What is Gastroscopy? 

Gastroscopy is a procedure to examine the oesophagus, stomach and duodenum (first part of the small intestine). It is a flexible scope introduced via the mouth into the oesophagus (swallowing tube) then stomach and then the duodenum or beginning of the small intestine. It is usually performed under sedation (sleep induced by intravenous medication) so you will be asleep and unaware of the procedure, in an endoscopy room. During gastroscopy, a soft flexible telescope camera tube is inserted through the mouth and into the stomach and duodenum. It is also known as an OGD or upper endoscopy.

Why is a Gastroscopy performed?

Gastroscopy is performed to evaluate upper abdominal pain, vomiting, difficulty in swallowing, heartburn, chest pain or black stools (upper gastro-intestinal bleeding).

Before Gastroscopy, you should be fasted for 4-6 hours. Your doctor may instruct you to take some of your existing medicines (e.g. medicines of high blood pressure, asthma etc.) and omit other medicines (e.g. diabetic medicines, anti-platelets, anti-coagulants etc.).

In the endoscopy room, your throat will be sprayed to numb your throat. A cannula will be inserted into a vein, sedative will be given through this route and you will fall asleep. After this, the procedure will be commenced. The scope is inserted via your mouth into your oesophagus, stomach and duodenum. Air will be used to distend the stomach (an air channel is built into the scope) so that we can see clearly. Suction is also available (built into the scope) so that fluid can be sucked out. If any abnormality is seen (e.g. ulcer, gastritis or cancer), a small bite of tissue (about 1-2 mm) can be retrieved with a biopsy forceps for microscopic examination. Larger polyps can also be removed for microscopic examination.

After the procedure, you will be monitored for 1-2 hours before you are ready for discharge. Do not drive or operate machinery for make important decisions for 24 hours as the sedatives will affect your judgement. Please also make arrangements for someone to bring you home.

Your doctor will be able to tell you his findings immediately. If a biopsy has been taken, the results should be ready in 2-3 days. Sometimes if the scope is normal and so cannot explain your symptoms, your doctor may recommend additional tests such as an ultrasound or CT scan.

What is an Endoscope?

A flexible scope is a long, thin, flexible tube about 1 cm in diameter and about 1 to 1.5m long that is designed to be introduced into a natural orifice (mouth or anus) and be advanced forward to view one or more internal organs.

A scope has a video camera at its tip that sends a live video image to a monitor. It also has a channel to blow air or suck fluid and take biopsies or remove polyps.

Stomach Cancer Screening:

The incidence of stomach cancer has decreased drastically over the last 30 years in Singapore. Whereas it used to be 120 per 100000 per year, it is now about 12 per 100000 population per year. This is in no doubt due to Helicobacter Pylori detection and eradication. With such a low incidence, it is not worthwhile to conduct population based screening.

Screening for gastric cancer consists of yearly gastroscopy and biopsy for intestinal metaplasia and dysplasia and should be repeated every year unlike colon cancer. Nevertheless, some groups who have higher risk should consider screening. This would include-

  1. Those with a close relative who has had stomach cancer and should start screening at an age 10 years earlier than when the relative was diagnosed.
  2. Those with certain types of stomach polyps (adenoma) and should start screening from diagnosis.
  3. Those of certain ethnic origin e.g. Japanese, Korean, Northern Chinese, Alaskan, from the age of 50 years.
  4. Those with chronic H. Pylori even after eradication and intestinal metaplasia.

Indications for a Gastroscopy:

  1. Upper abdominal pain or bloating
  2. Difficulty in swallowing
  3. Nausea or vomiting
  4. Gastro-oesophageal reflux
  5. Upper gastro-intestinal bleeding (black stools or occult blood or anaemia)
  6. Screening or evaluation of abnormal findings from blood tests or x-rays

The Symptoms

Patients who are young (under 40 yr. old) and have abdominal pain or reflux may be managed with medication initially and that is all that may be needed initially, unless the problem persists beyond 2 weeks despite treatment. They should however have a scope immediately if they have any of the following upper GI alarm symptoms:

  1. Difficulty in swallowing
  2. Nausea or vomiting
  3. Upper gastro-intestinal bleeding (black stools or occult blood or anaemia)
  4. Unintended loss of weight or appetite

Patients with these alarm symptoms should go for a gastroscopy immediately as there may be an underlying malignancy.
