Abstract

Background and Study Aims: In patients with esophageal achalasia, pneumatic dilation is the treatment of choice, but it bears the risk of perforation in about 4 % of cases. A new nonsurgical method, intrasphincteric injection of botulinum toxin A, has shown promising initial results, and we thus undertook this study to compare the long-term outcome of these two methods.
