目的 探讨食管憩室的胃镜下表现和临床特点。方法 对2010年4月至2015年1月在我科经胃镜诊断的28例食管憩室 的患者临床资料进行回顾性分析，观察食管憩室的临床症状。结果 食管憩室患者有18例无任何症状，占临床表现 的64%，4例患者咽下困难，为14%，3例患者有食管异物感，占11%，3例患者胸骨后疼痛，为11%；患者经胃镜检查 后表现为咽食管憩室的有9例（32%）、食管中段憩室的有15例（54%）、膈上憩室的有4例（14%）；食管憩室直径 ＜1.0cm的有20例（71%）、介于1.0-3.0cm之间的有5例（18%）、＞3.0cm的有3例（11%），所有患者食管憩室表面 粘膜均无充血水肿糜烂，有液体及少许食物残留的有13例，均可冲洗干净。结论 食管憩室一般无症状，多发于食 管中段，大多数患者无明显食管症状，并发症较少，并且憩室大小与患者年龄有正相关联系。

Objective To investigate the clinical and endoscopic features of esophageal diverticulum performance. Methods The April 2010 to 2015 years 1 month in our department by gastroscopy in the diagnosis of 28 cases with esophageal diverticulum in patients with clinical data were retrospective analysis, observe the clinical symptoms of esophageal diverticulum. Flushing liquid erosion (between the results of esophageal diverticulum patients 18 cases without any symptoms, accounting for clinical manifestations of 64%, 4 cases of patients with pharyngeal dysphagia is 14%, 3 cases of patients with esophageal foreign body sensation, accounting for 11%, 3 cases of patients with substernal pain, 11%; patients with gastroscopy showed pharyngoesophageal diverticulum in 9 cases (32%), esophageal diverticulum of 15 cases (54%) and phrenic diverticulum in 4 cases (14%); esophageal diverticulum diameter < 1.0cm of 20 patients (71%), between 1.0-3.0cm 5 cases 18% and > 3.0 cm in 3 cases (11%), all patients with esophageal diverticulum mucosal surfaces were no hyperemia, edema, and a little food residue of 13 cases, can clean. Conclusion Esophageal diverticulum is generally asymptomatic, mainly in the middle third of the esophagus, most of the patients had no obvious esophageal symptoms, less complications and diverticulum size and age of the patients have positive correlation.
