Analysis of clinical application value of micro probe endoscopic ultrasonography in patients with resectable esophageal cancer

Objective To explore the clinical application value of micro probe endoscopic ultrasonography (MPS) in the diagnosis of resectable esophageal cancer.Methods We selected 70 patients with esophageal cancer from January 2017 to January 2020 as research subjects. All the patients underwent magnetic resonance diffusion weighted imaging and MPS. According to the examination method difference, they were divided into the magnetic resonance diffusion weighted imaging group (DWI group) and MPS group. The final diagnosis result is obtained by biopsy of the surgical specimen.Results The length of the esophageal cancer lesions in the DWI group was (47.45 ± 9.34) mm. Compared with the final result, the lengths of the esophageal cancer lesions in the DWI group were significantly longer, and the values were significantly different (P < 0.05). The length of the esophageal cancer lesion was (42.56 ± 8.56) mm. Compared with the final result, the length of the esophageal cancer lesion detected in the MPS group was slightly different (P > 0.05). There were 21 cases, 35 cases, 9 cases and 5 cases were diagnosed with T₁, T₂, T₃ and T₄ stage respectively in MPS group, and 25 cases, 31 cases, 12 cases and 2 cases were diagnosed with T₁, T₂, T₃ and T₄ stage respectively in DWI group. There was no significant difference between MPS group and DWI group (P > 0.05). The detection sensitivity, specificity, and accuracy of the DWI group were 86.73%, 72.45%, and 83.65%, respectively. The diagnostic value of the MPS group was 87.34%, 89.03%, and 97.34%. Compared with the DWI group, the diagnostic specificity and the accuracy of the MPS group were significantly higher (P < 0.05), but the difference in sensitivity between the two groups was small (P >0.05). The AUC value of patients with esophageal cancer detected by DWI was 0.748, the AUC value of patients with esophageal cancer detected by MPS was 0.803, and the diagnostic value of MPS for esophageal cancer was higher.Conclusion Compared with DWI, the MPS has a better diagnostic effect for patients with resectable esophageal cancer, and can more accurately determine the length of esophageal lesions.
