A 23-year-old man was referred to our hospital because of mild dysphagia to solid food. Computed tomography showed an obvious mass arising from the lower esophagus. In the esophagogastroduodenoscopy examination, a bulging lesion was observed adjacent to the cardia. Endoscopic ultrasound revealed a 4.5x3.8cm hypoechoic cystic lesion without blood flow signal, which affected most of the muscularis propria layer (Fig.1). Given the the high risk of perforation during endoscopic resection, we considered a more minimally invasive treatment was appropriate for this case.

聚桂醇消融治疗食管内大型支气管囊肿一例

一名 23 岁男性因固体食物轻度吞咽困难被转诊至我院。计算机断层扫描显示从食管下段产生的明显肿块。在食管胃十二指肠镜检查中，在贲门附近观察到一个凸起的病变。超声内镜显示 4.5x3.8cm 低回声囊性病变，无血流信号，累及大部分固有肌层（图 1）。鉴于内镜切除术中穿孔的高风险，我们认为更微创的治疗适合这种情况。
