Clinical value of acetic acid and indigo carmine staining the gastric mucosal lesions
Objective To evaluate the clinical value of acetic acid and indigo carmine staining in the diagnosis of gastric mucosal lesions. Methods Select 356 cases of high-risk patients, the gastric mucosal stained acetic acid and indigo carmine after conventional electronic endoscopy. The suspicious lesion morphology and color changes wer observed and recorded then biopsy before and after staining. Results The detection rates of low-grade intraepithelial neoplasia, high-grade intraepithelial neoplasia and early gastric cancer in staining group were hinger compared with conventional group(P <0.05). The detection rate of normal and inflammatory gastric mucosal in staining group were lower in staining group were hinger compared with conventional group, the difference was statistically significant(P <0.05). Polypoid lesions accounted for 44.9% of conventional examination detected in staining detected, flat-type lesions Accounted for 55.6% of conventional examination detected in staining detected. Depressed lesions accounted for 63.0%of conventional examination detected in staining detected. Total correct lesion detection rate accounted for 48.7% of conventional examination detected in staining detected. Conclusion The detection rates of early gastric cancer and high-grade intraepithelial neoplasia can be significantly improved by acetic acid and indigo carmine staining.
