Discussion: Esophageal leiomyoma accounts for 60 –70% benign tumors of the esophagus and less than 1% of all esophageal neoplasms. Up to 50% of patients are asymptomatic and incidentally diagnosed. Symptomatic patients present with dysphagia, heartburn, regurgitation, retrosternal pain. Barium swallow, CT scan with oral contrast and endoscopic ultrasound represent the mainstay of diagnosis. The use of biopsy is controversial and is recommended in cases of diagnostic doubt. Surgery is indicated in symptomatic patients or with tumors > 5cm, or with unclear biological behavior. Thoracoscopy and thoracostomy are standard surgical approaches for upper and middle third tumors. Minimally invasive techniques can be used regardless of the size of the lesion, although lesions > 5cm carry a high risk of conversion to an open surgical. Right surgical approach could create more operating space and avoid affecting the heart and major vessels. Myotomy reapproximation is recommended to prevent loss of peristalsis, bulging of the mucosa and pseudodiverticulum.
Final considerations: Esophageal leiomyomas are rare and, in most cases, do not require surgical intervention. Thoracoscopy approach should be the first choice, whenever is possible, and performed by an experienced surgeon.
