[Diagnosis and treatment of mediastinal tumor by VATS].

Twenty-eight patients with mediastinal tumors underwent thoracoscopic operation, among which 22 received the resection of mediastinal tumor including mediastinal cyst (9), teratoma (5), neurogenic tumor (5), thymoma (1), vagothyrophyma (1), and lipoma (1), and 6 patients received diagnostic biopsy of mediastinal tumor. The preliminary results were promising. The experience of thoracoscopic operation on mediastinal tumor are discussed in this article and VATS is regarded as a new diagnostic and treating method which is superior to conventional thoractomy on some kinds of mediastinal diseases.
