3. Figure 2
Patients with dysplasia detected by technique. Shown is the total number of subjects with dysplasia detected by any of the methods: random biopsy, no-dye targeted, and dye targeted. Ten subjects had colectomies as a result of non-resectable dysplasia. Of those patients 7 were positively identified for dysplasia by dye-targeted method, 2 by both dye-targeted and no-dye targeted methods, and 1 by no-dye targeted method only. One patient had a colectomy for stricturing disease. No colectomies were prompted by random biopsy findings.
