老年特发性便秘直肠肛门压力测试59例分析

目的　探讨老年慢性特发性便秘 (CIC)患者直肠肛门运动功能变化 ,　 方法 　采用瑞典Medtronic公司生产的 8通道水灌注式消化道压力检测系统对 5 9例老年CIC患者及 36例老年对照者进行直肠肛门压力测定。　 结果 　老年CIC患者最大缩榨压、模拟排便时肛管压力变化低于老年对照组 (P <0 0 5 ) ,直肠初始感觉阈值、排便阈值和最大耐受容量均高于老年对照组 (P <0 0 5 ) ,2 8例 (47 5 % )老年CIC患者模拟排便时出现肛管压力异常升高。　 结论 　老年CIC与直肠低敏感、高耐受及排便时直肠肛管运动不协调有关

Changes of anorectal dynamics in elderly patients with chronic idiopathic constipation

Objective To investigate the anorectal dynamic abnormality in elderly patients with chronic idiopathic constipation(CIC). Methods Study was performed in 59 elderly patients with CIC and 36 elderly healthy subjects (EHS).Anorectal pressure was measured with Medtronic PcPolygraf,which was a water perfused catheter system. Results Maximal squeezing pressure and the changes of anal pressure during defecation in elderly patients(EP) with CIC was lower than those in EHS(P<0.05).The rectal initial sensation threshold volume,the rectal threshold volume for desire to defecate and the rectal maximal volume of tolerance were higher than those in EHS(P<0.05).And there were 28(47.5%) of EP who had increased anal pressure when defecation was stimulated. Conclusions Senile CIC may be associated with lower sensitivity,higher tolerance and disco ordination of anorectum during defecation.
