Introduction: Stasis from obstruction at the level of the internal anal sphincter (IAS) can lead to Hirschsprung-associated enterocolitis (HAEC) and may be improved by botulinum toxin (BT) injections. Our aim was to determine if BT injection during HAEC episodes decreased the number of recurrent HAEC episodes and/or increased the interval between readmissions.
Methods: A retrospective review was performed of patients admitted for HAEC from January 2010 to December 2019. Demographics and outcomes of patients who received BT were compared to patients who did not receive BT during their hospital stay.
Results: A total of 120 episodes of HAEC occurred in 40 patients; 30 patients (75%) were male, 7 (18%) had Trisomy 21 and 10 (25%) had long-segment disease. On multivariate analysis, patients who received BT during their inpatient HAEC episode had a longer median time between readmissions (p = 0.04) and trending toward an association with fewer readmissions prior to a follow-up clinic visit (p = 0.08).
Conclusion: The use of BT in HD patients hospitalized for HAEC is associated with an increased time between recurrent HAEC episodes and trended toward fewer recurrent episodes. The use of BT should be considered in the management of patients admitted with HAEC.

Article Synopsis
- A study was conducted to create a clinical prediction model for determining the risk of postoperative Hirschsprung-associated enterocolitis (HAEC) within 5 years following surgery in children with Hirschsprung disease.
- The research included 274 patients, revealing that 27.4% experienced HAEC, with eight significant predictors identified, like gender, weight at surgery, and the type of surgical approach.
- The prediction model demonstrated promising accuracy (AuROC of 0.749) and established risk categories (low and high), aiding in patient management and follow-up; an online tool was also developed for calculating individual risk.
Clinical characteristics and influence of postoperative Hirschsprung-associated enterocolitis: retrospective study at a tertiary children's hospital.

Purpose: To explore the influence of postoperative Hirschsprung-associated enterocolitis (post-HAEC) on long-term outcomes and to identify risk factors of post-HAEC.
Methods: The medical records of 304 eligible patients diagnosed with Hirschsprung's disease (HSCR) were reviewed. We analyzed the clinical characteristics of post-HAEC and its influence on long-term outcomes.

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.

Background: Hirschsprung-associated enterocolitis (HAEC) is the most common cause of morbidity and mortality amongst patients with Hirschsprung disease (HD); rectal Botulinum toxin (Botox) has been reported a possible prevention strategy. We aimed to evaluate our institution's historic cohort of HD patients, first to determine our incidence of HAEC and second to begin assessing the effect of Botox on HAEC incidence.
Methods: Patients with HD seen at our institution between 2005 and 2019 were reviewed.
