An upper GI endoscopy or EGD (esophagogastroduodenoscopy) is a non-surgical procedure used to examine and treat the upper part of your digestive tract. Without resorting to invasive surgery, it explores the esophagus, stomach, and first part of the small intestine (duodenum). An upper GI endoscopy can often identify disorders in their early stages before they become severe.

Push enteroscopy is a procedure that helps find and treat problems most commonly in your upper to middle small intestine. It’s done using a long, narrow, flexible tube called an enteroscope. There are several types of enteroscopes. The tube has a tiny light and a camera on its tip. It connects through a video feed to a screen where the picture is seen in high definition. This lets your healthcare provider see inside your intestine.

A sigmoidoscopy is a diagnostic test used to check the sigmoid colon, which is the lower part of your colon or large intestine. This section of your colon is close to your rectum and anus.

A sigmoidoscopy may also be used to take a tissue sample or biopsy. And it can be used to remove polyps or hemorrhoids (swollen veins in your rectum and anus). It is also a screening test for colon cancer and rectal cancer.

Capsule endoscopy is a procedure that uses a tiny wireless camera to take pictures of the organs in the body that food and liquids travel through. This is called the digestive tract. A capsule endoscopy camera sits inside a vitamin-sized capsule. After it's swallowed, the capsule travels through the digestive tract. The camera takes thousands of pictures that are sent to a recorder worn on a belt around the waist.
