A gastroscopy, also called an upper gastrointestinal endoscopy, is a medical test used to diagnose and treat diseases of the upper digestive system. This painless procedure involves using a thin, flexible tube with a camera and light on the end, which is inserted through the mouth into the esophagus, stomach and first part of the small intestine.
The gastroscopy procedure first requires the patient to fast for a period of time, usually overnight, to ensure that the stomach is empty and the procedure can be performed effectively. On the day of the procedure, patients are usually given a sedative to help them relax and minimize any discomfort during the procedure.
Once the patient is ready, the gastroenterologist carefully inserts the endoscope into the mouth and guides it through the upper gastrointestinal tract. A camera at the end of the endoscope transmits images to a monitor, allowing doctors to examine the lining of the esophagus, stomach, and duodenum in real time. This allows doctors to identify any abnormalities such as inflammation, ulcers, tumors or bleeding.
In addition to its diagnostic function, gastroscopy can also be used for medical treatment, such as removal of polyps or tissue samples for biopsy. The entire procedure usually takes about 15 to 30 minutes, and the patient is briefly monitored afterwards to ensure there are no complications from the sedation.
Understanding the entire process of a gastroscopy can help reduce any anxiety or fear associated with the procedure. It is important to follow the preoperative instructions provided by your medical team and communicate any concerns or medical conditions to the doctor performing the gastroscopy. Overall, gastroscopy is an important tool in the diagnosis and treatment of upper digestive system disorders, and its painless nature makes it a relatively comfortable experience for patients.
