POEM for Spastic Esophageal Disorders
POEM for Spastic Esophageal Disorders
This study evaluates the efficacy and safety of the Per-Oral Endoscopic Myotomy (POEM)
 technique for lower esophageal sphincter myotomy in patients suffering from spastic
 esophageal disorders such as achalasia at a Canadian institution.

 The investigators hypothesize that POEM is a safe and effective technique for the surgical
 management of such disorders at our institution.
Standard surgical care for spastic esophageal disorders such as achalasia includes a
 procedure called Heller myotomy.

 The treatment in our study, called endoscopic myotomy (also known as peroral endoscopic
 myotomy - POEM) is different from standard surgery (Heller myotomy) because it is less
 invasive, is less likely to cause reflux, and usually requires shorter operative times with
 less loss of blood during the surgery. Although POEM has been adopted worldwide and has
 proven to be successful, the experience in Canada is very limited to date.
