A Prospective, Single-Center Investigation of the da Vinci SP® Surgical System in Anterior Mediastinal Disease

Myasthenia Gravis Clinical Trial

Official title: A Prospective, Single-Center Investigation of the da Vinci SP® Surgical System in Anterior Mediastinal Disease

Status Active, not recruiting

Clinical Trial Summary

Endpoints (Outcome measures)：

1. Primary endpoint: Incidence of conversion rate during surgery

• The primary performance endpoint will be assessed as the ability to successfully complete the planned mediastinal procedure with da Vinci SP System, with no conversion to open surgery, video-assisted thoracoscopic surgery (VATS), multi-port robotic surgery or approach requiring undocking of the da Vinci SP Surgical System in order to complete the planned procedure using the alternate approach. Use of additional assistant port(s) is not considered a conversion

2. Secondary endpoints: Incidence of treatment related adverse events - The safety endpoint will be assessed as the incidence of all intra-operative and post-operative adverse events that occur through the 30-day follow up period

Clinical Trial Description

During the past several years, minimally invasive thoracic surgery has evolved from thoracoscopic approaches using 3 -4 ports to a single incision video-assisted thoracoscopic surgery (VATS) techniques. Recently, the experience acquired with the uniportal VATS technique through the intercostal space has allowed the development of a uniportal VATS subxiphoid or subcostal approach for anterior mediastinal tumor resections. The advantage of using a subxiphoid or subcostal entry is to reduce pain by avoiding possible trauma of intercostal nerves caused by thoracic incisions. However, the longer distance from the subxiphoid or subcostal incision to the anterior mediastinal area makes this approach more difficult to perform extended thymothymectomy. During this same period of evolution into uniportal VATS surgery, robotic thoracic surgery has gained popularity as an alternative to traditional VATS. The advantages of robotics are the ability to perform surgery more precisely with articulated or wristed instruments, motion scaling, and tremor filtration, as well as improved visualization thanks to 3D high-definition video. However, currently 4 -5 incisions are still necessary to perform anatomic robotic resections.Recently, there has been a convergence of these two trends-uniportal surgery and robotic-assisted surgery-and has resulted in a single port robotic system, the da Vinci SP by Intuitive Surgical Cooperation. For this new platform, investigators plan to practice in extended thymothymectomy ;
