Sa1315 EFFECTIVENESS AND SAFETY OF PER ORAL ENDOSCOPIC MYOTOMY IN ACALASIA COMPARING ANTERIOR AND POSTERIOR APPROACH IN A REFERENCE CENTER

Achalasia is an esophageal primary motor disorder, characterized manometrically by the incomplete relaxation of the lower esophageal sphincter and esophageal aperistalsis. Heller's myotomy is the gold standard therapie, but per oral endoscopic myotomy (POEM), with similar clinical and manometric success, is considered a safe alternative, the submucosal wall approach possible anterior or posterior esophagus depending on operator experience. As gastroesophageal reflux disease (GERD) is its main complication, there is few evidence about wich approach is safer and more effective.
