RESUMO
This report discusses the treatment and outcomes of three-port video-assisted thoracoscopic surgery (VATS) thymectomy for thymoma. We reviewed perioperative results of 159 thymoma cases( excluding thymic carcinoma) over 16 years. Thoracoscopic surgery was indicated for Masaoka stagesâ to â ¢, tumor diameter up to 12 cm, and resection of surrounding organs up to the lung, pericardium+reconstruction, internal thoracic artery and vein, left brachiocephalic vein, and phrenic nerve+reconstruction. The mean age of patients was 56.9±12.7, with 71 males and 88 females. The surgical approach was right-sided in 110 cases, left-sided in 47 cases, and bilateral in 2 cases. Total thymectomy was performed in 141 cases, with total thymectomy plus combined resection of other organs (lungs, pericardium, and phrenic nerve) ±reconstruction in 18 cases. The World Health Organization( WHO) classification( 5th edition) was type A/AB/B1/B2/B3/micronodular thymoma with lymphoid stroma (MNTLS) = 20/49/32/45/11/2, and Masaoka classification was stageâ /â ¡/â ¢=69/86/4. The three-port VATS technique offers several advantages, including its applicability to other surgeries, avoidance of contralateral thoracic cavity opening, safety in thymectomy without open conversion, and a mean postoperative hospital stay of 3 days.
