双重染色内镜在消化道早癌诊断中的重要价值

目的：探讨双重染色内镜在消化道早癌中的诊断价值。方法：选取2009年1月~2010年12月间在丰台医院消化内镜中心进行胃肠镜检查的患者1 880例,分为观察组（406例）和对照组（1 474例）,其中观察组进行内镜下醋酸-卢戈碘液、醋酸-美兰的双重染色,并行病理检查;对照组采取经验性活检取材病理检查,观察两组差异性。结果：观察组中,食管黏膜染色213例,总检出率为15.5%,早癌4例,中重度非典型增生及食管早癌检出率为8.0%;对照组588例,总检出率3.1%,中重度非典型增生及食管早癌检出率为1.2%,两组比较差异有高度统计学意义（P〈0.01）;观察组胃黏膜染色109例,总检出率66.1%,早癌7例,中重度非典型增生及早期胃癌检出率为24.8%,对照组548例,总检出率8.6%,中重度非典型增生及早期胃癌检出率为1.6%,两组比较差异有高度统计学意义（P〈0.01）;观察组肠黏膜染色84例,总检出率79.8%,早癌1例,中重度非典型增生及结直肠早癌检出率为10.7%,对照组338例,总检出率19.8%,中重度非典型增生及结直肠早癌检出率为0.6%,两组比较差异有高度统计学意义（P〈0.01）。结论：内镜下醋酸-卢戈碘液、醋酸-美兰的双重染色法可提高消化道早癌及癌前病变的检出率,具有较高应用价值。

Important value of double staining endoscopy in diagnosis of early digestive tract cancer

Objective: To investigate the value of double staining endoscopy in the diagnosis of early digestive tract cancer.Methods: 1 880 patients who had received gastrointestinal endoscopy examination in the digestive endoscopy center of Fengtai hospital from January 2009 to December 2010 were selected and divided into the observation group(406 patients) and the control group(1 474 patients).The observation group received the endoscopic double staining of acetic acid-Lugol's iodine solution and acetic acid-methyle...
