The Preoperative Endoscopic Ultrasonography Staging and Its Clinical Pathological Texture Feature in Patients Gastric Cancer

In order to study the clinical value of small probe endoscopic ultrasonography (EUS) in preoperative pathological staging and pathological texture features of gastric cancer, we selected some patients with gastric cancer to prospectively analyze and all patients were confirmed by postoperative pathological examination. The postoperative pathology and preoperative texture analysis were compared so as to determine the difference in pathological stage and depth of tumor invasion. The results have shown that the coincidence rate of preoperative EUS judgment and postoperative pathology degree was: the coincidence rate of 1/3 of the lesion site was 90.00%, the coincidence rate of middle 1/3 was 89.47%, and the coincidence rate of the lower 1/3 was 95.65%; Diameter: the coincidence rate of ≥3 cm is 91.84%, the coincidence rate of <3 cm is 89.09%; the type of lesion differentiation: 82.80% of differentiated type, 72.73% of undifferentiated type; Kappa value = 0.680, P < 0.001. Therefore, EUS has a high degree of consistency and coincidence with pathology in preoperative pathological staging and pathological features of gastric cancer.
