Hirschsprung disease associated enterocolitis: a systematic review and meta-analysis

Introduction: Hirschsprungs disease-associated enterocolitis (HAEC) remains a substantial morbidity and mortality risk in Hirschsprung's disease. HAEC is a challenge. Its p athophysiology is still a mystery, and no adequate treatment strategy exists. The aim of the study is to analyse the pre-and post-operative, mortality and complications: strictures, anastomotic leak, constipation and incontinence associated with HAEC. Materials and Methods: Adjust to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) 2020; this study met all the requirements and was up-to-date. The search approach was online publications between 2013 and 2023 in Pubmed and SagePub. It was decided not to consider review pieces that had already been published and half done. The STATA 18th version was used for meta-analysis. Results: Our search results included 370 PubMed and 149 SagePub articles. Since 2013, 134 PubMed and nine SagePub articles have been obtained, and seven studies have met the criteria. Conclusion: Disorders of intestinal motility in the aganglionic segment and accumulation of faeces disrupt the balanced microbiota population, which are factors of pre-operative HAEC. Major congenital anomalies and low birth weight worsen pre-operative HAEC. Pre-operative HAEC can continue and affect the post-operative. Constipation and fecal incontinence are still the main challenges after HSCR surgery. © 2024 Elsevier B.V., All rights reserved.
