Patient-reported outcomes of Children with an Anorectal Malformation

We aimed to study the impact of anorectal malformation (ARM) type and sacral ratio on continence outcomes in children. We secondarily aimed to compare continence outcomes by age group and determine quality of life (QoL) with different bowel regimens. Children with ARM experience dysfunctional stooling into adulthood. Little is known about how ARM type, sacral ratio, age, and bowel regimen affect continence and QoL. We administered five validated survey measures on stooling habits and QoL to children aged 2-19 with ARM at two tertiary hospitals. Sacral ratio as a determinant of sacral hypodevelopment was defined as normal (≥0.7), moderate (0.4-0.0.69), or severe (≤0.39). Children not on an enema program were compared to those on an enema program to identify factors associated with achieving voluntary bowel movements defined as continence. All children were compared to identify factors associated with QoL. Of 910 patients, half (52.8%) had mild sacral hypodevelopment. In patients not receiving enemas managed solely at study hospitals, most were continent (69.2%). There were no differences in continence demonstrated by sacral ratio; 79.4% of those who were continent had normal/moderate sacral hypodevelopment and mild ARM.Continence improved with age (50% ≤6 y old, 69.8% 6-12 y old, 82.1% >12 y old; P
