Several improvements have been made in a Yeomans' proctoscope to facilitate operative proctoscopic instrumentation and particularly to simplify and broaden the scope of surgical endothermy, when these are indicated, in the treatment of such conditions as rectocolonic neoplasms, ulcerations and strictures.

The improved proctoscope has been enlarged to a 1½-inch inside diameter, and is 8 inches in length. Anesthesia is obviously necessary in using a proctoscope of these dimensions.

Along the lower wall of the proctoscope a one-fourth inch tube has been introduced extending to within three-eighths inch of its distal end, and projecting one-half inch beyond the proximal end (fig. 1, A-B). This tube is particularly designed for suction removal of smoke produced during surgical endothermy and cauterization. A tonsil suction apparatus serves this purpose admirably. This tube can be used also for inflation if desired. Its proximal end is corrugated for the reception of a rubber tube.
