There are several types of GI endoscopy, including:
Esophagogastroduodenoscopy (EGD) - examines the esophagus, stomach, and the first part of the small intestine. Colonoscopy - examines the entire colon and rectum. Sigmoidoscopy - examines the rectum and the lower part of the colon. Endoscopic Ultrasound (EUS) - combines endoscopy and ultrasound to obtain images of the digestive tract and surrounding tissues.
