Barrett's esophagus is a condition in which there is an abnormal (metaplastic) change in the mucosal cells lining the lower portion of the esophagus, from stratified squamous epithelium to simple columnar epithelium with interspersed goblet cells that are normally present only in the small intestine and large intestine.
Rings cause intermittent mechanical dysphagia, meaning patients will usually present with transient discomfort and regurgitation while swallowing solids and then liquids, depending on the constriction of the ring. Webs--- Usually squamous mucosal protrusion into the esophageal lumen, especially anterior cervical esophagus behind the cricoid ...
Although H. pylori infection can cause gastrointestinal metaplasia, its eradication does not reverse the process. [1] Bile reflux is an additional pathogenic factor in gastrointestinal metaplasia that can continuously irritate the gastric mucosa. Bile acids in refluxed fluid are widely reported to be associated with gastrointesinal metaplasia ...
Cameron lesions are usually found in older adults with anemia symptoms such as fatigue, shortness of breath, and appearing pale. Blood tests in iron deficiency show low hemoglobin, microcytic hypochromic red cells, and low iron-binding saturation and ferritin levels. The lesions are visualized by esophagogastroduodenoscopy.
GERD sometimes causes injury to the esophagus. These injuries may include one or more of the following: Reflux esophagitis – inflammation of esophageal epithelium which can cause ulcers near the junction of the stomach and esophagus [19] Esophageal strictures – the persistent narrowing of the esophagus caused by reflux-induced inflammation
People with Barrett's esophagus (a change in the cells lining the lower esophagus) are at much higher risk, [55] and may receive regular endoscopic screening for the early signs of cancer. [56] Because the benefit of screening for adenocarcinoma in people without symptoms is unclear, [2] it is not recommended in the United States. [1]
uncertain; adults 0.1%, as high as 8.5% in children Lymphocytic esophagitis is a rare and poorly understood medical disorder involving inflammation in the esophagus . The disease is named from the primary inflammatory process, wherein lymphocytes are seen within the esophageal mucosa.
Megaesophagus may be caused by any disease which causes the muscles of the esophagus to fail to properly propel food and liquid from the mouth into the stomach (that is, a failure of peristalsis). Food can become lodged in the flaccid esophagus, where it may decay, be regurgitated, or maybe inhaled into the lungs (leading to aspiration ...
