Abstract

RECENT developments in fiberoptic technology have revolutionized the field of gastrointestinal endoscopy. The endoscopist now can examine in great detail the entire length of the esophagus, stomach, duodenum, colon, and parts of the small intestine. Gastric lesions can be visualized and photographed.58 Biopsy and cytologic specimens can be obtained under direct vision.59-62

The diameter of the gastroscope is only 10 to 11 mm. Sophisticated manipulative systems permit the examiner to direct the distal tip of the gastroscope to specific areas of interest and perform a thorough investigation. External illumination from powerful sources of light and an integral bundle to carry the light into the stomach provide adequate illumination for still photography, cinegastroscopy, and television.63 Magnetic tape recording for instantaneous replay and simultaneous examination by two observers via a teaching attachment serve to train new endoscopists. Review of these tapes and other photographic documents is useful for self-teaching.
