EGD and gastric biopsy - can see at first with the help of optical equipment changes in the wall of the stomach, and then confirm the presumptive diagnosis data taken by histological examination of biopsy tissue.With EGD can identify severe diseases of the stomach and duodenum in the early stages.
What EGD and its species
EGD (fibrogastroduodenoscopy) - a method of endoscopic examination of the stomach (gastritis) and duodenum (duodeno) using a flexible optical instrument - fibrescope (fiber).In practice, often carried out simultaneous study of the esophagus, stomach and duodenum, which is called esophagogastroduodenoscopy (EGD).
Modern gastroscopes are optical devices of high accuracy.They allow you to see the displayed monitor and if necessary enlarged image of the walls of the esophagus, stomach and duodenum.
EGD can be diagnostic and therapeutic.Upon detection of pathologies during diagnostic EGD can be using special tools to take a piece of tissue for histological examination, smea
Sometimes during the diagnostic study patient requires emergency assistance (for example, bleeding, removing a foreign body, and so on).In this case, using special tools for visual inspection (all manipulations are carried on the monitor) conducted emergency surgery.
During EGD therapy can be carried out as small elective surgery and manipulation: removing polyps stomach, administered directly into the stomach or the duodenum drugs, for example, promotes healing of gastric ulcers stomach ulcer - snacks such dangerous or duodenum.
This is shown holding EGD and contraindications for its implementation
Diagnostic EGD carried out at all diseases of the stomach and duodenum.Typically, in the same study turn on esophageal disease.In most cases EGD coupled with biopsy allows the final diagnosis.
Emergency medical EGD performed to eliminate bleeding from the upper gastrointestinal tract, the removal of foreign bodies.Routine endoscopic surgery can remove polyps and small benign tumors of the stomach.When handling routine in the stomach or duodenum administered drugs without allowing drugs to break down in the environment unsuitable for them.
EGD is contraindicated in sharp narrowing of the esophagus (eg, after a chemical burn) - this can cause rupture of the esophageal wall.
a relative contraindication is the general plight of the patient at a variety of diseases.But for health reasons (for example, gastric bleeding) relative contraindications are not considered.
Evaluation EGD and biopsy
During the EGD can be identified: partial patency of the upper gastrointestinal tract, the presence of the restrictions, scarring, impaired functioning of the cardiac esophageal sphincter (the muscle that prevents the ingress of gastric contents into the esophagus)changes in the mucous membrane of the stomach and duodenum (the inflammatory, metabolic and degenerative nature of atypical epithelial areas, and so on), the presence of reflux (reverse throwing food masses) from the stomach into the esophagus from the stomach into the duodenum, chronic gastritis Gastritis - severalstomach disorders and his views, gastric ulcer and duodenal ulcers, hiatal hernia, diverticula (bulging muscle wall), polyps, benign and malignant tumors.
Often during EGD biopsy is taken by a piece of tissue for histological examination.The resulting material is sent to a laboratory for microscopic histological study, which holds the doctor-pathologist.During the study, tissue cells taken determines whether among the cells of the gastric mucosa atypical cells, unlike the healthy.These cells are rapidly dividing and become the basis for the development of malignant tumors.
Histological examination allows you to set the cellular composition of tumors, and therefore the type of tumor.Positive biopsy of the stomach (found malignant cells) is final and is not a final negative, as can be obtained on the basis of studies of healthy tissue, whereas the diseased tissue is taken for analysis has not been.
stomach EGD and biopsy results are crucial in the appointment of a patient of conservative or operative treatment.Type of transaction also depends on the type of cancer Malignant tumor: cells are mad , established during the histological examination.
