EndoscopyEndoscopy means looking inside and typically refers to looking inside the body for medical reasons using an endoscope, an instrument used to examine the interior of a hollow organ or cavity of the body. Unlike most other medical imaging devices, endoscopes are inserted directly into the organ. Endoscopy can also refer to using a bore scope in technical situations where direct line of-sight observation is not feasible.
An Endoscopy is a simple procedure which allows a doctor to look inside human bodies using an instrument called an endoscope. A cutting tool can be attached to the end of the endoscope, and the apparatus can then be used to perform surgery. This type of surgery is called Key hole surgery, and usually leaves only a tiny scar externally.
An upper GI endoscopy is done in patients having problems in swallowing, frequent heartburn, abdominal pain, chest discomfort, vomiting especially of blood or abnormal findings on gastrointestinal X-rays. Colonoscopy is performed on patients passing blood in the stools, to check for colon cancer and to remove precancerous lesions such as polyps.
Endoscopy helps the doctor to make a more accurate diagnosis of diseases of the gastrointestinal tract. In addition, endoscopy can be used to provide treatment like removing foreign bodies, benign tumors such as polyps, opening up of strictures, removing obstructed gallstones and stopping active bleeding from ulcers or from dilated veins called varices.
