Abstract： 目的 探讨电子肠镜下靛胭脂黏膜染色联合黏膜切除对大肠侧向发育肿瘤(LST)诊治的临床价值.方法 对4200例肠镜检查中发现的可疑黏膜病灶,行镜下喷洒0.4%靛胭脂黏膜染色,镜下观察病灶大小并形态分型,病灶黏膜可随充吸气变形者及黏膜下注射液体黏膜抬举征呈阳性者行内镜黏膜切除(MER)或分片黏膜切除术(EPMR),未能行黏膜切除者行镜下活检,病灶黏膜送病理检查.结果 发现45例患者共47个LST病灶,检出率为1.1%.分型;颗粒型33(70.2%)和非颗粒型14(29.8%).大小;10～19 mm 25个(53.2%),20～30 mm 14个(29.8%),＞30 mm 8个(17.0%).病理检查黏膜局部癌变7例(5例SM癌,2例SML癌),LST病灶中早期大肠癌捡出率为14.9%,进展期大肠癌3例,良性腺瘤37个(78.7%).结论 普通电子肠镜结合黏膜染色能够有效的发现大肠LST病灶,联合镜下黏膜切除根除LST病灶对早期大肠癌防治具有积极临床意义.
