BackgroundTrisomy 13 (T13), trisomy 18 (T18), and trisomy 21 (T21) are the most common autosomal trisomies. One unifying feature of all trisomies is their association with major congenital malformations, which often require life-prolonging surgical procedures. Few studies, mostly among cardiac surgery patients, have examined the outcome of those who undergo surgical procedures. We examined the differences in postsurgical outcomes between the trisomy groups.MethodUsing the National Surgical Quality Improvement Program dataset, we identified children (<18 years of age) with T13, T18, or T21 who underwent noncardiac surgery (2012-2018). We estimated the incidence of mortality and indicator of resource utilization (unplanned reoperation, unplanned tracheal reintubation, and extended length of hospital stay).ResultsOf the 349 158 inpatient surgical cases during the study period, we identified 4202 children with one of the autosomal trisomies of interest (T13: 152; T18: 335; and T21: 3715). The rates of postoperative mortality were substantially higher for T18 and T13 than T21 and nontrisomy children (T18 vs. T21: 11.1% vs. 1.6%, adjusted odds ratio: 5.01, 95%CI: 2.89,8.70, p < .01), (T13 vs. T21: 8.1% vs. 1.6%, adjusted odds ratio: 2.86, 95%CI: 1.25,6.54, p = .01). Children with T18 had the highest rates of extended length of stay (62.7%) and prolonged mechanical ventilation (32.5%). T18 and T13 neonates had the highest surgical mortality burden (T13: 26.5%, T18: 31.8%, and T21: 2.8%).ConclusionApproximately, one-third of T18 and T13 neonates, who had surgery, died, underscoring the lethality of these trisomies and the need for a comprehensive preoperative ethical discussion with families of these children.© 2022 John Wiley & Sons Ltd.
