoria. Objetivo: Mostrar los resultados de la lobectomía por cirugía torácica videoasistida en el Centro Nacional de Cirugía de Mínimo Acceso. Métodos: Se realizó un estudio prospectivo en una serie consecutiva de 29 pacientes operados con el diagnóstico de nódulo pulmonar. Para la obtención de la información se confeccionó una planilla de recolección para este fin y en todo momento se contó con el consentimiento informado de los pacientes. Se evaluaron las variables durante el pre, intra y posoperatorio. Resultados: Del total de 57 casos portadores de nódulos pulmonares, se realizó lobectomía por cirugía torácica videoasistida en 29, para un 50,9 por ciento; el 80 por ciento estaban en etapas I y II según el pTNM. Hubo un 31 por ciento de complicaciones y el índice de conversión fue del 20,7 por ciento. Conclusiones: La lobectomía por cirugía torácica video asistida es una técnica segura y de eficacia demostrada, factible de generalizar en nuestro medio(AU)

Introduction: The mortality rate of malignant tumors of the trachea, bronchi and lung ranks second in men and first in women. According to the Health Statistics Yearbook, there were 5,580 deaths from this cause in 2020, with a general mortality rate for men of 61.6 and 38.1 for women per 100,000 inhabitants. For the treatment of lung cancer in early stages, video-assisted thoracic surgery has demonstrated its safety and effectiveness, with low morbidity and a shorter postoperative stay. Objective: To show the results of video-assisted thoracic surgery lobectomy at the National Center for Minimal Invasive Surgery. Methods: A prospective study was carried out in a consecutive series of 29 patients operated on with a diagnosis of pulmonary nodule. A collection form was prepared to obtain the information and the informed consent of the patients was obtained at all times. The variables were evaluated during the pre, intra and postoperative period. Results: Fifty seven (57) cases with pulmonary nodules formed the total of this study. Twenty nine of them (29) underwent lobectomy by video-assisted thoracic surgery (50.9 percent). 80 percent were in stages I and II according to pTNM. There were 31 percent complications and the conversion rate was 20.7 percent. Conclusions: Video-assisted thoracic surgery lobectomy is a safe and proven technique, which is feasible to generalize in our setting(AU)

Pneumotórax secundário a bolha pulmonar em cão / Pneumothorax secondary to a pulmonary bullae in a dog

Background: Pulmonary bullae are thin-walled cavitary lesions within the subpleural parenchyma. They are a result of thedestruction, dilatation and coalescence of bordering alveoli and their rupture is the most common cause of pneumothoraxin dogs. Radiographic and CT imaging are excellent tools for identifying and quantifying pneumothorax. Surgical treatment is considered standard for treatment of pneumothorax consequential to pulmonary bullae. The aim of this report wasto describe a case of pneumothorax secondary to pulmonary bullae in a dog.Case: A 5-year-old male crossbreed dog, weighing 11.5 kg, was presented to the Uberaba’s Veterinary Hospital due to becoming easily tired in the previous 3 weeks, and its worsening in the last 2 days by presenting panting. The dog’s guardiandid not witness any traumas, but informed that the animal resided with other 14 dogs and also that it frequently collidedthe thorax against the door when it came down from the bed. Physical examination showed diaphragmatic breathing,inspiratory dyspnea and stridor lung sound. Thoracocentesis revealed presence of air in the pleural cavity and pneumothorax. Radiographic images confirmed this condition. The dog stayed in the hospital and chest drains were placed. Sincethe amount of sucked air did not reduce with time and due to the emergence of subcutaneous emphysema, the dog wentthrough exploratory thoracotomy that revealed impairment of the right caudal lung lobe, proceeding to lobectomy. Thedog stayed in the hospital with chest drains until the contents of the suctions reduced significantly. With the removal ofthe drains, the dog was sent home and had a full recovery. Histopathology of the impaired lung revealed pulmonary bullae.Discussion: The dog from this report presented clinical signs consistent with pneumothorax, such as dyspnea, diaphragmaticbreathing and exercise intolerance. Radiography of the chest region revealed...

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
