- Abstract:
- Objective To explore the application value of distal pressure colostogram (DPCG) versus pelvic magnetic resonance imaging (MRI) in the diagnosis of congenital anorectal malformations (ARMs).Methods A retrospective analysis was performed for 83 ARM children before and after second-stage operation to clarify the accuracy and advantages of two imaging modes.Results Among them, 80 cases were diagnosed by MRI and clinical pathological type was consistent with the results of DPCG. Three cases showed merely the position of blind rectum and no abnormal fistula was detected. The distances between rectum and anal crypt as measured by MRI, DPCG and actually intraoperatively were (36.90±9.14), (36.39±10.81) and (34.40±12.70) mm respectively. There was no significant difference (P>0.05). MRI revealed tethered spinal cord (n=8), terminal filament steatosis (n=5), intrasacral lipoma (n=1), conical spinal cord hypoplasia (n=5), metatarsal tail dysplasia (n=3) and horseshoe kidneys (n=2), abnormal kidney development (n=3), ureteral dilatation (n=5), ureteral cyst (n=1), double uterine malformation (n=2) and Currarino syndrome (n=2).Conclusion Conclusion Both imaging studies can determine the location of blind rectum and abnormal fistulas. As compared with DPCG, MRI offers obvious diagnostic advantages of higher tissue resolutions, radiation non-exposure and bowel non-perforation.
