胶囊内镜与双气囊小肠镜对小肠疾病诊断价值的研究 |
|
因操作简单、容易吞咽、无痛苦、无交叉感染、检查费用相对低等优点,目前它既可作为一项诊断检查,又可作为双气囊小肠镜检查前的初筛性检查,指导双气囊小肠镜的检查进镜路径。双气囊小肠镜由于进镜原理的创新性,在通常情况下可抵达回肠中下段,部分可达末端回肠,检查范围大大扩展,且具有视野广、图像清晰和充气、吸引、活检等基本功能,并可行内镜下治疗[10];其上行和下行镜相结合的进镜方式能使整个小肠得到全面、彻底的检查,它是大多数小肠疾病检查理想的手段。但是从目前累积的经验分析,双气囊小肠镜检查亦有一定的盲区,如肠黏膜皱襞后方、肠瓣后方观察较为困难甚至可能遗漏病灶。此外双气囊小肠镜对患者配合度要求较高,不适于进行常规小肠疾病筛查。因此,宜根据临床实际情况灵活应用胶囊内镜和双气囊内镜,以提高小肠疾病的诊断。
