超声内镜及胃肠超声造影在胃癌术前分期中的临床应用价值

目的 对比分析超声内镜、胃肠超声造影在胃癌检查中的影像特点及术前分期价值.方法 选取2010年10月至2015年10月经手术病理证实为胃癌的患者共168例,对其超声内镜、胃肠超声造影检查的影像学资料进行回顾性分析,并与术后病理结果进行对照.结果 超声内镜术前T分期评估的准确率明显高于胃肠超声造影,差异具有统计学意义(P＜0.05);胃肠超声造影术前N及M分期评估的准确率明显高于超声内镜,差异具有统计学意义(P＜0.05).结论 超声胃镜检查对胃癌原发灶的诊断准确率较高;对胃癌转移灶的诊断,胃肠超声造影检查对胃癌转移灶的诊断效果更好,且均与术后病理分期一致.

Clinical application value of ultrasonic endoscopy and gastrointestinal ultrasonic contrast in preoperative staging of gastric carcinoma

Objective To investigate the imaging features and preoperative staging value of ultrasonic endoscopy and gastrointestinal ultrasonic contrast in the gastric carcinoma examination.Methods One hundred and sixty eight patients with gastric carcinoma verified by operation and pathology in our hospital from October 2010 to October 2015 werecollected.Then their imageological data including ultrasonic endoscopy and gastrointestinal ultrasonic contrast examinations were retrospectively analyzed and compared with the postoperative pathological results.Results The accuracy rate of preoperative T staging in ultrasonic endoscopy was significantly higher than that of gastrointestinal ultrasonic contrast,the difference had statistical significance(P＜0.05);the accuracy rate of preoperative N/M staging in gastrointestinal ultrasonic contrast was s1gnificantly higher than that in ultrasonic endoscopy,the difference had statistical significance(P＜0.05).Conclusion Ultrsonic endoscopy and gastrointestinal ultrasonic contrast have different advantages and values in preoperative staging:ultrasonic endoscopy has higher accuracy rate in the diagnosis of primary gastric carcinoma;gastrointestinal ultrasonic contrast is better in diagnosing metastasis of gastric carcinoma,moreover which shows the consistency with postoperative pathological staging.
