Endoscopic image of a Schatzki ring which is a common cause of<unk> <unk><unk><unk>  is most commonly caused by Schatzki rings, which are mucosal rings of unknown cause in the lower esophagus.<unk> stuff jams into the esophagus due to the narrowing caused by the ring. An increasingly commonly recognized cause for<unk>  is eosinophilic esophagitis, which is an inflammatory disorder of the mucosa of the esophagus, of unknown cause. Many alterations caused by eosinophilic esophagitis can predispose to<unk><unk> es; these include the presence of multiple rings and narrowing of the lumen. When considering esophageal dilation to treat a patient with<unk><unk><unk> , care must be made to look for features of eosinophilic esophagitis, as these patients are at a higher risk of dilation-associated complications. Other conditions that predispose to<unk><unk><unk> s are esophageal webs, tracheoesophageal fistula/esophageal atresia (TOF/OA) and peptic strictures.<unk><unk> es are common in the course of illness in patients with esophageal cancer but are more difficult to treat as endoscopy to push the<unk>  is less safe. Patients with esophageal self-expandable metallic stents may present with<unk><unk> es lodged within the stent lumen. Rarely disorders of movement of the esophagus, such as nutcracker esophagus, can predispose to<unk><unk><unk> .
