Abstract

Endoscopic and endobronchial ultrasound are complementary techniques. When combined, they allow for nearly complete mediastinal staging in lung cancer. Each technique has inherent strengths and weaknesses, but when used simultaneously they become far more powerful, to the extent that mediastinoscopy–a more expensive and invasive procedure-is expected to decline in use as the application of endoscopic and endobronchial ultrasound becomes more widespread. The incorporation of these ultrasound techniques has been shown to lead to fewer thoracotomies, benefiting patients and also society, given that costs are thereby reduced. We reflect on recent developments in the field, discuss current debates, and propose a view of what the future holds in store.

Resumen

La utrasonografía endoscópica y la endobronquial son métodos complementarios. Combinadas, permiten una estadificación mediastínica casi completa del cáncer de pulmón sin cirugía. Son más potentes cuando se utilizan simultáneamente, ya que cada una de ellas tiene puntos fuertes y puntos débiles. Es de esperar que con la utilización de ambas se reduzca el uso de la mediastinoscopia (un proceso más caro e invasivo). Se ha demostrado que el empleo de ambas técnicas conduce a la realización de menos toracotomías, lo que beneficia no sólo a los pacientes, sino también a la sociedad, ya que se ahorran costes. En el artículo se realiza también una reflexión sobre los avances más recientes en este ámbito, se examinan los debates actuales al respecto y se presenta una perspectiva para el futuro.
