摘要目的用手术结果为参考标准来比较高分辨力MRI和经结肠造瘘口加压造影在患有肛门直肠畸形新生儿术前诊断的价值。方法共选择33例(22例为男性)有肛门直肠畸形的新生儿。所有病人术前均行高分辨力MRI检查(未使用镇静剂和对比剂)和经结肠造瘘口加压造影。用Krickenbeck标准对肛门直肠畸形进行分类,并评估了直肠盲端水平与肛提肌的关系。结果研究对象包括9例球部尿道直肠瘘,6例前列腺直肠尿道瘘,5例前庭瘘,5例泄殖腔
Abstract Objective To compare the value of high resolution MRI and colostomy pressure before angiography in preoperative diagnosis of anorectal malformation with the surgical results as a reference standard. Methods A total of 33 newborns with anorectal malformations were selected from 33 patients (22 males). All patients underwent high-resolution MRI (without sedatives and contrast agents) and colostomy pressure contrast. The Krickenbeck criteria was used to classify the anorectal malformations and assess the relationship between the level of the rectum blindness and levator ani. Results The study included 9 cases of urethral rectal fistula, 6 cases of prostate rectal urethral fistula, 5 cases of vestibular fistula, 5 cases of cloaca
