Abstract:
Objective To evaluate the diagnostic value of electronic staining endoscopy combined with endo -scopic ultrasound(EUS) in the preoperative early gastric cancer .Methods A total of 17 patients diagnosed with intramucosal carcinoma by ordinary gastric endoscopy combined with pathological findings were selected ,who under-went the T staging by EUS and electronic staining endoscopic examination before ESD .The findings were compared with pathological findings.Results 17 cases were diagnosed with gastric cancer in T1 stage by EUS(12 cases limited mucous layer or mucosal muscular layer ,5 cases involving the submucossa ) .14 cases were diagnosed with gastric cancer in T1 stage by pathological examination (11 cases limited mucous layer or mucosal muscular layer ,3 cases involving the submucossa ) ,3 cases in T2 stage had received surgery .The accuracy of EUS in determining the depth of intramucosal carcinoma invasion was 88.2%;The total accuracy of T staging was 82.4%.The lesions border was more clear in electronic staining mode ,and easier marked.Conclusion The diagnostic value of electronic staining endoscopy combined with endoscopic ultrasound in the preoperative early gastric cancer is high .
