BACKGROUND: Endoscopic impedance planimetry (FLIP) has been used to evaluate the pyloric physiologic parameters after G-POEM for refractory gastroparesis; yet data on this technology is still limited…

BACKGROUND: Esophageal stenosis is a potential risk after endoscopic submucosal dissection (ESD), with incidence ranging from 70-90% among those with mucosal defects involving more than three-quarters of the circumference of the esophagus…

BACKGROUND: Esophageal epiphrenic diverticula (ED) are rare pulsion-type diverticulum in the distal esophagus that can develop in the setting of an underlying esophageal motility disorder as a result of the contractile dyscoordination between the distal esophagus and lower esophageal sphincter (LES…
