What is endoscopy?

Endoscopy is a medical procedure used to view the digestive tract, and other internal organs, without an operation. Using an endoscope (a thin rubber tube with a lighted camera attached), the internal body structures can be seen enlarged on a video monitor by the doctor.

Where is the endoscope inserted?

The endoscope can be inserted through the mouth (upper endoscopy or EGD), or through the rectum (colonoscopy)

When is endoscopic testingrequired?

It is done to diagnose the cause of abdominal pain, acidity, gas, loss of appetite, change in bowel habits, piles and bleeding. Diseases such as ulcers, esophageal, stomach or bowel cancer, polyps and colitis are easily diagnosed using endoscopy.

How can I get an endoscopy done at Sunrise hospital?

You may see Dr Rajeev Jayadevan, Dr Joby Augustine or Dr Jiffy Rasak in consultation and then get scheduled for endoscopy.

Can I get both consultation and endoscopy done on the same day?

If you wish to have an endoscopy done, it is better to call earlier and schedule an appointment. Walk-in endoscopy can also be done, but only on days with lighter schedules.

Do I need to book an appointment to see the doctor?

We see both walk-in patients, as well as those who book by appointment. You may book an appointment by calling +91 484 2660004, 9946001005 (for OP visits) or 9633954446 (for endoscopy).

Do I need to starve before an endoscopy?

You should not have eaten solid food for at least 8 hours prior to upper endoscopy. However, you may have water or black tea/coffee up to 2 hours prior to the procedure.

How should I prepare for a colonoscopy?

Detailed instructions will be given at the hospital at the time of scheduling, along with the medicines required to do the bowel preparation. You should be on clear liquids (water, Sprite, black tea/coffee, clear juice without pulp) as directed prior to colonoscopy. You should arrive at the hospital at least an hour before your appointment.

Are there any limitations after endoscopy?

Since it is done under IV sedation, you should not drive a motor vehicle for 24 hours after the procedure. There is no restriction on diet.

Is sedation mandatory?

No. In fact, the majority of endoscopies in India are done without sedation. However it is more comfortable to undergo the procedure under gentle IV sedation, which incidentally is the accepted standard in America.

What is a screening colonoscopy?

It is done on healthy persons over age 50, looking for polyps (small growths on the bowel wall) which are the earliest form of colon cancer. One out of 4-5 people over age 50 have polyps, which are silent, without symptoms. Removal of polyps at colonoscopy will greatly reduce the risk of colorectal cancer, which is the no.2 cause of cancer deaths worldwide, and one of the few genuinely preventable cancers. Countries like America, Europe, Singapore and China are already doing it as part of their routine health check-up at age 50.
