摘 要:目的探讨动态采集法排粪造影对直肠内脱垂(internal rectal prolapse,IRP)的诊断价值。资料与方法回顾性分析469例出口梗阻性便秘患者的常规和动态排粪造影表现,统计IRP的显示率。采用χ2检验比较两种方法的显示率。结果动态采集法发现IRP392例,显示率94%(392/417);常规法发现IRP54例,显示率56.25%(54/96);两种方法差异有统计学意义(χ2=97.94,P<0.01)。结论动态排粪造影能提高IRP的显示率,可准确显示病变程度,为临床提供更可靠的治疗依据,可作为出口梗阻性便秘检查的首选。Objective To discuss the diagnostic value of dynamic defecography in internal rectal prolapse.Materials and Methods 469 patients with constipation caused by outlet obstruction underwent conventional and dynamic defecography.The display rates of internal rectal prolapse using the two methods were compared.Results The dynamic defecography displayed 392 cases of internal rectal prolapse(94.00%,392/417)and the conventional defecography displayed 54 cases(56.25%,54/96).The display rate had significant difference between the two methods(χ2=97.94,P0.01).Conclusion The dynamic defecography can improve the display rate of internal rectal prolapse and show the degree of pathological changes.The dynamic defecography should be recommended as the first-choice examination for constipation caused by outlet obstruction.
