Long-Term Functional Outcomes of an Anorectal Malformation French National Cohort.

Objectives: The present study aimed to assess long-term functional outcomes of children with anorectal malformations (ARMs) across a network of expert centers in France.

Methods: Retrospective cross-sectional study of patients ages 6-30 years that had been surgically treated for ARM. Patient and ARM characteristics (eg, level, surgical approach) and functional outcomes were assessed in the different age groups.

Results: Among 367 patients, there were 155 females (42.2%) and 212 males (57.8%), 188 (51.2%) cases with, and 179 (48.8%) higher forms without, perineal fistula. Univariate and multivariate statistical analyses with logistic regression showed correlation between the level of the rectal blind pouch and voluntary bowel movements (odds ratio [OR] = 1.84 [1.31-2.57], P < 0.001), or soiling (OR = 1.72 [1.31-2.25], P < 0.001), which was also associated with the inability to discriminate between stool and gas (OR = 2.45 [1.28-4.67], P = 0.007) and the presence of constipation (OR = 2.97 [1.74-5.08], P < 0.001). Risk factors for constipation were sacral abnormalities [OR = 2.26 [1.23-4.25], P = 0.01) and surgical procedures without an abdominal approach (OR = 2.98 [1.29-6.87], P = 0.01). Only the holding of voluntary bowel movements and soiling rates improved with age.

Conclusion: This cross-sectional study confirms a strong association between anatomical status and functional outcomes in patients surgically treated for ARM. It specifically highlights the need for long-term follow-up of all patients to help them with supportive care.
