1、胃癌前哨淋巴结定位及活检技术探讨【摘要】目的:研究并探讨对胃癌患者进行前哨淋巴结定位及活检的可行性和临床价值。方法:选取2011年1月-2015年1月笔者所在医院进行胃癌根治手术的100例患者作为研究对象,在手术过程中,使用亚甲蓝前哨淋巴结进行定位活检,对其定位活检结果进行分析,并与术后病理诊断结果进行对比。结果:100例患者中被检出前哨淋巴结转移84例,检出率为84%。术后病理诊断结果显示,100例患者中早期胃癌34例,中晚期胃癌66例;而84例被检出前哨淋巴结转移患者中,早期胃癌32例,屮晚期胃癌52例。早期胃癌定
2、位活检的敏感度为94.12%,屮晚期胃癌定位活检的敏感度为78.79%,定位活检对早期胃癌的敏感度较中晚期胃癌明显更高,差异有统计学意义(P〈0・05)。结论:对胃癌患者进行前哨淋巴结定位活检,具有较高的检出率,R其诊断早期胃癌的准确性高于中晚期i'j粘L【关键词】胃癌;前哨淋巴结;定位活检;术后病理诊断中图分类号R735.2文献标识码B文章编号1674-6805(2015)26-0021-02DiscussionoftheLocationofSentinelLymphNodesinGastricCancerandIt
