EndoscopyIn simple terms endoscopy means 'to look inside'. In this procedure an endoscope is used to view the interior portion of the gastrointestinal tract. The endoscope is paired with a monitor and it relays images from within the body to the screen. In case a pathology is detected the doctor performs a biopsy or other minor procedures with the instruments present in the endoscope.

If the scope is passed from the mouth to look at the food pipe and stomach it's called gastroscopy and if it is used to look at the bile duct it's called ERCP.

In case the scope is passed from the rectum it's called 'colonoscopy'.

Know the symptoms

Endoscopy is generally performed for patients with the following complaints:

Endoscopy symptoms
  • Persistent abdominal pain
  • Prolonged symptoms of nausea and vomiting
  • Unexplained bloating of the stomach
  • Severe and frequent heartburn
  • Difficulty in swallowing
  • Vomiting blood or granular particles
  • Passing black or tarry stools
  • Unexplained loss of appetite/weight
  • Passing of stool with blood
  • Infrequent bowel motions
  • Jaundice

Procedure step-by-step

  • You will be administered a local anesthetic before the test begins and a sedative may be administered if required.
  • You will then be made to lie on your side or back in a comfortable position as the endoscope is gently passed through your gastrointestinal tract.
  • The esophagus, stomach and duodenum or the colon (during colonoscopy) are then thoroughly examined.
  • Air is introduced into your stomach during the procedure to allow a better view of the stomach/colon lining. The procedure usually lasts 15 - 30 minutes.


Why is an endoscopy performed?

Endoscopy is performed to evaluate symptoms of persistent abdominal pain, nausea, vomiting, and difficulty in swallowing or heartburn.

What sort of preparation is required prior to surgery?

  • You should have nothing to eat or drink for approximately 6 hours before the examination (gastroscopy?ERCP).
  • Before a colonoscopy you will need to take laxatives as prescribed by your doctor to clear your bowels.
  • Use of aspirin, blood thinners and insulin should be discussed with the surgeon prior to the examination.

What happens after the procedure?

You will be monitored in the endoscopy area for 30 – 60 mins hours until the effects of the sedatives have worn off, post which the surgeon will discuss the results of the procedure with you.
