● Gastroscopy procedure is performed under sedation as per the convenience of the patient. In this procedure, the numbing spray is used to numb the throat to avoid gaging and a mouth guard is placed to protect teeth. After numbing a thin flexible tube called a gastroscope or endoscope is inserted into the mouth and guided into the oesophagus, stomach and duodenum part of the small intestine for the examination. Air is blown into the stomach to inflate it for better vision.
● The endoscope/ gastroscope contains a light and video camera that transmits images to a monitor for examination by the doctor.
● After examination, the gastroscope is pulled out slowly. This whole procedure takes 15-45 minutes.

○ Stopping gastric bleeding
○ Placement of stents and dilation of the narrow oesophagus
○ Placement of feeding tubes in the stomach
○ Dissolution or removal of indigestible material in the stomach
● Diagnostic gastroscopy is used for:
○ Checking the cause of the symptoms presented by the patient like abdominal pain, difficulty in swallowing or acid reflux.
○ Confirming the diagnosis like stomach ulcers and gastro-oesophageal reflux disease (GORD)
● Diagnostic gastroscopy is usually completed in 15 minutes.
● When gastroscopy is used for treating, it is called therapeutic gastroscopy. It is used for:
○ Removing a tissue for biopsy in case of suspected cancerous growths
○ Removal of small growths like polyps
○ Sealing the bleeding veins by the use of chemicals or bands
○ Treating bleeding stomach ulcers
○ Widening of oesophagus
○ Laser treatment of oesophageal cancer
○ Dissolution of indigestible material in the digestive tract
○ Placement of feeding tubes in the stomach
● Therapeutic gastroscopy takes more than 15 minutes depending upon the treatment. It is usually completed in 15-45 minutes.
After the gastroscopy procedure patient will experience bloating and throat pain temporarily for a couple of hours. Gastroscopy is a safe procedure for the examination of the upper gastrointestinal tract. The patient can notice the improvement in symptoms in case of treatment done during the gastroscopy procedure.

Gastroscopy is also known as upper endoscopy, is used for the examination of the lining of the oesophagus, stomach and beginning of the small intestine (duodenum). In this diagnostic procedure, a gastroscope attached with a light and a camera is inserted through the mouth of the patient to examine the upper gastrointestinal tract.
Gastroscopy is a safe diagnostic procedure. The patient will experience bloating and sore throat for a couple of hours after the examination. Other rare complications of gastroscopy are:
● Perforation of the lining of the oesophagus, stomach and duodenum.
● Abdominal and chest pain
● Difficulty in swallowing
● Reaction to sedation
Inserting gastroscope through the mouth can cause gagging and vomiting. The numbing spray is used to numb the throat and sedation is used to relax the patient for a comfortable experience. Numbing and sedation reduce gagging and vomiting during the procedure. So there is minimal to zero chances of vomit during the procedure.
Yes, gastroscopy is used for both diagnosing and confirming the diagnosis of cancer of the upper gastrointestinal tract. It is also used for collecting tissue from the abnormal growth on the inner lining of the oesophagus, stomach and duodenum. It is also used for removing polyps that can turn into cancerous growth.
Special instructions are given to the patient before gastroscopy examination for a clear view of the stomach during the procedure and to prevent unwanted complications. Before the examination patient is advised to:
● To stop or adjust ongoing medications at least a week before the procedure
● Do not eat 6 to 8 hours, and stop drinking 2 to 3 hours before the procedure
