Endoscopy allows doctors to peer through the body of the course. Endoscopy is an examination and inspection of the inside of the body's organs, joints and cavities through an endoscope. An endoscope is a device that uses fiber optics and powerful lens to provide lighting and visualization of the interior of a joint. The part of the endoscope into the body can be rigid or flexible, depending on the medical procedure.

An endoscope uses two fiber optic lines. A "light fiber" carries light in the body cranial cavity and an "image fiber" carries the image of the body cranial to the doctor considers the lens. There is also a separate port, to allow administration of drugs, suction pressure and irrigation. This port can also be used for small folding instruments such as tweezers, scissors, brushes, Snares and baskets for tissue excision (removal), sampling or other diagnostic and therapeutic work. Endoscopes can be used in combination with a camera or camcorder to document images of the inside of the joint or chronicle an endoscopic procedure. The new Endoscopes digital has the opportunities to manipulate and improve the video.

Endoscopy can be used to diagnose various conditions by close examination of the internal organs and physical structures. Endoscopy can also guide therapy and repair, such as removing torn cartilage from the bearing surface of a joint. Biopsy (tissue sampling for pathologic testing) may also be carried out under endoscopic guidance. Local or general anesthesia may be used during endoscopy, depending on the type of procedure.

Internal abnormalities revealed through endoscopy include: abscesses, biliary (liver) cirrhosis, bleeding, bronchitis, cancer, cysts, degenerative disease, gallbladder stones, hernia, inflammation, metastatic cancer, polyps, tumors, ulcers and other diseases and disorders.

Endoscopy is a minimally invasive and carries a small risk, depending on the type of procedure. But these risks are usually much larger than the diagnostic and therapeutic potential for the procedure.

Before the widespread use of endoscopy and diagnostic imaging of most internal conditions can only be diagnosed and treated with open surgery. Until recent decades, exploratory surgery was routinely performed when a patient was seriously ill and the source of the disease is unknown. For example, in some dire cases, the patient's chest or abdomen were surgically opened and examined to try and cause of the disease.

Endoscopy can often be done on an outpatient basis. "Outpatient" means that the procedure does not require hospitalization and acute care and observation and can be performed outside the premises of a hospital. Outpatient procedures performed in hospitals and outpatient centers, the patient to return home or to work within a short time after their procedure.
