Thoracoscopic enucleation of a submucosal bronchogenic cyst of the esophagus: report of two cases.

Thoracoscopic enucleation of a bronchogenic cyst of the esophagus was successfully performed in two cases. The first patient was a 26-year-old female complaining of dysphagia and retrosternal discomfort. The second patient was a 56-year-old female complaining of retrosternal discomfort. A close examination revealed a cystic lesion compressing the esophagus in both cases. Three trocars were employed under general anesthesia. Thoracoscopy offering excellent visualization allowed us to perform a precise anatomical dissection between the muscle layer and the mucosa. Both patients recovered uneventfully and the symptoms disappeared postoperatively. Thoracoscopic surgery is thus considered to be beneficial for the treatment of a benign esophageal tumor because of the small chest wall entry, which might positively contribute to a favorable postoperative course.
