摘　　要：目的探索颈、胸段完全性脊髓损伤后肛门直肠功能障碍对排便的影响。方法利用肛门直肠动力检测仪 ,对照比较30例颈、胸段完全性脊髓损伤患者和 30例正常人排便时肛门直肠动力学参数的变化。结果颈、胸段完全性脊髓损伤患者排便时肛管压力下降幅度、直肠 -肛管压力梯度和排便指数小于正常人 (P<0 .0 1)。结论脊髓损伤破坏了用力排便时肛门直肠活动的协调性 ,使自主排便机制受损 ,非自主排便成为主要排便机制。ObjectiveTo investigate changes of anorectal dysfunction in patients with complete cervical and thoracic spinal cord injury.Methods30 hospitalized cases with complete spinal cord injury and 30 healthy volunteers were performed with anorectal manometry. Changes of manometric characteristics of anorectal and sphincter function were recorded when subjects were resting and bearing down.ResultsDuring defecation, the decreased amplitude of the anal pressure, the pressure gradient between rectal and anal and the index of defecation in patients with complete spinal cord injury were lower than that of in healthy volunteers ( P<0.01).Conclusions The anorectal coordination during attempting to defecate and mechanism of initiative defecation were impaired. The mechanism of the reflectivity defecation was the main approach to defecate for patients with complete cervical and thoracic spinal cord injury.
