title: Fluoroscopic findings post-peroral esophageal myotomy.
abstract: Natural orifice transluminal endoscopic surgery (NOTES) is a surgical technique that has been evolving rapidly. Endoscopic submucosal dissection was initiated in 1999, in Japan, for en-bloc resection of large lesions of the stomach (Zhou et al., World J Gastroenterol 19:6962-6968, 2013, ; Kobara et al., Clin Exp Gastroenterol 7:67-74, 2014). Since then, many additional therapies utilizing natural transluminal endoscopic approach have evolved. Peroral endoscopic myotomy (POEM) is a minimally invasive type of transluminal endoscopic surgery that was recently developed for the treatment of achalasia and esophageal motility disorders. The peroral endoscopic myotomy is a less invasive surgical treatment that is suitable for all types of achalasia and used as an alternate to the Heller myotomy. The radiographic findings of achalasia and surgical changes after Heller myotomy have been described, however, very little is available on the post-POEM esophagram appearance. The purpose of this article is to illustrate the anatomy, surgical procedure, and normal and abnormal findings seen on esophagrams in patients who have undergone a POEM.
