摘      要：BACKGROUND Bronchogenic cysts are congenital lesions requiring radical resection because of malignant potential.However,a method for the optimal resection of these cysts has not been completely elucidated.CASE SUMMARY Herein,we presented three patients with bronchogenic cysts that were located adjacent to the gastric wall and resected laparoscopically.The cysts were detected incidentally with no symptoms and the preoperative diagnosis was challenging to obtain via radiological examinations.Based on laparoscopic findings,the cyst was attached firmly to the gastric wall and the boundary between the gastric and cyst walls was difficult to identify.Consequently,resection of cysts alone caused cystic wall injury in Patient 1.Meanwhile,the cyst was resected completely along with a part of the gastric wall in Patient 2.Histopathological examination revealed the final diagnosis of bronchogenic cyst and revealed that the cyst wall shared the muscular layer with the gastric wall in Patients 1 and 2.In Patient 3,the cyst was located adjacent to the gastric wall but histopathologically originated from diaphragm rather than stomach.All the patients were free from recurrence.CONCLUSION The findings of this study state that a safe and complete resection of bronchogenic cysts required the adherent gastric muscular layer or full-thickness dissection,if bronchogenic cysts are suspected via pre-and/or intraoperative findings.
