Sigmoidoscopy with flexible electronic endoscopy: a preliminary experience in Hong Kong

Eighty-two cases of electronic flexible sigmoidoscopy were performed from October 1984 to October 1985 in a rural hospital in Hong Kong. The scope is a relatively new type of flexible endoscope, which has no optical fibre bundle for imaging. The image is taken with a solid state television camera and relayed via a videoprocessor to a television monitor. The image quality and ease of handling were satisfactory. Acceptance by the endoscopy team and the patients was good. The differences in comparison with conventional fibrescopes and television systems are discussed.
