Not all patients with<unk> s have symptoms; barium swallow tests of the esophagus sometimes show<unk> s in patients with no swallowing difficulties. When<unk> s cause symptoms, they usually result in episodic difficulties with swallowing (dysphagia) solid foods, or a sensation that the food "sticks" while swallowing, especially if the food is not chewed thoroughly. Patients usually are able to regurgitate or force through the food material and resume eating. However, complete obstruction of the esophagus by a bolus of food (often called steakhouse syndrome) can occur. This can cause crushing chest pain and may need immediate treatment with endoscopy, which is the use of a specialized fibre-optic camera in order to remove the lodged food. After the obstruction is located, snares or forceps are inserted to pull the food out of the esophagus or to push it into the stomach. The latter is done with caution, usually when the anatomy of the structures around the obstruction is already known. Other associations *<unk> s can be associated with swallow syncope, a rare variety of syncope. *<unk> s are associated with lesser incidence of Barrett's esophagus, which is considered to be a pre-cancerous condition of the esophagus in some cases.
