Gastroscopy is the procedure where an endoscope is inserted into the stomach to examine the inner lining of the oesophagus, stomach and the first part of the small intestine called the duodenum. It is one of the commonest procedures performed.
Many patients suffer from abdominal pains and/or bloating sensations. Many symptoms are caused by stomach problems, so the endoscope is a very convenient and accurate way of confirming or excluding stomach ailments as the cause of the symptoms. Because the procedure is so easy to perform and has a very good safety profile, it is used frequently to aid in the diagnosis of conditions such as gastritis, peptic ulcer disease, oesophageal reflux disease, duodenal ulcers, tumours and the presence of Helicobacter pylori which is a bacteria that causes gastritis.
Prior to the procedure, you will need to fast for four hours in order to empty the stomach of any food material. At the Endoscopy room, you will be given some intravenous sedation.
Once asleep, the endoscope is inserted into the mouth and is navigated into the stomach and duodenum. The entire inner lining of the oesophagus, stomach and duodenum are examined carefully. Any suspicious or unusual lesions are biopsied immediately.
The entire procedure is over in less than 10 minutes.
