Excision of esophageal duplication cysts with robotic-assisted thoracoscopic surgery.

Esophageal duplication cysts are infrequent anomalies of the gastrointestinal tract that are predominantly found in children. The conventional surgical approach for removal of these cysts is an open surgery one with a posterolateral thoracotomy incision. However, more recently, these cysts have been excised via video-assisted thoracoscopic surgery (VATS). In this article, we present 2 pediatric patients treated with successful excision of an esophageal duplication cyst via robotic-assisted thoracoscopic surgery (RATS) using the da Vinci surgical system. With robotic technology, precise dissection and complete resection of the thoracic mass was achieved without violating the esophageal mucosa. There were no complications, and the patients did not require placement of a postoperative chest tube. Pathological examination of the mass was consistent with an esophageal (foregut) duplication cyst in both cases.
