Diagnosis and treatment of gastric bronchogenic cyst attaching to lesser curvature

Gastric bronchogenic cysts （GBCs） is uncommon with atypical clinical features. It is difficult to diagnose by preoperative imaging examinations. Therefore, postoperative histopatho-logical examination is regarded as the golden bacteria in ultimate diagnosis. The treatment of GBCs： ultrasound⁃guided fine needle aspiration and endoscopic mucosal resection is only used for small GBCs with intra⁃cavity growth pattern. However, GBCs with extra⁃cavity growth pattern is featured with deeply anatomical position, large size, and prone on attaching to vital blood vessels and organs, which makes laparoscopic resection is the first choice in treatment. The authors introduce the diagnosis and treatment of a case of GBCs attaching to lesser curvature, in order to provide references for clinical diagnosis of GBCs.
