多层螺旋CT对小肠梗阻病因的诊断价值

The value of multi-slice spiral CT in the etiological diagnosis of small intestinal obstruction

目的:评价多层螺旋CT对小肠梗阻病因的诊断价值。方法:41例小肠梗阻病例进行了上下腹部CT平扫加增强扫描,利用工作站获得重建图像,并将CT结果与手术病理对照。结果:41例小肠梗阻患者均经手术证实,其中良性病变29例(包括胆石性梗阻,腹外疝或腹内疝,粘连性肠梗阻,肠气肿,炎性纤维性息肉,粪便纤维素性梗阻,肠套叠伴良性病变,小肠克罗恩病),恶性病变12例(包括胃癌术后转移,原发性或继发性小肠恶性肿瘤,结肠恶性肿瘤,肠套叠伴恶性病变)。多层螺旋CT正确诊断梗阻病因39例(95.1%),误诊漏诊2例。结论:多层螺旋CT是诊断小肠梗阻病因的有效且较准确的方法。

Objective： To evaluate the value of multislice spiral CT in the etiological diagnosis of small intestinal obstruction. Methods： Forty one patients of small intestinal obstruction performed pre-contrast and contrast MSCT scans. CT data was transmitted to workstation and reconstruction was performed. CT findings were compared with pathologic findings. Results： AU cases included twenty nine benign lesions （gallstone obstruction, hernia, adhesive obstruction, intestinal emphysema, inflammatory fibroid polyp, phytobezoar, intussusception, Crohn disease） and twelve malignant lesions （abdominal metastasis after gastric cancer resection, malignant small or large intestinal tumor）. The cause of obstruction was correctly diagnosed by MSCT in thirty nine cases （95.1% ）. Two cases were misdiagnosed. Conclusion： MSCT is effective and accurate for diagnosing the causes of small intestinal obstruction.
