839 significant reduction of post-operative gastroesophageal reflux development by the posterior myotomy using two penetrating vessels (tpvs) in peroral endoscopic myotomy (poem)

Peroral endoscopic myotomy (POEM) is an evolving new treatment strategy for achalasia. To date, a number of studies have demonstrated that POEM can achieve excellent clinical outcomes. However, one of the concerns related to POEM is gastroesophageal reflux (GER) after treatment. The myotomy positions are generally placed at 2 or 5 o ’clock position. Although, the 5 o’clock position (posterior approach) allows better scope maneuverability as the working channel is located over 5-7-o’clock position in most endoscopes, it theoretically has a risk to partially damage oblique muscle, which may increase the frequency of post-PO EM GER.
