%X <B>OBJECTIVE: </B>To explore the influence of postoperative Hirschsprung-associated enterocolitis (post-HAEC) on long-term outcomes and to identify risk factors of post-HAEC.<BR><B>METHODS: </B>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. Furthermore, risk factors for early and recurrent HAEC were identified separately.<BR><B>RESULTS: </B>The overall incidence of post-HAEC was 29.9% (91/304). We categorized early HAEC as occurring within postoperative 3 months (n = 39) and recurrent HAEC as occurring ≥ 3 episodes within postoperative 6 months (n = 25). Patients with early HAEC were more likely to experience worse nutritional status, defecation function, and quality of life compared to those with late or no episodes (P < 0.05). Similarly, the adverse influences of recurrent HAEC on these outcomes were also significant (P < 0.05). The risk factors for early HAEC included preoperative undernutrition, long-segment HSCR, and postoperative Grade 3-4 complications within 30 days. For recurrent HAEC, risk factors were preoperative malnutrition, non-parental caregivers, long-segment HSCR, and postoperative Grade 3-4 complications within 30 days.<BR><B>CONCLUSIONS: </B>Classification of post-HAEC based on the first episode time and frequency was necessary. The earlier or more frequent episodes of post-HAEC have detrimental influences on long-term outcomes. Furthermore, risk factors for early and recurrent HAEC were different.
