An endoscopy is a diagnostic procedure where a scope will be inserted into the body in order to get a view inside an organ or a part of the body. This is a visual form of diagnosis that uses the doctor’s skill to identify a potentially harmful abnormality which can then be subject to further testing. An endoscopy is usually ordered after a person has reported some symptoms that prompts the doctor to want to look into that area of the body for clues as to what is causing the symptoms. The endoscopy procedure is carried out by accessing the internal organs using the mouth, the anus or the opening of the urethra as points of access to the organs that need to be studied. An endoscope is used to penetrate the body and it passes into the body until it has reached the desired area. The scope contains a lighting device and magnifying lenses at inside end. Some scopes also allow for surgical instruments to be passed within the same tubing as the endoscope. This allows for tissue samples to be collected from the area that is being examined. An endoscopy procedure may make use of a rigid or flexible endoscope. The flexible scope is less painful to an individual while the rigid scope may be necessary if a surgical procedure needs to be done while the scope is in place.
Endoscopy is an invasive procedure. This means that there is a risk of problems occurring as the process of inserting a foreign object is not normal for the body. There is a risk that the area being scoped might get damaged by the scope which can cause a tear in the tissue or a more serious perforation. This occurs when inexperienced technicians are conducting the test or when there is a serious blockage in the way of the scope which may be ruptured when the scope comes into contact with it.
There is no major preparation required for an endoscopy procedure. The only thing needed, in case of an endoscopy through the anus is a clean bowel. This will be done by consuming a strong laxative that will empty out the bowels. Patients may be partially sedated during the procedure; hence they may need a friend or family member present in order to return home after the procedure. The doctor should also be informed of any unrelated symptoms or allergies that may be affected by the test.
