title: Technique of flexible fiberoptic sigmoidoscopy.
abstract: Flexible fiberoptic sigmoidoscopy allows a maximum amount of colon to be examined expeditiously and thoroughly, and it is predicted that this new instrumentation will be used with increasing frequency. Three techniques of intubation of the sigmoid with a flexible fiberoptic sigmoidoscope are discussed: elongation, looping, and "accordionization" or the "dithertorquing" technique.
