Abstract
Objective To explore the diagnostic value of combined blue laser imaging-magnifying endoscopy(BLI-ME)and gastric pit morphology-based Sakaki typing for gastric lesions.Methods A retrospective analysis was conducted on the clinical and imaging data of 169 patients with gastric lesions who were treated at a certain hospital from January 2020 to December 2023.An EG-L590ZW magnification electronic endoscope system was used to perform BLI-ME examinations in combination with LASEREO blue laser endoscopy technology and the VP-4450HD high-definition image processing unit.The agreement rates and Kappa coefficients were calculated between the pathological diagnosis and five examination methods respectively,including standard white-light magnification,blue laser imaging-high contrast(BLI-contrast)magnification,blue laser imaging-bright(BLI-bright)magnification,BLI-contrast magnification combined with Sakaki typing and BLI-bright magnification combined with Sakaki typing.ROC curves were employed to evaluate the diagnostic performance of the aforementioned methods for gastric cancer.Results A total of 186 lesions were detected in 169 patients,with a cancer detection rate of 8.06%.The agreement rates between the results of pathological diagnosis and BLI-contrast magnification,BLI-bright magnification and standard white-light magnification were 79.03%,82.80%and 65.59%respectively,the Kappa coefficients were 0.668,0.731 and 0.474 respectively,and the AUC values were 0.816,0.855 and 0.720 respectively.BLI-contrast and BLI-bright magnification examinations had high agreement rates with the pathological diagnosis and high diagnostic efficacy for gastric cancer.When combined with Sakaki typing,BLI-bright and BLI-contrast magnification examinations had the agreement rates with the pathological diagnosis being 97.85%and 96.77%respectively,the Kappa coefficients being 0.863 and 0.795 respectively,the sensitivity being 98.25%and 97.66%respectively,the accuracy being 97.85%and 96.77%respectively and the AUC values being 0.958 and 0.922 respectively,with BLI-bright magnification examination gaining advantages over BLI-contrast in diagnostic efficacy and agreement rate with the pathology diagnosis.Conclusion BLI-ME demonstrates high sensitivity and accuracy in the diagnosis of gastric lesions,and gastric pit morphology-based Sakaki typing reflects the nature and severity of the lesions,thus the combination of them facilitates the early detection and precise diagnosis of gastric cancer.[Chinese Medical Equipment Journal,2026,47(5):70-77]关键词
