Abstract
Background: The standard treatment for thymomatous myasthenia gravis (TMG) patients is thymectomy, whereas its role in non-TMG (NTMG) is still under debate. The objective of this study is to assess myasthenia gravis (MG) outcomes of thymectomy using the uniportal video-assisted thoracoscopic surgery (UVATS) technique for both groups and evaluate the procedure's efficacy and safety.
Methods: We retrospectively collected data from January 2019 to December 2022 at Hospital Kuala Lumpur. The Myasthenia Gravis Activities of Daily Living (MG-ADL) scoring and the Myasthenia Gravis Foundation of America's Post Interventional Score (MGFA-PIS) measured our primary outcome. Secondary outcomes included surgery-related morbidity. All patients underwent a UVATS thymectomy, with the incision at the right anterior axillary line at the 5th intercostal space.
Results: Out of 26 patients, 22 were analysed. The MG-ADL scores indicated a significant mean score reduction post-surgery [6.9; 95% confidence interval (CI): 4.42 to 9.67; P<0.001]. NTMG patients exhibited a greater decrease in MG-ADL mean score than TMG patients {9.5 [standard deviation (SD) 4.8] vs. 6.1 (SD 5.4) P<0.001}. The MGFA-PIS showed complete stable remission (CSR) rates of 43% for TMG and 25% for NTMG patients. Surgical morbidity was observed in 13% of patients, of which were myasthenic crisis, difficult extubation due to carbon dioxide (CO2) retention and subcutaneous emphysema.
Conclusions: Thymectomy via UVATS is an effective and safe approach for improving symptoms in both TMG and NTMG patients.
