A gastroscopy, also known as an upper endoscopy, is a medical procedure used to examine the inside of the esophagus, stomach, and duodenum. It is performed using a thin, flexible tube with a camera attached to it. The tube is inserted through the mouth and down the throat into the digestive system. The camera allows the doctor to view the lining of the esophagus, stomach, and duodenum for any abnormalities.
Gastroscopy is a common procedure that is used to diagnose a variety of conditions, including:
- Ulcers
- Inflammation
- Cancer
- Gastroesophageal reflux disease (GERD)
- Hiatal hernia
- Infections
- Polyps
- Bleeding
Gastroscopy can also be used to treat some conditions, such as:
- Remove polyps
- Stop bleeding
- Place a stent in the esophagus to widen it
Gastroscopy is usually performed as an outpatient procedure, which means that you can go home the same day. The procedure is usually performed under sedation, which means that you will be relaxed but not asleep.
What to Expect During a Gastroscopy
The gastroscopy procedure usually takes about 15-20 minutes. Before the procedure, you will be asked to fast for at least 8 hours. You will also be given medication to help you relax.
During the procedure, you will be lying on your left side. The doctor will insert the tube through your mouth and down your throat. You may feel some discomfort as the tube passes through your throat, but this should not be painful.
Once the tube is in place, the doctor will inflate your stomach with air. This will help them to get a better view of the lining of your stomach. The doctor will then examine the lining of your esophagus, stomach, and duodenum for any abnormalities.
If any abnormalities are found, the doctor may take a biopsy. This is a procedure in which a small sample of tissue is removed for testing.
After the procedure, you will be monitored for a short time before you are allowed to go home. You will be given instructions on how to care for your throat and what to eat and drink.
Recovery from a Gastroscopy
Most people recover from a gastroscopy within a few days. You may experience some sore throat or bloating after the procedure. These symptoms should go away within a few days.
It is important to avoid eating or drinking anything for at least 2 hours after the procedure. You should also avoid strenuous activity for at least 24 hours.
If you experience any pain or discomfort after the procedure, you should contact your doctor.
A gastroscopy is a safe and effective procedure that can help diagnose a variety of conditions. If you are experiencing symptoms such as heartburn, indigestion, or difficulty swallowing, your doctor may recommend a gastroscopy.
