A 34-year-old woman was referred to our hospital because of the development of dysphagia and weight loss. Esophagogastroduodenoscopy (EGD) showed a submucosal tumor in the middle of the esophagus ([Fig. 1 a]) and endoscopic ultrasonography (EUS) revealed a bilobed cystic lesion within the submucosal layer. Computed tomography (CT) of the chest showed a well-defined, bilobed, cystic mass in the mediastinum.

We performed endoscopic fenestration of the cyst. After we had made an initial incision with a needle knife (Olympus, Tokyo, Japan), brownish liquid contents flowed out of the cyst ([Fig. 1 b]). The cyst was fenestrated with an insulation-tip knife (Olympus) ([Fig. 1 c]; [Video 1]). The patient’s symptoms completely disappeared and there was no evidence of recurrence on repeat EGD 2 months after the procedure ([Fig. 1 d]).

Duplication cysts of the esophagus are rare congenital anomalies that arise from an error in early embryonic development [1]. Duplication cysts are usually asymptomatic and, in most cases, are detected incidentally on a routine EGD. Abu-Zaid et al. previously reported a patient with an esophageal duplication cyst, which was treated by surgical excision [2]; however, treatment for this condition is currently moving from thoracotomy to endoscopic treatments [1]. Endoscopic treatments are considered when EUS demonstrates that cysts are localized within the submucosal layer and do not communicate with the deep muscular layer. Small esophageal duplication cysts can be completely resected with a standard polypectomy snare [3]. For larger cysts, careful fenestration with an insulation-tip knife is safe and effective [4].
