Spinal dysraphism as a new entity in V.A.C.TE.R.L syndrome, resulting in a novel acronym V.A.C.TE.R.L.S

Anorectal malformation (ARM) is the most common symptom in VACTERL syndrome (vertebral, anal, cardiac, tracheo-esophageal fistula, renal, and limb anomalies). The association of ARM and spinal dysraphisms (DYS) is well documented. We aim to better evaluate children with VACTERL association and ARM, considering the presence or not of DYS. Between 2000 and 2015, 279 children with VACTERL associations were identified in Necker Children’s Hospital, Paris. We identified 61 VACTERL children (22%) with ARM. A total of 52 VACTERL children with ARM were included. DYS were identified in 36/52 of cases (69.2%). A total of 33 (63.5%) VACTERL children presented with sphincterial dysfunction. We constated that 28/33 (84.8%) of them had DYS + (p < 0.0001). More children in ARM (DYS +) subgroup are presenting with initial urinary sphincter dysfunction (58 vs 19%, p < 0.009) than ARM (DYS -). We identified 29 lipoma filum in our series, which were not statistically associated with urinary disorders (p = 0.143).

Conclusion: We propose to refine the definition of VACTERL association, by adding S as Spinal defect to include it as an integral part of this syndrome, resulting in a novel acronym V.A.C.TE.R.L.S.
