An upper endoscopy is a diagnostic study used to examine the internal lining of the upper portion of gastrointestinal (GI) tract. The upper endoscopy or EGD is used to evaluate the esophagus, stomach and first part of the small intestine (duodenum). A patient may have an EGD as part of a workup for symptoms such as abdominal pain, reflux, difficulty swallowing, nausea and vomiting. It is also used to evaluate for a upper GI bleed or ulcer.
Prior to the procedure, the patient should fast for 8 hours to ensure the stomach is empty. Under sedation, a small flexible camera about the diameter of a finger is placed into your mouth and passed down your esophagus (swallowing tube) and into your stomach. The procedure is relatively quick, about 15 to 20 minutes. Since sedation is used the patient should have a ride home. Once the sedation is out of your system one can return to normal activities. This is typically the next day.
A colonoscopy is a diagnostic study to exam the internal lining of the rectum and large intestine or colon. A patient may have a colonoscopy as part of a workup for abdominal pain, change in bowel habits, blood in the stool or screening for colon cancer.
Prior to the procedure, the patient will complete a bowel prep in order to get all the waste product or stool out of the colon to allow proper visualization. The patient will be sedated for the procedure. A small flexible camera about the diameter of a finger is placed into the rectum and advanced along the large large intestine. It will last about 15 to 45 minutes. The procedure is usually well tolerated. The patient may experience cramping, bloating and gas pressure after the procedure. Since sedation is used the patient should have a ride home. Once the sedation is out of your system one can return to normal activities. This is typically the next day.
