Pancolonic indigo carmine dye spraying for the detection of dysplasia in ulcerative colitis.
BACKGROUND AND AIMS Colonoscopic surveillance for cancer in longstanding extensive ulcerative colitis relies heavily on non-targeted mucosal biopsies. Chromoendoscopy can aid detection of subtle mucosal abnormalities. We hypothesised that routine pancolonic indigo carmine dye spraying would improve the macroscopic detection of dysplasia and reduce the dependence on non-targeted biopsies. PATI...
متن کاملPancolonic chromosomal instability precedes dysplasia and cancer in ulcerative colitis.
Patients with long-standing ulcerative colitis (UC) are at increased risk for colon cancer. These cancers are thought to arise from preexisting dysplasia in a field of abnormal cells that often exhibits aneuploidy and p53 abnormalities. Using dual color fluorescence in situ hybridization with centromere probes and locus-specific arm probes for chromosomes 8, 11, 17, and 18, we demonstrate that ...
متن کاملThe use of indigo carmine for dye dilution curves.
Investigation of the properties of indigo carmine reveals that it may be more suitable than the dye, T-1824, for circulator}' studies that are now commonly carried out using the dye dilution principle of Stewart and Hamilton. Comparison is made of simultaneous dilution curves of indigo carmine and radioactive iodinated serum albumin. Apparently, indigo carmine is bound to protein firmly enough ...
متن کاملPhotocatalytic Degradation and COD Removal for Indigo Carmine Dye Using aqueous Suspension of Zinc Oxide
This paper reports on photocatalytic decolorization of a hazardous indigo carmine dye solution. The photocatalytic decolorization was carried out in the presence of the catalyst ZnO. The effect of catalyst dose, pH and initial dye concentration on the degradation process has been assessed. The aqueous dye solution was degraded in a photochemical reactor in the presence of UV light (365nm) along...
متن کاملDetection of Polyps Including Adenomas in the Ascending Colon by Cap-assisted Chromocolonoscopy with Indigo Carmine
chromocolonoscopy using indigo carmine increases the detection of colorectal polyps remains controversial. Additional indigo carmine spraying during cap-assisted colonoscopy is expected to improve the detection rate of colon polyps, especially adenomatous polyps. Therefore, this study aimed to evaluate the usefulness of cap-assisted chromocolonoscopy in the proximal colon for routine colonoscop...
