Abstract: Objective: To determine the current role of Video-Assisted Thoracic Surgery (VATS) in the diagnosis and treatment of benign lung tumors and tumoral lesions. Methods: 107 thoracoscopic procedures were performed in 103 patients between Oct. 1992 and Oct. 2002. Among them 62 were males and 41 females, with mean age of 41.9 years (range 13-71 years). These consisted of left VATS in forty-eight patients, right VATS in fifty-one and bilateral VATS in 4 patients. A total of 114 tubers were resected. Results: All patients got definitive pathologic diagnosis and all tubers were resected with VATS, Eight of them were assisted with minimal thoracotomy and 4 were converted to thoracotomy. All patients recovered uneventfully. The average postoperative hospital stay was 4.8 days. There were no incidence of postoperative complication and mortality. Conclusion: The result of this study suggests that VATS is an acceptable approach in the diagnosis and Treatment of benign lung tumors and tumoral lesions.
