Large bronchogenic cyst of stomach, a case report of a rare congenital anomaly as an incidental finding during bariatric surgery.

INTRODUCTION AND IMPORTANCE

Bronchogenic cysts are rare congenital anomalies of the foregut that occur as a result of abnormal budding during early embryogenesis.

CASE PRESENTATION

Here, we present a 21-year-old woman with a BMI of 47 who was candidate for one anastomosis gastric bypass surgery. During the operation we found two large cystic structures originating from gastric fundus and gastroesophageal junction as an incidental finding. So plan of surgery shifted to the sleeve gastrectomy as we had to remove the cysts while operating. Histological examination confirmed the bronchogenic origin of the cyst, with IHC confirmation.

CLINICAL DISCUSSION

Although bronchial cysts are often asymptomatic, just like our reported case, the clinical manifestations of abdominal bronchogenic cysts depend on their size and location. If the cyst enlarges, it may compress adjacent organs, leading to abdominal pain, difficulty swallowing (dysphagia), or even bowel obstruction.

CONCLUSION

Since the diagnosis of bronchogenic cysts is challenging preoperatively in individuals with obesity, every bariatric surgeon should have sufficient mental preparation to adopt the appropriate surgical method when faced with this case.
