Botulinum Toxin A for the Treatment of Delayed Gastric Emptying

Abstract

Intrapyloric injection of botulinum toxin improves gastric emptying in patients with gastroparesis, although this benefit was not superior to placebo at 1 month. Also, in comparison to placebo, symptoms do not improve significantly by 1 month after injection. Overall, we are unable to recommend botulinum toxin therapy for widespread use in the treatment of delayed gastric emptying until more data are available.
