常见消化道瘘的影像学表现--肠外瘘

2015-02-03 首都医科大学附属北京朝阳医院 蒋涛 中国医学论坛报

肠外瘘形成的原因主要是手术所致,胃、十二指肠手术等均可造成术区与皮肤之间形成瘘管,另外克罗恩病、重度阑尾炎等是形成瘘管的常见原因。 影像学检查首选瘘管造影和CT检查。瘘管造影是经皮肤瘘口注入造影剂,可显示纤细迂曲或粗大的不规则瘘管影,并与腹腔肠管或胃腔相通,瘘管形态与流出量密切相关,量较多时瘘管多较粗大,反之瘘管则较纤细。 CT平扫及增强扫描可以发现胃肠手术部位或腹腔病变部位与皮肤

肠外瘘形成的原因主要是手术所致,胃、十二指肠手术等均可造成术区与皮肤之间形成瘘管,另外克罗恩病、重度阑尾炎等是形成瘘管的常见原因。

影像学检查首选瘘管造影和CT检查。瘘管造影是经皮肤瘘口注入造影剂,可显示纤细迂曲或粗大的不规则瘘管影,并与腹腔肠管或胃腔相通,瘘管形态与流出量密切相关,量较多时瘘管多较粗大,反之瘘管则较纤细。

CT平扫及增强扫描可以发现胃肠手术部位或腹腔病变部位与皮肤之间管道相通,周围由于炎症刺激可出现明显炎性改变或周围脓肿形成。

对于脓肿的显示,CT明显优于瘘管造影,并可引导手术穿刺引流。

肠外瘘的临床知识点

肠外瘘特点:消化道瘘包括肠外瘘、胆瘘与胰瘘,其中危害最大的是肠外瘘。消化道外瘘中的胆瘘漏出的是胆汁,胰瘘漏出的是胰液,肠瘘漏出的是肠液。胆汁本身无消化能力,胆汁漏出后对机体的影响主要是刺激作用。漏出的胰液如无激活,对机体的影响仅为水电解质丢失的影响。肠液因内含细菌和已激活的各种胰酶,其对机体的病理生理影响远较单纯胰液和胆汁的危害要大。 因肠液内含有大量细菌,肠液外溢后,可引起严重腹腔感染
