Fiberoptic coloscopy and cytology.
Colonic lavage for cytologic examination was obtained concomitantly with fiberoptic coloscopy during direct visualization of the affected bowe. Ninety-five patients were so studied. There were 61 benign lesions and 34 carcinomas. There were no false positives; abnormal cells were seen in 32 of the 34 carcinomas. It was concluded that this procedure might aid in an accurate histologic diagnosis; when biopsy was not possible, it could enhance the roentgenographic and endoscopic impression, and finally it might give a more complete diagnosis of the true lesion than small or subadjacent biopsies.
