摘　　要：目的探讨应用动静态结合仿真排便造影技术在便秘病因诊断中的应用价值。方法 对50例便秘的患者先行常规清洁肠腔，侧卧位经肛门注入自制仿真排便造影剂，充盈直肠、乙状结肠及部分降结肠，然后侧位坐于特质便桶上，调整好高度使左右股骨重合，显示耻骨联合及尾骨，以4帧／s的采集速度进行动态采集图像，然后对直肠、肛管动态变化进行分析测量。结果该组50例患者，直肠前突32例，直肠折曲1例，肛管狭窄2例，直肠黏膜脱垂7例，盆底痉挛综合征4例，未找出便秘病因4例。结论动静态结合仿真排便造影检查对便秘患者的病因诊断具有重要作用。Objective To explore the applied value of static and dynamic of virtual defecography technology in the etiological diagnosis of constipation. Methods 50 patients with constipation were included. Conventional clean- ing enema was performed firstly. Then they were injected the virtual defecography agentwith lateral position, filling the rectum, sigmoid and descending colon. Thirdly, siting on the qualities commode, adjusting height coincides with the left and fight femur, displaying the pubic symphysis and coccyx dynamic acquisition image acquisition with the speed of 4/s, the dynamic changes of the rectum and anal canal were analyzed and measured. Results Among 50 patients,32 cases with rectocele, 1 case with rectal bend,2 cases with anal canal stenosis ,7 cases with rectal prolapse,4 cases pel- vic floor spasm syndrome,and 4 cases with no cause. Conclusion Static and dynamic virtualdefecography was an im- portant method in the etiological diagnosis of patients with constipation.
