Our doctors use an endoscope – a long, hose-like optical device that is inserted directly into a body cavity or organ – to examine the health of your digestive system and diagnose or confirm various conditions and diseases. Endoscopic examinations of the upper part of your digestive system – the esophagus, stomach and beginning of the small intestine – can reveal ulcers, hiatal hernias and gastroesophageal reflux disease, also known as GERD.
Narrow-band imaging, a technology for endoscopes, uses special light to better detect precancerous conditions, such as Barrett's esophagus. Improved visibility allows gastroenterologists to decide on the best treatment (endoscopic or surgical) and the management of any conditions.
To create images, an ultrasound can be combined with an endoscopy by attaching an ultrasound probe to the endoscope. This combination is useful to take pictures of the wall of the esophagus or stomach, as well as hard to reach organs.
During the procedure, you’ll receive an intravenous sedative or other form of anesthesia. Then, your provider administers a numbing spray to your throat and inserts a mouthguard to protect your teeth. You will lie on your left side while your doctor guides the endoscope through your mouth and down into the esophagus, stomach and duodenum. Air will be pumped through the endoscope into the stomach and duodenum to make it easier for your physician to see. The procedure takes about 30 minutes.
