ABSTRACT
INTRODUCCIÓN: Para facilitar la localización intraoperatoria de los nódulos pulmonares existe la alternativa de marcarlos previamente con lipiodol. OBJETIVO: Describir los resultados quirúrgicos de los pacientes sometidos a resección por videotoracoscopía de nódulos pulmonares marcados previamente con lipiodol. MATERIAL Y MÉTODOS: Estudio descriptivo. Se incluyeron los pacientes que fueron sometidos a resección por videotoracoscopía de nódulos pulmonares marcados con lipiodol, en Clínica Las Condes e Instituto Nacional del Tórax, entre junio de 2012 y junio de 2019. Se consideraron variables demográficas, radiológicas, quirúrgicas e histológicas. RESULTADOS: Se estudió un total de 93 pacientes. La edad promedio fue 63,5 (± 11,9) años. El tamaño promedio de los nódulos fue de 10,7 (± 5,8) mm. Se identificó y extrajo el 100% de los nódulos marcados. Los días de hospitalización promedio fueron 4,7 (± 6,9). Solo se registró un fallecimiento de causa no quirúrgica. CONCLUSIONES: La resección videotoracoscópica de nódulos pulmonares marcados previamente con lipiodol, es una técnica segura y eficaz.
BACKGROUND: To facilitate the intraoperative location of lung nodules there is the alternative of pre-marking them with lipiodol. OBJECTIVE: To describe the surgical results of patients undergoing videotoracoscopy resection of pulmonary nodules previously marked with lipiodol. MATERIAL AND METHODS: Descriptive study. Patients who underwent videotorcoscopy resection of pulmonary nodules marked with lipiodol were included at Clínica Las Condes and Instituto Nacional del Tórax between June 2012 and June 2019. Demographic, radiological, surgical and histological variables were considered. RESULTS: A total of 93 patients were studied. The average age was 63,5 (± 11.9) years. The average size of the nodules was 10.7 (± 5.8) mm. 100% of the marked nodules were identified and extracted. The average hospitalization days were 4.7 (± 6.9). Only one death of non-surgical cause was recorded. CONCLUSIONS: Videotoracoscopic resection of pulmonary nodules previously marked with lipiodol is a safe and effective technique.

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.
