Botulinum toxin A (BOTOX) is a powerful inhibitor of muscle contraction. BOTOX can be injected through an endoscope to relax muscles in the GI tract, including the lower esophageal sphincter (end of the esophagus) in achalasia, and the pylorus (end of the stomach) in patients with gastroparesis. This procedure adds negligible additional risk to standard endoscopy and is used only under certain circumstances. Ask your physician if BOTOX injection is right for you.
