Which procedure is described as an anterior mediastinotomy to reach lymph nodes not accessible by EBUS or mediastinoscopy?

• A. Chamberlain procedure
• B. Mediastinoscopy
• C. Pleural biopsy
• D. VATS

Answer: (A)

An anterior mediastinotomy to reach nodes not accessible by EBUS or mediastinoscopy is performed with the Chamberlain procedure, also known as parasternal mediastinotomy. This approach uses a left thoracic entry to create a window in the anterior mediastinum, allowing biopsy of ipsilateral left paratracheal and aortopulmonary window lymph nodes that lie inaccessible to the neck-based mediastinoscopy or to endobronchial ultrasound sampling. It’s chosen specifically when imaging suggests involvement in those anterior-mediastinal nodal stations and those nodes would be missed by less invasive approaches. Mediastinoscopy targets the superior mediastinum from a neck incision, pleural biopsy samples the pleura, and VATS is a thoracoscopic approach that can access various thoracic structures but is not the classic anterior mediastinotomy used to reach those specific nodes.
