Analysis of the accuracy and influencing factors of narrow-band imaging magnifica-tion endoscopy in preoperative prediction of the depth of invasion in superficial esophageal squamous cell carcinoma(B2 type)
Objective To elucidate the accuracy and influencing factors of narrow-band imaging magnifying endoscopy-based preoperative prediction of the depth of infiltration in superficial esophageal squamous cell carcinoma(S-ESCC)by using the JES classification system.Methods We retrospectively analyzed 140 patients diagnosed with S-ESCC in our hospital from Jan.2018 to Apr.2023.The patients were categorized into B1(84 cases),B2(53 cases)and B3(3 cases)types based on the preoperative ME-NBI endoscopic diagnosis.The diagnostic efficacy of different JES classifications for S-ESCC was assessed using a 2×2 diagnostic software.Logistic regression and forest plot analysis were employed to eval-uate the transitional diagnosis and diagnostic insufficiency associated with the B2 vascular type.Results The diagnostic efficacy of different JES classifications for S-ESCC varied.The positive predictive value(PPV)and accuracy for B1,B2,B3 types were 88.09%and 68.79%,28.30%and 67.37%,66.66%and 95.37%,respectively.Among the JES clas-sifications,the diagnostic efficacy was lowest for the B2 type.Logistic regression analysis revealed a significant increase in the occurrence of small-area B2 and B2 with inflammatory erosion in patients with the EP/LPM type compared to those with the MM/SM1 type(P<0.05).Furthermore,the occurrence of significant endoscopic features was significantly low-er in patients with the MM/SM1 type compared to those with the SM2/SM3 type(P<0.05).Conclusion The B2 vas-cular type exhibits lower diagnostic efficacy for S-ESCC.Small-area B2,B2 with inflammatory erosion and significant en-doscopic features are the main distinguishing factors between the MM/SM1 type and other types.
