Abstract
The overall yield provided by use of the flexible fiberoptic sigmoidoscope is 3.2 times greater than that of examinations with the rigid sigmoidoscope. More than twice (2.4 times) the number of polyps and more than 3 times the number of cancers were detected with the flexible fiberoptic sigmoidoscope. Experienced endoscopists can perform an examination with the flexible fiberoptic sigmoidoscope expeditiously in the office with minimal patient preparation, a high level of patient and physician acceptance and relative safety when the usual mandatory colonoscopic precautions and guidelines are obeyed. The extraordinary advantages warrant wide clinical application of the flexible fiberoptic sigmoidoscope. Provision should be made for appropriate training of physicians in the use of the instrument.
