ABSTRACT

Rectoscopy and sigmoidoscopy are now firmly established as the scientific method of examining the terminal segment of the large intestine. In patients having symptoms referable to the large bowel, it is no longer a question of the value of rectoscopy and sigmoidoscopy, but of the simplest and most efficient instrument for this purpose. Hitherto the practical methods of direct electric illumination of the proctoscope have been by carrying small incandescent bulbs near the distal end of the tube on insulated carriers.

Previous attempts at direct illumination of proctoscopes by a light within and at the proximal end of the tube have been few and the resulting instruments complicated and unpractical. Recently, however, Dr. James R. Hayden ingeniously conceived a new principle of thus lighting a tube and his idea has been cleverly executed in the Hayden urethroscope. By his courtesy I have adapted the same system of lighting to the
