EGD - esophagogastroduodenoscopy

EGD (Esophagogastroduodenoscopy):

EGD, also known as Esophagogastroduodenoscopy, is a procedure used to examine the inside of the esophagus, stomach, and the first part of the small intestine, called the duodenum. This procedure is commonly done with the help of a thin flexible tube that is inserted into the mouth and through the esophagus. This instrument is called an endoscope, which is advanced into the upper digestive tract.

Preparation:

For an EGD, the patient usually has to fast for eight to 12 hours prior to the procedure, and patients are typically asked to stop eating and drinking two to three hours before the procedure. The patient may be asked to take some laxatives and enemas prior to the procedure.

Procedure:

The patient is usually placed in a left lateral position, and the doctor starts the procedure by passing the endoscope through the mouth and throat and advancing it into the esophagus. The doctor inspects the esophagus through the endoscope and then passes it into the stomach. The endoscope is then moved to the duodenum to make a complete inspection.

Types of EGD:

• Diagnostic EGD – This type of EGD is done when the doctor suspects any disorder or diseases in the digestive system.
• Therapeutic EGD – This type of EGD is done when the doctor needs to take samples for testing or to perform a biopsy.

Risks:

EGD usually has few risks and complications. However, the most common risks include bleeding, reaction to the sedatives, and perforation of esophageal tissue due to the endoscope. The patient may also experience some discomfort or pain during the procedure.

Why is EGD done:

Esophagogastroduodenoscopy is used for the early diagnosis, as well as to monitor the progress of any digestive diseases, such as GERD (Gastroesophageal Reflux Disease), stomach ulcers, Crohn’s disease, and celiac disease. In addition, EGD is used to evaluate any abnormalities in the digestive system and to take samples for pathology.

When is an EGD done:

An EGD may be done when the patient has symptoms such as abdominal pain, nausea, vomiting, heartburn, and difficulty swallowing. It is also done if the patient has been diagnosed with a digestive disorder, such as GERD, or abnormal growths in the upper digestive system. EGD is also used to evaluate any abnormalities found during an upper endoscopy or abdominal X-ray or CT scan.
