Hirschsprung's disease associated enterocolitis: A comprehensive review.

Area of Science:

• Pediatric Surgery
• Gastroenterology
• Developmental Biology

Background:

• Hirschsprung's disease (HSCR) is a congenital condition caused by the failure of neural crest cell migration, resulting in distal bowel obstruction.
• Hirschsprung's disease associated enterocolitis (HAEC) is a severe complication of HSCR, increasing patient morbidity and mortality.
• The exact causes of HAEC are not fully understood, but factors like gut dysmotility, microbial imbalance, and weakened gut barrier function are implicated.

Purpose of the Study:

• To provide a comprehensive review of Hirschsprung's disease associated enterocolitis (HAEC).
• To elucidate the clinical presentation, etiology, and pathophysiology of HAEC.
• To summarize current therapeutic strategies for managing HAEC.

Main Methods:

• Literature review of clinical presentations, etiological factors, and pathophysiological mechanisms of HAEC.
• Analysis of diagnostic criteria and treatment guidelines for HAEC.
• Synthesis of current research on therapeutic options for HAEC.

Main Results:

• HAEC presents as an inflammatory complication of HSCR, occurring pre- or postoperatively.
• Key contributing factors to HAEC pathogenesis include intestinal dysmotility, dysbiosis, and impaired mucosal defense.
• Diagnosis of HAEC is primarily clinical, with treatment tailored to disease severity.

Conclusions:

• HAEC is a significant clinical challenge in HSCR management.
• Further research into the pathophysiology of HAEC is crucial for developing targeted therapies.
• A standardized definition and improved treatment protocols for HAEC are needed.
