Department of Gastroenterology

Gastroenterology is the branch of medicine whereby the digestive system and its disorders are studied. The name is a combination of three Ancient Greek words gaster (gen.: gastros) (stomach), enteron (intestine), and logos (reason). Diseases affecting the gastrointestinal tract, which includes the organs from mouth to anus, along the alimentary canal, are the focus of this specialty.

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 physician.

Where is the endoscope inserted?

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

Why is an endoscopy performed?

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 Padmakumar or Dr Pai in consultation and then get scheduled for endoscopy. The procedure will be performed by Dr Rajeev Jayadevan by appointment.

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.

When is the doctor available?

The doctor is available 9 am-1 noon and 4-6 pm weekdays, and 9-1 noon on Saturdays. You may call +91 484 2428913- 6028 to confirm.

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 2428913- 6028

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) for 24 hours prior to colonoscopy, starting from the previous morning. That afternoon, you may take the prescribed laxative at home. You should arrive at the hospital next morning, 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 much more comfortable to undergo the procedure under light 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 3-4 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.
