ABSTRACT

OBJECTIVES: To report our experience in the surgical treatment of patients having acquired and congenital tracheal stenosis. MATERIAL AND METHODS: Fifty eight patients with tracheal stenosis were surgically treated between July 2005 and May 2016, 29 were females and 29 were males. Thirty patients had acquired stenosis and 28 had congenital stenosis. RESULTS: Five to 12 rings were resected (median 5) in 26 patients, in 2 cartilage was grafted in the anterior wall, in another carinostomy was performed, and in the remaining, the trachea was replaced using an aortic cryopreserved graft. In those with congenital stenosis, 14 patients underwent slide technique; in eleven, 3 to 6 rings were resected (median 5); in 3 a patch was grafted in the anterior tracheal wall. Seven patients died: 2 with acquired stenosis and 5 with congenital stenosis. Global survival was 88% (28 of 30 patients with acquired stenosis and 23 of 28 with congenital). From 28 living patients operated on due to acquired stenosis, 26 are asymptomatic, one presents graft stenosis, and one has a stoma in the aortic graft. From 23 living patients operated on due to congenital stenosis, 20 remain asymptomatic and 3 have tracheal stents placed on. CONCLUSIONS: Surgical treatment of acquired stenosis is easier and presents less severe complications. Congenital stenosis often requires more than one procedure to control the disease, and presents a higher mortality rate.


OBJETIVOS: Describir nuestra experiencia en el tratamiento quirúrgico de pacientes con estenosis traqueal adquirida y congénita. MATERIAL Y METODOS: Cincuenta y ocho pacientes con estenosis de tráquea fueron intervenidos quirúrgicamente entre julio de 2005 y mayo de 2016, 29 eran de sexo femenino y 29 de sexo masculino. Treinta pacientes tenían una estenosis de origen adquirido y 28 de origen congénito. RESULTADOS: Fueron resecados entre 5 y 12 anillos (mediana 5) en 26 pacientes con estenosis adquirida, en 2 se efectuó injerto de cartílago en cara anterior, en 1 carinostomía, y en el restante (a este paciente se le había realizado previamente una resección laringotraqueal) se efectuó un reemplazo traqueal con aorta criopreservada. De los veintiocho pacientes con estenosis congénita, en 14 se empleó la técnica de deslizamiento, en 11 se resecaron entre 3 y 6 anillos (mediana 5), y en 3 se colocó un injerto en cara anterior de la tráquea. Fallecieron 7 pacientes: 2 con estenosis adquirida y 5 con estenosis congénita. La supervivencia global fue del 88% (28 de 30 pacientes con estenosis adquirida y 23 de 28 con congénita). De los 28 pacientes vivos operados por estenosis adquirida, 26 se encuentran asintomáticos, uno presenta estenosis del injerto y otro tiene un estoma en el injerto de aorta. De los 23 pacientes vivos operados por estenosis congénita, 20 se encuentran asintomáticos y 3 tienen endoprótesis colocadas. CONCLUSIONES: En nuestra experiencia, la resolución quirúrgica de la estenosis traqueal adquirida resultó más sencilla y presentó menos complicaciones. Los pacientes con estenosis traqueal congénita necesitaron generalmente más de un procedimiento para el control de su sintomatología, y presentaron mayor mortalidad.

ABSTRACT

INTRODUCTION: Primary lung tumors in children are rare, being the myofibroblastic lung tumor (MLT) reported as the most common. Nevertheless the literature about it is scarce, and mostly consistent of case reports. The aim of this article is to describe the results obtained in a group of patients with this tumor treated in a tertiary pediatric hospital. METHODS: A single institution retrospective chart review was performed with institutional review board approval. All patients treated between 1990 and 2010 with diagnosis of MLT were included. Age, symptoms at presentation, surgical procedures, complications, histopathology and follow-up were reviewed. RESULTS: 9 patients were identified. The commonest symptoms at presentation were fever and cough (n=6), and seizures (n=2). Surgical treatment consisted in complete resection in 8 patients and partial resection in 1. To achieve this 3 patients underwent pneumonectomy and 6 lobectomy. Two of the patients with pneumonectomy required also a partial resection of the right atrium and both had cerebral lesions. The mean follow-up was 2.8 years (r:0.16-12) and all the patients that remained in follow-up (66%) are alive at the moment. DISCUSSION: Complete surgical resection in MLT is possible, however, to achieve this complex procedures and a multidisciplinary approach might be needed. Although the potential of distant metastasis is not clearly reported, we think that it is a topic that must be carefully revised.

ABSTRACT

Introducción. El tumor miofibroblástico (TMF) está descrito como el tumor primario de pulmón más frecuente en pediatría. Sin embargo, la literatura al respecto es escasa y en su mayoría consiste en reportes de casos. Nuestro objetivo es describir los resultados obtenidos en un grupo de pacientes con este tipo de tumor tratados en un hospital pediátrico de derivación en 20 años. Material y métodos. Se realizó una revisión retrospectiva de las historias clínicas de niños tratados entre 1990 y 2010 con diagnóstico de TMF de pulmón. Se registraron edad, síntomas al momento del diagnóstico, tratamiento quirúrgico, complicaciones peri y postoperatorias, análisis histopatológico y evolución clínica. Resultados. Fueron intervenidos en nuestra institución 9 pacientes con diagnóstico de TMF con una relación varón/mujer de 1,25:1. Las presentaciones más frecuentes fueron tos y fiebre (n=6) y convulsiones(n=2). El tratamiento realizado consistió en la resección quirúrgica completa en 8 e incompleta en 1. Para lograrlo se realizaron 3 neumonectomías y 6 lobectomías. Dos de los pacientes neumonectomizados requirieron resección parcial de aurícula izquierda y ambos pacientes presentaron metástasis cerebrales. El seguimiento promedio fue de 2,8años (r:0,16-12) y todos los pacientes que continúan en control (66%)se encuentran vivos en el momento del estudio. Discusión. La resección quirúrgica completa de los TMF de pulmónes posible, si bien puede requerir cirugías complejas y un abordaje multidisciplinario. Si bien la diseminación a distancia no está claramente descrita, creemos que es un tema que debe ser cuidadosamente revisado (AU)
