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 investigate the characteristics of normal proximal pediatric esophageal manometry. Methods: Six hundred normal children underwent esophageal manometry with a computerized gastrointestinal manometry system, aged 3 to 12 years. Results: The pharyngeal resting pressure was 0.67 ± 0.19 kPa, the swallowing systolic pressure was 1.99 ± 0.57 kPa and the systolic time was 0.5 second. The pressure of the proximal esophageal sphincter (UES) varied greatly with the state of the child. The resting pressure of UES was 2.66 ~ 10.64 kPa, UES systolic pressure was 7.98 ~ 15.96 kPa, proximal esophageal sphincter length (UESL) was 1.50 ± 0.42 cm. The proximal esophageal resting pressure was 0.11 ± 0.27 kPa, systolic pressure was 7.32 ± 2.99 kPa, and conduction velocity was 25-90 mm / s. The group under the sober proximal esophageal manometry success rate was 80%.
