Flexible fiberoptic sigmoidoscopy in a surgeon's office.

The use of the flexible fiberoptic sigmoidoscopy in an office setting in 116 consecutive patients detected 18 polyps beyond the reach of the rigid sigmoidoscope. Three of these polyps were Dukes' A lesions. Cancer surveillance and resolution of questionable x-ray findings were improved with this new instrument. Anastomoses, diverticula and inflammatory bowel disease were more easily surveyed. With the use of proper technique, the procedure is safe and well tolerated by the patient.
