October 11th, 2009

   Gastroscopy - a procedure of examination of the esophagus, stomach and duodenum. It is performed by thin, flexible fiber-optic instrument that is introduced into the intestine through the mouth. This examination allows the doctor to detect damage to the inner lining of the esophagus or stomach, and gastric ulcer or duodenal ulcer.

The procedure is painless, but unpleasant enough; gastroscopy usually before the patient is given a mild sedative.

In some cases, do without sedatives - usually asks the patient not to give him drugs, as otherwise it all day will not be able to drive a car and do the job that requires high concentration of attention.

Furthermore, it is possible to record survey to further follow the changing condition of the patient.

Sometimes gastroscopy prescribed to patients who complain of symptoms similar to symptoms usually indigestion. Only in rare cases, these symptoms affect the cancer, but this possibility can not be ruled out. Thus, gastroscopy can also be used for the diagnosis of very dangerous diseases.

What can be seen with the help of gastroscopy

With gastroscopy possible to study in detail the inner surface of the body: the change in its topography, thickness and running folds mucosal vascular pattern and so on.

In the diagnosis of diseases of the stomach gastroscopy significantly superior to all other methods. It is the leading method in the detection of gastric cancer Stomach cancer: genetics and lifestyle  Stomach cancer: genetics and lifestyle
   in the early stages it is important in recognition of gastritis, erosions, ulcers and polyps, including those with very small dimensions and therefore is not visible on X-ray.

During the gastroscopy biopsy can - take a piece of tissue for research, take a picture of the inner surface of the test body. You can also hold a series of remedial measures: remove the foreign body, to remove small tumors and polyps, cauterize bleeding blood vessel (eg, gastric ulcer or duodenal ulcer 12), enter directly into the site of inflammation medication and so on.

Equipment gastroscopy

Gastroscope is a long, thin, flexible tube with a lens at one end. A detailed, clear images from the device is transmitted to the TV screen and can then be printed using the printer. Gastroscope may be under the control of, safely, to be held in the upper digestive tract, to carefully investigate its inner surface.

Modern gastroscopes have a small diameter, are well managed and have expressed flexibility. Optics they can be located on the side (gastroduodenoscopy) or end of the device (esophagogastroduodenoscopy).

Contraindications for gastroscopy are:

  • aneurysm (expansion rack to the wall thinning) of the aorta;
  • acute cerebrovascular (stroke) and coronary (myocardial infarction), blood circulation;
  • serechno severe diseases of the circulatory system, including severe stage of hypertension;
  • hemophilia (a bleeding disorder and a tendency to bleeding);
  • severe mental disorders;
  • a pronounced curvature of the spine;
  • frequently recurring attacks of asthma;
  • acute gastritis with frequent vomiting.

When using the gastroscope with side optics research is contraindicated in patients with diverticula (saccular protrusions of the wall), ulcers and varicose veins Varicose veins - the operation is inevitable?  Varicose veins - the operation is inevitable?

Relative contraindications to gastroscopy are the general poor health at the time of the study, advanced age, acute inflammation of the upper respiratory tract, hypertensive crisis Hypertensive crisis: how to protect themselves from the consequences of  Hypertensive crisis: how to protect themselves from the consequences of

How is a gastroscopy

Research is carried out strictly on an empty stomach (you can drink just a little plain water), the night before, at least for 10-12 hours prior to the procedure, let alone a light dinner. During the day, it is better not to smoke. The doctor must know what drugs a patient takes, and if he has an allergy.

Gastroscope is inserted through the mouth via a special nagubnik that keeps in the mouth the patient in the supine position on the left side, after local anesthesia of the pharynx (to remove the gag reflex). To ensure good visibility, the investigated cavity blown air. The whole procedure is painless.

After studies can not drink or eat for half an hour. After the capture of tissue for analysis (biopsy) was taken during the day the food should not be hot.

It is possible (but extremely rare) complications are perforation of the wall of the test body (perforation) and the bleeding resulting from damage to the blood vessel. Bleeding can be stopped during the study cauterizing the blood vessel perforation and require emergency surgery.

Gastroscopy - informative and relatively safe method of research, which in practice almost never gives complications.
