摘要
目的 利用核素排便造影的方法探讨先天性无肛畸形患儿排便功能的改变。方法 对4 3例无肛畸形患儿和 11例正常儿进行核素排便造影检查 ,分析患儿组反映直肠肛管综合控制能力、排便功能和耻骨直肠肌功能的客观指标变化。结果 正常儿直肠肛管保留率为 (92 .5± 3.3) % ,而无肛畸形患儿临床评分优组为 (80 .5 1± 9.6 7) % ,临床评分劣组为 (5 1.14± 6 .90 ) % ,均明显低于正常组(P <0 .0 5 )。合并术后便秘的患儿组的残留率明显增大 ,排空率明显降低 ,半排时间明显延长 ,统计学分析 ,差异有显著性意义。结论 核素排便造影方法是评价肛门直肠功能和排便功能的重要客观检测方法 ,无肛畸形患儿的肛门直肠和排便均有不同程度的改变。
Objective To study the loss of normal defecation in children with anorectal malformation by isotope defecography.Methods Forty three patients with anorectal malformation and 11 normal children were subjected to isotope defecography and radiocinematographic defecography.Results The anorectal control rates and anorectal angle under the different status of the patients were significantly decreased. In cases with postoperative constipation, the half defecation times were prolonged, the evacuation rates were decreased and the residual rates increased significantly.Conclusions The isotope defecography can be used to evaluate anorectal function and ability of defecation comprehensively and dynamically. Patients with anorectal malformation suffer from various loss of anorectal function and abnormal defecation.
