Core Tip
Core tip: Submucosal tunnel endoscopy: Peroral endoscopic myotomy (POEM) and peroral endoscopic tumor resection (POET), constitutes a novel terrain for miniinvasive endoscopic treatment of diseases, where the surgical alternatives are totally incomparable, particularly in elderly. POEM showed exciting results in international level in treating all types of achalasia [classical (I), vigorous (II), spastic (III)], including advanced sigmoid type, failed surgical or laparoscopic Heller myotomy cases, and other esophageal motility disorders (diffuse esophageal spasm, nutcracker and jackhammer esophagus). POET was spawned from the success of POEM, and slowly expanded worldwide to treat muscularis based esophageal, esophagogastric junction and cardia submucosal tumors. Submucosal tunnel endoscopy further inspired other applications and opened promising future perspectives.
