OBJETIVO: Evaluar resultados y sobrevida de pacientes pediátricos trasplantados de pulmón. MÉTODOS: Análisis retrospectivo de registros clínicos de pacientes TP ≤ 15 años de Clínica Las Condes. Se analizaron datos demográficos, tipo de trasplante, función pulmonar basal y post trasplante, complicaciones precoces y tardías y sobrevida. RESULTADOS: Nueve pacientes < 15 años de edad se han trasplantado. La edad promedio fue 12,7 años. La principal indicación fue fibrosis quística (7 pacientes). El IMC promedio fue de 17,6 y todos estaban con oxígeno domiciliario. El 77% utilizó soporte extracorpóreo intraoperatorio. Las principales complicaciones precoces fueron hemorragia y la disfunción primaria de injerto mientras que las tardías fueron principalmente las infecciones y la disfunción crónica de injerto. Cuatro pacientes han fallecido y la sobrevida a dos años fue de 85%. El trasplante les permitió una reinserción escolar y 3 lograron completar estudios universitarios. CONCLUSIÓN: El trasplante pulmonar es una alternativa para niños con enfermedades pulmonares avanzadas mejorando su sobrevida y calidad de vida.
Lung transplantation (TP) is a treatment option in children with terminal lung diseases. OBJECTIVE: To evaluate the results and survival of pediatrics lung transplant patients. METHODS: Retrospective analysis of clinical records of lung transplantation of patients ≤ 15 years from Clínica Las Condes, Santiago, Chile. Demographic data, type of transplant, baseline and post transplant lung function, early and late complications and survival rate were analyzed. RESULTS: Nine patients ≤ 15 years-old were transplanted. The average age at transplant was 12.7 years. The main indication was cystic fibrosis (7 patients). The average BMI was 17.6 and all the patients were with home oxygen therapy. 77% used extracorporeal intraoperative support. Average baseline FEV1 was 25.2% with progressive improvement in FEV1 of 77% in the first year. The main early complications were hemorrhage and primary graft dysfunction, while late complications were infections and chronic graft dysfunction. Four patients have died and the estimated 2 years survival was 85%. They achieved school reinsertion and three managed to complete university studies. CONCLUSION: Lung transplantation is an alternative for children with advanced lung diseases improving their survival and quality of life.

Background: The number of patients waiting for a lung transplant worldwide greatly exceeds the number of available donors. Ex vivo lung perfusion is a useful tool that allows marginal donor lungs to be evaluated and reconditioned for a successful lung transplantation. Aim: To describe the first Chilean and Latin American experience in ex vivo lung perfusion for marginal donor lungs before transplantation. Material and Methods: Descriptive analysis of all ex vivo lung perfusion conducted for marginal donor lungs at a private clinic, from April 2019 to October 2020. High risk donor lungs and rejected lungs from other transplantation centers were included. The "Toronto Protocol" was used for ex vivo lung perfusion. Donor lung characteristics and recipient outcomes were studied. Results: During the study period, five ex vivo lung perfusions were performed. All lungs were reconditioned and transplanted. No complications were associated. There were no primary graft dysfunctions and only one chronic allograft dysfunction. There was no mortality during the first year. The median arterial oxygen partial pressure/fractional inspired oxygen ratio increased from 266 mm Hg in the donor lung to 419 after 3 hours of ex vivo lung perfusion (p = 0.043). Conclusions: ex vivo lung perfusion is a safe and useful tool that allows marginal donor lungs to be reconditioned and successfully transplanted.

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.

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.

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.

Objectives: To describe and evaluate factors associated with morbidity and mortality in surgically treated parapneumonic empyemas (PNE). Method: Retrospective review between January 2000 and August 2006. We described clinical features and we performed univariate and multivariate analysis to find the factors associated with morbidity and mortality. SPSS 15.0 program was used in the statistical analysis. Results: 242 of 343 surgically treated empyemas (70.6 percent) were paraneumonic. Of these 165 (68.2 percent were men, average age 52.1 years, 229 (94.6 percent were community-acquired pneumonia (CAP) and 13 (5.4 percent) nosocomial. Germs were isolated in pleural fluid in 57 (23.6 percent). Surgical procedures were: 183 (75.6 percent decortications, 49 (20.2 percent pleurotomies, 7 (2.9 percent video-assisted surgery and 3 (1.2 percent decortications with pulmonary resection. Complications occurred in 65 cases (26.9 percent) and 16 patients died (6.6 percent). We found variables associated with morbidity and mortality. Conclusions: PNE is the most common cause of empyema, mostly associated with CAP and germs are difficult to identify. Decortication is the most common surgical treatment. Morbidity and mortality are present. Variables associated with morbidity and mortality were identified in this clinical series.

Introduction: In the past two decades the advances in minimally invasive surgery have revolutionized surgical practices in all subspecialties. In pulmonary resections lobectomy by assisted video-thoracoscopy (VATS) has demonstrated to have less perioperative complications, less inflammatory response and similar oncological results in comparison with lobectomy by thoracotomy. Methods and Patients: We present a retrospective study of 30 patients subjected to lobectomy by VATS. Diagnoses, complications intra and post-surgery, bleeding, conversion to thoracotomy, operatory time, lymphoadenectomy, pleurostomy and hospitalization time, were the variables analyzed. Results: 90 percent of the 30 patients (n = 27) had an oncological diagnosis, the remainder patients had benign lesions (n = 3), all of them presented bronchiectasis. TNM staging showed equal distribution for stages I and II. We obtained on average 13 nodes by lymphoadenoectomy (range: 9 to 18 nodes). Operatory time was 124 min on average. With respect to complications 50 percent of them (n = 3) bleed more than 1,000 mL. The conversion rate in our series was 16.5 percent (n = 5). Pleurostomy lasted 4.09 days on average (range: 2 to 9 days). There was no mortality in our series. Conclusion: In our series, lobectomy by VATS had equal range of intra and post- surgery complications as compared to toracotomy. We believe that our study demonstrates a benefit in the recovery time of our patients.
Introducción: En las últimas dos décadas los avances en cirugía mínimamente invasiva han revolucionado la práctica quirúrgica en todas las subespecialidades. En resecciones pulmonares la lobectomía por videotoracoscopía (VATS), en comparación con resecciones por toracotomía, ha demostrado, además del menor número de complicaciones perioperatorias, una menor respuesta inflamatoria y equivalencia en resultados oncológicos. Pacientes y Métodos: Se presenta una serie retrospectiva de 30 pacientes en quienes se realizó una lobectomía por VATS. Se analizan los resultados con respecto a complicaciones quirúrgicas y postquirúrgicas y considerando variables de diagnóstico, linfadenectomía, sangrado quirúrgico, conversión a toracotomía, tiempo operatorio, días de estadía y días con pleurostomía. Resultados: Las indicaciones quirúrgicas de nuestra serie fueron en un 90 por ciento (n = 27) por patología neoplásica, el 10 por ciento restante (n = 3) correspondió a patología benigna (bronquiectasias). La etapificación TNM dentro del subgrupo de cáncer pulmonar se distribuyó homogéneamente entre las etapas I y II. La linfadenectomía obtuvo un promedio de 13 ganglios con un rango entre 9 y 18. El tiempo quirúrgico promedio fue de 124 minutos. De las complicaciones, un 50 por ciento de estas (n = 3) se debieron a sangrado de más de 1.000 mL. La tasa de conversión en nuestra serie es de 16,6 por ciento (5 casos). El promedio de días con drenaje fue de 4,09 días con rango entre 2 y 9 días. No hubo mortalidad a 60 días. Conclusión: En la serie presentada se evidencia que la lobectomía por VATS es equivalente a la toracotomía con respecto al número de complicaciones. Creemos como equipo que presenta beneficios en el tiempo de recuperación del paciente.

Background: Pleural empyema still has a dismal prognosis. Aim: To describe features and prognostic factors of patients with pleural empyema subjected to surgical procedures. Material and Methods: Retrospective review of 343 patients with pleural empyema (mean age 52 years, 71 percent males), that were subjected to any type of surgical procedure. Criteria for diagnosis of empyema were a positive culture, a fluid pH of less than 7.2 or a compatible macroscopic appearance of the fluid. Results: Empyema was secondary to pneumonia in 243 patients (71 percent, secondary to surgical procedures in 41 patients (12 percent), secondary to trauma in 19 patients (5.5 percent), secondary to a lung abscess in 10 patients (3 percent), tuberculous in 10 patients (3 percent), neoplastic in two cases (0.6 percent), secondary to pneumothorax in 2 cases (0.6 percent) and of unknown origin in 13 patients (4 percent). A microorganism was isolated from pleural fluid in 89 patients (26 percent). The surgical procedures performed were 251 decortications by thoracotomy (73 percent), 70 pleurotomies (20 percent), 11 video assisted surgeries (3 percent), seven decortications with lung resections and four fenestrations. Complications were recorded in 104 patients (30 percent), 29 patients were re-operated (8.5 percent) and 31 died (10 percent), all due to sepsis. Conclusions: The main cause of pleural empyema is pneumonia. In most patients, microorganisms are not isolated from pleural fluid, thoracotomy with decortication is the most frequent surgical procedure. There is a high rate of complications and mortality.

Se realizaron: 251 (73,2 por ciento) decorticaciones por toracotomía, 70 (20,4 por ciento) pleurotomías, 11 (3,2 por ciento) cirugías video-asistidas, 7 (2,1 por ciento) decorticaciones con resección pulmonar y 4 (1,2 por ciento) fenestraciones. Presentaron complicaciones 104 (30,3 por ciento) pacientes. Se reoperaron 29 (8,5 por ciento). Fallecieron 31 (9,6 por ciento), todos por sepsis. Se encontraron variables asociadas a morbi-mortalidad. Conclusiones: El EP tiene como causa más frecuente el empiema paraneumónico seguido de los postoperatorios, en la mayoría no se identifican gérmenes en líquido pleural. La toracotomía con decorticación es el procedimiento quirúrgico más frecuente. El EP tiene una considerable morbi-mortalidad. Se identifican variables asociadas a morbilidad y mortalidad.

El traumatismo de tórax es una situación altamente desafiante en el manejo de urgencia. Requiere conocimientos de las complicaciones que pueden poner en riesgo vital al paciente en pocos minutos como de un adecuado manejo primario de las complicaciones que se pueden presentar en el mediano y largo plazo. De la mortalidad total del trauma, un 75 por ciento se debe a trauma torácico como causa primaria o como elemento contribuyente. Es por esto que el manejo de estas lesiones torácicas es esencial en el trabajo de urgencia. Un 80 por ciento de las lesiones torácicas pueden manejarse con maniobras no quirúrgicas, pero el 15 por ciento a 20 por ciento restante requerirá manejo quirúrgico, que es altamente desafiante, por lo complejas que pueden llegar a ser las lesiones de estructuras vitales presentes en el tórax. En la siguiente revisión mostramos el manejo de las lesiones más frecuentes en traumatismo torácico y las distintas indicaciones de toracotomías que se pueden presentar en los servicios de urgencia.
Thoracic trauma is an extremely challenging situation in the emergency room. Both ER physicians and surgeons should have knowledge of how to manage immediate life threatening injuries and the related complications that can present later. The primary cause or contributing element of seventy five percent of trauma related mortality is thoracic injury. Eighty percent of thoracic injuries can be managed non-surgically. The remaining 15 percent to 20 per cent will require challenging surgical procedures, due to the involvement of vital organs and vessels. In this review, we present the management of the most common trauma related thoracic injuries that can present in the ER and the different indications for thoracotomy.

Mediastinal tumors have multiple presentation forms and various pathological origins. Sometimes they reach a large size and can involve the system of superior vena cava by compression or infiltration. We present a 48 year old man admited for dyspnea, headache and palpitations in decubitus, for the last two months. The X-ray and chest computed tomography showed an anterior mediastinal tumor and the tru-cut pathological study concluded leiomyosarcoma. He underwent surgical treatment; the tumor compromised the system of the superior vena cava and was resected with ligation and resection the left brachiocephalic trunk. Part of the superior vena cava was reconstructed with autologous pericardium. The right phrenic nerve was surrounded by the tumor mass and was resected in block. The patient recovered satisfactorily and was discharged on the eleventh day post surgery. The histopathologic study of the surgical specimen confirmed a leiomyosarcoma G2 (3,100 gr). Full adjuvant radiotherapy was done. At 15 months after surgery the patient is in good condition without evidence of recurrence or superior vena cava syndrome.
Los tumores del mediastino pueden tener múltiples formas de presentación y diversos orígenes anato-mopatológicos. A veces alcanzan gran tamaño y pueden comprometer por compresión o infiltración el sistema de la vena cava superior. Presentamos el caso de un hombre de 48 años que consultó por disnea, cefalea y palpitaciones en decúbito de dos meses de evolución. En la radiografía y en la tomografía computada de tórax se demostró un tumor de mediastino anterior, el estudio anatomopatológico mediante biopsia trucut concluyó leiomiosarcoma. Se realizó tratamiento quirúrgico, se resecó la masa tumoral que comprometía el sistema de la vena cava superior, se ligó y resecó el tronco venoso braquiocefálico izquierdo o innominado y se reconstruyó parte de la vena cava superior con parche de pericardio autólogo. El nervio frénico derecho se encontraba rodeado por la masa tumoral y se resecó junto con el tumor. El paciente evolucionó satisfactoriamente y fue dado de alta al décimo primer día post operado. El estudio de anatomía patológica de la pieza operatoria confirmó un leiomiosarcoma G2 de 3.100 gramos. Se completó tratamiento con radioterapia post operatoria. A 15 meses post operado el paciente se encuentra en buenas condiciones generales, sin evidencias de recidiva y sin síndrome de vena cava superior.

Hereditary hemorrhagic telangiectasia (Osler-Weber-Rendu syndrome) is an autosomal dominant vascular disease that can be associated with pulmonary arteriovenous fistulas. We report a 16 years old female with an Osler-Weber-Rendu syndrome and a history of frequent episodes of epistaxis since the age of 10 years. A Chest CAT sean performed on that occasion showed an arteriovenous fistula. The patient presented with progressive dyspnea, low arterial oxygen saturation and clubbing of fingers. An echocardiogram and lung perfusion scintigram confirmed the presence a right to left shunt. The patient was subjected to a lobectomy with a good postoperative evolution.
Las Fístulas Arteriovenosas Pulmonares (FAVP son malformaciones vasculares infrecuentes. La Telangectasia Hemorrágica Hereditaria o Enfermedad de Rendu-Osler-Weber (EROW) es una enfermedad hereditaria autosómica dominante que se asocia con frecuencia a dichas malformaciones vasculares pulmonares. Presentamos el caso de una mujer de 16 años con EROW y una FAVP única, sintomática y que comprometía extensamente el lóbulo medio, en quien realizamos tratamiento con cirugía resectiva pulmonar (lobectomía media) y que evolucionó satisfactoriamente con desaparición de la sintomatología.
