Abstract:Abstract: Objective?To evaluate the diagnostic value of blue laser imaging (BLI) and flexible spectral imaging color enhancement (FICE) for early gastric cancer.?Methods?The clinical data of patients who suspected gastric cancer and precancerous lesions under plain white light endoscopy were collected from December 2017 to February 2018. BLI and FICE were performed in each patient. Endoscopic images were evaluated according to the VS criteria. Microscopic examination was performed using pathology as the gold standard. Chi-square test was used to evaluate the consistency of BLI and FICE with pathological diagnosis, then evaluate the diagnostic value on early gastric cancer and precancerous lesions.?Results?72 patients were included. Nine cases of cancerous lesions were finally identified. The coincidence rate of BLI microscopy and pathology was 98.61% (71/72), and the FICE was 90.28% (65/72). The difference was statistically significant (χ2?=?4.17, P?0.05).?Conclusion?Compared with FICE, BLI has good consistency with pathological results. BLI can more accurately evaluate early gastric cancer and precancerous lesions, which has certain value for accurate diagnosis under microscope.
