Botox Injection (Anal Sphincter and Pyloric Sphincters) :: Nationwide Children's Hospital

Botox® Injection of Anal Sphincter

Botox® is the brand name of a toxin produced by the bacterium Clostridium botulinum (botulinum toxin). When a small amount is injected into a muscle, it causes the muscle to relax. Your child’s doctor may recommend Botox® injection of the anal sphincter under selected circumstances, such as when the child is having difficulty with stooling specifically because of problems with relaxation of the muscles that make up the anal sphincter. The injection is done while the child is asleep under anesthesia. The effect on the muscle is not permanent but can last for many weeks to months.
