Endoscopy can also help identify inflammation, ulcers, and tumors.
Upper endoscopy is more accurate than X-rays for detecting abnormal growths and for examining the inside of the upper digestive system. The improved accuracy is especially important if you have had upper-digestive-tract surgery in the past.
During the procedure, a physician uses an endoscope (a long, thin, flexible instrument about 1.5 cm or 1/2 inch in diameter) to examine the inside of the upper digestive system.
Abnormalities can be treated through the endoscope. Polyps (usually benign growths) can be identified and removed, and tissue samples (biopsies) can be taken for analysis. Procedures such as stretching narrowed areas, removing swallowed objects or treating bleeding from the upper digestive system can also be performed as part of upper endoscopy.
