[Thymectomy].

Area of Science:

• Surgical Oncology
• Neurology
• Thoracic Surgery

Background:

• Extended thymectomy, established by Masaoka in 1981, is a cornerstone surgical treatment for myasthenia gravis.
• Thoracoscopic thymectomy presents a less invasive alternative to conventional median sternotomy for anterior mediastinal lesions.
• Techniques like CO2 insufflation and rib hook retraction enhance surgical visualization and working space in thoracoscopic procedures.

Purpose of the Study:

• To review the evolution and techniques of thymectomy for myasthenia gravis.
• To highlight the benefits and advancements in thoracoscopic thymectomy approaches, including the subxiphoid technique.
• To emphasize the growing need for thoracic surgeons to develop proficiency in safe and effective thymectomy procedures.

Main Methods:

• Review of established surgical techniques for thymectomy, including extended thymectomy and thoracoscopic approaches.
• Discussion of methods to improve surgical view and access during thoracoscopic thymectomy.
• Consideration of recent findings, such as the MGTX trial, influencing surgical indications.

Main Results:

• Thoracoscopic thymectomy, with or without CO2 insufflation or chest wall lifting, provides adequate surgical views and working space.
• The subxiphoid approach for thoracoscopic thymectomy has demonstrated clinical utility.
• The MGTX trial indicates thymectomy's efficacy in myasthenia gravis patients up to age 65, potentially increasing the number of surgical candidates.

Conclusions:

• Thoracoscopic thymectomy, particularly with the subxiphoid approach, offers a viable and less invasive surgical option for myasthenia gravis.
• The expanding indications for thymectomy necessitate that thoracic surgeons acquire and refine safe and effective surgical skills.
• Continued development and adoption of minimally invasive techniques are crucial for optimal patient outcomes in myasthenia gravis management.
