Endoscopy is a non-surgical procedure used to examine a person’s digestive tract. During an upper endoscopy, an endoscope is easily passed through the mouth and throat and into the esophagus, allowing the doctor to view the esophagus, stomach, and upper part of the small intestine.

Similarly, endoscopes can be passed into the large intestine (colon) through the rectum to examine this area of the intestine. This procedure is called sigmoidoscopy or colonoscopy depending on how far up the colon is examined. A special form of endoscopy called endoscopic retrograde cholangiopancreatography, or ERCP, allows pictures of the pancreas, gallbladder, and related structures to be taken.

Gem Hospital as one of the best endoscopy centers in Coimbatore and Chennai with its pioneering work has itself as the leading health care provider in the fields of Gastroenterology, Robotic surgery, Gynaecology, Urology, etc.


Endoscopy may also be used to treat a digestive tract problem. For example, the endoscope might not only detect active bleeding from an ulcer but devices can be passed through the endoscope that can stop the bleeding. In the colon, polyps can be removed through the scope to prevent the development of colon cancer.

Also, using endoscopy, gallstones that have passed outside the gallbladder and into the bile duct can often be removed.
