Mediastinoscopy: Test Overview
Content provided by Healthwise
Test Overview
Mediastinoscopy is a surgical procedure to examine the inside of the upper chest between and in front of the lungs (mediastinum).
During a mediastinoscopy, a small incision is made in the neck just above the breastbone or on the left side of the chest next to the breastbone. Then a thin scope (mediastinoscope) is inserted through the opening. A tissue sample (biopsy) can be collected through the mediastinoscope and then examined under a microscope for lung problems, such as infection, inflammation, or cancer. See an illustration of mediastinoscopy 
.
In many cases mediastinoscopy has been replaced by other biopsy methods that use computed tomography (CT), echocardiography, or bronchoscopy to guide a biopsy needle to the abnormal tissue. Mediastinoscopy may still be needed when these methods cannot be used or when they do not provide conclusive results.
