<unk>  (EGJOO) is an esophageal motility disorder characterized by increased pressure where the esophagus connects to the stomach at the lower esophageal sphincter. EGJOO is diagnosed by esophageal manometry. However, EGJOO has a variety of etiologies; evaluating the cause of obstruction with additional testing, such as upper endoscopy, computed tomography (CT imaging), or endoscopic ultrasound may be necessary. When possible, treatment of EGJOO should be directed at the cause of obstruction. When no cause for obstruction is found <unk> al EGJOO), observation alone may be considered if symptoms are minimal.<unk> al EGJOO with significant or refractor symptoms may be treated with pneumatic dilation, per-oral endoscopic myotomy (POEM), or botulinum toxin injection.
