Esophageal bronchogenic cyst treated with submucosal tunneling endoscopic resection: two case reports.

introductionAlthough esophageal bronchogenic cysts are benign diseases, they may be accompanied by serious complications and have the possibility of recurrence. Therefore, once confirmed, it is necessary to treat the esophagobronchial cyst when the contraindication is excluded. Endoscopic treatment is usually used for lesions with small diameter and shallow origin, and has the advantages of small surgical trauma and risk, which can reduce the psychological burden of patients to a certain extent, help them to recover quickly, and lower hospital costs. CASE PRESENTATION: Case 1 is a 54-year-old Han Chinese man admitted to our hospital who complained of difficulty swallowing in the past 6 months. Case 2 is a 41-year-old Han Chinese man who was hospitalized in the past 3 months due to chest discomfort. Endoscopic ultrasound revealed a hypoechoic cystic lesion arising from the muscularis propria. Submucosal tunneling endoscopic resection was performed using a dual knife, and a cystic mass was observed between the mucosa and the muscular layers of the esophagus. On locating the cyst, an incision was made on the oral side of the lesion for evacuation. The cyst wall was excised using endoscopic argon plasma coagulation. We successfully removed the esophageal bronchogenic cyst lesion in the intrinsic muscle layer using submucosal tunneling endoscopic resection.

conclusionEsophageal bronchogenic cysts are rare in clinical practice and lack specificity in clinical manifestations. Multiple methods can be used to determine the location and nature of the lesion and ultimately determine the treatment plan. Surgical resection and endoscopic treatment are two different treatment methods, and appropriate treatment plans need to be selected on the basis of the origin layer, size, and relationship with the esophagus of the lesion to reduce complications and improve prognosis.
