胆石性肠梗阻是一种罕见且具有潜在危险性的胆石症并发症,临床表现不典型,术前诊断困难.2005年3月至2012年9月上海市浦东新区人民医院收治了19例经手术或内镜检查证实的胆石性肠梗阻患者.患者术前X线片、超声、CT、MRI检查诊断准确率分别为0/10、0/5、19/19、9/9.CT检查可作为胆石性肠梗阻的首选检查方法.典型的CT表现为Rigler三联征:肠腔异位结石、机械性肠梗阻及胆道积气.MRI检查对瘘口的显示优于CT检查,可提供更为丰富全面的影像学信息,对手术方案的制订及预后的判断有重要参考价值；X线片及超声检查仅作为筛查手段.

Gallstone ileus is a rare and potentially serious complication of cholelithiasis.Its clinical symptoms are nonspecific.From March 2005 to September 2012,19 patients with gallstone ileus confirmed by surgery or endoscopy were admitted to the Pudong New Area People's Hospital.The accuracies of X-ray,uhrasonography,CT and magnetic resonance imaging (MRI) were 0/10,0/5,19/19 and 9/9,respectively.CT examination might be the first choice for diagnosing gallstone ileus ; the classical computed tomography (CT) presentation of gallstone ileus was the Rigler triad,including pneumobilia,ectopic stone and mechanical ileus; MRI examination was superior to CT examination in exposing the fistula,and can provide abundant information,which is important for designing the surgical procedures and judging the prognosis; X-ray and ultrasonography are beneficial in screening the diseases.
