BackgroundThymectomy is a reliable surgical method for treating patients with myasthenia gravis (MG) and benign tumors of the thymus. Despite the advantages of minimally invasive surgical approaches for resection of thymic neoplasms, there are still controversies regarding the superiority of one type of surgery over another.ObjectivesTo report the results of our initial Israeli experience with robotic thymectomy in 22 patients with MG and suspected benign thymic tumors.MethodsWe retrospectively analyzed 22 patients (10 men, 12 women) who underwent robotic thymectomy by a left-sided (16) or right-sided approach (6) using the da Vinci robotic system at Assaf Harofeh Medical Center. Seven patients were diagnosed with MG before surgery and 14 had suspected benign thymic neoplasms.ResultsAverage operative time was 90 minutes. There were no deaths or intraoperative complications. Postoperative complications occurred in two patients (dyspnea and pleural effusion). Median blood loss was 12.3 cc (range 5-35 cc), median hospital stay 2.9 days (range 2-5 days), and mean weight of resected thymus 32.1 grams. Seven patients had thymic hyperplasia, six a lipothymoma, one a thymic cyst. Seven each had thymomas in different stages and one had a cavernous hemangioma.ConclusionsRobotic thymectomy is a safe, technically effective surgical method for resection of thymic neoplasms. The advantages of this technique are safety, short hospitalization period, little blood loss, and low complications. We have included this surgical procedure in our thoracic surgery residency program and recommend a learning curve program of 10 to 12 procedures during residency.
