摘要
目的 研究老年慢性特发性便秘患者肛门直肠动力学及感觉阈的变化 ,探讨老年便秘的特点及治疗方法。方法 采用 8导水灌注压力检测系统 ,对 31例老年便秘患者进行肛门直肠测压 ,应用气囊扩张检测其感觉阈值。同时检测 10例健康老年人作为对照。结果 患者组与对照组相比 :肛管静息压、肛门括约肌功能长度均无显著性差异 (P>0 .0 5 ) ;肛门括约肌静息压显著高于对照组 (P<0 .0 5 ) ;肛管最大缩窄压明显低于对照组 (P<0 .0 1) ;直肠肛门松弛率显著低于对照组 (P<0 .0 5 ) ;直肠初始感觉阈和最大耐受量均显著高于对照组 (P<0 .0 1)。结论 老年慢性特发性便秘患者存在明显直肠动力与感觉障碍。治疗方法应采用饮食、促动力药物以及直肠生物反馈等物理手段相结合的综合治疗为宜。
Objective To explore the characters and the treatment in the old patients with constipation by studying their anus and rectum motivity and sensory threshold value.Methods Eight-lead water perfusion pressure measurement system was used to determine the pressures in anus and rectum.Ballonet dilator was used to measure the sensory threshold value of anus and rectum.Ten healthy old person without constipation were made as control.Results The anus rest pressure and the functional length of anus sphincter had no significant difference between the patients and the controls(P>0.05).The maximal constriction pressure and rectum relaxation rate in the patients were lower than that in the controls significantly(P<0.01,<0.05).The rectum sensory threshold value and the maximal tolerance value in the patients were higher than that in the controls significantly(P<0.01).Conclusion The rectum motivity and sensitivity disorders exist in the old patients with chronic idiopathic constipation remarkably.It is characterized by slow movement and unharmonious defection.Most patients have mixed constipation.The treatment should include diet,drugs and rectum feedback.
