Objective To compare diagnostic accuracy between MRI and X-ray distal colosto-gram in patients with congenital anorectal malformations(CARM)combined with fistulae.Meth-ods 29 children who underwent colostomy and treatment of anorectal malformation phase Ⅰ fis-tula in Jiangxi Provincial Children's Hospital were selected for the study.MRI and X-ray distal colostogram were performed on all the children to analyze rectal morphology,the presence or ab-sence of fistulae,and the types of fistulae.The diagnostic accuracy of the two examinations for fis-tulae in children with CARM were analyzed and compared.Results All 29 children with CARM after colostomy had fistulae on intraoperative exploration.From MRI distal colostogram,fistulae,the alignment of fistulae and the type of fistulae were seen in 26 cases;in 3 cases,fistulae were not seen(cloacal malformation in 2 cases and rectovaginal fistula in 1 case).From X-ray distal co-lostogram,fistulas were seen in 24 cases and they were not seen in 5 cases;among the 5 unseen fistulas,3 cases were urethro-prostatic fistulae and 2 cases were rectourethral bulbous fistulas,all showing bird's beak-like changes in the distal part of the rectum.The X-ray diagnostic accuracy for CARM fistula was 82.75％(24/29),and the MR1 diagnostic accuracy was 89.7％(26/29).The differences were not statistically significant(x2=0.706,P＞0.353).Conclusion MRI distal colos-togram can reveal rectal morphology,fistula opening,and type of fistulae without radioactive damage,similar to the results of X-ray colostogram,and it can provide more detailed anorectal anatomy for the selection of clinical surgery.
