小肠梗阻的MSCT诊断

目的探讨小肠梗阻的CT诊断特点。方法收集2011年2月～2012年10月小肠梗阻病例45例,,均行64层螺旋CT扫描,仅做平扫者12例,平扫加增强者33例,必要时采用MPR、CPR、VRT及MIP等后处理方法进行图像重建,回顾性分析45例经手术或临床证实的小肠梗阻的CT和临床资料。结果在45例病例中。CT检查敏感性为100％,定位诊断准确率为91．1％,病因诊断正确率为86．7％,均有肠管呈节段或普遍性扩张积液、积气的表现,因梗阻原因不同而CT表现有所不同。结论CT是诊断肠梗阻的有效方法,对小肠梗阻CT征象的较好理解将有助于提高诊断准确性并帮助临床及时制定治疗方案。     

Acute small bowel obstruction due to bilharziasis

Schistosomiasis remains a major world health problem. The disease presents with protean manifestations in the endemic areas. Small bowel schistosomiasis leading to acute intestinal obstruction is an extremely rare clinical presentation. The disease may mimic peritoneal tuberculosis or carcinomatosis intra-operatively. Small bowel bilharziasis leading to obstruction has not been reported in the recent indexed English literature. This report describes a 50-year-old Yemeni male presenting with acute small bowel obstruction due to schistosomiasis. We review the pathological changes in the intestine following schistosomal infection and discuss diagnosis and treatment. We emphasize the importance of histopathology on all surgical specimens.
