ABSTRACT

INTRODUCCIÓN: en la actualidad no existe un consenso respecto al manejo de los nódulos pulmonares subsólidos (NPSS). OBJETIVO: describir los resultados del manejo quirúrgico de los NPSS, basados en un algoritmo local. MATERIAL Y MÉTODOS: estudio descriptivo de corte transversal. Se revisaron las fichas clínicas electrónicas de los pacientes operados por NPSS, sugerentes de ser malignos, a juicio de un equipo multidisciplinario, entre enero de 2014 y enero de 2018, en el Departamento de Cirugía de Adultos de Clínica Las Condes. RESULTADOS: se estudió un total de 35 pacientes. La edad promedio fue de 65,8 años. El tamaño promedio de los nódulos fue de 15 mm. Todos los pacientes fueron abordados por cirugía videotoracoscópica asistida. El 88,6% de las biopsias demostró la presencia de una neoplasia maligna. CONCLUSIONES: la adopción de un algoritmo local, instituido por un equipo multidisciplinario, es una alternativa para el manejo adecuado de los portadores de NPSS.


BACKGROUND: Nowadays, there is no consensus in the management of pulmonary subsolid nodules (SSNs). AIM: describe the results of surgical management of SSNs, based on institutional algorithm. MATERIAL AND METHODS: cross-sectional, descriptive study, with revision of clinical electronic records, that included all patients intervened for SSNs, suggestive of malignancy, by the judgment of a multi-disciplinary team, from January 2014 to January 2018 at the Department of Adult Surgery, Clinica Las Condes. RESULTS: 35 patients were studied. The average age was 65.8 years. The average size of the nodules was 15 mm. All patients were approached by video-assisted thoracoscopic surgery. 88.6% of biopsies turned out to be malignant neoplasm. CONCLUSIONS: the acquisition of a local algorithm established by a multidisciplinary team is an appropriate alternative for the management of the patients with SSNs.

ABSTRACT

Resumen Introducción: Uno de los mayores avances de las últimas décadas en la cirugía de tórax ha sido el desarrollo de la cirugía mínimamente invasiva. Objetivos: Describir la experiencia en videotoracoscopía (VATS) Uniportal de miembros del equipo de Cirugía de Tórax de la Universidad de Chile en 2 campos clínicos, (Clínica Las Condes y Hospital Clínico de la Universidad de Chile). Materiales y Método: Se estudiaron 105 pacientes sometidos a VATS uniportal entre enero de 2016 y enero de 2019. Los datos se analizaron de manera retrospectiva considerando variables demográficas (edad, sexo) y clínicas (diagnóstico, cirugía, estadía hospitalaria, días de pleurostomía, conversión y complicaciones). Resultados: De las 105 cirugías realizadas, 28 (26,6%) correspondieron a cirugías mayores complejas lobectomías y segmentectomías anatómicas. En 4 pacientes se agregó un 2° puerto, uno se convirtió a minitoracotomía y uno a toracotomía (5,7% conversión global). La estadía hospitalaria fue en promedio 3,07 ± 3,1 días y el promedio de mantención de pleurostomía de 2,67 ± 1,61 días. Siete pacientes (6,6%) presentaron complicaciones postoperatorias. Un paciente falleció por progresión de su enfermedad, no hubo mortalidad relacionada a la cirugía. Discusión: Las contraindicaciones de la VATS uniportal son las mismas que en la VATS multipuerto. En manos experimentadas, las complicaciones en cirugía por puerto único son bajas. Impresiona tener menos dolor postoperatorio, menor estadía hospitalaria y reintegración precoz a las actividades diarias comparado con la VATS tradicional. Conclusiones: Se presenta la primera serie de VATS uniportal publicada en Chile. Los resultados obtenidos son comparables a los observados en la literatura. Su implementación y desarrollo requiere de una curva de aprendizaje similar a cualquier nueva técnica quirúrgica.


Objective: To describe the initial results with uniportal Video-Thoracoscopic Surgery (VATS) performed in two campuses by members of the Section of Thoracic Surgery of the University of Chile ("Clínica Las Condes" and University of Chile Clinical Hospital). Materials and Method: Between January 2016 and January 2019, a total of 105 patients underwent uniportal VATS. Clinical data was collected retrospectively from digital records including demographic (age, sex) and clinical variables (diagnosis, surgery, duration of the chest tube, length of stay, conversion rate and postoperative complications). Results: Uniportal VATS was performed on 105 patients during the study period. Twenty-eight cases (26.6%) corresponded to lobectomy or anatomic segmentectomy. In 4 cases a 2nd port was required, 1 patient had to be converted to mini-thoracotomy and 1 to thoracotomy (5.8% global conversion). Overall, the median length of stay was 3.07 ± 3.1 days and the median duration of chest tube drainage was 2.67 ± 1.61 days. Seven patients (6.6%) presented complications. One patient died due to progression of his disease, there were no deaths related to the procedures. Discussion: Uniportal VATS has similar indications than multiportal VATS. On experienced hands, uniportal VATS has a low morbidity rate. Uniportal VATS appears to produce less post-operative pain, with shorter hospital stay and a faster return to normal life compared to standard VATS. Conclusion: We present the first uniportal VATS series in Chile. Results were similar to published series. Implementation and development of uniportal VATS requires a learning curve similar to any new surgical procedure.

ABSTRACT

El objetivo de este estudio es la descripción de la novedosa y poco invasiva técnica de marcación de pequeños nódulos pulmonares con lipiodol, guiado con TAC para su posterior resección por cirugía videotoracoscópica con apoyo radioscópico. Se trata de un estudio retrospectivo que incluye 51 pacientes consecutivos en un tiempo comprendido entre junio del 2012 a septiembre del 2017, obteniendo el diagnóstico final mediante la correlación anatomopatológica, representando los procesos malignos el 81% y los benignos el 19%. Mediante esta técnica se lograron identificar y extraer con éxito el 100% de los nódulos marcados, demostrándose la efectividad y seguridad del procedimiento por las mínimas complicaciones relacionadas.


The purpose of this study is describing a novel and minimally invasive technique of CT-guided marking of small pulmonary nodules with lipiodol prior to resection by videothoracoscopic surgery with radioscopic support. This is a retrospective study that includes 51 consecutive patients between June 2012 and September 2017, with the final diagnosis confirmed by pathology. Malignant nodules represented 81% of the cases with the remaining 19% being benign nodules. Through this technique, 100% of the marked nodules were successfully identified and extracted with few procedure related complications and no adverse clinical outcome, demonstrating the effectiveness and safety of the procedure.

ABSTRACT

Background: Pulmonary nodules are common, and surgery is the only alternative that allows a diagnostic and therapeutic management in a single procedure. Aim: To report the epidemiological, radiological, surgical and pathological features of excised pulmonary nodules. Material and Methods: Review of medical records of patients in whom a pulmonary nodule was excised between 2014 and 2018. Those with incomplete data or without a pathological study were excluded from analysis. Results: We retrieved 108 records and 8 had to be excluded, therefore 100 patients aged 34 to 82 years (57% females) were analyzed. Sixty percent had a history of smoking. Mean nodule size was 16 mm and the solid type was the most common (65%). Forty five percent of nodules had irregular margins and 55% were in the superior lobes. All patients operated by video-assisted thoracoscopic surgery and 40% underwent a lobectomy. Malignant lesions were observed in 87% of biopsies and a pulmonary adenocarcinoma was found in pathology in 40%. Conclusions: A multidisciplinary approach of pulmonary nodules, using adapted international guidelines, accomplishes an appropriate management, decreasing unnecessary surgical interventions.

ABSTRACT

Pulmonary fibrosis is a progressive disease. Lung transplantation is the only effective therapy for a group of patients. Objective: To evaluate results of lung transplantation for fibrosis up to a 5 years of follow up. Methodology: Retrospective review of clinical records of patients subjected to lung transplantation from Clínica Las Condes and Instituto Nacional del Tórax. Demographic data, type of transplant, baseline and post-transplant spirometry and 6 min walked distance (6MWT), early and late complications and long-term survival rate were analyzed. Results: From 1999 to 2015, 87patients with pulmonary fibrosis were transplanted, in average they were 56 years old, 56% were male, 89% of patients were subjected to a single lung transplant. 16% of them were in urgency. Baseline and 1-3-5 years for FVC were 49-73-83 and 78% of the reference values and for 6MWT were 280, 485, 531 and 468 meters respectively. Predominant complications < 1 year post-transplant were: acute rejection (30%) and infections (42%). Complications after 1 year of transplantation were chronic graft dysfunction (DCI) 57% and neoplasms (15%). The main causes of mortality > 1 year were DCI (45%) and neoplasms (11%). The estimated 1, 3 and 5 year survival rate were 84, 71 and 58% respectively. Conclusions: Lung transplantation in patients with pulmonary fibrosis improves their quality of life and survival rate. The monopulmonary technique is efficient in the long term. Acute rejection and infection were the most common early complications and chronic graft dysfunction was the prevalent long-term complication.

ABSTRACT

La definición clásica de nódulo pulmonar solitario corresponde a una imagen radiológica de menos de 3cms que puede corresponder a múltiples condiciones tanto benignas como malignas. Sin embargo con la masificación del uso del TAC de tórax se detectan actualmente diferentes tipos de NP pequeños, incluso subcentrimétricos: sólidos, en vidrio esmerilado (VE) y mixtos. Cada uno con diferente ritmo de crecimiento y diferente potencial de malignidad. Los recientes avances en oncología torácica, tanto en procedimientos diagnósticos como terapéuticos, han hecho que la definición clásica sea insuficiente para incorporar todas las variaciones en el comportamiento de los diferentes nódulos pulmonares que se pesquisan actualmente. Aparte del enfrentamiento habitual de nódulos sólidos de mayor tamaño, se ha definido el manejo de nódulos pequeños sólidos y subsólidos. Se ha establecido claramente que las lesiones en VE tienen un mayor riesgo de malignidad, existiendo una buena correlación entre el aspecto radiológico y el grado histológico. Las lesiones mixtas que persisten en el tiempo y las lesiones en VE en que se desarrolla un componente sólido son las de más alto riesgo de representar un Adenocarcinoma invasor. Por tanto, todos los nódulos, incluso más pequeños subcentrimétricos, deben ser evaluados por equipos multidisciplinarios, con experiencia en los diferentes algoritmos de manejo y seguimiento. Determinando qué nódulos biopsiar de manera de poder resecar tumores iniciales potencialmente curables. Los tumores pequeños pueden ser operados con técnicas quirúrgicas mínimamente invasivas, incluso resecciones sublobares, con similares resultados oncológicos, pero con menor riesgo y menor deterioro de la capacidad funcional.


The definition of a solitary pulmonary nodule corresponds to a radiological image of less than 3cms that may correspond to multiple conditions both benign and malignant. However with the extended use of Chest CT a great number of small sub-centrimetric Pulmonary Nodules are detected: solids, ground-glass opacities (GGO) and mixed lesions. Each with different growth rates and malignant potential. Diagnostic and treatment advances in thoracic oncology, made the classic definition insufficient to incorporate all the difference in growth rate and behavior of the different lung nodules currently detected. In addition to the management larger solid nodules, new diagnostic and treatment algorithms for small GGO and mixed nodules have been defined. It has clearly established that GGO lesions have an increases risk of malignancy, with correlation between radiologic imaging and pathology. Mixed lesions that persist or enlarge during follow-up, or GGO lesions that develop a solid component have the higher risk of representing an invasive adenocarcinoma. Therefore, all nodules, even small sub-centrimetric, should be evaluated by multidisciplinary teams, with experience in management and treatment algorithms determining when to resect potentially curable tumors. Small tumors can be resected by minimally invasive surgery, including sub lobar resections, with equivalent oncologic outcomes, lower risks and better preservation of pulmonary function.

ABSTRACT

Background: PET/CT (Positron Emission Tomography/Computed Tomography) is widely used in nodal and metastatic staging of lung cancer patients. Aim: To analyze PET/CT detection of metastatic disease in patients with lung cancer. Material and Methods: We reviewed retrospectively F18Fluorodeoxyglucose PET/CT scans performed between December 2008 and December 2013. We selected 143 patients aged 30 to 92 years (63% males) with confirmed lung cancer referred for staging, with no previous treatment. We reviewed whole body PET/CT and brain magnetic resonance images. SUVmax (Standardized Uptake Value maximum) of primary pulmonary lesion, hilar/mediastinal nodes, and distant metastases were calculated. Results: Histological types encountered were adenocarcinoma in 55%, squamous-cell in 15%, small-cell in 8%, large-cell in 6% and adeno-squamous in 2%. In 22 cases (15%) histology was not available. Nodal involvement was observed in 60% of patients (44% hilar and 48% mediastinal). Skip metastases (mediastinal involvement without hilum involvement) were encountered in 17% of cases, and were significantly more common among high uptake lung tumors (p < 0.01). Best SUVmax cut-off for node involvement was 4.4 for hilum and 4.0 for mediastinum (sensibility: 86.4%, specificity: 99.8%). Sixty six patients (46.2%) showed distant metastases on PET/CT. The most common metastases were osseous in 22%, adrenal in 16%, hepatic in14%, pulmonary in 14% and cerebral in 12%. PET/CT detected a second unexpected synchronic cancer in eight patients (6%). Conclusions: PET/CT is accurate for nodal staging using an uptake index as SUVmax. Distant metastases are common, especially in bone, adrenal glands and liver.

ABSTRACT

Se analiza la utilidad de la minilaparoscopia en el estudio de 18 pacientes de sexo femenino con diagnóstico dudoso de apendicitis aguda, todas seleccionadas según el criterio clínico del equipo tratante. Se usó un laparoscopio de 2 mm de diámetro externo y se establecieron criterios claros para proceder con una apendicectomía y todas fueron hechas por laparotomía. Doce pacientes fueron apendicectomizadas, diez de ellas por diagnóstico laparoscópico de apendicitis aguda o duda respecto al estado del apéndice. De ellas, se confirmó el diagnóstico en cinco. En 8 pacientes se encontró patologías ginecológicas, evitándose una laparotomía en cinco. En una paciente la laparoscopia fue terapéutica, permitiendo coagular un folículo ovárico roto activamente sangrante. No hubo morbilidad no mortalidad en esta serie. La minilaparoscopia parece ser un método eficaz y seguro en el estudio de pacientes con diagnóstico dudoso de apendicitis aguda
