Hirschsprung disease in Down syndrome: An opportunity for improvement

Background: Down syndrome (DS) is the most common abnormality associated with Hirschsprung dis-ease (HD). It has been suggested patients with HD and DS have worse outcomes, however the literature is controversial. Methods: The Kids' Inpatient Database (KID) from 2003 to 2012 was used to identify newborns with HD. Demographics, hospital characteristics, and outcomes were compared among patients with and without DS using standard statistical tests. Results: There were 481 patients identified with HD, of which 45 (9%) had DS. Patients with DS were older at the time of first rectal biopsy (6 [3-11] days vs. 4 [3-6] days, p = 0.012). There were no dif-ferences in operative versus non-operative management in patients with and without DS ( p = 0.706). Hospital length of stay was longer in the DS cohort (22 [13-33] days vs. 15 [10-24] days, p = 0.019), and patients with DS were more likely to have a concomitant diagnosis of wound infection ( < 12% vs. 3%, p = 0.002) and necrotizing enterocolitis ( < 14% vs. 5%, p = 0.018). The mortality rate for patients with DS was four times higher than those without DS (< 5% vs. < 0.8%, p = 0.018). Conclusion: In this nationwide cohort of patients with Hirschsprung disease, those with Down syndrome experienced delays in diagnosis and worse outcomes. Level of evidence: Level III. Type of study: Treatment study, retrospective comparative study.(c) 2022 Elsevier Inc. All rights reserved.

Automated summary

This study analyzed the clinical characteristics and outcomes of patients with Down syndrome and Hirschsprung disease. The results showed that patients with Down syndrome experienced delays in diagnosis, longer hospital stays for surgical patients, and a higher mortality rate.
