Abstract
Malabsorption syndrome is a complex of diseases arising from an abnormality in absorption of nutrients caused by various gastrointestinal disorders. The absorptive function test is one major method of diagnosis, whereas small bowel endoscopy was used as a subsidiary examination because of its complexity before. However, recently two newly developed endoscopy modalities, double balloon endoscopy and capsule endoscopy, have facilitated the observation of the entire small intestinal tract and have contributed greatly to the increased ability to diagnose malabsorption syndrome. Here we present several representative intestinal disorders that cause malabsorption syndrome, especially featuring their characteristic endoscopic findings.
