What is the difference FGS and EGD: differences, advantages, disadvantages
The spread of diseases of the upper gastrointestinal tract leads to frequent use of various diagnostic procedures in the population, the most important of which are EGD and FGS (fibrogastroscopy and fibrogastroduodenoscopy, respectively). Both methods differ from each other in methodology, which may require changes in the conditions of preparation of the patient, as well as affecting the indications and contraindications to the procedure. It is very important to understand the difference between FPS and very similar to EGD, in connection with their frequent use for the detection of pathology of the digestive system.
Description and distinguishing features of FGS from EGD
Any kind gastroscopy is the gold standard in detecting disease of the esophagus and stomach. This method of examination allows the doctor to view the condition of the inner lining of the digestive tract, to identify pathological changes, biopsy or small surgical operations. There are several varieties gastroscopy, between which there are small differences: fibrogastroscopy, or abbreviated as FGS, and fibrogastroduodenoscopy, or EGD.
- EGD fibrogastroduodenoscopy, or, is a diagnostic procedure used to identify diseases not only of the stomach but also the duodenum. In addition, using EGD, it is possible to estimate the ultimate divisions of the biliary ducts, which open onto the wall of the duodenum. Also, EGD is used for holding retrograde cholangiography and other procedures related to the study of the biliary system.
In this regard, the main difference between FGS from EGD is in the scope of the study: in the first case, the gastroscope is introduced only for the stomach, and the second to the duodenum, that allows to expand indications for the study.
Indications and contraindications to the use of techniques
The use of both diagnostic methods is strictly regulated by the indications and contraindications for. Indications for endoscopic examination are:
- Pain syndrome in a patient with localization of pain in the upper abdomen or lower thorax.
- Bloating and discomfort in the epigastric region.
- Dyspepsia in heartburn, nausea and vomiting.
- Sudden weight loss with preserved appetite.
- Suspected benign or malignant neoplasm.
- Bloody vomiting or other signs of blood loss (anemia, pallor, etc.).
As for the EGD, there are additional indications:
- Disruption of the biliary tract.
- Suspected ulcerative lesions of the duodenum.
- The need for retrograde cholangiography.
- Internal intestinal bleeding from the upper small intestine.
Contraindications to both procedures is identical:
- Decompensated diseases of the cardiovascular and respiratory systems.
- Of blood clotting.
- Ischemic heart disease with myocardial infarction, any stroke, etc.
- Mental sphere.
The observance of the indications and contraindications allows to enhance procedures and to reduce the risk of complications.
If the patient has contraindications detects, from the endoscopic methods of examination refused, preferring other methods of examining the gastrointestinal tract.
The choice of procedure should be performed only by the attending physician, after a full clinical examination of the patient and conducting other research methods.
The differences between FGS and EGD are enclosed in the method of the study. If the first option a doctor can view only the mucous membrane of the stomach, EGD can detect the disease and duodenal ulcer. The right choice of the examination procedure is of great importance for the correct diagnosis and assign rational treatment.
