【摘要】 目的：明确食管及其下括约肌长度在胃食管反流疾病中的变化及临床意义。方法：用灌注式多导测压系统对正常组６３例受试者及胃食管反流组５３例病人进行食管压力测定。结果：正常人各年龄组食管下段括约肌长度差异无显著性；胃食管反流性疾病组食管下段括约肌长度及腹段下括约肌长度均显著下降；正常组与胃食管反流性疾病组身高与食管长度的相关系数分别为ｒ１＝０．７００，ｒ２＝０．７９８。结论：食管下括约肌长度在抗反流中起到重要作用，其在正常人群中不随年龄而变化；胃食管反流性疾病患者未伴食管长度缩短、上提更多还原

【Abstract】 Objective: To investigate the changes of esophageal and lower esophageal sphincter length in gastroesophageal reflux disease (GERD). Methods: PC Polygraf system was used to measure esophageal intraluminal pressure on 63 normal cases and 53 GERD cases with four channel tube assembly. Results: In normal cases the length of lower esophageal sphincter in different age groups had no significant difference. In GERD group the length of lower esophageal sphincter and intra abdominal sphincter obviously decreased. The related coefficient between esophageal length and body length in normal and GERD groups was 0.700 and 0.798, respectively. Conclusion: The length of lower esophageal sphincter was important in anti reflux; it did not change with ages in normal group; GERD did not induce shortening of length of esophagus.更多还原
