Summary

Objective: To comparatively analyze long-term results and complications of transcervical (TCT) and transsternal thymectomy (TST) in a randomized controlled trial with a mean follow-up of ten years.

Results: Outcomes 10 years after surgery by MGFA post-intervention status showed that complete stable remission was achieved in 8 (21.6%) patients of the TCT group, and in 20 patients (55.5%) of the TST group.

Conclusions: Transcervical and transsternal thymectomy are safe and result in significant improvement of patients with Myasthenia Gravis. TST has superior results in terms of complete stable remission at 10 years.

Interventions

PROCEDURE

Transcervical Thymectomy

Transcervical Thymectomy. All transcervical thymectomies were performed with an 8 cm transversal cervicotomy was performed approximately 2 cm above the sternal notch. Musculocutaneous flaps were developed up to the thyroid cartilage and the suprasternal notch. Strap muscles were split in the middle and retracted laterally. The upper horns of the thymus were exposed and were freed up to the level of the innominate vein. All tributary veins were suture ligated. A sternal retractor was then placed to retract the sternum upward until the patient was nearly lifted off the table. The rest of the Thymus was dissected, from the pericardium and the pleura. Care was specially taken to remove as much fatty tissue adjacent to the thymus as possible preserving the phrenic nerves.

PROCEDURE

Transsternal Thymectomy

Transsternal Thymectomy. A standard formal median sternotomy was carried out. The sternum was retracted laterally using an automatic retractor. All thymic tissue with the adjacent adipose tissue was removed starting with the inferior horns of the thymus. Thymic vessels were ligated and dissection was continued until the upper horns could be separated from the thyroid. A mediastinal tube was placed before closing the sternum and was kept in close suction for 2 to 3 days.
