Introduction: Esophageal diverticulum is a rare entity with symptoms that include dysphagia, halitosis, chest pain, and regurgitation. Indications for surgery include the presence of any of these symptoms and a diverticulum larger than 3 cm because of the increased risk of malignancy and aspiration. Treatment is open or minimally invasive surgery performed from the transhiatal or transthoracic approach.
Case description: Three patients were investigated by esophagogastroduodenoscopy, esophageal manometry, and computed tomography and were given the diagnosis of epiphrenic diverticulum of the esophagus.
Management and outcome: The patients underwent robot-assisted surgery by a transthoracic approach for esophageal diverticulectomy. The mean operative time was 211 min, with no significant blood loss or intraoperative complications.
Discussion: This report of robot-assisted surgery for esophageal diverticulectomy from a transthoracic approach adds to the literature regarding surgical treatment of epiphrenic esophageal diverticulum. It is a feasible method that can be used in selected patients with esophageal diverticulum.
