Cadaver specimens underwent pre\u2010 and postoperative thoracic computed tomographic scans. Seven dogs were placed in dorsal recumbency and mediastinoscopy was performed via a SILS port placed cranial to the thoracic inlet with CO<jats:sub>2<\/jats:sub> insufflation of the mediastinum at 2\u20134\u2009mmHg. Retrieval of all CT and visually identified mediastinal lymph nodes (LN) was attempted; endoscopic compartmental and individual LN dissection times and subjective operative challenges were recorded. Procedural success scores for visualization and dissection as well as NASA\u2010task force index scores were recorded per lymph node, per cadaver.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Median time required for initial approach including SILS placement was 5\u2009min (range 5\u201310\u2009min). Individual LN retrieval times ranged from 2 to 32\u2009min. Mediastinoscopic retrieval of LNs was most commonly successful for the left tracheobronchial LN (7\/7), followed by the right tracheobronchial LN (4\/7), the left and right sternal LNs (3\/7 each), and the cranial mediastinal LNs (1\/7).
