First described in Japan in 2008, & then first performed in the United States in 2009, the POEM procedure (peroral endoscopic myotomy) is a 'miminally invasive' approach to replace the Heller myotomy for achalasia & other related disorders, where conservative management has failed or is not indicated.  A form of NOTES, the POEM is performed via endoscopic access to the gastroesophageal junction, via a submucosal tunnel approach, which allows rapid secure closure with clips placed at the mucosotomy site.  POEM is now used at multiple centers with similar outcomes to date as with surgical myotomy.   The purpose of this exhibit is therefore to review the world-wide experience, as well as our extensive institutional experience; to demonstrate the expected and unexpected imaging findings following POEM; to explain the procedure and its indications and contra-indications; & to review the relevant current clinical and limited imaging literature. 

- Indications, contra-indications, and current status/role of POEM - What the endoscopist needs to know from the radiologist before and after the POEM procedure - Expected and unexpected imaging findings before and after the procedure (radiography, fluoroscopy, & CT) - Outcomes/review of the literature - Early and late potential adverse events: recognition & management
