What is upper GI endoscopy?

Upper GI endoscopy is a procedure where an endoscope, or a long flexible tube with a camera mounted on the end, is fed through a patient’s esophagus, stomach, and duodenum. The doctor is able to see the lining of the upper gastrointestinal tract with this procedure, which allows him to diagnose some gastrointestinal disorders accurately. If necessary biopsies can be taken during this procedure. This procedure is often ordered when patients present symptoms like chronic heartburn, nausea, and vomiting, issues with swallowing, pain, and unexplained weight loss. Some of the conditions that can be diagnosed with this procedure include:

• Anemia
• Cancer or precancerous abnormalities
• Celiac disease
• Gastroesophageal reflux disease
• Inflammation
• Ulcers

What is video capsule endoscopy?

Capsule endoscopy uses a tiny wireless camera, which is swallowed by the patient. As the capsule moves through the patient’s digestive tract, it takes thousands of pictures which are transmitted to a recording device that is worn by the patient. This procedure allows a doctor to see inside a patient’s small intestine, an area that is not easily accessible with traditional endoscopy. Capsule endoscopy can also be used to screen the colon for polyps.

What happens during the procedure?

Before an endoscopy is performed, the patient will be advised not to eat or drink for approximately eight hours to ensure that the doctor will be able to see the GI tract clearly. The procedure is usually performed at a hospital or outpatient center. The patient will receive a sedative via an IV to help him or her stay relaxed and comfortable during the procedure. A local anesthetic will be applied to the throat to calm the gag reflex and allow the slim tube to pass more easily through the esophagus. The patient will lie on his or her side on an exam table while the procedure takes place. The procedure takes between 15 and 30 minutes and allows the doctor to see any damage or abnormality in the upper GI tract. Many patients fall asleep during the procedure and experience only minor discomfort in the throat for a day or so after the procedure is completed. During the video capsule endoscopy, the patient will wear receptors on the abdomen, linked to a receptor which is typically worn on the belt. When the device is in place, the patient will swallow the capsule. The doctor will provide advice on eating and activity levels to ensure that the tiny camera can collect the needed images. The capsule should pass naturally within a day or so.
