【目的】探讨食管测压在诊断弥漫性食管痉挛（DES ）中的价值。【方法】回顾性分析2013年6月至2014年6月本院收治的84例DES患者食管测压结果，并与胃镜检查及钡餐检查进行对比分析。【结果】70例DES患者中有食管体部压力增高，湿咽成功率低，而下食管括约肌压力正常，其诊断率为83．3％，而胃镜检查中22例DES患者可见明显环状收缩，其诊断率为26．2％（22／84）；食管钡餐检查中20例出现下2／3食管出现痉挛，其诊断率为23．8％（20／84）。【结论】DES患者多有胸痛、吞咽困难，食管测压是诊断DES较为准确的方法，并能对DES严重程度作出正确判断。“,”[Objective]To explore the value of esophageal pressure in the diagnosis of diffuse esophageal spasm (DES) .[Methods] Retrospective analyses were conducted for 84 cases of DES with esophageal pressure results from June 2013 to June 2013 at our hospital .And the findings of gastroscopy and barium meal examination were analyzed .[Results]Among them ,70 cases of DES had an elevation of esophageal body pressure with a low success rate of wet swallowing and a normal esophageal sphincter pressure .And the diagnostic rate was 83 .3% .In 22 patients with DES ,gastroscopy revealed annular contraction and the diagnostic rate was 26 .1% (22/84) .On esophageal barium meal examination ,20 cases had an involvement of lower two‐thirds with a diagnostic rate of 23 .8% (20/84) .[Con‐clusion]Many DES patients experience chest pain and difficulty swallowing .And measuring esophageal pressure is accurate in the diagnosis of DES and may help judge its severity .
