Fibroscopy: indications and course of the examination
When one thinks of fibroscopy, one thinks almost systematically of digestive fibroscopy whereas there are nevertheless several types. The process is almost identical, the inside of an organ or part of the body is examined through the introduction of an endoscope, which is why the examination is sometimes called endoscopy. This instrument is a flexible tube at the end of which is a small camera and a lamp. If necessary, fibroscopy can also be used to perform a biopsy by taking a fragment of a lesion or mucosa for analysis. This is a painless test but can be uncomfortable.
Bronchial fibroscopy: an exploration of the lungs
Bronchial fibroscopy, also known as bronchoscopy, involves exploring the trachea and bronchi. It can be prescribed in case of suspicion of a bronchial cancer in order to look for a tumor but can also be recommended in the case of an inflammation or an infection. The examination is performed under local anesthesia by a pneumonologist who will introduce the probe through the mouth or nasal passages. The outpatient copyscopy lasts between 10 and 20 minutes.
Digestive fibroscopy: stomach, esophagus and duodenum with a magnifying glass
Upper digestive fibroscopy, or oeso-gastroduodenal, is indicated to search for inflammation, infection, hiatal hernia, ulcer, tumor, but also digestive stenosis, ie a narrowing of the upper digestive tract. The doctor may prescribe it in case of bleeding, gastro-oesophageal reflux, abdominal pain or persistent digestive disorders. Digestive fibroscopy is performed under local anesthesia, more rarely under general anesthesia, by a gastroenterologist who will introduce the probe through the patient's mouth.
It lasts between 5 and 15 minutes, sometimes more if it is accompanied by a levy. It may happen that it is performed at the same time as a colonoscopy, which is another type of fibroscopy which this time concerns the lower part of the digestive tract and requires the introduction of the probe through the rectum. As for bronchial fibroscopy, the patient must be fasting.
Urinary fibroscopy: examination of the bladder and urethra
Also called cytoscopy or bladder endoscopy, urinary fibroscopy is used primarily in the diagnosis of bladder cancer, to look for polyps or inflammations but can also be prescribed in case of repetitive urinary tract infections or bleeding. It allows to visualize the bladder and the urethra, as well as the prostate in the man. This examination can be performed under general or local anesthesia by a urologist who will introduce the fiberscope, coated with anesthetic gel, through the urinary tract. Cytoscopy lasts about 30 minutes.
