Differences endoscopy and EGD
Diseases of the gastrointestinal tract always similar symptoms, so sometimes the only way to put a definite diagnosis of the disease of these bodies is to conduct researches of their mucous membrane. Informative are methods esophagogastroduodenoscopy and EGD. They are similar, but there are also characteristic differences.
What is EGD and EGD? The first abbreviation stands for fibrogastroduodenoscopy, and EGD is esophagogastroduodenoscopy.
Description of the research
What is the difference between the above studies? The main characteristic difference is the volume of the investigated organs. Namely, when EGD examined the stomach and duodenum, and with endoscopy to assess the condition of the mucous membrane of the esophagus. This is indicated by the titles of these studies. The word «fibrogastroduodenoscopy» is made up of several parts, which in Latin mean:
- Fibro is the name of the flexible probe of the fiberscope;
- Gastro – stomach;
- Duodeno is the duodenum;
- Scopy – examination with a visual assessment of the mucosa.
Esophagogastroduodenoscopy also composed of several parts. Namely, the added part «of the esophago», which means the esophagus, and then all consistently.
Both of these methods patients referred to simply as a gastroscopy.
In conducting both of these studies, the gastroscope is inserted through the mouth. He then enters the esophagus, etc., the Patient swallows the tube and the endoscopist starts the study. As at the end of the tube is a tiny video camera and light source.
Most unpleasant for the patient point is the ingestion of gastroscope, further, the endoscopist can adjust the depth of occurrence of the probe. In order to reduce the discomfort the patient is instructed to rinse or spray the throat with special substance anesthetic. Lasts 15 minutes. This is more than enough for diagnostic examination. If you require any manipulation surgery, the procedure time increases to 30 minutes.
Endoscopy is able to identify a number of pathologies of the upper gastrointestinal tract. And, in the course of the procedure can be performed and surgical intervention on the esophagus, of the stomach and duodenum.
Esophagogastroduodenoscopy EGD is different from that in time this procedure can be used to diagnose cancer lesions, varicose veins of the esophagus and stenosis. The physician in this case assesses the change in its mucous membrane. If it is visible swelling and redness, then this is evidence of superficial esophagitis. Atrophic esophagitis manifests other changes – too mucous thinned and has a pale hue.
Esophagogastroduodenoscopy EGD is different from the fact that it is possible to diagnose the presence of the diverticulum, that is, the protrusion of the walls of the esophagus. This procedure will help to distinguish these growing in the lumen of education from cancer.
At EFGDS you can still apply medicines for burns of the mucous membrane of the esophagus. Pathology of the stomach and duodenum can be viewed at EGD. Among them are gastritis, peptic ulcer disease, gastrointestinal bleed localization, etc.
With EGD and EGD can consider the stomach. With the help of the gastroscope can determine the areas where the mucous membrane is thinned, and when gently pressing on them can manifest bleeding. This may indicate the presence of a tumor. A tumor that grows into the lumen of the stomach will be visible visually.
FGS determines the quality of the stomach contents. When this is diagnosed duodenogastric reflux, is a condition in which the bile overflows into the stomach. As well as the endoscopist can see the blood there.
During the inspection of the stomach evaluated the motility of the stomach, namely the waves and their direction. It is also important to assess the condition of the pyloric sphincter. Normally it is closed, and if it is open, then it indicates a neoplastic process in his region.
The duodenum can be viewed using EGD and EGD. This estimated state of the mucosa in the area of bulbous and nalukolongo space. Visually will be visible ulcers, erosions, thickening and swelling of the mucous membrane.
In both procedures provide therapeutic intervention. Namely, to stop bleeding with the help of the gastroscope improve the clip or ligature tamponade. Also hold:
- Biopsy, i.e. the collection of material for histological examination.
- Removal of polyps.
- Expand the area of the esophagus affected by stenosis – this procedure is called probing.
- The fence of material for research on helicobacteria.
- The application of the drug in the pathological area. For example, the performance of a chemical coagulation of the vessel. In the case of endoscopy it can be done in the esophagus.
It is important that when EGD and EGD can see and diagnose the presence of benign and malignant neoplasms.
It should be noted that endoscopy is performed in the case of frequent heartburn, regurgitation and difficult swallowing, and with pain in the region of the esophagus. Additionally, EGD, and EGD is prescribed for the presence of pain in the stomach and abdomen, with frequent nausea and vomiting.
Preparation for procedures
What is the difference in preparation for these studies? Preparation for endoscopy and EGD are the same, no differences there. This is due to the fact that are these studies the same pattern. Therefore, the patient should follow a special diet for 2-3 days. The main rules are the use of liquid or well-chopped food, also the products should be easily digestible. Exclude fat and fried foods. All recommendations for this issue gives the attending physician that directs to this diagnosis.
Sometimes patients are prescribed medications that promote rapid digestion as the stomach must be empty. Otherwise, throughout the procedure, possible gag reflex with the release of vomiting.
EGD and EGD, differences on the list of contraindications are not. Contraindications:
- Excessive bleeding gastric localization.
- When hypertensive crisis is also not carried out these studies.
- Cardiovascular complications such as stroke, heart attack, aneurysm, etc.
- Complicated by bronchial asthma.
- A state of shock, coma.
A conditional contraindication are mental disorders, neuroses and psychoses. Usually such patients prescribed EGD or endoscopy under anesthesia.
