How do gastroscopy (EGD) stomach?
Among the numerous methods of research of organs of the gastrointestinal tract endoscopy is the most informative. Gastroscopy of the stomach and its advanced equivalent – fibroesophagogastroduodenoscopy (fegds) allow you to inspect not only the mucous membrane of the stomach and the condition of the walls of the esophagus, the initial division of the duodenum. This procedure is tolerated by all the different. But at the present stage of adequate preparation and use of thin probes makes the manipulation even more painless. The article focuses on how do gastroscopy and preparation, indications and contraindications to it.
When shown the study?
To do a gastroscopy everyone the patient is impractical. What is a gastroscopy and how it will affect the body as a whole? It was a kind of risk for the patient. What can be dangerous this procedure?
Another bonus gastroscopy – study of the acid function, which is important in the pathology of the gastrointestinal tract.
In the appointment procedure is important to help understand the patient, what is EGD and how you do it.
Preparation for the procedure
For quality and informative result of the EGD is necessary first of all to explain to the patient the nature of the investigation. In medical institutions give information consent forms that patients fill out and sign. The doctor explains the need for gastroscopy, its risks, possible, complications. The next phase is to talk about how to make EGD. You can use the pictorial brochures or videos, making of gastroscopy, and how is the preparation for it.
Usually, fegds is conducted in the morning.
For Breakfast the patient ban. Even water intake should be limited to the extent necessary only for zapivaniya drugs. The method of fegds involves the interruption of the use of certain medications. That is the best time to study without medication. This is especially true:
- preparations of bismuth;
- antisecretory drugs (Omez, Razo);
- antacids: gaviscon, Maalox, Almagel.
At least 3-4 days these drugs should be abolished.
It’s more complicated with the abolition of the medicines used to treat arrhythmias and hypertension or other systemic diseases. About how to act in each specific situation, should consult a cardiologist or neurologist depending on concomitant pathology.
12 hours before you perform faggs, you need last make a light dinner. Otherwise there is a possibility that the results will be skewed or will appear copious vomiting (reflex).
The training includes a talk about that Smoking the day before and the day of the procedure is strictly prohibited. Nicotine stimulates the production of mucus, hydrochloric acid. This will distort the endoscopic picture of the mucous membrane of the esophagus, stomach or duodenum.
The description of the course of study
How do next after the preparation of the gastroscopy of the esophagus, stomach and duodenum? The patient may need to anesthetize the oral cavity. For this purpose, suitable local anesthetics. Normally this is Lidocaine. But first you need to find out the presence of allergic reactions in the anamnesis of these drugs, to avoid its development during fegds.
Mouth pay attention to the presence of dentures. If necessary, they are better off. Next, the posterior wall of the mucosa of the oropharynx irrigate with a solution of anaesthetic substance. It is not so much for pain as for eliminating the gag reflex. After all, the gastroscope will pass into the cavity of the stomach through the mouth.
Next, the algorithm (method of conduct) provides as follows:
- The correct position of subjects. The patient lay on the couch. He takes position on the left side so that the pillow appeared to be the area of the left cheek. Recommend hands to cross on chest. It facilitates the procedures (better pass the probe).
- In the oral cavity includes the mouthpiece is made of plastic. Explain to the patient that it is necessary to clamp with his teeth and tightly clenching lips. This mouthpiece plays the role of a fuse. It is quite possible that the probe, which has already passed through the mouth can be bitten off.
- In the region of the tongue root should be extremely cautious. Despite the fact that an anesthetic substance anaesthetises the region of the oropharynx, until the end of the possibility of implementing the gag reflex is not excluded.
- At last the retching is possible to advance the probe. The breathing should be deep, infrequent. This allows you to avoid vomiting.
- The doctor then gently lead the probe with the endoscope and inspecting the condition of the mucous membrane of the esophagus first, then the stomach, then in the duodenal bulb.
The whole procedure not usually takes more than an hour.
If similar studies were conducted earlier, it simplifies the procedure. After all, the endoscopist can rely on the results of the previous faggs, and the emphasis put on then the identified «problem» areas.
After completion of the exam, the doctor may do a biopsy. Taken mucosa are sent to the pathology lab for histological examination. This is important for the diagnosis of precancerous and other developmental processes.
Instead of a conclusion
Fibroesophagogastroduodenoscopy in modern conditions necessary for the diagnosis of various forms of gastritis, ulcerative lesions of the stomach and duodenum. Special category States represent erosion of the digestive tract. Due to an increase in the proportion of persons resorting to frequent use of nonsteroidal anti-inflammatory drugs.
It should be noted that, faggs important not only for diagnosis. This method is applicable for monitoring the effectiveness of treatment. There is also the possibility to remove a polyp or other lesions and to take biopsy.
The frequency of this procedure depends on what was revealed. If the process of dysplasia or metaplasia, monitor the condition of the mucous membrane of the stomach or esophagus to 2-3 times per year to prevent development of malignant tumors. If acid situations EGD is performed according to the clinical manifestations (at deterioration).
