Prevalence, Risk Factors, and Prognosis of Postoperative Complications after Surgery for Hirschsprung Disease.

Background: Although most of patients do well after surgery for Hirschsprung disease (HSCR), there are complications in some instances that impact social aspects and quality of life. The aim of this study was to explore the prevalence, risk factors, and prognosis of these complications, providing guidance for surgeons and healthcare personnel.

Methods: A cohort of patients (N = 229) was retrospectively reviewed in the aftermath of surgery for HSCR. All medical data and operative notes were assessed. Early and late postoperative complications were solicited by questionnaire, using logistic regression and the Cox proportional hazards regression model for analysis.

Results: A total of 181 patients qualified for the study. Enterocolitis and soiling/incontinence constituted the most frequent complications, whether early or late in the postoperative period. Risk factors for developing enterocolitis included low weight, low-level IgA, preoperative enterocolitis, and lengthy aganglionic segment in the early term; whereas preoperative enterocolitis and diet control impacted complications emerging later. Risk factors in early soiling/incontinence were low weight, operative age of < 2 months, low IgA level, and lengthy aganglionic segment. Lengthy aganglionic segment, operative age of < 2 months, and toilet training were factors long-term. Prognostic factors included diet control and toilet training.

Conclusion: Enterocolitis and soiling/incontinence remain the most frequent complications after surgery for HSCR. Risk factors in early and late postoperative periods differed, with diet control and toilet training contributing favorably to enterocolitis and soiling/incontinence, respectively.
