目的观察功能性吞咽困难(FD)患者食管动力改变,探讨其病理生理基础。方法 FD患者69例,采用SGY-3型消化道多功能检测仪,吞水试验测定食管体部运动功能,缓慢牵位法测定食管上下括约肌功能。结果功能性吞咽困难患者,女性多见,占67%,26%食管上括约肌松弛不全,平均松弛压1.45 kPa(范围1.0-4.0 kPa)。食管体部呈高幅蠕动。下段食管蠕动时间缩短,食管体部传导速度减慢,同步收缩明显增加。食管下括约肌静息压下降。9例患者最后诊断为反流性食管炎;3例缺铁性贫血;5例慢性咽炎;6例Ⅱ型糖尿病;其余患者病因不明。结论功能性吞咽困难患者食管动力改变是非特性的,许多患者存在有潜在疾病,因此应积极寻找病因。
Objective To observe the changes of esophageal motility in patients with functional dysphagia (FD) and to explore its pathophysiological basis. Methods Sixty-nine patients with FD were enrolled in this study. SGY-3 gastrointestinal multifunction detector was used. The motility function of the esophagus was measured by swallowing test and the function of upper and lower esophageal sphincter was measured by slow traction method. Results Functional dysphagia patients, more common in women, accounting for 67%, 26% upper esophageal sphincter relaxation, the average relaxation pressure of 1.45 kPa (range 1.0-4.0 kPa). Esophageal body was high amplitude peristalsis. Lower esophageal peristalsis time shortened esophageal body conduction velocity slowed systolic significantly increased. Lower esophageal sphincter pressure drops. Nine patients were finally diagnosed as reflux esophagitis; 3 cases of iron deficiency anemia; 5 cases of chronic pharyngitis; 6 cases of type 2 diabetes; the remaining patients etiology is unknown. Conclusion Esophageal motility changes in patients with functional dysphagia are non-specific and many patients have underlying diseases. Therefore, we should actively look for the cause.
