Radiologic Examination of the Small Intestine.

Abstract

The author introduces this subject with a brief outline of the indications for a radiologic study of the small intestine, a description of his method for carrying out this detailed study and discussion of the use of the small intestinal enema (Schatzki). There follows an account of the known facts of developmental anatomy of the small intestine graphically clarified by four excellent diagrammatic drawings of the stages of rotation of the intestine. He then describes the gross and microscopic anatomy of the small intestine, following with a clear presentation of the present knowledge of the physiology of the various components of the intestinal wall, including a discussion of the intrinsic nervous plexuses, the muscularis mucosae and the chemical mediator theory of the neuromuscular and neuroepithelial mechanism of the intestine. A chapter is devoted to the normal radiologic appearances of the adult small intestine from the standpoint of motility and mucosal
