The author presents in an interesting manner the practical application of proctoscopic and sigmoidoscopic examination. In this work he has condensed the material in the first edition and has added new material.
He describes the methods of preparation of the patient and various positions for examination. His preference is the knee-chest position. A brief discussion of the anatomy of the rectum and sigmoid colon follows. The different types of instruments and their accessories are discussed and illustrated. The author prefers projected light rather than that which carries the light forward. In rare cases it is necessary to anesthetize the anus. The pathway of the tube up the bowel is described in detail. Although the author has never had the experience, perforation of the bowel has occurred and should be carefully avoided by being certain that the lumen of the bowel is ahead as the tube progresses.
