Colonoscopy

Colonoscopy is a test which allows the doctors to look directly the lining of the large bowel. The colonoscope is a long flexible tube with a bright light at the end. The tube is carefully passed through the anus to the large bowel. This method differs from a sigmoidoscopy, which only examines the lower third segment of the colon. The doctor gets a clear view of the lining of the bowel and can check whether any disease is present or not. Sometimes the doctor takes biopsies i.e. small pieces of tissues are removed painlessly through the colonoscopy by using tiny forceps.

Oesophago-Gastro-Duodeno-Scopy (OGDS)

The term "endoscopy" refers to a special technique for looking at the upper gastro-intestinal (GI) tract (the digestive system), that includes the esophagus, the stomach, and the duodenum. The esophagus carries food from the mouth for digestion in the stomach and small intestine.

Upper GI endoscopy is a procedure performed by a gastroenterologist, or general surgeon who uses the endoscope to diagnose and, in some cases, treat problems of the upper digestive system.

The endoscope is a long, thin, flexible tube with a tiny video camera and light at the end. By adjusting the various controls on the endoscope, the Doctor can safely guide the instrument to carefully examine the inside lining of the upper digestive system.
The high-quality picture from the endoscope is shown on a TV monitor; it gives a clear, detailed view. In many cases, upper GI endoscopy is a more precise examination than X-ray studies.

Upper GI endoscopy can be helpful in the evaluation or diagnosis of various problems, including difficult or painful swallowing, pain in the stomach or abdomen, bleeding, ulcers and tumors. Tiny instruments can be passed through an opening in the endoscope to obtain tissue samples, coagulate (stop) bleeding sites, dilate or stretch a narrowed area, or perform other treatments.
