Subdiaphragmatic Bronchogenic Cyst at the Gastroesophageal Junction Presenting With Dysphagia: A Case Report

Background: Bronchogenic cysts are benign lesions derived from the primitive foregut. They frequently occur in the mediastinum, most commonly at the subcarinal level. Subdiaphragmatic location for bronchogenic cysts is extremely rare. Methods: A 40-year-old woman presented with worsening dysphagia and was diagnosed as a bronchogenic cyst arising from infradiaphragmatic esophagus by computed tomographic scan and endoscopic ultrasound-guided aspiration. Total laparoscopic enucleation of the cystic mass was performed. Results: The postoperative esophagogram revealed no leak or reflux and the patient was discharged on day 2. The histopathologic examination revealed a bronchogenic cyst. No recurrence of the cyst or symptoms was noted at 6 months. Conclusions: Infradiaphragmatic bronchogenic cysts are uncommon and may become symptomatic secondary to compression of surrounding structures. A complete resection by laparoscopy is feasible and represents a safe and minimally invasive alternative to traditional resection through laparotomy or thoracotomy.
