Abstract
The small bowel is a tubular organ 3–4 m in length, which starts at the pylorus and terminates at the ileocecal valve [1]. In a recent study, the small bowel length measured from the ligament of Treitz to the ileocecal valve was 2.83–3.45 m [2]. It is usually subdivided into the duodenum, jejunum, and ileum. The most proximal portion is the C-shaped duodenum, approximately 25 cm long, which is almost a fixed retroperitoneal structure. Four subdivisions of the duodenum are recognized: the first or superior portion (bulb, D1); the second or descending portion, which includes the papilla of Vater (D2); the third or horizontal portion (D3); and the fourth or ascending portion (D4). At the duodenojejunal flexure (the so-called ligament of Treitz), which is left of the midline at the level of the second lumbar vertebra, 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. The multiple intra-abdominal coils are mobile; they are attached to the mesentery (Fig. 19.1). The diameter decreases from about 25 mm in the duodenum to 19 mm in the distal ileum [3].
The work was first published in 2006 by Springer Medizin Verlag Heidelberg with the following title: Atlas of Video Capsule Endoscopy.
