Robotic subxiphoid-optical thymectomy.

Area of Science:

• Thoracic Surgery
• Robotic Surgery
• Minimally Invasive Procedures

Background:

• Median sternotomy is a standard approach for thymectomy but involves significant invasiveness.
• Subxiphoid approaches have been explored for thymectomy to reduce invasiveness.
• Optimizing visualization and instrument maneuverability in minimally invasive thymectomy remains a challenge.

Purpose of the Study:

• To evaluate the efficacy and safety of a novel robotic-assisted thymectomy technique using a subxiphoid optical approach.
• To assess the advantages of this technique for dissecting critical anatomical structures during extended thymectomy.

Main Methods:

• A robotic-assisted thymectomy was performed using a subxiphoid port primarily for the robotic scope.
• The technique was designed to prevent instrument collision and facilitate dissection.
• Focus was placed on the dissection of bilateral phrenic nerves and the left brachiocephalic vein.

Main Results:

• The subxiphoid optical approach provided a surgical view comparable to median sternotomy.
• The technique allowed for safe and accurate dissection of the bilateral phrenic nerves.
• Precise dissection of the left brachiocephalic vein was achieved, crucial for extended thymectomy.

Conclusions:

• Robotic-assisted thymectomy via a subxiphoid optical approach is a viable and effective alternative to sternotomy.
• This method offers enhanced safety and precision for critical structure dissection, especially in complex cases like myasthenia gravis.
• The technique facilitates extended thymectomy by improving visualization and instrument access.
