Fundamentals of large bowel anatomy related to the problems of DCBE

  • Giorgio Cittadini


In this chapter, several aspects of the large bowel macro- and microscopic anatomy will be considered which acquire particular importance when carrying out the DCBE procedure and for its interpretation, namely:
  • the three-dimensional lay-out of the various colon segments, which affects barium and air collection depending on patient’s decubitus;

  • the ileocecal valve, which may either take a dependent or nondependent position with respect to its attachment in the cecum, thus affecting proper barium filling of the last ileal loop;

  • the morphology of the semilunar folds and the haustral pouches [1], which becomes important in the assessment of impaired colon motility;

  • the colon sphincters;

  • the innominate grooves.
