title: Flexible fiberoptic sigmoidoscopy.
abstract: The 35-cm flexible fiberoptic proctosigmoidoscope is a cost-effective instrument for the family physician. Nonendoscopists have mastered its use with no reported complications. Patient tolerance is high compared to tolerance for the rigid scope. The pathology yield per procedure is two to four times greater than that reported with the rigid sigmoidoscope. Yields with the 35-cm instrument have matched those documented with the 65-cm fiberoptic instrument.
