Abstract
A case of thoracoscopic resection of a esophageal duplication cyst is reported. An 18-year-old woman was seen at the hospital because of epigastralgia, Chest roentgenogram and CT scan revealed a mediastinal tumor. Chest CT showed a 3cm in diameter cystic tumor at the left side of the lower esophagus. Endoscopic ultrasonography was suggestive of esophageal cyst, therwfore, thoracoscopic resection of the tumor was performed. To prevent recurrence, the residual mucosa was cauterized as well. The tumor contained viscosous and mucinous mucus. The postoperative pathologic diagnosis was esophageal duplication cyst. Thoracoscopic resection is thought to be necessary for differential diagnosis of cysts of unknown origins, and that because the esophageal duplication cyst is a benign tumor, it is a good indication for thoracoscopic resection.
