Symptoms of this disease are reported to be asymptomatic in approximately 70% but include respiratory symptoms such as coughing and difficulty breathing. Minimally invasive removal of these cysts without esophagectomy is typically recommended. However, when the cyst is situated in the upper mediastinum, surgical excision becomes technically challenging. Here, we report a case of an obese female patient with esophageal duplication cyst in the upper mediastinum who underwent successfully robotic-assisted complete removal of the cyst. A 50-year-old woman presented to a local clinic with a persistent cough and hoarseness lasting 4 months. A computed tomography scan revealed a large cystic tumor in the upper mediastinum, causing displacement of the trachea. The resection of the cystic tumor was safely performed with robotic assistance. The use of robotic system for the removal of esophageal duplication cyst is technically safe and feasible.
