A mediastinoscope is a thin, tube-like instrument with a light and a lens for viewing. It may also have a cutting tool. Tissue samples may be taken from lymph nodes on the right side of the chest and checked under a microscope for signs of cancer. In an anterior mediastinotomy (Chamberlain procedure), the incision is made beside the breastbone to remove tissue samples from the lymph nodes on the left side of the chest. Mediastinoscopía.

Un mediastinoscopio es un instrumento en forma de tubo delgado con una luz y una lente, que se utiliza para observar. También puede tener un instrumento para cortar. Se pueden tomar muestras de tejido de los ganglios linfáticos que se encuentran a la derecha del pecho para analizarlas al microscopio y determinar si hay algún signo de cáncer. En una mediastinoscopía anterior (Procedimiento de Chamberlain), la incisión se hace al lado del esternón para extraer muestras de tejido de los ganglios linfáticos que se encuentran al lado izquierdo del pecho.
