Complete thoracoscopic enucleation of the esophageal leiomyoma at the level of the azygos vein: A case report

Benign tumors of the esophagus are rare. Among them, leiomyomas are common. Surgical enucleation is indicated in cases, which have symptoms or large tumors. The enucleation through video assisted thoracoscopic surgery has been developed as a preferred approach for the majority of lesions in recent years. However, the complete thoracoscopic enucleation for an esophagus leiomyoma at the level of the azygos vein without cutting the vein and nor using artificial pneumothorax by CO(2) insufflations is a challenge for thoracic surgeons. This case report was a 64-year-old female who presented dysphagia and chest pain. Chest computed tomography and esophageal endoscopy displayed an esophageal mass. We used complete thoracoscopic enucleation to treat this condition. The tumor was at the level of the azygos vein. Therefore, it was difficult to remove the tumor without cutting the azygos vein without utilizing the artificial pneumothorax. However, we enucleated it completely with no complications. The complete thoracoscopic enucleation of the esophageal leiomyoma at the level of the azygos vein without cutting the vein without using the artificial pneumothorax should be applied. A methylene blue swallowing study is an alternative method to a barrium swallowing study while the chest tube is still placed in the pleural space.
