Endoscopy is a minimally invasive diagnostic tool, used to view the inside of organs, inspect for abnormalities and take biopsies. A small camera and light source are mounted onto a flexible tube which can be inserted into the mouth (to inspect the esophagus, stomach and duodenum) or the anus (to inspect the large bowel).test

Upper Endoscopy

Upper endoscopy is usually performed to evaluate symptoms of persistent upper abdominal pain, nausea, vomiting, or difficulty swallowing. It is also the best test for finding the cause of bleeding from the upper gastrointestinal tract.

Upper endoscopy is more accurate than x-ray films for detecting inflammation, ulcers, or tumors of the esophagus, stomach and duodenum. Upper endoscopy can detect early cancer and can distinguish between benign and malignant conditions when biopsies of suspicious areas are obtained. Biopsies are taken for many reasons and do not necessarily mean that cancer is suspected.

Upper endoscopy is also used to treat conditions present in the upper gastrointestinal tract. A variety of instruments can be passed through the endoscope that allow many abnormalities to be treated directly with little or no discomfort, for example, stretching narrowed areas, removing polyps (usually benign growths) or swallowed objects, or treating upper gastrointestinal bleeding. Safe and effective endoscopic control of bleeding has reduced the need for transfusions and surgery in many patients.
