The small bowel is a tubular organ 3–7 m in length, which starts at the pylorus and terminates at the ileocecal valve. At the duodenojejunal flexure (the so-called ligament of Treitz), the duodenum becomes continuous with the intra-abdominal small intestine. Just by convention, the jejunum comprises the upper two-fifths of the intraperitoneal small intestine, and the distal three-fifths are designated as the ileum. There is no clear border between the jejunum and ileum, but a continuous reduction of Kerckring’s folds and an increase in the visibility of vessels can be observed at small bowel capsule endoscopy (SBCE). Landmarks are the retrograde view of the pylorus, the duodenal bulb, the papilla, the terminal ileum with lymph follicles, and the ileocecal valve. Variants of normal include lymphatic cysts, venectasias, and lymph follicles. This chapter provides an overview and typical images.
