Evaluation of Post-neonatal Intensive Care Unit Home Irrigations Prior to Pull-through: Implications for Hirschsprung Disease Management

Abstract

Background: Pull-through procedures for Hirschsprung disease (HD) can be performed during the Neonatal Intensive Care Unit (NICU) stay or delayed until discharge following home irrigations. This study assesses the safety of a delayed pull-through as an alternative to neonatal reconstruction in infants with successful abdomen decompression with home irrigations based on Hirschsprung-associated enterocolitis (HAEC) development.

Methods: A single-institution retrospective review of neonates with HD who underwent delayed or neonatal pull-through from July 2018-July 2022. Endpoints included post-pull-through HAEC incidence, recurrence at an 18-month follow-up, time to the first HAEC episode, NICU length of stay (LOS), and HAEC-related LOS.

Results: Twenty-four neonates were included. Eighteen were discharged from the NICU with home irrigations. Of these, 3 (28%) developed enterocolitis preoperatively, 12 (67%) underwent a delayed pull-through. NICU LOS in the delayed cohort was 3 times shorter than in the neonatal (6 vs. 18 days, p < 0.01). The incidence of enterocolitis (82% vs. 80%), time to the first episode (43 vs. 57 days), and HAEC-related LOS (median of 3 days) were similar.

Conclusions: Delayed HD pull-through is a viable neonatal reconstruction alternative that reduces NICU stay without increasing the risk of postoperative HAEC development.
