- Radiofrequency Ablation Treatment for Barrett's Esophagus. Radiofrequency Ablation (RFA) is an FDA-approved endoscopic technique used by specialists at the Massachusetts General Hospital Barrett’s Esophagus Treatment Center to treat Barrett’s esophagus.

Achalasia Achalasia can be diagnosed by X-ray, endoscopy, or esophageal manometry. Treatments for achalasia include oral medications, dilation or stretching of the esophagus, surgery, and. injection of muscle-relaxing medicines (botulinum toxin) directly into the esophagus. There is no specific diet to treat achalasia.

Radiofrequency ablation Radiofrequency ablation (RFA) is a medical procedure in which part of the electrical conduction system of the heart, tumor or other dysfunctional tissue is ablated using the heat generated from medium frequency alternating current (in the range of 350–500 kHz).

Esophageal atresia Congenital esophageal atresia (EA) represents a failure of the esophagus to develop as a continuous passage. Instead, it ends as a blind pouch. Tracheoesophageal fistula (TEF) represents an abnormal opening between the trachea and esophagus.

- Figure 1. Location of the esophagus in the body. Barrett's Esophagus: Introduction Barrett's esophagus is a condition in which columnar cells replace the usual squamous cell in the mucosa of theesophagus.The condition is recognized as a complication of gastroesophageal reflux disease.arrett's Esophagus: Anatomy The esophagus serves as a conduit between the pharynx and the stomach. The body of the esophagus is approximately 18–25 cm in length extending from the upperesophageal sphincter (C5-C6 vertebral space) to the lower esophageal sphincter (T10 level).

Esophagus The esophagus (American English) or oesophagus (British English), commonly known as the foodpipe or gullet, is an organ in vertebrates which consists of a fibromuscular tube through which food passes, aided by peristaltic contractions, from the pharynx to the stomach.he esophagus may be affected by gastric reflux, cancer, prominent dilated blood vessels called varices that can bleed heavily, tears, constrictions, and disorders of motility. Clinical investigations include X-rays using barium, endoscopy, and CT scans.

Tracheoesophageal fistula Tracheoesophageal fistula. A tracheoesophageal fistula (TEF, or TOF; see spelling differences) is an abnormal connection (fistula) between the esophagus and the trachea. TEF is a common congenital abnormality, but when occurring late in life is usually the sequela of surgical procedures such as a laryngectomy.

- Megaesophagus, also known as ME, is a condition in humans, cats, dogs and horses where peristalsis fails to occur properly and the esophagus is enlarged. Normally, when the animal's esophagus is functioning properly, it acts as a muscle and pushes the food down the esophagus into the stomach. However, when an animal has megaesophagus, the esophagus stays enlarged and does not push the food down to the stomach. Therefore, the food fails to enter the stomach and often stays in the esophagus, and is eventually regurgitated, or enters the lungs through breathing, or decays in the esophagus. In human pathology a condition known as achalasia may predispose a person to slowly develop megaesophagus.

- Currently, RFA is a standard treatment for patients with inoperable liver tumors. It is being increasingly used for other cancers, such as lung cancers, kidney (renal), and certain benign and malignant bone tumors, and is being tested for other types of cancer.

Barrett's Esophagus: More Patients? Barrett's esophagus is the leading cause of esophageal cancer, which is one of the fastest growing cancers in the U.S. The condition causes symptoms such as heartburn and waking during the night due to heartburn pain and acid regurgitation.

- Esophageal cancer. Overview. Esophagus The esophagus is a muscular tube that connects your mouth and your stomach. Rings of muscle (sphincters) in the upper and lower portions contract and relax to allow food and liquid to pass. Esophageal cancer Esophageal cancer occurs in the cells that line the inside of the esophagus.

Stomach 1 The esophagus connects to the stomach at a small region called the cardia. 2  The cardia is a narrow, tube-like region that opens up into the wider regions of the stomach. 3  Within the cardia is the lower esophageal sphincter, a band of muscle tissue that contracts to hold food and acid inside of the stomach. Within the cardia is the lower esophageal sphincter, a band of muscle tissue that contracts to hold food and acid inside of the stomach. 2  The cardia empties into the body of the stomach, which forms the central and largest region of the stomach. 3  Superior to the body is a dome shaped region known as the fundus.

Esophageal Diverticula An esophageal diverticulum is a pouch, or pocket, of stretched tissue that develops anywhere along the esophagus, pushing outward through its muscular wall. They are rare, and can be congenital or acquired. Typically a single pouch forms, most often near the top of the esophagus; this is called Zenker’s diverticulum. In other cases, a pouch forms nearer to the bottom of the esophagus (epiphrenic) or, less frequently, in the middle. A single diverticulum ranges from 1 to 4 inches in diameter.

Radiation Esophagitis Radiation esophagitis if often described as a “sunburn on the inside of the esophagus.” The esophagus it the long swallowing tube that sits in the middle of the chest usually right next to the trachea (the windpipe). The tube connects the mouth to the stomach.

Vital capacity Output of a spirometer. Vital capacity is the maximum amount of air a person can expel from the lungs after a maximum inhalation. It is equal to the sum of inspiratory reserve volume, tidal volume, and expiratory reserve volume. A person's vital capacity can be measured by a wet or regular spirometer.urthermore, the vital capacity is used to determine the severity of respiratory muscle involvement in neuromuscular disease, and can guide treatment decisions in Guillain-Barre barré syndrome and myasthenic. Crisis a normal adult has a vital capacity between 3 and 5. litres

Barrett's Esophagus: Symptoms, Causes, and Treatments Barrett's esophagus is a serious complication of GERD, which stands for gastroesophageal reflux disease. In Barrett's esophagus, normal tissue lining the esophagus-- the tube that carries food from the mouth to the stomach-- changes to tissue that resembles the lining of the intestine.

Why Persistent Acid Reflux Sometimes Turns Into Cancer: New Clues Adenocarcinoma of the esophagus, the cancer that is especially associated with Barrett's esophagus, is currently the most rapidly rising cancer in the U.S., with a sixfold increase in cases during the past 30 years, according to the National Cancer Institute.

Our Innovative VOAT Procedure Established Technology. Radiofrequency ablation (RFA) is a procedure where tissue is removed using the heat generated from the high frequency alternating current to treat a medical disorder.The current is produced by a radio wave and is used to heat a small area of nerve tissue to decrease pain signals from that area.nbelievable Results. With the AAOC’s patent pending VOAT™ procedure, 80% of Dr. Dillard’s patients see an improvement in their condition. In addition, the minimally invasive procedure can take as little as 30 seconds with some slight sedation.

Esophageal Atresia Esophageal atresia is the abnormal development of the swallowing tube (esophagus) that connects the mouth to the stomach. This birth defect results in the incomplete connection of the esophagus to the stomach causing an inability to swallow properly and breathing difficulties.

Radiofrequency ablation RFA is generally conducted in the outpatient setting, using either local anesthetics or conscious sedation anesthesia. When it is delivered via catheter, it is called radiofrequency catheter ablation.

Esophageal atresia Esophageal atresia. Esophageal atresia (or Oesophageal atresia) is a congenital medical condition (birth defect) that affects the alimentary tract. It causes the esophagus to end in a blind-ended pouch rather than connecting normally to the stomach.

Achalasia Without a modifier, achalasia usually refers to achalasia of the esophagus, which is also called esophageal achalasia, achalasia cardiae, cardiospasm, and esophageal aperistalsis. Achalasia can happen at various points along the gastrointestinal tract; achalasia of the rectum, for instance, in Hirschsprung's disease.
