Gastroscopy (endoscopy) and how to prepare for it

The purpose of endoscopy is a detailed inspection of the mucosa of the upper digestive system, which is made by endoscopic examination. We are talking about the esophagus, the stomach and the adjoining segment of the duodenum.

To do this, use with small diameter flexible endoscope that is inserted through the mouth and passes through the esophagus.

The need for examination of the stomach occurs in various situations. One of the primary research is esophagogastroduodenoscopy, abbreviated to EGD. What is a esophagogastroduodenoscopy and how to prepare for the procedure below the first time to get effective results?

Why the need for gastroscopy?

The preparation of the study endoscopy may be required in the following situations:

The main benefit of endoscopy of the stomach compared to traditional chest x-ray is increased several times the accuracy of detecting inflammatory changes of the mucosa, emerging or resistant ulcers. If preparing for esophagogastroduodenoscopy is associated with suspected cancer, in addition to visual inspection of the mucous membranes, be sure to do a biopsy, allows to Refine or refute the diagnosis. Tissue for biopsy is taken by means of a special tool, any unpleasant feelings do not exist.

Also during endoscopy there is the possibility of removing polyps, retrieving, accidentally swallowed foreign bodies, stop minor bleeding, allowing you to exclude open abdominal surgery. Sometimes the procedure becomes an extension of the narrowed area of the esophagus or stomach or to take the material that doing the test for the presence of Helicobacter pylori bacteria that trigger the disease of the gastrointestinal tract.

Recommended procedure?

Among the indications for EGD are:

  1. 1. Differential diagnosis of pathologies of the digestive system. We are talking about peptic ulcer, gastritis, diverticulitis, pyloric stenosis and other disorders.
  2. 2. Monitoring of the treatment of diseases of the gastrointestinal tract.
  3. 3. The necessity of dynamic observation of patients suffering from chronic pathologies of the gastrointestinal tract.
  4. 4. Symptoms suggestive for thinking about internal bleeding.
  5. 5. The postoperative treatment of the esophagus, stomach or duodenum. Qualitative studies are planned and carefully conducted procedure allow early diagnosis of complications and to identify pathological changes of the mucosa.

1. The day before endoscopy.

If the day of the scheduled examination, the night before dinner should take place no later than 8 PM. While the menu may contain only light foods that will not hinder digestion. After dinner, you can’t consume dairy products.

If training prior to the study EGD was performed according to the recommendations, you can count on maximum reliability and informativeness of this method. Upon detection of the inflammatory process in the stomach, or foreign entities of the mucous membrane, make additional analyses and examinations that the total picture was very clear. A gastroscopy is necessary to consult the doctor-gastroenterologist, which will determine the tactics of diagnosis and therapy.
