We experienced the examination of the upper GI tract with 16 mm and 8 mm endoscopic color cinematography and color TV-VTR endoscopy in Kinki Univ. Hospital in between 1975 and 1978. The usefulness and evaluation of endoscopic movie and endoscopic television were investigated by screening, routine and functional endoscopy. 1) 16 mm endoscopic color cinematography. The image quality of 16 mm endoscopic color cinematography was excellent and beautiful. But the 16 mm movie camera, Beaulieu R-16,was too bulky and large and it was a professional instrument. If we attached 3 kg to the end of the scope, it immediately interfered with routine endoscopy. The expensiveness of 16 mm endoscopic color cinematography commanded problems also. 16 mm endoscopic color cinematography made them only available to train endoscopic consultants and students and to demonstrate for the conference. 2) 8 mm endoscopic color cinematography. About 10 years ago, the 8 mm movie cameras were improved by Kodak and Fujica. These cameras were lighter and the optical system was of high quality. And then, 8 mm color film was made with ASA ratings of 25 to 400. The illumination for cinematography became brighter and transmission through the scopes improved. At present time 8 mm endoscopic color cinematography is performed as amateur tecnique. We used the Fujica ZC-1000,which is inexpensive and convenient because of the instant loading of cartridges. The Fujica ZC-1000 was smaller and somewhat lighter (2 kg) than the Beaulieu R-16. And the Fujica ZC-1000 was commercially provided with simple attachment devices to various types of Olympus endoscopes. 8 mm endoscopic color cinematography has great advantages for the demonstration of movement of the upper GI tract. The effect of a pelistatic wave of the esophageal diseases was especially investigated. Dye scattering method was also precisely studied by cinematography. 3) Color TV-VTR endoscopy. The great advantage of color TV-VTR endoscopy permits the instant review of the previous endoscopic findings. At first time, there were few merits in case that we used the Olympus TV exclusive endoscopes for color TV endoscopy. Since the GIFtypeP2 was introduced by Olympus in 1976,the GIFtypeP2 has been able to be directly attached to the Toshiba Chalnicon color TV camera. And then screening and routine panendoscopy with the GIFtypeP2 has been done with the aid of color TV-VTR endoscopy. It is beneficial to the prevention of misdiagnosis of the GIFtypeP2's endoscopic findings.
