Double peroral endoscopic myotomy for achalasia
As experience grows with peroral endoscopic myotomy (POEM), operators are taking on more anatomically challenging cases. Additionally, we are now seeing patients who relapse after a prior POEM. Therefore, the operator must be aware of the steps necessary to adequately investigate and treat such patients. For example, it is of no benefit to continue to target the lower esophageal sphincter if this already has been treated effectively. We herein present 2 different teaching cases in which 2 POEM procedures (double POEM) were performed in each of the patients (Video 1, available online at www.giejournal.org ).Submucosal tunneling endoscopic resection of a giant esophageal leiomyoma
Submucosal tunneling endoscopic resection (STER) for removal of upper GI tumors arising from the muscularis propria (MP) has been demonstrated to be effective and safe. In this video, we demonstrate the feasibility of STER for a giant, symptomatic esophageal leiomyoma and the closure of a large mucosal entry. A 53-year-old woman was seen with a 2-month history of progressive dysphagia and chest pain. A chest CT scan revealed a 6 × 2.8 × 2.2-cm esophageal mass adjacent to the descending aorta and azygos vein (Fig. 1; Video 1, available online at www.giejournal.org ).
