目的提高螺旋 CT 对小肠内疝的诊断率。方法对11例经手术证实且术前 CT 资料完整的小肠内疝患者进行回顾性分析,CT 主要后处理方法有多平面重组(MPR)、滑动薄层块最大密度投影(STS-MIP)重组。结果 11例小肠内疝 CT 诊断正确。左侧十二指肠旁内疝表现为胃和胰之间一囊性或囊实性肿块;肠聚集、移位及拥挤、拉伸;肠系膜走行异常,并可见血管充盈增粗,其他肠段移位;疝口、肠梗阻、小肠内疝伴扭转时,还可以显示肠管及附属肠系膜血管的“漩涡征”。结论螺旋 CT 扫描及其后处理技术对小肠内疝具有重要的临床价值。
Objective To improve the diagnosis of small intestine hernia by spiral CT. Methods Retrospective analysis was performed on 11 cases of small intestine hernias confirmed by operation and with preoperative CT data. The main post-processing methods of CT included multiplanar reconstruction (MPR) and maximum density projection (STS-MIP). Results 11 cases of small intestine hernia CT diagnosis correctly. The left duodenal hernia showed a cystic or cystic mass between the stomach and the pancreas; the intestine was aggregated, displaced and crowded and stretched; the mesentery went abnormally and the thickening of the blood vessels was seen. The other bowel segments Shift; hernia mouth, intestinal obstruction, small intestine with hernia with torsion, but also can show the intestinal and ancillary mesenteric vessels “whirlpool levy ”. Conclusion The spiral CT scan and its post-processing technique have important clinical value on the small intestine internal hernia.
