Esophageal bronchogenic cysts are rare, and since a limited number of cases has been reported, the treatment plan for asymptomatic patients is difficult. A 55-year-old man without any symptoms visited our hospital for further examination of an esophageal mass detected on simple computed tomography. Upper endoscopy showed the protruding, submucosal mass covered by normal mucosa, and endoscopic sonography confirmed hypoechoic lesions originating from the muscularis propria. The patient was diagnosed as having an esophageal duplication cyst and underwent thoracoscopic resection. Pathological findings were consistent with an esophageal bronchogenic cyst. The patient was discharged without any problems on the 6th postoperative day. Upper endoscopy was performed 6 months after surgery, and no evidence of esophageal diverticula or narrowing was present. In conclusion, early thoracoscopic resection of esophageal bronchogenic cysts, before appearance of the symptom, can be a considerable treatment option because it is less invasive and may be advantageous for obtaining a definitive diagnosis in patients who are candidates for safe surgical resection.

食管支气管囊肿很少见，由于报道的病例数量有限，无症状患者的治疗计划很困难。一名没有任何症状的 55 岁男性到我院就诊，以进一步检查通过简单计算机断层扫描检测到的食管肿块。上消化道内镜显示突出的黏膜下肿块被正常黏膜覆盖，超声内镜证实起源于固有肌层的低回声病变。患者被诊断为食管重复囊肿并接受了胸腔镜切除术。病理结果与食管支气管囊肿一致。患者术后第 6 天顺利出院。手术后 6 个月进行了上消化道内镜检查，没有发现食管憩室或狭窄的证据。
