The medical name for upper endoscopy is esophagogastroduodenoscopy or EGD for short. The endoscope is a thin flexible tube about the diameter of a fat pencil that has a video chip in the end and channels for flushing of water, suctioning of secretions and passage of instruments. It has dials that allow the tube to be turned up/down and right and left at the tip permitting it to be passed through the mouth, down the esophagus or feeding tube, into the stomach and then into the first part of the small intestine the duodenum, hence the name EGD.

 

Endoscopy in celiac: Do you feel it or remember it?

 

People undergoing the exam in the U.S. typically are sedated with a medication. Medications similar to valium with good amnesia and relaxing effect called midazolam or versed combined with a narcotic like meperidine (demerol) or fentanyl are generally used. More recently a very short acting intravenous sedative, propofol (diprovan), may be administered for deep sedation or an intravenous form of general anesthesia. Occasionally, usually in very young children or people with severe lung problems, general anesthesia is required. The exam is usually not felt or remembered because of the medications.

 

Endoscopy in celiac: What is examined in celiac and how well can the lining be seen?

 

Celiac disease affects the upper portion of the small intestine, in the two sections known as the duodenum and jejunum. The examination of the small intestine is usually limited to the first section termed the duodenum though occasionally the second section known as the jejunum may be reached especially when a longer endoscope is used. The resolution of video images are very high with the latest endoscopes and also may have a magnification and color contrast mode to detect very subtle signs of damage of the small intestine.
