摘要 胃肠道间质瘤是起源于胃肠道Cajal间质细胞的腹腔内间叶源性肿瘤。发病率为1/10万,性别无明显差异[1]。大多数胃肠道间质瘤发生在胃(60.0%),其次为小肠(30.0%)和结肠/直肠(5.0%)。在形态学上可分为梭形细胞型(70.0%)、上皮样细胞型( 20.0 %)和混合型(10.0%)[2]。影像学检查是诊断胃肠道间质瘤的重要辅助检查方式,增强CT检查对胃肠道间质瘤的大小、位置、边界情况及有无邻近器官受累提供了有价值的信息,但对肿瘤体积较小的胃肠道间质瘤却容易发生漏诊。近年来,随着内窥镜技术的广泛应用,越来越多的胃肠道间质瘤能被早期发现,提供了早期根治肿瘤的机会。同时,基于内镜技术衍生的多种创新型治疗方式已被广泛用于胃肠道间质瘤的治疗。现将胃肠道间质瘤的内镜诊治进展作一综述,旨在为临床工作提供参考。
