Objective: 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.
Summary background data: 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.
Methods: 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.
Results: 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<0.001). Those on enemas and soiling had a QoL 19.6 points lower than those soiling on laxatives, and 20.7 points lower than those who were clean on enemas or continent with voluntary bowel movements without the need for enemas.
Conclusions: In patients on laxatives the type of malformation, but not sacral ratio, is associated with continence in patients with ARM. Continence improves with age; those on enemas with soiling have a worse QoL.
Intended audience: Healthcare professionals and clinicians.
You have a patient with an anal rectal malformation. Are you using the sacral ratio to counsel them? I'm Jill Knetreth with Stay Current MD, and this is an article you should know about. In 2024, what at All. with Nationwide Children's published a survey in the Annals of Surgery that looked at over 900 patients with anal rectal malformation. Authors found that found that improved. Importantly, they found that there was actually there was no difference incontinence for patients for patients on sacral ratio ratio alone in regards to quality of quality of life. Patients who are incontinent incontinence had a 20/20 quality of quality of life compared to patients who were continent incontinent or clean or clean on enemas. So what's the takeaways the takeaway here when it comes to when it comes to patients rectal rectal malformation, the sacral ratio ratio may not be as predictor of continence as we as we age and bowel may actually matter more. Additionally, quality of quality of life significant for patients incontinence enemas. Does this change this change your practice?
