Methods: Of 11 patients with endoscopically detected SMTs in the thoracic esophagus, 6 underwent thoracoscopic enucleation and were endoscopically followed up. Results: The thoracoscopically enucleated tumors were 3 leiomyomas, 2 schwannomas, and 1 gastrointestinal stromal tumor. Five tumors were not removed surgically but showed no enlargement over 3years (range 42-84months); 4 of these tumors were histologically diagnosed as leiomyomas by fine-needle aspiration analysis or routine biopsy. All patients who underwent thoracoscopic enucleation had dietary symptoms preoperatively, whereas those who did not undergo it were asymptomatic. Tumor size ranged from 30 to 45mm for the surgical cases. In cases in which preoperative endoscopic biopsy was performed, the tumors were found to be adherent to the esophageal mucosa during enucleation surgery; however, neither mucosal injury nor postoperative leakage occurred. SMTs not treated by thoracoscopic enucleation were <15mm in diameter and showed no enlargement over a long-term follow-up period. No differences in clinical features, excluding schwannoma and GIST, were noted between cases with and without therapeutic enucleation. Conclusion: Thoracoscopic enucleation is useful and safe for the removal of thoracic esophageal SMTs ranging from 30 to 50mm in diameter. Leiomyomas of the thoracic esophagus <20mm in diameter may be followed up endoscopically in asymptomatic cases.
