Upper Endoscopy (EGD)

Upper endoscopy or EGD refers to a test that allows the physician to see the inside of the stomach. The test is done with a flexible device called an endoscope. The test is performed with sedation, this sedation in the great majority of patients allows for no recall of the event which takes about 10 to 15 min. The test can be performed in an outpatient center or in the hospital. The image sensor on the tip of the endoscope can be manipulated in several directions, up, down, left, right. High quality images are displayed on a video monitor (see samples below). Therapeutic procedures can be performed with the endoscope, such as biopsies, injections, dilations, and methods to stop bleeding.

Colonoscopy is a test used to examine the colon. Colonoscopy is similar to upper endoscopy except the device is different as the colon has a different shape and the instrument is designed to specifically handle this task. The test requires a specific preparation (see downloads) to clear the colon of the waste so that the colon can be visualized. This test requires sedation and takes about 20 to 30 min. but this time can vary depending on the pathology or findings during the exam. See colonoscopy tab for more detailed information about this important test.

This procedure is similar to colonoscopy but limited to the left colon (looking at the rectum, sigmoid colon and despite the name the descending colon). This procedure can be done with or without sedation.

Pillcam (capsule endoscopy)

This test is unique in that an endoscope is not used. This test utilizes a capsule that is ingested by the patient. The capsule then takes pictures and transmits the images to a receiver belt or array that the patient wears. This test is an outpatient test performed in the clinic side of the medical facility. This test specifically photographs the esophagus and small bowel and unlike the other endoscopic procedures there is no method to control the capsule nor is there any way to deliver treatment via the capsule.

This acronym refers to Endoscopic Retrograde Cholangio-pancrreatography a test that uses a specific type of endoscope to allow the gastroenterologist to access the biliary and pancreatic ducts (drainage tubes for the liver and pancreas). The instrument allows the gastroenterologist to insert catheters and other devices into the ducts allowing contrast dye injection and then obtain images using X-ray equipment. Therapeutic measures can be performed such as removing gallstones, or placing stents (drainage tubes). This test is performed typically in the hospital due to the need for high quality X-Ray equipment, dedicated nursing support unique to this test and in many cases the level of sedation for the patient may require the support of an anesthesiologist. GA of Southeast Missouri does not provide this test but refers patients to centers with a reputation of providing expert quality and years of experience in performing this procedure.

EUS or Endoscopic ultrasound allows the physician to take ultrasound images from inside the digestive system. This is usually a hospital based endoscopic procedure. This test requires extensive training beyond the typical gastroenterology fellowship training. This test is not provided at GA Endoscopy and the physicians at GA of Southeast Missouri refers patients to centers with a reputation of providing expert quality and years of experience in performing this procedure.
