目的 L/S比值对胃周淋巴结肿大定性的研究。方法 使用SSA—270A,SSA—370A彩色超声显象仪,胃标准切面、纵、横扫查判定病变位置及侵及深度、以十字定位方确认淋巴结并测量长径(L)短径(S) 结果 本组病人胃周淋巴结L/S比值t=7.56 P<0.01,相关系数显著性检验(P<0.01) 讨论 超声对胃周淋巴结肿大L/S比值测定,对良恶性鉴别非常有意义,可进一步探讨,同时对外科术前对胃周淋巴结肿大及良恶性鉴别提供可靠依据。
Objective The L/S ratio is a qualitative study of lymph node enlargement in the stomach. Methods SSA-270A, SSA-370A color ultrasonic imaging system, stomach standard section, longitudinal and transverse scans were used to determine the location and invasion depth of the lesions, lymph nodes were identified by cross-localization, and the long diameter (L) short diameter (S) was measured. The ratio of L/S of gastric lymph node in this group was t=7.56 P<0.01. The significance test of correlation coefficient (P<0.01) was used to determine the L/S ratio of lymph node enlargement in the stomach, and it was very significant to differentiate between benign and malignant tumors. To further explore, at the same time provide a reliable basis for surgical preoperative lymph node enlargement and differentiation of benign and malignant.
