Robotic resection of the "offending portion" of the first rib in patients with thoracic outlet syndrome (TOS) has been associated with excellent results. The results have been due to (I) a better understanding of the pathogenesis of TOS, and (II) the technical advantages of the robotic platform.This article outlines the recent understanding of the pathogenesis of TOS, and reports the experience with robotic resection of the "offending portion" of the first rib in patients with neurogenic and venous TOS. Patients diagnosed with TOS underwent robotic first rib resection. Diagnosis of TOS was made by magnetic resonance angiography (MRA). On a thoracoscopic platform, the robot was used to dissect the "offending portion" of the first rib. A total of 162 patients underwent robotic first rib resection. Eighty-three patients underwent robotic first rib resection for Paget-Schroetter syndrome (PSS) (venous TOS). There were 49 men and 34 women. Mean age was 24±8.5 years. Operative time was 127.6±20.8 minutes. Median hospitalization was 4 days. There were no surgical complications, neurovascular injuries, or mortality. At a median follow-up of 24 months, all patients had an open subclavian vein (SV) for a patency rate of 100%.Seventy-nine patients underwent robotic first rib resection for neurologic symptoms of the upper extremity (neurogenic TOS). There were 29 men and 50 women. Mean age was 34±9.5 years. Operative time was 87.6±10.8 minutes. There were no intraoperative complications. Hospital stay ranged from 2-4 days with a median hospitalization of 3 days. There were no neurovascular complications. There was no mortality. In patients with neurogenic symptoms, Quick DASH Scores (mean ± SEM) decreased from 60.3±2.1 preoperatively to 5±2.3 in the immediate postoperative period, and 3.5±1.1 at 6 months (P<0.0001). Immediate relief of symptoms was seen in 71/79 (91%) patients. Persistent paresthesia was seen in 9/79 (9%) immediately postop and 3/79 (3.8%) patients at 6 months. Following the appropriate identification of the "offending portion" of the first rib which results in compression of the SV at its junction with the innominate vein by MRA, robotic resection of the "offending portion" of the first rib allows is associated with excellent results.
Conventionally, resection of the first rib has been performed by the transaxillary and supraclavicular approaches. These approaches are hampered by poor visualization and exposure of the operative field, neurovascular complications, and less than optimal surgical outcomes. The Robotic Surgical System allows for high-definition, magnified, three-dimensional visualization of the operative field and is associated with accurate instrument maneuverability in a confined space. Importantly, the robotic transthoracic technique facilitates the disarticulation of the costo-sternal joint, which appears to be the most critical determinant of surgical success. Robotic first rib resection has been associated with the best-reported outcomes in patients with both Neurogenic and Venous (Paget Schroetter Syndrome) Thoracic Outlet Syndrome (TOS). This paper outlines the technique of robotic first rib resection with disarticulation of the costo-sternal joint for patients with TOS.
