Oral ultrasonic contrast agent applied in quantitative diagnosis of gastric carcinoma

目的探讨胃窗超声造影在胃癌定量诊断中的应用价值。方法对100例经胃镜确诊为胃癌患者术前超声检查并与术后病理结果对照。结果超声对胃癌T分期的总准确率为78.0%,其中T1-T4各期判断准确率分别为50.0%、73.3%、83.0%、76.9%;胃壁浸润范围小于7.0 cm和大于7.0 cm及弥漫浸润型胃癌(皮革胃)判断符合率分别为87.5%、81.2%、100%。结论胃窗超声造影对胃癌的定量诊断为患者术前TNM分期提供了重要依据,对临床选择治疗方案和手术方式均具有一定的指导意义。

Objective To investigate clinical value of oral ultrasonic contrast agent applied in quantitative diagnosis of gastric carcinoma. Methods 100 patients with gastric carcinoma （GC） pioved by gastroscope underwent preoperative oral ultrasonic contrast agent ultrasonography and were enrolled in this study, ultrasonograFhic examination comparatively with pathological diagnosis operation. Results The diagnostic coincidence rate of the eroded depth in the four stages, T1 to T4 was 50.0%, 73.3%, 83.0% and 76.9% respectively, and the total rate was 78.0%. The coincidence rate of infiltrative range （distance of the stomach wall from ntima to serosa） less or larger than 70mm and diffuse infiltrative was 87.5%, 81.2% and 100% respectively. Conclusions QD ultrasonography provides important basis for dividing different phases of cases with GC before operation. It has certain clinical guiding effects in method of treatment and surgical excision way.
