Prognostic factors of postoperative Hirschsprung-associated enterocolitis: a cohort study

Pediatr Surg Int. 2023 Jan 9;39(1):77. doi: 10.1007/s00383-023-05364-7.

ABSTRACT

PURPOSE: To identify prognostic factors of postoperative Hirschsprung-associated enterocolitis (HAEC).

METHOD: A retrospective cohort study of Hirschsprung patients between 2006 and 2021 was conducted. Patients with anorectal malformation and non-definitive surgery were excluded. Associated factors for postoperative HAEC were reported with hazard ratio (HR) and 95% confidence interval (CI).

RESULTS: Forty-nine patients were excluded due to concurrent anorectal malformation and incomplete data. Of 274 patients, 75 patients (27.4%) had at least one episode of postoperative HAEC. There were 28 patients (37.3%) who had multi-episodes of HAEC. The total episodes of post-operative HAEC in this study were 121 episodes (36.8%). In multivariable survival analysis, significant factors associated with postoperative HAEC were the aganglionic level above sigmoid colon (HR = 3.47, p = 0.023, 95% CI 1.19-10.09), and total colonic aganglionosis (HR = 14.83, p = 0.004, 95% CI 2.33-94.40). The patients who experienced clinical enterocolitis before 2 weeks after surgery significantly developed more postoperative HAEC (HR = 5.32, p = 0.038, % CI 1.09-25.92). The incidence of postoperative HAEC was increase in patients with postoperative obstructive symptoms (48.0%). One patient died due to severe sepsis from postoperative HAEC, while three others required intensive care.

CONCLUSIONS: The long involvement of aganglionic segment and early postoperative HAEC was significantly associated with postoperative HAEC. Frequent follow-up, parental education, and early treatment are recommended in these individuals, particularly in the first year after surgery.
