Abstract:
Objective To explore the value of oral ultrasonic contrast agent on preoperative T staging of gastric cancer.Methods 62 patients diagnosed with gastric neoplasms by operation and pathology were analyzed retrospectively.Patients were treated by oral ultrasonic contrast agent and conventional ultrasonography before surgery,two methods were compared with postoperative pathology.Results Oral ultrasonic contrast agent and conventional ultrasound detection rates of gastric neoplasms were 100.0 ％(62/62)and 64.5 ％ (40/62),The difference was significant between the two examination methods(x2 =24.369,P ＜ 0.05).The oral ultrasonic contrast agent and conventional ultrasound with T1,T4 staging accuracy rates were 85.7 ％(6/7),0,92.3 ％(36/39),59.0 ％(23/39),there were significant differences(both P ＜ 0.05).T2,T3 staging accuracy rate were 75.0 ％(3/4),0,83.3 ％(5/6),33.3 ％(2/6),the differences were not significant(P =0.143,P =0.242).Conclusion Oral ultrasonic contrast agent in preoperative T staging diagnosis has higher accuracy rate in gastric neoplasms,it could guide clinical rational therapy.It is worth promoting non-invasive,convenient means of stomach diseases census.
