Can botulinum toxin help in managing children with functional constipation and obstructed defecation?

Background: Functional constipation (FC) is a common pediatric healthcare problem worldwide. Obstructed defection syndrome (ODS) is frequently presented with an inability to coordinate the bowel movement with pelvic floor muscles. Botulinum toxin (BT) intraanal sphincteric injection can improve the obstructed defecation by relaxing the anal sphincter and reducing the required force to propel the stools.
