What is an upper endoscopy and how does it work?
A doctor may use an upper endoscopy to examine the inner linings of the upper digestive tract (the stomach, esophagus and duodenum). This test is also sometimes called an esophagogastroduodenoscopy, or EGD.
An endoscope is a flexible, thin tube that has a light on one end and a small camera on the other. The tube is inserted through your mouth and down your throat into your stomach, small intestine, and stomach. It could be colon cancer treatment.
What is the purpose of an upper endoscopy and why do you need it?
This test can help to identify the cause of any problems in your stomach, esophagus or duodenum. This test may be performed if you have symptoms such as difficulty swallowing, heartburn or feeling full quickly. It might also be necessary to examine an abnormal area on an imaging test (e.g., an x-ray)
An endoscopic ultrasound can include upper endoscopy to examine the walls of the digestive system and any structures that may be nearby. If there is a tumor, such as in the stomach wall or esophagus, the ultrasound can show the extent of its growth and whether it may have reached nearby lymph nodes. Endoscopic ultrasound can be used from the small intestine to examine the gallbladder, pancreas and bile ducts. It could be colon cancer treatment.
An endoscope with a tiny ultrasound probe at its tip is used to perform this test. The probe is passed into the stomach and can be pointed in various directions to view the walls, lymph nodes, and other structures. The ultrasound emits sound waves and detects the echos that bounce off these structures. These echoes are then converted into an image on a computer monitor. A hollow needle can be passed through an endoscope to examine suspicious areas, such as large lymph nodes. It could be colon cancer treatment.
Upper endoscopy may be combined with x-rays in order to examine and sometimes treat problems within the pancreas or bile ducts.
An endoscope is used to test the test. The tube (or small catheter) is passed through the endoscope into the common bile drain. A small amount of contrast dye is then injected through this catheter. As x-rays are taken, the dye helps to outline the bile ducts and pancreatic tubes. It can also show blockages. During an ERCP, the doctor may also take tissue and fluid samples. There is something suspicious about your area. It could be colon cancer treatment.
Upper endoscopy is used to collect biopsy samples from the stomach, esophagus and small intestine. This can be done in order to determine if there are any cancerous areas. To collect the samples, long thin instruments such as pincers or forceps are passed through the endoscope. The lab then examines the samples.

- Upper endoscopy complications
- Although upper endoscopy can be performed safely, there are some risks.
- Bleeding at a site where tissue samples were removed by a doctor
