目的 为提高超声检查对胃癌术前分期诊断的准确性。方法 采用新的TNM分期法对胃癌进行术前分期。胃癌患者 87例 ,同批实验对象 ,以常规超声检查为对照组 ,以口服甘露醇肠腔液性充盈后超声检查为实验组。将超声检查结果与手术病理分期对照。结果 术前胃癌浸润深度T4期的诊断符合率 ,局部腹腔淋巴结转移N1、N2 期的诊断符合率 ,远隔淋巴结转移M1期的诊断符合率和临床胃癌分期Ib～Ⅳ期的诊断符合率 ,实验组均显著高于对照组。结论 实验方法显著提高了胃癌术前分期的准确性 ,所检出的Ⅳ期胃癌 ,应考虑放弃根治性手术
Objective To improve the accuracy of ultrasound preoperative diagnosis of gastric cancer. Methods The preoperative staging of gastric cancer was performed using a new TNM staging method. 87 patients with gastric cancer, the same batch of experimental subjects, routine ultrasound examination as a control group, oral mannitol in the intestine after liquid infusion after ultrasound for the experimental group. Ultrasound examination results were compared with surgical pathological staging. Results The diagnostic coincidence rate of preoperative T4 stage invasive depth of gastric cancer, the diagnostic coincidence rate of N1, N2 phase in local lymph node metastasis, the diagnostic coincidence rate of M1 phase in distant lymph node metastasis and the diagnostic coincidence rate of stage Ib to IV in clinical gastric cancer, experiment The groups were significantly higher than the control group. Conclusion The experimental method significantly improves the accuracy of preoperative staging of gastric cancer. In the detected stage IV gastric cancer, radical surgery should be considered.
