Botulinum toxin use in paediatric colorectal surgery.

Area of Science:

• Pediatric Gastroenterology
• Colorectal Surgery
• Pediatric Surgery

Background:

• Intractable constipation in children poses significant challenges.
• Intrasphincteric botulinum toxin injection (ISBTI) is a treatment option for refractory cases.
• Evaluating the efficacy and long-term outcomes of ISBTI in pediatric populations is crucial.

Purpose of the Study:

• To assess the functional outcomes of intrasphincteric botulinum toxin injection (ISBTI) in children with intractable constipation.
• To identify factors influencing the success rate of ISBTI in pediatric patients.
• To determine the need for subsequent interventions in non-responsive cases.

Main Methods:

• Retrospective review of pediatric patients (≤16 years) who underwent ISBTI between January 2010 and February 2014.
• Data collection included demographics, diagnoses, complications, follow-up duration, and functional outcomes.
• Statistical analysis was performed to correlate patient characteristics and treatment variables with successful outcomes.

Main Results:

• 72% of 43 pediatric patients reported symptom improvement after the initial ISBTI.
• Common diagnoses included idiopathic constipation (67%), Hirschsprung disease (26%), and anorectal malformation (5%).
• Symptom recurrence was observed in 39% at 12-month follow-up; 25% required further surgical management (e.g., antegrade continence enema or stoma).

Conclusions:

• ISBTI demonstrates a high initial success rate for pediatric intractable constipation.
• A significant proportion of patients may experience recurrence or require additional surgical interventions.
• Further research is needed to predict which children will benefit most from ISBTI.
