Balloon-based radiofrequency ablation, invented by Ganz, Stern, and Zelickson in 1999, is a new treatment modality for the treatment of Barrett's esophagus and dysplasia and has been the subject of numerous published clinical trials.
Plummer–Vinson syndrome (also known as Paterson–Kelly syndrome [1] or Paterson–Brown-Kelly syndrome in the UK [2]) is a rare disease characterized by dysphagia (difficulty swallowing), iron-deficiency anemia, glossitis (inflammation of the tongue), cheilosis (cracking at the corners of the mouth), and esophageal webs (thin membranes in the esophagus that can cause obstruction). [1]
It is characterized by the signs and symptoms of intestinal obstruction without any lesion in the intestinal lumen. [1] Clinical features mimic those seen with mechanical intestinal obstructions and can include abdominal pain , nausea , abdominal distension , vomiting , dysphagia and constipation [ 2 ] [ 3 ] depending upon the part of the ...
Some people also experience a sensation known as globus esophagus, where it feels as if a ball is lodged in the lower part of the esophagus. The following are additional diseases and conditions that affect the esophagus: Achalasia [1] Acute esophageal necrosis; Barrett's esophagus; Boerhaave syndrome; Caustic injury to the esophagus; Chagas disease
Some physicians advocate either once-in-a-lifetime or 5- to 10-yearly endoscopy for people with longstanding GERD, to evaluate the possible presence of dysplasia or Barrett's esophagus. [45] Biopsies performed during gastroscopy may show: Edema and basal hyperplasia (nonspecific inflammatory changes) Lymphocytic inflammation (nonspecific)
Adenocarcinoma is the most prevalent in the US and is associated with patients with chronic GERD who have developed Barrett's esophagus (intestinal metaplasia of esophageal mucosa). Squamous cell carcinoma is more prevalent in Asia and is associated with tobacco smoking and alcohol use.
Barrett's esophagus is the dominant pre-malignant lesion of esophageal adenocarcinoma, [18] and has prevalent epigenetic alterations. [ 19 ] Esophageal squamous-cell carcinomas may occur as second primary tumors associated with head and neck cancer , due to field cancerization (i.e. a regional reaction to long-term carcinogenic exposure).
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]
