title: A low-cost method for chromoendoscopy for surveillance in ulcerative colitis.
abstract: The risk of colorectal cancer in Indian patients with long-standing ulcerative colitis is high and similar to that in the West. Surveillance for dysplasia in these patients is therefore important. Recent studies and guidelines suggest an increasing role for chromoendoscopy-guided biopsy in surveillance for dysplasia. We report our experience with the technique of chromoendoscopy and an economical method of performing it. Reconstituting indigo carmine from a powder form rather than the dyes available commercially is a better economical alternative and should help make chromoendoscopy the standard of care for dysplasia surveillance across the country.
