Abstract
Background
Robotic technology has facilitated the evaluation and treatment of anterior mediastinal pathology. We describe a 3-year experience using the da Vinci Robotic Surgical System to perform thymectomies for a range of diseases.
Methods
From March 2002 to November 2004, 9 patients (3 myasthenia gravis, 3 mediastinal mass, 2 myasthenia gravis plus thymoma, 1 hyperparathyroidism) underwent totally endoscopic robotic thymectomy. Medical records and operative databases were reviewed. The cohort was divided into an early experience (group A) and a later experience (group B). Data were analyzed with the Fisher exact test and Mann-Whitney test.
Results
Complete robotic resection of the thymus was accomplished in all 9 patients. The mean age for the entire cohort was 40 ± 12 years (range 28–66 years) and 78% of the patients were women. No significant differences in age, gender, or operative conversions were detected between the groups. Patients in group A were more likely to have a bilateral approach. Group B demonstrated statistically significant reductions in operating room and operation time and a trend toward decreased chest tube days and length of stay. No morbidity or mortality associated with the procedure was noted in either group.
Conclusions
Robotic thymectomy is a safe and effective procedure. Its steep learning curve promises to allow more surgeons to adopt minimally invasive approaches to the mediastinum safely and efficiently.
