First Rib Resection for Thoracic Outlet Syndrome: The Robotic Approach.

Abstract

First rib resection is a well-recognized treatment option for thoracic outlet syndrome (TOS). In case of a vascular insufficiency that can be provoked and/or progressive neurologic symptoms without response to conservative treatment, surgical decompression of the space between the clavicle and the first rib is indicated. The aim of this paper is to present our experience with a new minimally invasive robotic approach using the da Vinci Surgical System®. Between January 2015 and October 2017, eight consecutive first rib resections in seven patients were performed at our institution. Four patients presented with neurologic (one bilateral), and three patients with vascular (venous) impairment. In all cases, a transthoracic robotic-assisted approach was used. The first rib was removed using a 3-port robotic approach with an additional 2-cm axillary incision in the first six patients. The latest resection was performed through only three thoracic ports. Median operative time was 108min, and the median hospital stay was 2days. Postoperative courses were uneventful in all patients. Clinical follow-up examinations showed relief of symptoms in all nonspecific TOS patients, and duplex ultrasonography confirmed complete vein patency in the remaining patients 3months after surgery. While there are limitations in conventional transaxillary, subclavicular and supraclavicular approaches in the first rib resection, the robotic method is not only less invasive but also allows better exposure and visualization of the first rib. Furthermore, the technique takes advantage of the benefits of the da Vinci Surgical System® in terms of 3D visualization and improved instrument maneuverability. Our early experience clearly demonstrates these advantages, which are also supported by the very good outcomes.
