The Small Bowel: Normal and Pathologic Anatomy

  • Morton A. Meyers


The distinctive course, coiled nature, and position of the small bowel are provided by the mesentery. The most characteristic gross anatomic feature of the jejunum and ileum is their organization into a series of bowel loops, compactly arranged in the midabdomen. In the routine interpretation of small intestinal series, little attention is directed to this unique organization of the bowel. Indeed, the confluence or overlapping of small bowel loops often presents a misleading appearance. Their serpentine, undulating course ordinarily poses a diagnostic challenge in identifying the presence of a localized abnormality.
