正常小儿近端食管功能的测压研究

The Upper Esophageal Manometric Study in Normal Children

目的:探讨正常小儿近端食管测压的特点。方法:应用计算机消化道测压系统,对60例正常小儿进行了食管测压,年龄3～12岁。结果:咽部静息压为0.67±0.19 kPa,吞咽收缩压力为1.99±0.57 kPa,收缩时间为0.5秒;近端食管括约肌(UES)压力随小儿状态不同有很大差异,UES 静息压为2.66～10.64 kPa,UES 收缩压为7.98～15.96 kPa,近端食管括约肌长度(UESL)为1.50±0.42 cm。近端食管体部静息压为0.11±0.27 kPa,收缩压为7.32±2.99 kPa,传导速度为25～90 mm/s。本组小儿清醒状态下近端食管测压的成功率为80%。

Objective:To observe the physiological character of upper esophagus in normal children.Methods:Sixty children aged 3 to 12 years received upper esophagus monitoring by ali- mentary tract manometer computer system.Results:The pharyngeal resting pressure was 0.67± 0.19 kPa,peak contraction pressure 1.99±0.57 kPa.The contractive time was 0.5 seconds.The upper esophageal sphincter(UES)pressure had significantly varied with the different status of the child.UES resting pressure varied from 2.66～10.64 kPa,and UES contractive pressure was 7.98 ～15.96 kPa.The length of UES was 1.5±0.42 cm.The conductive speed was 25～90 mm/sec. Conclusions:The esophageal manometry is a useful technique to monitor esophageal function,as- sist the diagnosis and evaluate the efficacy of treatment.
