DDW

Digestive Disease Week

The largest international gathering of physicians, researchers and academics in the fields of gastroenterology, hepatology, endoscopy and gastrointestinal surgery. Jointly sponsored by the American Association for the Study of Liver Diseases (AASLD), the American Gastroenterological Association (AGA) Institute, the American Society for Gastrointestinal Endoscopy (ASGE) and the Society for Surgery of the Alimentary Tract (SSAT). The meeting showcases more than 5,000 abstracts and hundreds of lectures on the latest advances in GI research, medicine and technology. www.ddw.org

DMS

DeMeester Score

Uses parameters such as total reflux and number of episodes to numerically measure esophageal acidity and assess the severity of gastroesophageal reflux disease (GERD). It is most commonly used to document the severity of GERD, with a score >14.72 representing reflux considered significant.

EAE

esophageal acid exposure

EAE, if abnormal, is used to objectively document GERD. Abnormal EAE is often determined by either 48-h wireless pH BRAVO or 24-h ambulatory pH testing while off PPI therapy for at least seven days. If determined by the 24-h test, the normal value is usually considered to be <4.5% (% total time pH <4). If determined by 48-h pH BRAVO, the normal value is ≤ 5.3% (% total time pH < 4).

EAC

Its mission is to save lives by increasing awareness about the link between Heartburn and Cancer, promoting early detection and supporting medical innovation to prevent, detect and treat Esophageal Cancer. www.ECAN.org

EGD

Involves insertion of an endoscope through the mouth and throat into the esophagus and stomach (often while the patient is sedated) in order to assess the internal surfaces of the esophagus, stomach, and duodenum.

EGJ

Esophagogastric Junction (also called cardia)

Anatomical term for the junction orifice of the stomach and the esophagus. At this level, the mucosa of the esophagus transitions into gastric mucosa.

ELF

Endo Luminal Fundoplication

The first technical description and preliminary version of the TIF procedure

ENT

Ear, Nose Throat

A type of surgeon in the field of otolaryngology, the study of diseases in the ear canals and upper airway. Some atypical GERD symptoms that ENTs sometimes see first are hoarseness, throat clearing, cough, sore throat, dysphagia, or globus.

FLIP

Functional Lumen Imaging Probe

Created by McMahon et al to measure cross-sectional sectional areas of the esophagus at extremely small intervals.

GEJ

Gastroesophageal Junction

see EGJ

GERD

Gastroesophageal Reflux Disease

A chronic condition in which acid from the stomach flows back into the lower esophagus, causing pain or tissue damage; also known as acid reflux.

GSRS

Gastrointestinal Symptom Rating Scale

Scale used to diagnose the severity of gastrointestinal symptoms and to determine treatment for patients suffering from such symptoms. The GSRS contains five scales: reflux syndrome, abdominal pain, constipation syndrome, diarrhea syndrome and indigestion syndrome.

GERSS

Gastroesophageal Reflux Symptom Score

Assess heartburn, regurgitation, bloating, and dysphagia and epigastric/retrosternal pain (Anvari 2006). The total scale ranges from 0 to 60 where a “well-controlled” score is defined as < 18.

GEV

Gastroesophageal Valve

The 3 - 4 cm musculo-mucosal fold created through the oblique Angle of His at which the esophagus enters the stomach. This flap valve opens only for swallowing and closes promptly. When competent and fully intact, prevents the reflux of gastric contents up into the esophagus.

GI

Gastroenterologist

Gastroenterology

a type of physician practicing in the field of gastroenterology,the study of the digestive system and digestive diseases

H2 blocker

also called H2RA

Histamine type-2 receptor antagonist (stomach acid)

Drugs that prevent or block the production of gastric acid. A pump in the stomach releases hydrochloric acid when stimulated by histamine. H2 blockers prevent histamine from stimulating this pump, thereby reducing the amount of acid that is released into the stomach. H2 blockers are available over-the-counter (OTC) or by prescription [e.g. Cimetidine (Tagamet), Famotidine (Pepcid), Ranitidine (Zantac)].

HH

Hiatal Hernia

Protrusion (or herniation) of the upper part of the stomach into the thorax through a tear or weakness in the diaphragm.

HPZ

High Pressure Zone

Detected manometrically—is the lower end of the esophagus does not have a true anatomic sphincter.

HRM

High Resolution Manometry

Gastrointestinal motility diagnostic system that measures intraluminal pressure activity in the gastrointestinal tract using a series of closely spaced pressure sensors.

HRQL

Health Related Quality of Life

Validated survey to quantify the subjectivity of patient symptoms to identify GERD.

LA Grade

Los Angeles Grade

scale used to classify severity of esophagitis (inflammation of the esophagus)

LES

Lower Esophageal Sphincter

A ring of smooth muscle fibers at the junction of the esophagus and stomach; also called cardiac sphincter, gastroesophageal sphincter.

LF

Laparoscopic Fundoplication

Procedure that involves wrapping the fundus 360° around the surgically mobilized distal esophagus using a less invasive approach.

LERD

Laryngopharyngeal Esophageal Reflux Disease

Proximal gastroesophageal reflux affecting the upper esophagus and airway with concomitant ENT symptoms or signs such as hoarseness, throat clearing, cough, sore throat, dysphagia, or globus.

LPR

Laryngopharyngeal Reflux Proximal

see LERD

MII

Multi-Channel Intraluminal Impedance

High resolution manometry—may be combined with manometry or pH studies to examine patient symptoms to a higher degree of specificity. MII-pH augments current esophageal pH monitoring by detecting non-acid reflux and weakly acidic reflux (pH exposure ≥ 4) in patients with atypical symptoms or in patients who continue to experience typical symptoms despite use of medical therapy.

NERD

Non-Erosive Reflux Disease

One of many types of GERD characterized as reflux disease without esophagitis, i.e. without the slow erosion of the lining of the esophagus.

pH

 A 0-14 scale measuring acidity (0) to neutral (7) to alkalinity (14) and for GERD patients, used in determining the level of stomach acidity and percentage of time the esophagus is exposed to stomach acid.

pH-metry

pH manometry

see MMI

PPI

Proton Pump Inhibitors

Drugs that reduce the production of acid by blocking the enzyme in the wall of the stomach that produces acid. The reduction of acid prevents ulcers and allows any ulcers that exist in the esophagus, stomach and duodenum to heal. Examples: Omeprazole (Prilosec), Iansoprazole (Prevacid), Esomeprazole (Nexium).

RDQ

Reflux Disease Questionnaire

Validated survey to quantify the subjectivity of patient atypical symptoms to identify GERD.

RESPECT

TIF

Transoral Incisionless Fundoplication

Minimally invasive (no cutting) procedure that reconstructs the GEV from inside the stomach by forming a ~270 degree wrap using the EsophyX® device under direct visualization by an endoscope.

UES

Upper Esophageal Sphincter

Natural resistance area located in cervical esophagus consisting of cricopharyngeus and inferior pharyngeal constrictor muscles.

UGI

Upper Gastrointestinal series

A radiologic examination of the upper gastrointestinal tract.

Z-line

Zigzag line

The squamocolumnar junction where the lining changes from white esophageal (squamous) tissue to red gastric (columnar) tissue. The line is irregular hence the name Z (zigzag) line. The lower esophageal sphincter is located in this area. (Ok not an acronym but cool info just the same.)
