The SAGES Video Atlas of Endoscopy has been created to assist surgical endoscopists to recognize benign and malignant pathology of the GI tract. The videos are not procedural, but intended to fill any knowledge gaps when viewing normal and abnormal pathology. There are six categories of videos: 1. Airway. 2. Colon. 3. Duodenum. 4. Esophagus. 5. Small Bowel. 6. Stomach. Comments are encouraged and welcomed.
