Abstract:
Objective:To explore the application value of magnifying endoscope and flexible spectral imaging colour enhancement(ME-FICE)combined with small ultrasound probe in the diagnosis of early gastric cancer and precancerous lesions.Methods:A total of 80 patients with suspected gastric cancer who admitted to Wuhan Red Cross Hospital from April 2021 to April 2022 were selected,and the ME-FICE was used to distinguish positive and/or negative lesions,and then,small ultrasound probe with high-frequency were used to explore the depth of the infiltration of the lesions.After the examination,biopsy should be performed on the obvious position of lesion under FICE mode.The endoscopic mucosal resection(EMR),endoscopic submucosal dissection(ESD)or surgical resection were performed on the lesions according to the different intentions of the positive patients.The result of postoperatively pathological examination was the"gold standard"for diagnosis.Kappa consistency test was used to evaluate the consistency of benign and malignant diagnosis,the assessment of infiltration depth under endoscope and the assessment of infiltration depth after surgery between ME-FICE combined with small ultrasound probe and pathological examination.Results:The sensitivity,specificity and accuracy of ME-FICE combined with small ultrasound probe were respectively 90.63%,79.17%and 83.75%for benign and malignant diagnosis,which were at higher levels.The Kappa value of that was 0.887,which had favorable consistency with the result of biopsy for cases.The sensitivity,specificity and accuracy of ME-FICE combined with small ultrasound probe were respectively 66.67%,90.00%and 81.25%for the assessment of infiltration degree,indicating poor sensitivity and higher level of other indicators,with a Kappa value of 0.803,which had favorable consistency with postoperatively pathological results.Conclusion:ME-FICE combined with small ultrasound probe is suitable for the diagnosis of early gastric cancer and precancerous lesions,which can improve the sensitivity and accuracy of disease diagnosis,and more accurately assess the degree of infiltration before surgery,and provide guidance for subsequently surgical selection and treatment.
