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.

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.
