An esophageal food bolus obstruction is a medical emergency caused by the obstruction of the esophagus by an ingested foreign body.. It is usually associated with diseases that may narrow the lumen of the esophagus, such as eosinophilic esophagitis, Schatzki rings, peptic strictures, webs, or cancers of the esophagus; rarely it can be seen in disorders of the movement of the esophagus, such as ...
Esophageal rings and webs, are actual rings and webs of tissue that may occlude the esophageal lumen. Rings--- Also known as Schatzki rings from the discoverer, these rings are usually mucosal rings rather than muscular rings, and are located near the gastroesophageal junction at the squamo-columnar junction. Presence of multiple rings may ...
The narrowing is caused by a ring of mucosal tissue (which lines the esophagus) or muscular tissue. [1] A Schatzki ring is a specific type of "esophageal ring", and Schatzki rings are further subdivided into those above the esophagus/stomach junction (A rings), [2] and those found at the squamocolumnar junction in the lower esophagus (B rings ...
Dysphagia is distinguished from other symptoms including odynophagia, which is defined as painful swallowing, [8] and globus, which is the sensation of a lump in the throat. A person can have dysphagia without odynophagia (dysfunction without pain), odynophagia without dysphagia (pain without dysfunction) or both together.
It causes similar changes on endoscopy as eosinophilic esophagitis including esophageal rings, narrow-lumen esophagus, and linear furrows. Caustic esophagitis This occasionally occurs through occupational exposure (via breathing of fumes that mix into the saliva which is then swallowed) or through pica .
After about five months, though, the lump remained. That’s when he visited the doctor and underwent a scan to learn more about it. Hearing he had stage 4 cancer felt overwhelming.
Endoscopically, ridges, furrows, or rings may be seen in the esophageal wall. Sometimes, multiple rings may occur in the esophagus, leading to the term "corrugated esophagus" or "feline esophagus" due to the similarity of the rings to the cat esophagus. The presence of white exudates in the esophagus also suggests the diagnosis. [13]
