Objective: To evaluate the clinical value of video-assisted thoracoscopic extended thymectomy for myasthenia gravis(MG).
Methods: Sixty-two MG cases underwent video-assisted thoracoscopic extended thymectomy. The operative extension included thymus tissue and adipose tissue in anterior superior mediastinum.
Results: All operations were performed successfully. The mean operating duration, mean intraoperative blood loss and mean postoperative hospital stay was 98 ± 26 minutes, 60 ± 29 ml and 8.2 ± 2.5 days respectively. All cases were followed up for 5 to 48 months. Among them, 20 (32.3%) patients achieved a complete relief, 32 (51.6%) had their improved symptoms, 8 (12.9%) remained stable and 2 (3.2%) became worse. And the overall relief rate was 83.9%.
Conclusion: Video-assisted thoracoscopic extended thymectomy is both feasible and reliable for MG with the advantages of a minimal trauma and a rapid recovery.

Background And Objective: Thymic epithelial tumors, including thymomas and thymic carcinomas, represent the most common mediastinal tumors and account for up to 50% of all anterior mediastinal tumors. For early stages of these thymic tumors, complete resection of the entire thymus is the recommended treatment. The transition from open surgery to video-assisted thoracoscopic surgery (VATS) and recently to robotic-assisted thoracic surgery (RATS) has fundamentally altered the treatment of thymic tumors.

Descending necrotizing mediastinitis (DNM) is a severe, life-threatening infection that requires prompt diagnosis and aggressive surgical intervention. Management is particularly challenging when the condition is complicated by bilateral empyema and perivascular involvement. A 73-year-old woman presented with septic shock several days after experiencing pharyngeal pain.

Objective: We developed a technique to determine deep surgical margins using radiofrequency identification markers. This study assessed the feasibility of this technique during extended segmentectomy of intersegmental lesions.
Methods: A single-center, prospective, single-arm study was performed from 2020 to 2023.

Article Synopsis
- * Thymomas grow slowly and are localized, while thymic carcinomas grow quickly and can spread, with respective 5-year survival rates of 78% and 30%.
- * Treatment depends on tumor resectability, starting with surgery for early-stage cases, followed by chemotherapy for more advanced stages, while conditions like myasthenia gravis are associated with these tumors and can be treated through various methods, including extended thymectomy.

Minimally invasive thoracoscopic thymectomy has been indicated in patients with non-invasive thymic epithelial tumors or myasthenia gravis. Sub-xiphoid thymectomy has an advantage of similar surgical view of median sternotomy as compare to lateral approach. Since anterior mediastinum is anatomically limited space, robotic approach with carbon dioxide (CO2) insufflation has led a drastic innovation in thymectomy.
