Comparative study of ultrasonic contrast and endoscopic ultrasonography in preoperative staging of gastric cancer.

Objective: To investigate diagnostic value and clinical significance of ultrasonic contrast and endoscopic ultrasonography in preoperative staging of gastric carcinoma. Methods: 65 patients with gastric cancer were randomly selected from our hospital from February 2015 to February 2017 as the study objects and all of them were treated with ultrasonic contrast and endoscopic ultrasonography followed by the comparison of accuracy rate of diagnosis of preoperative staging of gastric cancer between the two kinds of examination methods. Results: There was no significant difference in the accuracy rate of diagnosis of T1, T2, T3 and T4 and total consistent rate of T staging between the two methods (P > 0.05); the accuracy rate of diagnosis of N1, N2 and N3 and total consistent rate of N staging of ultrasonic contrast were significantly higher than those of endoscopic ultrasonography (P<0.05) with no significant differences in the accuracy rate of diagnosis of N0 (P > 0.05) between the two examinations; and the total accuracy rate in the diagnosis of M0 and M1 and total consistent rate of M staging of ultrasonic contrast were significantly higher than those of endoscopic ultrasonography (P<0.05). Conclusion: Ultrasonic contrast has some advantages in the T staging, N1, N2, N3, M1 and M0 and endoscopic ultrasonography N0, both of which therefore have good application value in diagnosis of preoperative staging of gastric cancer.
