摘要
目的探索老年功能性便秘患者肛门、直肠运动功能的变化。方法采用气囊测压管检测３０例老年功能性便秘患者的肛门、直肠运动功能，并以健康人及非老年功能性便秘患者作对照观察。结果（１）老年健康人肛门内括约肌静息压、最大缩窄压、肛管直肠屏障压、肛管括约肌长度分别为１０．１±３．０、１４．７±２．３、８．０±２．８ｋＰａ和２．３±０．４ｃｍ，低于非老年健康组（Ｐ＜０．０５或０．０１）；而直肠最低敏感量、最大顺应性（９２±４８、３４±１０ｍｌ／ｋＰａ）高于非老年健康组（Ｐ＜０．０５）。（２）老年便秘组肛管直肠屏障压、直肠最低敏感量、最大耐受性、最大顺应性和内括约松弛压为１０．５±３．０ｋＰａ，１０６±４２、２６０±５０ｍｌ、３７±１５ｍｌ／ｋＰａ和５．９±１．０ｋＰａ高于老年健康组（Ｐ＜０．０５或０．０１）。（３）老年便秘组直肠肛管屏障压、肛管括约肌长度和肛门内括约肌最大缩窄压小于非老年便秘组（Ｐ＜０．０５）。结论老年健康人有直肠、肛门运动功能紊乱，便秘与直肠低敏感、高耐受、高顺应性。
Objective To study the changes of anorectal motility in the healthy elderly and elderly patients with functional constipation (FC). Methods Anorectal motility was investigated by multispot ballon probe in 30 healthy elderly subjects (HE), 15 nonelderly healthy subjects (NEHS), 30 elderly and 30 nonelderly patients with FC. Results 1. The static pressure and maximal squeeze pressure of internal anal sphincter (IASMSP), the anorectal barrier pressure (ABP) in HE (101±30,147±23,80±28kPa respectively) were lower than those in NEHS (P<005 or 001). The length of anal sphincter high zone (ASHL)in HE (23±04cm) was shorter than that in NEHS. The rectal lowest volume of sensory threshold (RLSTV), the maximal compliance (MC) in HE (92±48, 34±10ml/kPa) were higher than those in NEHS (P<005). 2.ABP, RLSTV, the rectal maximal volume of tolerance, MC, the relaxative pressure of internal anal sphincter in elderly patients with FC 105±30kPa,106±42,260±50ml、37±15ml/kPa,59±10kPa) were higher than those in HE and NEHS (P<005 or 001).3.ABP, ASHL and IASMSP in elderly patients with FC were lower than those in nonelderly patients with FC. Conclusions 1. There are some anorectal motility disturbances in HE which form the basas of pathopysiology for HE easy to suffer from FC. 2. FC in elderly and nonelderly patients may be associated with lower sensitivity, higher tolerance and compliance of rectum and poor relaxation of internal anal sphincter.
