Insights
VACTERL associations are common in children with esophageal atresia/tracheoesophageal fistula (EA/TEF) and anorectal malformation (ARM). Cardiac issues are more frequent with EA/TEF, while spinal and renal anomalies are more common with ARM.
Area of Science:
- Pediatric Surgery
- Medical Genetics
- Developmental Biology
Background:
- VACTERL (Vertebral, Anal, Cardiac, Tracheo-Esophageal, Renal, Limb) anomalies represent a complex spectrum of congenital malformations.
- Understanding the co-occurrence patterns of these anomalies is crucial for comprehensive patient management and genetic counseling.
Purpose of the Study:
- To compare the incidence and types of VACTERL associations in pediatric patients undergoing surgery for esophageal atresia/tracheoesophageal fistula (EA/TEF) versus anorectal malformation (ARM).
Main Methods:
- Utilized the Pediatric Health Information System (PHIS) database from 2004-2012, encompassing data from 43 children's hospitals.
- Identified and cross-referenced surgical records for EA/TEF and/or ARM with diagnoses of vertebral, cardiac, renal, and limb anomalies.
- Analyzed records for children meeting criteria for VACTERL diagnosis (3 or more associated anomalies).
Main Results:
- In 2689 EA/TEF repairs, VACTERL associations included: 25.5% vertebral, 11.6% ARM, 59.1% cardiac, 21.8% renal, and 7.1% limb defects. 33.4% met VACTERL criteria.
- In 4962 ARM repairs, VACTERL associations included: 31.5% vertebral, 40.4% cardiac, 7.0% EA/TEF, 34.7% renal, and 7.2% limb defects. 36.2% met VACTERL criteria.
- Significant differences in anomaly clusters were observed between the two groups.
Conclusions:
- VACTERL associations are prevalent in both EA/TEF and ARM patient cohorts.
- Congenital heart disease is a more frequent co-occurrence in EA/TEF, whereas vertebral and renal/urinary anomalies are more common in ARM.
- These findings highlight distinct patterns of VACTERL component associations based on the primary congenital anomaly.
Purpose:
The aim of this study was to compare the frequency and nature of VACTERL associations between children who underwent surgery for esophageal atresia/tracheoesophageal fistula (EA/TEF) and anorectal malformation (ARM).
Methods:
We identified all children who underwent surgery for EA/TEF and/or ARM at hospitals participating in the Pediatric Health Information System (PHIS) database between 2004 and 2012. PHIS is an administrative database of free-standing children's hospitals managed by the Child Health Corporation of America (Overland Park, KS) that contains patient-level care data from 43 hospitals. The complete records of patients in this cohort were cross-referenced for diagnoses of vertebral, cardiac, renal and limb anomalies.
Results:
2689 children underwent repair of esophageal atresia. Mean gestational age was 36.5±3.2weeks and mean birth weight was 2536.0±758.7g. Associated VACTERL diagnoses included vertebral anomaly in 686 (25.5%), ARM in 312 (11.6%), congenital heart disease in 1588 (59.1%), renal disease in 587 (21.8%) and limb defect in 192 (7.1%). 899 (33.4%) had 3 or more anomalies and met criteria for a VACTERL diagnosis. 4962 children underwent repair of ARM. Mean gestational age was 37.4±2.7weeks and mean birth weight was 2895.2±765.1g. Associated VACTERL diagnoses included vertebral anomaly in 1562 (31.5%), congenital heart disease in 2007 (40.4%), EA/TEF in 348 (7.0%), renal disease in 1723 (34.7%) and limb defect in 359 (7.2%). 1795 (36.2%) had 3 or more anomalies and met criteria for a VACTERL diagnosis.
Conclusion:
VACTERL associations are relatively common in children with EA/TEF and ARM and occur in specific clusters, with cardiac disease more common in EA/TEF and spinal and renal/urinary anomalies more common in ARM.
