PURPOSE: The conventional approach to the diagnosis of mediastinal masses is associated with a high level of inaccuracy and the need for multiple interventions. Robotics has the potential of providing a highly accurate approach to the diagnosis and management of mediastinal masses.
METHODS: From 9/05 - to 9/09, 48 patients were diagnosed with a mediastinal mass and underwent transthoracic robotic biopsy and, if appropriate, robotic resection.
RESULTS: There were 18 anterior, 22, and 8 posterior mediastinal masses. Of the anterior med masses, 15 were thymic in origin, 2 lymphomas, and 1 germ cell. Mid med masses: 12 lymphatic in origin, 10 aerodigestive cysts. Of the post med, 3 neurogenic, 5 benign cysts. The robotic approach was from the right pleural space in 33 patients and from the left pleural space in 15 patients. The sensitivity of the robotic technique was 98% and specificity was 100%. 34 patients underwent simultaneous robotic resection of the mass. Two patients required conversion to an open procedure.
CONCLUSION: Robotic approach to the diagnosis and treatment of mediastinal masses is associated with high sensitivity and specificity for diagnosis.
CLINICAL IMPLICATIONS: In patients in whom resection of a mediastinal mass is indicated, the robot can be used for resection in the same operative setting.
