In 54 children (50%) enterostomy was performed after birth. Nineteen of 26 children (73%) with a persisting growth problem had had an enterostomy, vs. 35/82 children (43%) without a persisting growth problem (p=0.007, Chi-Square test). Children with a persisting growth problem had a median (range) length of time with enterostomy of 529 (10 to 895) days vs. 470 (168 to 3622) days in the children without a persisting growth problem (p = 0.403, Mann–Whitney test). Seven of 25 children with spinal anomalies had scoliosis; in four of them the severity of scoliosis might have impaired growth.
The median (range) number of operations in children with a persisting growth problem was 8 (1 to 29), vs. 6 (0 to 29) in the children without a persisting growth problem (p=0.147, Mann–Whitney Test). Two of 9 children who underwent major cardiac surgery had a persisting growth problem. The median (range) number of operations related to the anorectal malformation in children with a persisting growth problem was 3 (0 to 6), vs. 1 (0 to 8) in the children without (p = 0.052, Mann–Whitney Test).
