Upper endoscopy can be extremely beneficial for identifying and treating various conditions that affect the upper digestive tract, including anemia and cancers of the digestive system. Unlike surgical techniques, it requires no incisions or stitches.
Upper endoscopy is usually recommended for investigating troublesome digestive symptoms, such as abdominal pain, bleeding, nausea, difficulties swallowing, vomiting, heartburn and ulcers. Upper endoscopy is also used to treat certain problems of the digestive system, which may involve cauterizing blood vessels to stop bleeding or widening a narrow esophagus. In addition to the diagnostic and investigative purposes of an upper endoscopy, the following may be performed:
- Tissue samples can be obtained for biopsy
- Matter lodged in the gastrointestinal tract can be removed
- Therapeutic procedures may be performed
Upper endoscopy may also be combined with other imaging procedures, such as an ultrasound.
