Long-term impact of fistula status on growth and anemia in infants with congenital anorectal malformations

Background and Objectives: To evaluate the impacts of fistula status over 12 months on growth and development and anemia in infants with anorectal malformation (ARM) and to analyze the effects of comorbidities. Methods and Study Design: The ARM group included infants who suffered from ARM and underwent three operations including colostomy, anoplasty (group A) and fistula closure (group B). The normal group included infants aged approximately 6 months and 12 months who were classified as groups C and D. A 24-h dietary recall questionnaire was completed by the guardians of all the participants. Data on height, weight, hemoglobin (Hb) level and comorbidities were extracted from electronic medical records. Then, we compared the impacts of the 12-month fistula status on growth and development and anemia among the infants. Results: In total, 47 patients in the ARM group and 100 infants in the normal group were included. The height-for-age z-score (HAZ) was lower in group A than in group B. Compared with those in group D, weight, height, the HAZ and the weight-forage z-score (WAZ) were lower in group B. The incidence of anemia was higher in the ARM group than in the normal group. Conclusions: Patients with ARM are at risk for growth problems and anemia. The long-term impacts of fistula status on infant length presented earlier than those associated with other physical indicators. Compared to infants with urogenital comorbidities, those with congenital heart disease (CHD) seemed to be more prone to growth disorders and anemia.
