The study explored the feasibility and safety of modified subxiphoid thoracoscopic thymectomy for patients with locally invasive thymomas. The use of an auxiliary sternal retractor during the procedure resulted in good recovery postoperatively without serious complications.
Background. We explored the feasibility and safety of modified subxiphoid thoracoscopic thymectomy for patients with locally invasive thymomas. Methods. Subxiphoid thoracoscopic thymectomy was performed on select patients with locally invasive thymomas (Masaoka stage III) using an auxiliary sternal retractor to create a larger operative field. Results. From June 2015 to March 2019, we performed modified subxiphoid thoracoscopic thymectomy on 48 patients with locally invasive thymomas: 39 patients had pericardium or lung infiltration and received a combination of a partial pericardium or lung wedge resection, and 9 patients had left innominate vein infiltration and underwent combined resection of the left innominate vein. Thoracoscopic thymectomy was performed from the subxiphoid pathway with an auxiliary sternal retractor in all 48 patients, and there were no conversions to median sternotomy. The median tumor size was 5 cm, and the maximal tumor size was 12 cm. The median blood loss was 50 mL. The median duration of chest tube placement was 3 days, and the median hospital stay was 4.5 days after surgery. All patients achieved a good recovery after surgery, and none had serious complications during the perioperative period. All patients underwent postoperative adjuvant radiotherapy and presented no local recurrence or distant metastasis until now. Conclusions. Modified subxiphoid thoracoscopic thymectomy with an auxiliary sternal retractor makes minimally invasive thymectomy easier and safer to perform and is an alternative approach for some patients with locally invasive thymomas.
